This paper is the third and last of a series of papers (cited elsewhere ) which the writer has submitted to this Society as a preliminary to the preparation of an account of the Natural Regions of South Australia. A well-considered regional division of the State was considered to be necessary for the adequate study of its Human Geography, as well as for general teaching purposes, Such regions could not be erected without a comprehensive survey of the State and its people. The first of the three papers referred to included a study of the geomor- phology and human geography of the Adelaide district—the best known and most thickly settled portion of the State. The second paper dealt with the growth, movement, and achievement of the people during the State’s first ninety years of existence, touching also on the underlying geographic factors. The present (third) paper aims to be purely geomorphological, and to outline the structure, land forms, and drainage systems of the State in the light of modern views on these subjects. The fundamental paper on South Australian physiography is that by Pro- fessor W. Howchin, embodying his Presidential Address to Section C at the meeting of the A.A.A.S., in Melbourne, in 1913. Since then papers on the geo- morphology of this State have been few in number, while structural work has been largely confined to the Palaeozoic and older rocks. The contributions by Howchin, Benson, Taylor, Mawson, Ward, Jack, Teale, Madigan and Hossfeld are men- tioned elsewhere in this series of papers, It will be understood, therefore, that our present knowledge of the details of the latter tectonic movements, and of the present geomorphology of the State, is distinctly limited. The country is a vast one. The workers are lamentably few. To most of these workers other aspects of geological study have proved more attractive. In this paper most of the less known areas are treated in broad detail only, fresh theories are submitted in an endeavour to explain some of the facts in the more critical areas, and an effort has been made to present a unified and modern view of the post-Miocene tectonics and the present physiographic features of South Australia, The writer is indebted to Mr. Wm. Ham for assistance with the proofs, and to Mr. J. A. Tillett for his careful draughtsmanship. II—THE SOUTHERN COASTLINE. The State of South Australia is set within a “square” of the earth’s surface. That is to say, it extends between 12 degrees from cast to west, and 12 degrees from north to south. But while the upper or northern half of this square is practically an unbroken expanse of land, the southern portion is of varied outline, and more than half consists of sca and gulf. The geological history of the State, read in conjunction with the later tectonic happenings, with the prevalence of fault influence on the coastlines and with the abrupt descent of the sea floor to the Jeffrey Deep to the south (fig. 2 D), leaves little doubt that there has been large-scale foundering to the south and south-west. As the writer has elsewhere pointed out (Trans. Roy. Soc. S, Austr., vol, liii., 1929, pp. 82-85), these great subsidences have opened up the southern districts of the State to the oceanic influences of the cyclones and anti-cyclones, greatly to the advantage of the districts concerned, These favourable influences are clearly shown in the rainfall, temperature, and evaporation maps of the State. Thus the heavily indented southern coastline, trending obliquely from latitude 32° 5. to latitude 38° S., and due to post-Miocene large-scale subsidences and uplifts, must be regarded as one of the most important structural features of South Australia.

IIl—THE TECTONIC MOVEMENTS OF THE GULF AND TORRENS AREAS, (a) The “Shatter-belt” of Australia—The most fertile and populous portion of South Australia is the part that is centred about the two southern gulfs, Spencer and St. Vincent. The present physiographic features of these gulf areas are the outcome of certain tectonic movements of considerable extent and importance. 4 Australian geographers and geologists, in a somewhat loose and general way, recognise a division of the island-continent into three major parts: (1) a great stable “shield” of ancient rocks and uniform relief in the west; (2) an eastern portion marked by wide variety of rock types, with sediments of many ages, and with complex physiographic features; and (3) an intermediate separating zone of considerable tectonic disturbance, with Miocene to recent block-faulting and differential uplift, dividing the stable western part from the less stable east. This intermediate zone, or ‘‘shatter-belt,’ has not been definitely delimited, ‘nor even positively demonstrated. Still, the conception is of value for descriptive purposes. The belt characteristically includes the areas of depression and uplift of the gulfs and central highlands of South Australia, and also of the Lake Torrens and North Flinders ranges (vide “The Geography of South Australia,” Howechin and Gregory; and also “Adelaide, South Australia,’ Fenner, Trans. Roy. Soc, S.Austr., vol. li., 1927, pp. 195-200). This zone may be taken to continue northward through the severely down- warped (and possibly faulted) area of Lake Eyre, and thence onward to the McDonnell Ranges. ‘The last-named area has been shown by L. Keith Ward and R. Lockhart Jack, in various Bulletins of the S.A. Mines Department (also Proc. Roy. Soc. S. Austr., vol. xlix., 1925, p. 61, ef. seq.), to be considerably faulted. ‘hence the ‘“shatter-zone” may continue north-westerly, in a gently curving arc, through the little-known and somewhat featureless Tanami country, to the severely block-faulted and mountainous peninsula mass that lies in North-West Australia, between King’s Sound and Queen’s Channel. This latter area includes the King Leopold and allied ranges. The pattern of the river systems there, the character of the mountains, and the type of adjoining coast, alike bear witness to block-faulting and differential uplift along the directions suggested, vwiz., dominantly N.W.-S.E., and subordinately N.E.-S.W. The relief is “strong,” and there has been recent coastal submergence. (b) The so-called “Rift Valley’ of South Australia—tIn the southern portion of this broken zone, which here concerns us most, we have the relatively sunken areas of the Spencer Gulf, Gulf St. Vincent, and Lake Torrens, with the adjoining uplifted land-masses of the Flinders and Mount Lofty ranges. The general structural features of this area have been dealt with in detail by the writer (Trans. Roy. Soc. 5, Austr., 1927, vol. li, Sections ITI, and IV.). In the paper referred to, certain objections were raised regarding the descrip- tion of the above-mentioned sunken area as a Rilt Valley, Further exception may be taken to its popular description as “The Great Valley of South Australia.” It is desired to emphasise this point, and to produce further evidence in support of the suggestion that we are here dealing with a tectonic feature that is not properly described as a “Rift Valley”—nor even as a “Valley.” At the same time, certain points regarding the age and the dynamics of this phenomenon will be considered. In a discussion on this paper at the Royal Society of South Australia (1927), Dr. L. Keith Ward contributed the following written suggestions, not hitherto published :—‘Dr. Fenner has protested against the use of the term ‘Rift Valley’ for the complex area, part graben, part horst, including the two gulfs and the surrounding land masses. J] think that he is right on the ground that this area differs from the quite typical rift valley, such as that of Africa, etc. But one cannot expect such regularity of fracturing in a region having such complex structure as one would expect in a region with thick sub-horizontal sediments and massive lava flows affected by trough faulting. We do not yet know whether the phenomena of rift valleys are produced by normal or overthrust faulting— whether by the gravitative sinking of a wedge after relief of tensional stress by 5 faulting, or by adjustment to compressive stresses. In the first case the faults converge downwards, and in the latter they diverge. In the case of the Mount Lofty-Flinders horst it is difficult to conceive an origin by compression, despite the massive foreland to the westward. Probably the ancient sediments were folded against this foreland in the Palaeozoic Era, but the rise of the Mount Lofty- Flinders horst has been relatively recent. We know that the Mesozoic sediments at the northern end of the Flinders Range have been affected by the earth move- ments, even if there is an indication in Central Australia that the great depression of Lake Eyre began to take form in Permo-Carboniferous time. The origin of the twist in the southern end of the great lineal horst might indicate a com- pressive stress induced by the northward movement of an earth block now foundered. But if this were so there is no sign of a northern foreland in the Lake Eyre region. Were there such a resistant block we might be tempted to compare the structure of the region under discussion, in a broad way, with the middle Rhine Valley, between the Vosges and the Schwartzwald, where it has been sug- gested by Weber that the graben, like others, owes its existence to compressive stress parallel to its length, with the consequent production of tension normal to the compression. But the northern end of the Mount Lofty-Flinders horst faces a structural depression, and if we take Kangaroo Island as its southern terminal, we must admit that it faces another depression in the Jeffrey Deep. It is notice- able that part of the western foreland itselfi—the foundation of Yorke Peninsula— became involved in the faulting, a fact which seems to indicate that the stresses which produced fractures were not so wholly controlled by geological formations as might appear from the contrasted features on the opposite sides of the Torrens Sunkland farther north.” Professor Gregory, to whom we are indebted for the conception and defini- tion of rift valleys, himself so named this South Australian feature. But it is clear from the maps accompanying his account (p. 26, loc. cit.), that Professor Gregory was not then in possession of full information regarding the detailed position of the fault lines and the consequent outlines of the relatively lifted and sunken blocks. The northern and southern “horns” of the cusps, shown in fig. 2 D, are shown in Gregory’s maps as relics of “ancient east-west mountain ranges,” and the sunken area itself is drawn as almost parallel-sided, which is not a true representa- tion of the facts as we now know them. Special consideration has been given to recent literature regarding the mechanics and the terminology of such sunken areas. De Martonne (“Traite de Geographie Physique,” tome second, Paris, 1926) refers to clongated blocks of land that had been sunken, with relatively raised blocks on either side, as “ditches”—‘fossés tectoniques.” German physiographers use the word “graben” (after Suess) for narrow, relatively-depressed blocks, and “senkungsfelder” for larger and more irregular sunken areas. American physio- graphers (¢.g., Fenneman, A.A.A.G., vol. xviii, p. 348) use the term “moat,” thus: “The basin of Lake Tahoe is in a moat, that is, on a depressed fault-block between mountains on the west and east.” In all these terms—rift, graben, moat, ditch, fossé—and indeed in the word “valley” itself, there is a definite suggestion of parallelism of the sides and of an elongate character in general. Professor Gregory, who originated the term “rift valley” and applied it to the classic examples of the Dead Sea and the East African tectonic moats, empha- sises the parallelism of the boundary faults (“Ihe Rift Valleys and Geology of East Africa,” J. W. Gregory, London, 1921, chap. xxxli.). On page 18 of that work Gregory writes: “For this type of valley I suggested the name of Rift Valley, using the term ‘rift’ in the sense of a relatively narrow space due to subsidence between parallel fractures.” Howchin (Geography of South Australia, Adelaide, A.

A., Chief Place-names; B., Relief; C., Geology; D., Major Structural Features. ? 1918, p. 27) speaks of: “the sinking of a strip of country, forming a rift valley. . . .” Bailey Willis (Bulletin of the Geological Society of America, vol. xxxix., 1928, p. 493), in his definitions, gives: “Rift Valley: Valley pro- duced by subsidences of a strip bounded by two parallel rifts’—a “rift” being a “normal fault with gravitational displacement.” (See also “Geologic Structures,” Bailey Willis, New York, 1923, pp. 75-82.) Enough has been quoted to show that the authorities on these matters agree that some measure of elongation and of parallelism of the boundary faults are essentials in the structure of a rift valley, Neither of these features is present in the two cases under discussion. The Torrens depression is shaped like a laterally-compressed capital D, while the Spencer-Vincent depression is shaped like a broadly expanded D (see fig. 2). The writer is of opinion that the name of such an important structural feature is of distinct importance. In giving addresses on these matters to teachers, laymen, and to other students, he has experienced difficulty in readily conveying to his hearers a proper conception of the structural character of this area by the use of the terms “The Great Valley of South Australia” or the “Rift Valley.” He has already (lot cit.) suggested that these unhelpful and incorrect terms be discon- tinued, and he here repeats and emphasises the point. The sunken areas are better described as senkungsfelder, or, to adopt the anglicised form suggested to the writer by Professor E, W. Skeats, they might be called Sunklands: (a) the Torrens Sunkland, and (b) the Spencer-Vincent Sunkland, as set out in fig. 2 D, (c) The Chief Boundary Iaults—The dominant features of the Gulf and Torrens areas are set out in fig. 2, This figure includes four sketch maps entitled A,B, C, and D. A. gives the names of the chief features involved. B. indicates the comparative relief, the simplest description being that the shaded areas are hills and highlands, and the unshaded areas are plains. C. shows the geological formations in a broad way, all the Palaeozoic and older areas being shaded, and the Triassic and younger areas (mostly Tertiary and Recent) being unshaded. It will be noted how closely this geological division coincides with the physio- graphic facts. In D. the chief structural features, as interpreted by the writer, are clearly set out. Where a fault is indicated in the figure by a heavy broken line, there may be really a series of more or less parallel faults, extending both upwards into the highlands and downwards into the sunklands. Physiographic evidence of such step faults is available to all who journey along the adjoining plains on the eastern or western sides of either the Mount Lotty or the Flinders Ranges. In many cases, particularly in the Flinders Ranges and in the eastern Mount Lofty Ranges, these stepped blocks arc almost diagrammatic in appearance ; similar features in the fault scarp facing Adelaide have been described and figured by the writer (loc. cit., figs. 5, 6, 7). The stepped blocks of the Mount Lofty Ranges are best seen in an evening view from Outer Harbour or St. Kilda. Similar stepped faults have been mapped by R. L. Jack on the Lincoln Fault, Hundred of Randell (Bull. No, 3, S.A. Mines Dept.). To the eastward of the main are-shaped horsts are two uplifted areas that branch away tangentially to the north-east; that on the north is the high and rugged “Yudnamutana Spur,’ and that further south is the lower, broader, and more maturely eroded “Olary Spur.” Both of these features are much more than “spurs,” but this term is left unchanged for the present. Evidence collected by Mr. R. L, Jack indicates that the low Olary ridge is not bounded by fault lines. In emphasising the peculiar and regular arc-shaped character of the Mount Lofty and Flinders faults, the following facts, quoted by Professor W. M. Davis (vide “Geographical Review,” October, 1927, p. 669) are of special interest :— At the 1926 Spring meeting of the California Rift Club, Davis spoke “with 8 especial regard to the contrast between rifts (faults) of the San Andreas type, on which movements with a large horizontal component seem to predominate, and rifts of the Wasatch type, on which movements with a large vertical component prevail. In examples of the first type the path or trace of the rift is nearly recti- linear, and there is no strong or persistent difference of elevation on its two sides. In examples of the second type the trace of the rift departs from a straight line in many concave bights from one to five or ten miles in curved length, between somewhat pronounced cusps which point from the side of elevation to the side of depression; and the side of elevation is occupied by a more or less dissected moun- tain range, while the side of depression is occupied by an aggraded plain of moun- tain-supplied detritus,” This interesting description corresponds very closely on the South Australian structures with which we are dealing. The boundary faults of the Mount Lofty and Flinders ranges horsts, for instance, appear to be of the Wasatch type. They have a large vertical component, as evidenced by the fact that within a range of twelve miles normal to the fault face adjoining the city of Adelaide there is, within the limit of some six-stepped blocks, a differential displacement of from 4,000 to 5,000 feet. ‘The highest point of the Mount Lofty block stands at 2,330 feet above sea level, and in the Croydon bore, 12 miles distant, the surface of the same rocks has been faulted down to a depth of at least 2,260 feet. Regarding the trace of such faults, their graceful curves, on a large scale, are their most notable feature. Such curves are certainly greater in size than those described by Professor Davis, but they otherwise fit his description. ‘Ihe question arises whether the straight boundary faults of the western parts of the sunken areas (the Lincoln and Torrens faults) are of the San Andreas type. They are cer- tainly almost rectilinear, as delimited by both the geological and physiographic evi- dence ; and the difference of elevation, though in many cases marked and regular, may perhaps be described as “neither strong nor persistent.” Certainly these western faults have characters which distinguish them from those of the eastern boundaries of the sunklands (fig. 2). If this analysis is correct, we should expect the Lincoln and Torrens faults to have large horizontal components in their move- ments. On this point no evidence is at present available. (d) Festoon or Garland Structures—There is a further point of interest regarding these arc-shaped horsts. Among the outstanding characteristics of circum-Pacific structural features are the arc-shaped chains of uplifted land that appear on our maps as mountain ranges or island groups, according to their rela- tion to sea level. These have been aptly called “Festoons” by Suess, Gregory, and others, and “Garlands” by Ilobbs (“Les Guirlandes Insulaires, ete.,” W.H. Hobbs, Annales de Geographie, tome xxxi., 1922, pp, 485-495). Such island festoons are characteristically convex outwards towards the great Pacific basin. They are regarded as rising anticlines, Suess holding that the dis- placement comes from the concave (landward) side and the resistance from the ocean; while Hobbs conceives the movement to come from the ocean (convex) side, with the “mdle de résistance” on the continental side. While it is clear that these great differentially uplifted arcs of the Mount Lofty and Flinders ranges are structures of a different character from the island festoons, there is yet something that is common to the two sets of structures. The writer has already pointed out (loc. cit., p. 199) that the Great East-Austra- lian Highland Horst, reaching from Cape York to Southern Tasmania, is some- what of this shape, and that many similar cases occur, such as the block-faulted Victorian Grampians, where the mountains consist of differentially uplifted arcs, again convex towards the east (the Pacific). (e) The Dynamics of the Movements —tIn his first considerations of the dynamics of the movements concerned the writer accepted the common view that 9 block mountains such as those of the Mount Lofty and Flinders ranges had to do with normal faults and were associated with tensile stresses. In a detailed field in- vestigation of these ranges as landscape features, there is much to suggest that the movements have been “thrust” movements, that compression and not tension has been the dominating factor. These impressions are of no positive value as evidence, but in areas as naked in structure as the Flinders Ranges, and where so little mapping has been done or sections prepared, such impressions assume a somewhat higher degree of importance. The dynamics of “Rift” valleys has lately come in for much discussion. The fundamental principles touch on a problem of long standing and of great and almost insoluble difficulty. Are these movements due to crustal tension or to crustal compression? The idea of a “Rift Valley” as expounded by Gregory carries with it the existence of “normal” faults, of beds that occupy a total linear extension (normal to the faults) greater than before the faulting, and thus of a tensile (tearing apart) stress of the rocks of the crust—the subsidence of the “Keystone” of an anticlinal arch. The alternative theory now put forward, and supported by considerable evidence, is that some of the so-called rift valleys are due to compression and not to tension. It is argued that the side blocks have becn pushed towards one another, and that along the fault lines bounding the central block the lateral blocks have risen and ridden along thrust planes over the wide base of the central block. The name of “Ramp Valley” has been suggested to distinguish such valleys as being due to compression. The classic argument for the “Ramp Valley” theory is Bailey Willis’s paper on “The Dead Sea Problem,” published by the Geological Society of America (loc. cit.). The paper contains several converging lines of evidence towards the theory that the chief factor in the formation of these major tectonic features is compression and not tension. The Spencer-V incent Sunkland is not a parallel case; there are many differences, but there are some similarities. We have no evidence to show whether the bounding faults of the local ranges and depressions are normal or thrust faults. Another exponent of the compression theory is E. J. Wayland, of Uganda (‘“‘Nature,” March, 1924, p. 388), who has worked on the “Rift Valleys” of eastern and north-eastern Africa. Wayland admits the existence of some normal faults along the boundaries of the sunken areas, but considers that these are consequent upon subsidence, and that they obscure the original structures due to crustal com- pression. In the “Mining Magazine,” April, 1929, there is a reference to a paper by Ernest Parsons (Trans. Geol. Soc. S. Af., vol. xxxi., 1928), wherein it is again argued that the rift-making forces are compressional rather than tensional; that they are such forces as produce folding elsewhere, but in an area of exceptional stability produce fracturing with reversed faulting. This compression theory is a suggestive one, and in the special case of the Gulf Region of South Australia it must also include the formation of the Mount Lofty and Flinders ranges; it is possible that this theory may yet provide an explanation for the peculiar fact that the “festoons” of highlands in Australia are so like, yet so distinct in character from those “compression festoons” of other areas where it is reasonable to assume a lower crustal stability than we have in the Australian region. (f) The Age of the Fault Block Movements.—The age of the last great orogenic uplift in Australia, the “Kosciusko epoch,” is generally considered to be early Pleistocene. But there is evidence also of movements of the same kind in the same localities at earlier dates, perhaps even as far back as the close of the Cretaceous, and it may be also that definite movements continued up to the late Pleistocene and Recent. 10 The writer has discussed this question in detail in his paper on the “Physio- graphy of the Werribee River Area, Victoria” (Proc. Roy. Soc. Vic., vol. xxxi., 1918,), where the chief Australian authorities and references up to that date are quoted. ‘The conclusion reached was that the general peneplanation of Australia was completed in lower Miocene time, and that the major faulting and differential uplift took place from late Pliocene onwards. In the twelve or more years since that paper was written the writer has had further opportunities of studying the block mountains, sunklands, and the sub- sequent erosional valleys in the other States of the Commonwealth, and of further studying the arguments put forward and the conclusions reached regarding the age of similar horst and graben movements in other parts of the world, where there might reasonably be expected to be some amount of sccular correlation, The conclusion now reached is in the direction of giving a wider range in time to these block-faulting movements. Granting that the Great Peneplanation of Australia was a pre-Miocene phenomenon, some of the orogenic uplift may have been contemporaneous with the emergence of the mid-Miocene areas from the sea, and the movements possibly continued persistently, with periods of extra stress, right through the upper Miocene, and the Pliocene (which was a time of great volcanic activity), with a more intense phase in the eatly Pleistocene, The Pliocene phases might be associated with the formation of the horsts and graben, and that of the Pleistocene with the later rapid uplift of the western blocks of the Mount Lofty Ranges, leading to the formation of the Torrens, Sturt, and Onkaparinga gorges, and associated with all those younger and more obvious evidences of late block faulting that are found in the orogenic areas of Australia. Further, there is evidence in the Adelaide area, both at Hallett’s Cove and at the southern end of the Para fault scarp (in Adelaide), of differential movements along fault lines in late Pleistocene to Recent time.

The Gulf and Torrens areas of South Australia represent major tectonic features that form the southern portion of what is suggested to be a great broken zone extending northwards across Australia, and separating the more stable western from the less stable eastern portion. ii, The chief elements of the tectonic features concerned are as sct out in fig, 2, iii, The names “Rift Valley” and “Great Valley of South Australia” are not considered satisfactory, and it is suggested that they be replaced by the terms: “Spencer-Vincent Sunkland” and the “Torrens Sunk- land,” wide fig. 2, iv. The dynamics of these features are unknown; they may be due either to tension or to compression. v. The differential block movements of uplift and depression are assumed to have commenced in the upper Miocene with considerable emphasis in the Pliocene; an extensive and important movement; specially con- centrated along the western margin of the horsts, at the opening of the Pleistocene (Kosciusko epoch), with final lesser movements in the late Pleistocene to Recent. This question is further discussed in Section V (a), where the possibility of a second (? Upper Pliocene) period of planation is suggested. IV.—PHYSIOGRAPHY AND CLIMATE, (a) Exoreism, Endoreism, and Areism—In the early days of physiographic study most workers concentrated on what was called “sub-aerial erosion,” By this term was meant, in general, the normal work of erosion by rivers and their tributaries in areas of practically permanent flow, During the two last decades 11 there has been some concentration on the physiographic cycle in arid and semi- arid lands, and it has been shown to what a high degree the agents of erosion and the products of erosive action differ according to the prevailing climatic conditions. Among those who have assisted in drawing up standards for the assessment of the physiographic processes in arid lands, the work of Professor de Martonne, of the University of Paris, is notable. A recent paper by this authortiy has proved to be of special assistance in considering the problems presented by the inter- actions of physiography and climate in South Australia. (“Regions of Interior- Basin Drainage,’ Emm. de Martonne, Geographical Review, July, 1927, pp. 397-414). De Martonne has shown the very important distinction that exists between areas where the precipitation is sufficient to cause the development of a drainage system that leads to the sea (exorcic), compared with an area where the precipita- tion is lower, or the evaporation greater, or the absorption more marked, or where some or all of these factors may operate together so that the streams developed never have sufficient power to find a way to the sea, and either disappear in an alluvial basin or end in centres of internal (endoreic) drainage. In still other areas, where the conditions are cven more arid, there is no run-off at all, and no stream courses are developed; such areas are called areic regions. The three terms tsed, with their definitions, are as follows; each of them being derived from Greek words :— Exoreism, meaning through-flowing, or drainage to the ocean. Endoreism, inward-flowing, or interior basin drainage; and Areism, which indicates regions with no flow, where there is no run-off at all. To these the writer proposes to add a fourth and minor type: “Cryptoreism,” a form of exoreism, signifying hidden (underground) flow, as in the south- eastern region of South Australia. “The deserts,” writes de Martonne, “are par excellence the regions of interior- basin drainage or endoreism, but they present a particular case where run-off is nil, and for which the term areism is proposed.” In fig, 3 the various factors are set out on six small maps as follows :— A.—In this map are shown the various place-names, so that descriptions of the State may be followed by those not familiar with local topography. B.—Shows the general relief, and is taken from maps prepared by Dr. L. Keith Ward, Director of Mines, South Australia. The scale of the series of sketch maps is shown in this figure. C.—Shows the mean annual rainfall (isohyets) of the State, kindly supplied by Mr. E. Bromley, of the Commonwealth Meteorological Bureau, and is from the latest records. This map includes three parallels of lati- tude for comparative purposes. D.—Gives the lines of mean annual evaporation. These are in the main estimates, but have been checked up by records which show that the evaporation at Adelaide is 544 inches per annum from a free water suriace, and at Alice Springs (across the northern border in Central Australia) the evaporation is 943 inches per annum. E.—Shows the mean annual temperature. Between the isotherm of 60° and that of 65° the influence of the Mount Lofty Ranges brings in an “oasis” of coolness where the temperatures run from 55° to 60° (all these temperatures are Fahrenheit). On this map is also indicated the chief artesian and sub-artesian basins of the State. 12 —— a—= p——J ——F AIT: ——=———————— ' MUSGRAVE RANGES 1 NORTH-WEST a; Sey he 1 we 4 PLAINS oy LAKE -—- HR 2000' to 4000. = =" ERY 1900! to 2000' Ny *, EZ] s00'To 1009" fe [[] o'te 500* re Below Sea Level-te l00Fa.

Six sketch maps presenting the facts regarding the commoner place- names, relief, rainfall, evaporation, and temperature of South Australia, with a division of the State into areic, endoreic, and exoreic areas. 13 F.—This figure, based upon the information given in the preceding figures, shows the position and extent of the areas of arcism, endoreism, and exoreism in South Australia. A fourth type of drainage is indicated by broken lines in the extreme South-East where, although the rainfall is sufficient to establish exoreism under normal geological conditions, there are no flowing surface streams. According to de Martonne’s definitions, areic areas are those where there is no run-off. Through such an area, a river, such as the Nile or the Murray, may run, but its waters are derived from distant sources, and the area passed through is still areic, despite the presence of the river. In a similar way many of the rivers of the Lake Eyre Basin receive no additional water in the lower parts of their courses across the wide central plains. Such regions, though occasionally crossed by run-off from neighbouring highlands, are themselves without run-off ; that is, they are areas of areism. Taking due advantage of latest and most detailed information available, the writer finds that his map of South Australia very closely coincides with the details for South Australia as published in the article above quoted. On the whole, de Martonne was perhaps a little more generous than the circumstances permit. It will be seen from F, fig. 3, that the greater part of South Australia is areic— particularly the area north of lat. 32° S., and also the greater part of Eyre Peninsula and Yorke Peninsula. The “South-East” presents a peculiar case. North and east from a low scarp that runs north-west from Naracoorte, there is a distinct run-off, with definite streams flowing towards the west (see fig. 5). Beyond this scarp, to the west, where there is sufficient rainfall to have developed a through system of drainage (exoreism), the following antagonistic factors exist, The peculiar arrangement of old dune ridges parallel with the coast and normal to the natural flow of surface water, the nature of the country (level-bedded porous Miocene limestone with incipient karst topography), and the extent of the underground drainage, have prevented the development of exoreism, although in winter time (the wet season), the water travels over the surface in wide-spreading sheets. A high proportion of water also travels underground and reaches the sea by means of coastal springs. It would be wrong to class this region as areic, or even endoreic. It is really a type of exoreism, but represents something different which de Mar- tonne has not defined. The writer suggests that this type of drainage be termed “cryptoreic” (hidden drainage), to be applied only where the index of aridity is above, say, 30, with no surface streams developed. The areas referred to are shaded in fig. 3 F by broken horizontal lines. Endoreism-—The areas of endoreism are shown in F, fig. 3, and by com- parison with the rainfall, temperature, evaporation, and relief of the accompany- ing sketch maps it will be realized why they are so closely limited to the highland areas, In these highlands, such as the Flinders and Musgrave ranges, the develop- ment of drainage patterns of normal stream-cut type is marked, and points back to a Pleistocenc pluvial period or series of periods that possibly corresponded with the glaciation of Kosciusko and Tasmania and with the suite of large and varied animal life (now extinct) of the interior. These stream courses will be dealt with in some detail in a later section. In many cases the water from the highlands continues across wide stretches of areic plains in times of exceptional rains; in 1930 wide sheets of water lay for upwards of two weeks on the usually arid Nullarbor Plains. Exoreism.—tThis type of drainage, where the streams flow through to the sea, though normal in those countries of the world where the physiographic features have been most closely studied, is not normal in South Australia. The exoreic 14 areas are shown in fig. 3, with horizontal shading, and they include only the Mount Lofty Ranges and portion of the South Flinders. Even in the parts mentioned, a high proportion of the water which flows from the Mount Lofty Ranges is lost where such streams as the Gawler, the Light, the Broughton, and the Burra Creek, cross wide alluvial plains. (b) The “Index of Aridity”’—De Martonne has given us a valuable method of estimating climate, by what is called the index of aridity. This is independent of the use of the indefinite term “desert,” and is calculated on the following formula :— P Ar = st * T+ 10 Ar represents the “Index of Aridity,” P is the mean annual rainfall in milli- meters, and T is the mean annual temperature in degrees centigrade. Un- fortunately, the formula so acts that the less arid the country the higher is the index of aridity. Applying this index to the whole world, it is shown that areas with a high degree of aridity are also areas of endoreism, and particularly of areism. In other words, the moist regions of the world are regions of through drainage (exoreism), and the semi-arid and desert regions of the world are regions of endoreism and areism. The index of aridity in the Southern Hemisphere is lowest (driest) about latitude 30°. This applies to the other southern continents as it does to Australia. The following are the indices of aridity for characteristic regions of South Australia -— Mean Annual Mean Annual Index Temperature. Precipitation. of Aridity. Central Lake Eyre Basin .. .. 70°F 5” 4:1 Northern margin of wheat lands (10” isohyet) .. oA .. 64°F 10” 9-1 Adelaide (metropolitan area .. 63°F 21” 19°6 Southern ends of Peninsulas &, 60° F 28” 27°8 The highest index shown in the State is about 32, which corresponds with the generalization that exoreism is at its maximum for valucs above 35. The northern margin of our settled cultivated areas has an index of 9+1, which is within de Martonne’s limit of areism (desert). The statements put forward in the paper referred to thus assist in a more satisfactory description of our State, and a more complete correlation of the physiographic with the climatic conditions. The conditions in South Australia also generally agree with the statement of E.G. R. Taylor (“Oceans and Rivers,” p. 26) that “In cool temperate climates the run-off approaches zero when the rainfall is only ten inches, while in sub- tropical regions 20 inches of rain, and in Torrid regions 40 inches of rain, is necessary to ensure flowing rivers.” It is unfortunately true, as stated by de Martonne, that while Asia, Africa, and Australia are the three continents with the least perfect drainage, with the greatest area of internal drainage, and with the most massive structure, Australia among all the continents holds the record for endoreism, namely, 64°% of the total area, of which latter portion two-thirds is areic. 15 V—THE SOUTH AUSTRALIAN HIGHLANDS. (a) The Mount Lofty Ranges—The features dealt with in this and the following sections have frequently been described in a general way. It is here proposed to deal with them purely from the point of view of the tectonic move- ments that have affected them, the rocks of which they are composed, and the erosion which they have subsequently undergone. The broad outlines of the structure of the Mount Lofty Ranges have been described in Section I. ‘Chey have also been dealt with, in some detail, elsewhere by the writer (Trans. Roy. Soc, S, Austr., vol. li, 1927, with several figures). In the popular local acceptation of the term, the Mount Lofty Ranges consist only of that abruptly-uplifted highland arc of ancient highly-resistant Cambrian and Pre-Cambrian rocks (quartzites, tillites, slates, limestones, schists, gneisses, and granites) that runs from Cape Jervis to the Torrens Valley, or perhaps north- wards to the valley of the South Para River. Here there appears to be a striking radial (east-west) fault zone, and the ranges thence northward are of a much lower and physiographically older type. Genetically, however, and from the structural point of view, the Mount Lofty Ranges may be held to include the whole of the highland arc northward up to the neighbourhood of Georgetown, as well as its continuation in Kangaroo Island to the south-west (see fig. 2D.). This highland area is severcly block-faulted, in curving lines, parallel with the general outline of the horst, the blocks mainly dipping their old peneplain surfaces to the east and the scarp to the west. Regarded from the west, this uplifted arc reaches its maximum elevation at Mount Lofty itself, directly east of the city of Adelaide, thence sloping downwards both to the south and to the north. Radial faults also occur, normal to the margins of the horst, and it is likely that a con- siderable number of the transverse valleys of the ranges mask radial faults; this is apparently so in many of the “gullies” facing Adelaide. Several of the longi- tudinal valleys are in part tectonic, but the main lines of drainage are apparently antecedent, with tributaries strongly influenced both by later block-faulting and underlying rock structures. The greater part, perhaps the whole, of the horst of the Mount Lofty Ranges has been stripped of a covering of level-bedded, easily-eroded, Tertiary (marine Miocene) sediments. It is generally agreed that differential uplift (block- faulting) and contemporaneous and subsequent erosion have formed the features as we know them to-day. Only one peneplain (pre-Miocene) and only one great uplift (dominantly Pleistocene, the “Kosciusko Epoch”) have usually been considered. This hypothesis, however, does not explain all the peculiarities of certain critical areas, such as the Torrens Valley on the one hand, and the coastal strip that runs from O’Halloran Hill to Myponga on the other. Some of the existing structures of these areas could perhaps be better explained by assuming two dominant stages of block-faulting, with two periods of peneplanation, the later planation being partly carried out in the softer Tertiary “overmass.” This pos- sibility was suggested to the writer by Professor Douglas W. Johnson, of Columbia University, New York, while travelling over the area in question. The theory has not been fully investigated, but a score or more visits have been paid to critical localities, and there is sufficient general support available to justify some elabora- tion of the suggestion. In order to give definiteness to this modified hypothesis regarding the struc- ture of the Mount Lofty Ranges, and to better permit of critical consideration thereof, fig. 4 has been drawn to illustrate the suggested succession of events. The sections in the figure are purely diagrammatic, and are lettered A, B, C, D, E; the hypothetical blocks are numbered 1, 2, 3, 4, 5. LATER ALLUVIUM. OLDER ALLUVIUM, MIOCENE LIMESTONES. CAMBRO- CAMBRIAN COMPLEX. PRE Fig. 4. A series of sections drawn to illustrate the theory that at least two periods of Tertiary peneplanation are involved in the production of the f the Mount Lofty Ranges, as described in the present topography o context, 17 In section A we have the prevailing highly-resistant Cambrian and Pre- Cambrian complex (quartzites, slates, tillite, gneisses, schists, and intrusive rocks), which was planed down to a remarkably widespread level surface in pre-Miocene times (cf. Davis’s “Geographical Essays,” Boston, 1909, chapters xvii. and xviii.). There were also some softer Permian tillites and Mesozoic sediments. but these do not affect the present discussion, The peneplain, which must have extended well to the south of the present limits of the State, became covered by the sea in Miocene time, when a series of marine limestones and clays were deposited, indicated as the horizontal overmass in section A, In section B is indicated a phase of block-faulting, tilting, and differential uplift that may have taken place in the upper Miocene or lower Pliocene: this figure shows the “end product” of the tectonic phase, that is, as the blocks would have appeared at the conclusion of their displacement had there been no con- temporaneous erosion. In section C we have a second peneplain, the product of the contemporaneous erosion of the preceding uplift, plus a sustained period of planation extending to, say, the beginning of the Pleistocene. In this stage there may have been produced the mature landscapes of the upper Torrens (Mount Pleasant), etc, According to their tilting and relative uplift, the materials of the five blocks have been pre- served to varying extents: Block 1, wholly preserved and covered by alluvium; block 2, the pre-Miocene peneplain stripped of its overmass and re-exposed (exhumed) ; blocks 3 and 4, the new peneplain truncating the Pre-Cambrian and the Miocene alike; block 5, the new peneplain formed on one portion of the block, while over the eastern half the easily-eroded overmass has been stripped off by erosion, exposing the older peneplain ; thus two peneplains of different ages adjoin each other. In section D is suggested a period of, say, Pleistocene uplift (the “Kosciusko Epoch’), mainly along the original fault lines; this section shows the final product of the uplift and tilting as it would have appeared had there been no contemporan- eous erosion, In section E we have: Block 1, the whole of the three series of rocks pre- served, depressed, and covered by recent alluvium from adjoining higher blocks (Adelaide Plains) ; block 2, the first (pre-~Miocene) peneplain exhumed, uplifted, and subjected to a fresh cycle of erosion (? Mount Osmond Golf Links) ; blocks 3 and 4, erosion of western scarp face with deposition of “fault-apron” alluvial on adjoining lower block (Burnside, Sellick’s Hill, etc.) ; portion of second peneplain preserved (? O'Halloran Hill) ; portion of first peneplain exhumed by erosion of Miocene limestones (? McLaren Vale) ; remnant of Miocene limestones, alluvial- covered, towards the adjoining scarp (?Noarlunga and Port Willunga); block 5, youthful (Recent) valleys in both the first (pre-Miocene) and the second (? late Pliocene to early Pleistocene) peneplains. In section E the surface of the first (older) peneplain is shown by a thick black line, the surface of the second (younger) peneplain by a shaded line, and the remainder of the surface (thin line) is that of the third (present cycle of erosion that is involved in the period and area dealt with. The preceding paragraphs, with the accompanying sections (fig. 4), present in bricf the essential features of a modified hypothesis regarding the physiographic history of the Adelaide and Mount Lofty area. Reference was made in a previous section to relatively late movements along fault lines in the Adelaide district. There are two or three lines of evidence that are of special interest :-—Along the western boundary of the southern portion of the city of Adelaide, from the Newmarket Hotel to Keswick Railway Bridge, the incoherent Pleistocene and later gravels, silts, ctc., have been faulted. The line of the fault scarp is still to be seen (notwithstanding roads, cuttings, and other 18 artificial earthworks of various kinds), and despite long-continued erosion it per- sists as a distinct break in elevation—the most southerly portion of the Para Scearp. This suggests Recent movement along the Para Fault. The friable, dissected, horizontal, ferruginous beds of (?) Pleistocene age that remain against the main Mount Lofty Scarp on the south side of the Anstey’s Hill road provide supporting evidence of this Recent uplift, Also, at Hallett’s Cove, a triangular patch of very readily-croded rocks (Permo-Carboniferous tillite, a thin band of ? Lower Plio- cene marine limestone, and thick overlying ? Pleistocene mottled clays) have been: (a) preserved by down-faulting, and (b) uplifted and dissected by marine and sub-aerial erosion; this also suggests very late fault movements, well worthy of closer investigation. Nothing further need be added, except to affirm that the mature landscapes of the upper Torrens, upper Onkaparinga, and other streams heading towards the Mount Pleasant area are difficult of explanation, unless we assume a long period of sub-aerial planation following the first uplift, some exhumation of the pre-Miocene surface, and some later tectonic influences, followed by the present cycle of erosion, The two or three western blocks that are truncated by the Torrens Gorge must have risen later, and their topography, antecedent, super- imposed (Torrens, Para, etc.), and consequent with headward erosion (Morialta, Waterfall Gully, etc.), is in a youthful phase, The ranges from Gawler northward to Gladstone are of a different character, and their story remains to be written. On some blocks there is evidence of late- youthful topography, but for the most part this productive region represents a “matureland” (Willis) of low hills and broad valleys, characteristically developed in the basin of the River Light. Further north, the Mount Lofty Ranges widen and gently curve onwards into the Flinders Ranges (see fig. 2). To the north-east a broad, low “spur,” which has been called the Olary Spur, runs away towards and through Broken Hill, This is, in fact, a broad uplifted plateau (1,000 feet to 2,000 feet), and it has a mature topography, while the structure along its boundaries indicates warping rather than faulting. As Howchin has pointed out, the stream courses are in many cases most uncertain and anomalous, and may change direction from one flood-time to another. The proximal portion of this “spur,” which is situated eastward of the area where the Mount Lofty Ranges merge into the Flinders Ranges, is really a maturely-developed, up-warped plateau, over 1,000 feet above sea level, with occasional higher ridges. A characteristic feature of this area, and indeed of many other portions of the State, consists of wide plains, deeply filled with alluvial. Sometimes, as in the upper portions of the Broughton and Light Rivers, the local streams are drained to the sca (exoreic). In other cases, of which Pekina Creek is an example, streams run into deep alluvial basins, and are lost. The statement that “Even the weariest river winds somewhere safe to sea,” was written by a poet of a moister land than ours, Most South Australian rivers, however weary, do not reach the sea, but find their resting-places in wide and deep alluvial-Alled basins—basins that have been filled up by the long-continued silting action of the rivers that still periodically flow into them, aided by deposits of wind- borne dust. These widespread alluvial-filled basins are among the most significant features of the physiography of South Australia. They occur as the so-called central “lakes” —Torrens, Eyre, Frome, etc. They are the foundations of many of the fertile wheat plains of the northern areas, and will probably be found to have played an important part of the story of the physiographic development of the lower Murray River itself. 19 On the Peterborough Plateau, and along the Olary Spur, which is only partly within the area of 10-inch rainfall, we get marked evidences of arid and semi- arid physiography, namely :— (a) Sustained wind-erosion with occasional rapid water-erosion. (b) Stream courses of the wady type, sometimes erratic in direction, steeply gullied in their upper portions, ending in broad alluvial fans or wide alluvial basins, (b) The Flinders Ranges—Broadly speaking, the Flinders Ranges may be regarded as a repetition of the Mount Lofty Ranges. There is a similar horst structure, abruptly ending along fault scarps on east and west, a similar arc- shaped curve in the plan of the ranges, and a similar, but much more dominant and impressive north-easterly spur. (See fig. 2.) There is even a break between the cusp of the Willouran Ranges and the main range analogous to the break at Backstairs Passage in the south. The rock types embrace the same series of ancient and highly-resistant rocks, and the structures are fairly similar, though the block-faulted and tilted masses of the Flinders Ranges show also definite synclinal and anticlinal structures, as at Wilpena and Blinman (Howchin). In spite of these similarities, the Flinders Ranges, as landscape features, are utterly unlike the Mount Lofty Ranges. One could not conceive, a priori, that there would be so striking a difference between the landscapes of the two ranges, which have structures so similar and rock types so alike. This difference, it would appear, is largely due to the fact that wind erosion is today a more important factor in the sculpture of the Flinders Ranges than it is in the moister Mount Lofty Ranges. Where the Flinders Ranges are abrupt, rugged, pinnacled, and (in places) naked of soil and vegetation, the Mount Lofty Ranges are softened and rounded in outline, and clothed with soil and vegetation. The wind erosion phase of the Flinders Ranges is, nevertheless, imposed upon a drainage network formed by water. Water is still doing its work, but in the pluvial period that is believed to have been experienced here in lower Pleistocene time (Gregory, David, Howchin, etc.), the patterns of the ranges were decided upon, and the influence therein of rock structures, and to a lesser extent of rock types, is marked. The full story has not yet been worked out in detail, owing to the almost complete absence of mapping in these areas, but a study of exceptional interest here awaits some future worker. The Yudnamutana Spur contains some of the wildest and boldest parts of the ranges. The strike of the Cambrian and Pre-Cambrian rocks, instead of running parallel with the range, as is usually the case, is most varied and unexpected. Dr. Ward and Mr. R. Lockhart Jack have plotted sufficient data to show that the strike and dip here are most confused, bearing witness to exceptional torsion, differential movement, and general disturbance. The same writers have shown that this Cambrian and Pre-Cambrian horst continues onward underground to the north, plunging below the Cretaceous beds, as revealed by bores in the artesian basin of the north-east, (c) The Musgrave and Everard Ranges—These ranges are little known structurally. Mr, R. Lockhart Jack (Geological Survey, S.A. Bull., No. 5), con- siders that faulting plays a considerable part in their structure. Their general direction is east-west. In the Musgrave Ranges granitic cores and bosses play an important part in determining the structures, with schists and gneisses in the Everards, but there is a marginal “festoon” of residual hills to the south that is formed from Ordovician sediments. ‘The main granite masses are also slightly arc-shaped, concave to the north, The ranges are in general low and scattered, with wide alluvial-filled plains or plateaus between. The main Musgrave mass rises more mountainously, and is 20 crowned by the highest peak in the State, Mount Woodroffe, about 5,000 feet. The general valley pattern has been water-formed (see fig. 6), and some streams still run to the north, east, and south, from the main range, but are only occasion- ally called upon to function. In times of exceptional rain some of the run-off from the Musgraves reach the Lake Eyre Basin, via the Alberga. The chief erosive agent in so arid an area is the wind, aided by a wide range of daily temperature variation. Rugged, bare, rock faces, sand-blast features, sand accumulations, bare talus slopes—all bear witness to the consistent, never- ceasing eroding and transporting power of the wind. The hill shapes bear witness, as do the stream patterns, to their formation under normal conditions of moist sub-aerial erosion. Also, as is common in the mountain and hill physiography of deserts generally, the structural features, almost unmasked by soil or vegetation except for the characteristic “sand burial” around their bases, bear definite evi- dence of their tectonic or plutonic origin. (d) The Gawler and West Coast Ranges —The Gawler Ranges are formed by a series of ridges, with many wide valleys, that run in an irregular way along what might be regarded as the northern boundary of Eyre Peninsula. These ranges are quite different in structure from any other of the ranges herein described, due to their formation from igneous rocks (felspar porphyries) which are classed by Ward as dykes, sills, and flows of pre-Cambrian time. It is suggested that this relatively higher area is a westward continuation of the up-warp of the Peterborough plateau, emphasised by the greater relative erosional resistance of the porphyries, and that the same movements formed the relative depression to the north that is now the site of “Lake” Gairdner and other salt flats and “lagoons.” Howchin regards this range as one of a very ancient and important series of east-west mountains, but the Gawler Ranges are certainly quite distinct, structurally, from the Willouran Ranges and Kangaroo Island, with which they have sometimes been bracketed. If the Gawler Ranges were not formed in an up-warp during the later Tertiary, then we may regard them as a residual monadnock ridge from the pre-Miocene peneplanation, possibly due to differential resistance, rounded off by ages of arid-land erosion. (e) The “Tent-Hills” of the Interior —\n a broad belt of country extending northwards from Whyalla and Iron Knob to the northern boundary of the State, and roughly marginal in the north to the Great Artesian Basin, there is a series of flat-topped hills, locally known as “Tent Hills,” or “Table-top Hills.” Similar isolated hills occur elsewhere in the interior. The shape is striking, in that they are almost invariably flat-topped and steep-sided, with cliffs in the upper part of their outline and extensive screes below. lf all of these were, as some of them are, in level-bedded rocks of varying erosional resistance, we should have the typical mesas and buttes (“Zeugen,” Walther) of Central Asia, Western United States, and elsewhere. But this is not the case; a wide variety of rock types and structures is found in these tent-hills. The typical and well-known hill named Crown Point, approximately the geo- metrical centre of Australia (Ward), is of contorted Permo-Carboniferous glacial till; those in the neighbourhood of Port Augusta may be of steeply-folded Ordo- vician sediments; others are of horizontal Ordovician sediments, some are of still older rocks of varied structure; most of these features are formed in Cretaceous or Tertiary sediments. In spite of the wide variety of structures and of erosional resistance, the type of hill does not vary greatly. The capping material, according to Ward (Trans. Roy. Soc. S. Austr., vol. xlix., p. 76), is a silicified sandstone or conglomerate, an arid land feature, and this capping is largely independent of the nature of the underlying rocks. It appears to be undoubted that the level tops of the tent-hills are the relics of an uplifted peneplain, and that the intermediate plains and valleys that now Zl separate these remnants were laid down by running water, but widened and deepened during long ages of insolation and wind erosion, with the occasional work of thunderstorms and floods. In the latter-day usage of the word, the lower level area might perhaps be called a second peneplain. (f£) The Volcanic Hills of the South-East—The only volcanic hills of South Australia are found in the extreme south-eastern corner of the State, and are genetically associated with the great outburst of volcanic activity that occurred in central and western Victoria in the late Tertiary (? Pliocene to Recent), There are also some minor residual volcanic hills in Kangaroo Island. The South- Eastern group includes several smali centres of eruption: Mounts Gambier, Schank, Muirhead, Burr, McIntyre, Edward, The Bluff, etc, (see fig. 5). It is likely that Mounts Gambier and Schank were among the latest of these volcanic foci to be in operation, Mount Schank is a fine example of a symmetrical crater of tufaceous materials, partially collapsed. Mount Gambier consisted of three or more tufaceous cones, with subsequent large-scale collapse below the water-level of the sub-artesian basin that occurs here, forming a series of steep-sided and picturesque lakes. Several of the neighbouring volcanic hills, from The Bluff to Mount Muir- head, lie along a fault scarp, with which there may have been some genetic associa- tion ; the evidence at The Bluff suggests that the faulting was, in part, subsequent to the vulcanicity. VI—PLAINS AND PLATEAUS. The greater part of South Australia, as may be seen from fig. 3 B, consists of vast plains less than 500 feet in elevation, or of similar wide plains gently rising from 500 to 1,000 feet or more in elevation and consequently in places referred to as plateaus. Structurally, they require but brief description, though they vary greatly in mode of origin, (a) The North-western Plateau—This comprises the shaded area that occupies roughly the north-western quadrant of fig. 3B, excluding the Musgrave Ranges in the extreme north-west (also called the North-west Plains), These vast expanses are little known; parts of them are quite unknown. As far as our records show, they are an area of very ancient rocks, largely a crystalline complex, structurally stable, peneplaned by ages of sub-aerial erosion dominantly aeolian in the latest phases, of very low relief, and practically without watercourses. Along the eastern side, margining the Eyre and Torrens basins, there are some wide, sand-floored valleys, separated by the characteristic “tent-hills” already described. Elsewhere the surface is, for the most part, a series of monotonous parallel (N.W.-S.E.) stationary sand dunes, or rough gibber (stony) plains, varied with clay-pans, with here and there low granitic outcrops and accompanying rock-holes. (b) The Plains of the North-East.—These include the Lake Eyre and Lake Frome basins, superficially resembling, but in all other ways contrasting with, the North-west Plateau, For the most part this area is one of almost level-bedded Mesozoic rocks; these belong to the Great Artesian Basin of Australia, and the whole appears to be, structurally, a sagged or sunken area, level-bedded in the interior and more or less up-warped towards the margins, The surface has a reticulation of stream courses, described in a later section (see fig. 6). Apart from these streams, with their accompanying billabongs and lagoons, which are in places causing fairly rapid siltation along their banks, the area is one of drifting (bare) or stationary (plant-covered) dunes, of gibber plains, or of mulga and salt-bush plains. It is difficult to say to what extent this area has undergone normal sub-aerial erosion; there is some evidence that it has actually been com- pletely peneplaned once, with later uplift and a second fairly-advanced cycle of 22 planation, The extent of the latest phase of aeolian erosion, as compared with the normal type of sub-aerial erosion, is not yet known, (c) The Nullarbor Plains —The location and size of these plains are shown in fig. 3A. This physiographic feature is sui generis. Here and there on this vast level, treeless, streamless, limestone expanse, there is indeed some variety to be found, but it does not present itself to the casual observer. The East-West (transcontinental ) railway line, which traverses these plains, runs for hundreds of miles in a direct, unbending line. The area was a broad gulf in Miocene times, and may: have been continuously so from the Cretaceous period, In post-Miocene times it was slowly uplifted, without any apparent warping or fracturing, except along and close to the coastal margin. Its northern margin is now 500-600 feet above sea level. The surface is mainly of rough limestone, covered by a general development of nodular and concretionary lime deposit, with intervening patches of shallow soil carrying low salt-bush and blue-bush. It is distinct from either of the two previously described areas of plain, being a plain of marine deposition, uplifted, without definite traces of planation. In times of exceptional rains, the water lies about in vast “lakes” until it percolates or evaporates away. There are some minor karst features, but these are few and far between. (d) The Mallee Plains —The Mallee area is usually defined on an ecological, climatic and production basis. Wood (Trans. Roy. Soc. S. Austr., vol. lii., p. 359) describes the area as bounded by the 8-inch winter isohyet on the north and the 20-inch winter isohyet on the south (map, page 361, loc. cit.), But all workers do not agree; see also Kenyon (“The Victorian Mallee,’ Govt. Printer, Melbourne, 1923) and Chapman (“Victorian Naturalist,” January, 1922). For our purposes we may consider the Mallee Plains (see fig. 3A) as including: Eyre Peninsula (The “West Coast”), Yorke Peninsula (Y.P.), and that area of plains traversed by the Lower Murray Valley, which lies east of the Mount Lofty Ranges, and south of the Olary highlands, and bounded by the eastern border of the State. The southern boundary extends from the Coorong eastward to the Victorian border. The boundary between the Mallee and the “South-East” is not readily defined; there is no structural or physiographic change; as we approach areas of higher rainfall to the south, the characteristic “mallee” gives way to sheoak, stringybark, banksia, and bracken, and this merges into the different and charac- teristic plains of “The South-East.” Structurally, the Mallee Plains are arcas of horizontally bedded Miocene and later limestones, elsewhere a peneplaned area of ancient crystalline (Pre- Cambrian) rocks that were once possibly covered with such Tertiary limestones, but have lost them by sub-aerial erosion. The plains are characteristically areic. Over the Mallee areas there is much recent alluvium and widespread deposits of reddish, wind-blown sands; in general, wide clayey or sandy valleys alternate with low calcareous or sandy ridges. Alihough the relict is so slight, there is quite a variety of land forms of economic interest, but not yet terminologically defined. (e) The South-Eastern Plains —As described in the previous paragraphs, these plains emerge from the more dry Mallee Plains to the north. They consist of level-bedded limestones (Miocene) with occasional low outcrops of underlying Pre-Cambrian bedrock. Towards the Victorian border, to the east, the limestones are many hundreds of feet thick. The limestone plain has been uplifted and faulted. At least two of these faults, parallel to the coastline, have affected the physiographic development of this area, and are still marked in part by low fault- scarps (see fig. 5). Another remarkable feature of this area is,a belt, nearly 50 miles in width, of successive dune and swale—ancient sand dune ridges that are now dignified om ON \ le N Morambyy Ck. ae \ e a es w SI A Lacepede IF bay = FE ‘Oo | g O > ‘lt i] —— —“RANGES” © VOLCANIC FOCI. y DRAINAGE TO SEA. 20 Miles= rat C.Northiimberlana Fig. 5, Sketch map of the south-eastern areas of South Australia, showing the series of ancient dunes, inter-dune swamps and flats, volcanic foci, fault scarps (Fl and F2), and the main visible outlets of the underground drainage, 24 by the name of “ranges” (Woakwine Range, Avenue Range, etc.). These dune ridges (N.W.-S.I.) run normal to the natural fall of the land (S.-W.), and thus interfere with the development of the natural drainage system. Owing to the soluble character of the limestones an incipient karst formation is developed in places, with dolines, collapsed caves, etc. A series of small volcanic cones in the more southerly part adds further variety to this region. A great part of the inter- dune regions consist of recent alluvial deposits, and there are also widespread swamps and lagoons. Physiographically, this area of ancient dunes is one of extraordinary interest. It appears that the series of ridges shown in fig. 5, with their intervening swales and lagoons, represent a long-continued series of ancient “Coorongs,’ the most ancient being that which lies nearest to the Naracoorte scarp. The last-named feature may be noted in fig. 5, as the ridge (F2) which is intersected by the Morambro, Naracoorte, and Mosquito creeks. Professor Douglas W. Johnson, of Columbia University, who has given special attention to these forms (vide “Shore Processes,” chapter ix.), was attracted by the data in the possession of the writer concerning the stranded dune ridges of the South-East. It would appear that South Australia has in this area a physiographic feature of very high interest from both the scientific and the economic points of view, and one worthy of intensive study. A detailed study of the physiography of this area must have an important bearing on the “drainage problems” of the region, From data kindly made available by Dr. Keith Ward, the writer has drawn five east-west sections across these dunes and swales. Applying to these the criteria laid down by Professor Johnson, the evidence favours a long period of steady uplift of the land. (£) The Plains of the Sunklands.—These are: (a) in the Lake Torrens Sunkland, the Torrens Plains; and (b) in the Spencer-Vincent Sunkland, the Adelaide-Wakefield Plains, the Broughton-Pirie Plains, and the Arno-Cowell Plains. All these plains are built of thick deposits of recent fresh-water alluvium, in some cases many hundreds of feet in depth. In the Torrens Sunkland the alluvium is less well-graded, and the land is of a low economic value owing to the arid conditions. In the Spencer-Vincent Sunkland the three tracts of plain men- tioned are of considerable economic value, owing both to the character of the soils, surfaces, and rainfall, and to the nearness to well-watered highlands and to markets. This is most true of the Adelaide-Wakefield Plains, and least so of the Arno-Cowell tract. The seaward margins of these alluvial plains are in some parts shallow and muddy, with fringing mangroves ; in other parts there are broad sand dunes. The writer has previously described the sand dunes that run from Seacliff to Pelican Point, west of Adelaide, ag a northward projecting “spit,” built gradually forward from base to tip. Further investigation shows that this is so only in the more northerly part ; most of these dunes are simple parallel dunc ridges. (See “Shore Processcs and Shoreline Development,” chapter ix.) General Note re Plains —This brief survey has shown that, both from the geological and the structural aspects, the six areas of plains described, which appear so much alike on first inspection are, on close analysis, distinctly different from one another. Each of these geological and structural facts has its corresponding economic reactions. When consideration of these plains extends to their climatic conditions and economic values, the differences are even more pronounced. VIIL—DRAINAGE SYSTEMS. (a) General—By far the greater part of South Australia is streamless (areic). In all our vast area of 380,000 square miles, there can scarcely be said to be one permanent running stream carrying water that has fallen within our boundaries. It might be thought, therefore, that an account of the drainage 25 systems could be dismissed with but brief mention and description. There are several reasons why this is not the case :— (i.) Where running water is rare and rainfall low, all streams become of greater importance. In a land where water is the great need, every source of supply must be known and exploited. (ii.) In the arid areas of the State the rainfall is not only low, but it is unreliable. In an area of average 5-inch rainfall, that amount of rain may fall in a single day under monsoonal conditions. Thus devastat- ing floods occur in the driest areas, and special types of arid-land watercourses have developed—typical “wadys” in the foothills; wide, sandy-floored, braided stream-courses in the plains. These have their own physiographic and economic interest. (iii.) Prior to the present arid cycle of the interior, and possibly prior to the last great tectonic upliits that affected this area, there was one or more pluvial periods in Central and Southern Australia. Stream courses were then developed, as described by Professor Howchin in his accounts of the “lost rivers” of the interior. (See A.A.A.S., Mel- bourne, 1913, p. 174, and elsewhere), (iv.) Finally, there lie within the boundaries of South Australia the last 400 miles of the course of the great River Murray, the Father of Aus- tralian Rivers. The Murray has been fancifully compared with both the Nile and the Mississippi, and with both of these it has characters in common. But, much as rivers the world over resemble one another, the Murray is really a river of its own kind—with characters all its own, with its own scenic charm of form and colour, with unique economic potentialities and problems. All this is particularly true of the narrowly-restricted South Australian Murray Valley, rather than of any other part of the course of that great river. (b) The Lake Eyre Basin—In the general maps of South Australia the outlines of the various drainage net-works, as preserved by the Lands Depart- ment and other surveyors, are usually rendered almost undecipherable by the necessary addition of roads, tracks, mountains, and other cartographic data. It was, therefore, considered worth while, to assist in the independent con- sideration of these important drainage networks, to prepare sketch maps of various drainage areas clear of the embarrassment of other details. As already described, the Lake Eyre Basin lies in an area of low and unreliable summer (monsoonal) rainfall. Lake Eyre itself lies within the 5-inch rainfall line, the most arid portion of Australia (note 10-in. isohyet, fig. 6). In the north centre of the area is a large patch of drifting sand-dune desert, where there are no stream courses whatever. For the rest we have a series of streams, chief of which are the Finke, Diamentina (or Diamantina), and Cooper’s (Barcoo) Systems, which run only in times of heavy flood. Characteristically, they are wide, sandy-floored streams, wandcring almost aimlessly over the plains, but in places depositing considerable depths of silt along their banks (4 feet in about 40 years at Burke’s Tree, Innamincka, vide Proc. Roy. Geog. Soc. S.A., Session 1927-8, p. 14). For the greater part of the year such streams are dry, but along their courses, in some places, valuable “waterholes” persist throughout the dry years. Adjoin- ing such waterholes most of the ‘‘station” (ranch) settlement of these areas takes place; in other places, potable water may be obtained in the sands of the dry bed. Apart from the apparently “aimless” courses of these streams, their braided character, their clay-bottomed waterholes, and the canal-like character of their B iz {4 m - «x zr een Ve 100 120 A KEDON NEL SCALE (Miles).

The 5-inch and 10-inch isohyets are shown; Lake Eyre itself is 30-40 feet below sea level. 27 beds in some of the lower reaches, there are one or two other features worthy of mention. One of these is the number of “tributary” streams, apparently with a well-developed system, that no longer reach the parent stream unless in excep- tional floods; these perhaps point back to the pluvial period before mentioned. Another noteworthy feature is the remarkable stability of billabong channels, such as Strzelecki Creek; Howchin thinks this was the original course of the Cooper. A third feature is the occurrence of “lagoons” throughout the area— basins that have gradually become silted up with the sediment carried by these wi = 5 3 <= ~ 3 4) V8) 3 ev Zz Scale -(miles) 20 40 ©0 80 Fig. 7.

The chief faults are marked by bold lines shaded on the side of the uplift, the almost straight Torrens Fault on the west, and the two curving fault series bounding the Flinders Horst. Except on the ranges, the rainfall is everywhere less than 10 inches per annum. streams in flood time. The central “lakes,” such as Lake Eyre itself, come under this heading. Dr. Keith Ward has pointed out that the definite and regular stream pattern of these rivers is found only on the areas of Cretaceous or older rocks. On the sandy plains, braided and ill-defined courses are the rule. Where the Hay, Hale, and Todd reach the outcrop of the Jurassic intake beds, their surface flow ceases. As suggested by Winnecke in 1886, this is probably also the case with the Finke 28 River, which no longer (in Dr. Ward’s opinion) unttes with the waters of the Macumba. See also Madigan’s account of the aerial reconnaissance of this area (Trans. Roy. Geog. Soc. of A’asia, S.A. Branch, 1930 volume). The most important physiographic fact regarding the Lake Eyre drainage basin is, that it is largely tectonic in origin. We may follow Howchin in his hypo- thesis that it was not always as it is now, but that this “basin” once continued in a wide valley towards the south, with great streams, in either one or more valleys, emptying into the occan towards what is now Gulf St. Vincent. Howchin has shown that enormous deposits of fluviatile drift occur in various parts of the State, and suggests that during the pluvial period great river courses did continue southward. Certain it is that a contemplation of the geology and tectonics of the southern part of the Lake Eyre Basin leaves one with the impression that a great drainage system has here been frustrated, stopped, dammed back (see fig. 6). This is particularly the case when one considers the remarkable termination of Strzelecki Creek in a chain of lakes, lying normal to the stream course, along the base of the lately (? Pleistocene) uplifted mountain masses there. This abnormal physiographic feature had a pronounced influence on the history of the explora- tion of the interior, greatly puzzling the early explorers. (c) The Lake Torrens and Lake Frome Basins—Much that has been said of the Lake Eyre drainage system applics also to the Lake Torrens and Frome systems. Indeed, the Lake Frome drainage is really connected up with the Lake Eyre System in that chaotic, futile, and uncertain manner that one finds where, owing to the level character of the region and the mode of origin of the streams, the latter have played but a small part in forming their courses and “valleys.” These drainage systems are purely consequent upon, and closely reflect the facts of, the later tectonic movements of the northern Tlinders Ranges. In the centre there has been the uplift of the horst of the Flinders, with the down- sinking of the Torrens Sunkland to the west, the latter being terminated on the western side by the Torrens Fault. To the east there is the less well-defined Lake Frome Sunkland, which rises gently towards Broken Hill and the Olary Spur. It would appear that the streams are mainly subsequent to, and consequent upon, these movements. It is true that within the Flinders Ranges the stream valleys cut across the beds and act independently of structures in many cases, suggesting that their courses were begun on the old peneplain surface of the rising Flinders, In other cases, as at Wilpena Pound, the rock structures have greatly affected the stream courses. It is likely that a study of the Sicecus River will provide information of special interest regarding the physiographic history of the area. The appearance of the Hookina and Parachilna gorges leads one to suspect a Jater and more rapid uplift of a segment of the western horst, as in the lower Mount Lofty Ranges, a Fig. 10. Sketch map of portion of South Australia to show the stream courses of the southern Mount Lofty Ranges. The 500-foot contour line is shown, and the chief reservoirs are indicated by black triangles. 32 from south to north, At one season these wide plains may be rich with waving wheat crops, at another they are vast sheets of moving water, and yet again, and more often, bare brown dust and mirage. (e) The River Broughton—This stream passes through one of the most productive wheat and wool areas of the State. As shown by fig. 9, it has a drainage pattern of a curious and interesting type, testifying to the influence of varied successive factors in its history. The north-south “ridge-and-valley” structure of the lower ranges hereabouts is remarkably well shown in Crystal Brook, Rocky River, Bundaleer Creek, the Hutt and Hill Rivers, ete. Whether these important structural features are due to “tilted blocks” (which is commonly believed), or to differential erosion of hard beds along their strike (which is also possible), has not been determined. The main course of this stream is strikingly different from most of its tributaries, and it may possibly be antecedent. A wide area of deltaic plain, from Port Broughton ta Port Pirie, has been deposited by this vigorous stream. In times of high flood, portion of the waters of the Broughton flow once more into the old Pirie Creek (the harbour of Port Pirie) near Solomontown. It is a fortunate fact for the harbour of Port Pirie that this stream deserted its old estuary, thus greatly minimising the difficulties of siltage and the cost of dredging at that important port. (f) The Light, Gawler, Torrens, Onkaparinga, etec-—The portion of South Australia that is shown in fig. 10, namely, that part which lies between the eastern shores of Gulf St. Vincent and the last stretch of the Murray River (from Morgan to the Mouth), is the most favourable part of the State for the study of normal sub-aerial erosion. The legal name of this area, no longer used, is “Sturtia.” It is the only extensive exoreic area in the State, and even then, as may be seen in the figure, many small streams die out on the alluvial plains. It is to this area that the greater number of the people of South Australia look for their water supply; it is in the upper valleys of these streams that most of the storage reser- voirs are, and will! be, built. Much has been written regarding certain of these streams, particularly the Torrens and the Onkaparinga, and it is likely that we are approaching a general agreement regarding the manner of their origin, and of their age. It may be seen from fig. 10 to what a great extent the structure of the ranges has influenced the character of the stream-pattern; this is in favour of a consequent origin for the streams. On the other hand, we have the lacts that the ranges are in general higher on the western side and with dominant north-south structure lines; yet most of the basins drain to the west. The hypothesis that appears to best meet this difficulty is that there have been two stages of uplift, as elscwhcre outlined, that the stream courses are in part tectonic, in part consequent, and in part antecedent. Under this hypothesis, it is conceived that the streams were formed on the rising limestone overmass at the time of the first uplift (fig. 4). The block structures of the ranges imposed something of a tectonic character on the valleys, and when these streams had reached the maturity of the second peneplain, they were antecedent in relation to the Pleistocene uplift, hence the gorges, etc. There may also have been capture by the stronger western streams in both the Light and the Para basins. Within the hills themselves the relief is high and the problems are many. A general fact is the contrast between the young topography of the strcam valleys in the western part of the ranges, and the gentle, mature topography in their upstream areas. This applies more particularly to the country around Mount Pleasant, which represents a stage of erosion, in very resistant crystalline and 33 Archaean rocks, far older than that of any other part of the southern Mount Lofty Ranges. Here again is evidence of two distinct and widely-separated stages of uplift. The “toe of the peninsula,” from Myponga Creek and Inman Valley south- west to Cape Jervis, is a wonderland of physiographic interest that is almost untouched, The influence of rock types and rock structures of the mast diverse kinds is to be seen here. Ancient pre-Permian landscapes are exposed, and incorporated into present-day features. Howchin has shown that the Finniss, ° Inman, and Hindmarsh Valleys have in part exhumed a pre-Permo-Carboniferous glacial landscape, and are thus in part super-imposed on the buried pre-Cambrian rocks. Fault coasts, marine erosion, valleys and ridges in extreme youth and high relief, have combined to keep this area in an almost unsettled state, and it remains a most promising place wherein to search for keys for the unlocking of the structural secrets of the Mount Lofty Ranges. (g) The Lower Murray Valley.—lIt is not proposed to enter into the physio- graphic history of the Lower Murray in any detail; on this matter the writer has been collecting detailed geological and geographic information for other purposes. It is appropriate, however, to discuss in a broad way, some of the factors that may have determined the present course of the river. Tate’s threefold division of the Lower Murray Valley still holds good, though it may be noted that the first observer, Charles Sturt, also detected the critical importance of Overland Corner. (See also Geological Notes, South Australian Almanack, 1841.) Tate’s divisions are: (1) The Lacustrine, from the Mouth (Encounter Bay) up to Wellington; (2) The Gorge, in marine Tertiary limestones from Wellington to Overland Corner; (3) A much wider valley, cut through lacustrine beds, irom Overland Corner to the border of the State. Professor Howchin (Trans. Roy. Soc. S. Austr., vol. liii., 1929, p. 167) presents valuable evidence, and discusses various possibilities regarding the physiographic history of the Lower Murray. If we consider only the precipitous, cliff-bordered, mile-wide gorge in the level-bedded Tertiary limestones between Overland Corner and Wellington, it is impossible to regard this as dating back to the close of the period of Miocene deposition and the beginning of the sub- sequent land emergence. It is difficult even to picture this gorge as one dating from the early Pleistocene, when one considers the mighty valleys carved out in harder rocks by lesser rivers during Pleistocene time. Not that any worker has definitely suggested that the Murray Gorge is either Miocene or Pleistocene inage, Although it has been called an old river, on account of its very low grade, it has many of the characteristics of youthfulness. The Pleistocene (fluviatile and lacustrine) beds through which the river valley runs above Overland Corner, and whose sands and gravels have been so widespread over the area, may indeed have covered the whole of the Mallee lime- stones, and in a great estuarine pre-Lower-Murray period they may have extended well to the west over the area where the Mount Lofty Ranges are now. It was only by depression below base level, with a probable covering of alluvial sediments, that the Murray limestones could have been preserved. Meanwhile the waters of the Darling, Murrumbidgee, Lachlan, and other contributors sent down their silt to the great central area, somewhat more vigorously and consistently than the Frome and Cooper do to the Lake Eyre de- pression to-day. With the continuation of the general uplift that included the formation of the Mount Lofty Ranges, the limestones of the Murray plains commenced slowly to come into the picture; but there were as yet no limestone beds sufficiently ~ ei — North West B bl = aes = Wshyy yee ced yeyuat yy ANS a) mA 1 1 RANGES’ Jt NS AG iaa: Pyap Bend Par Oat. vivir Wh vs ‘ Hy) a MT LOFTY w an } THE Se MURRAY Fy ye . iil MPI yyy i Nowy VN They ah ao Chucka Bend .7 MALLEE WN MAY ) poy yyy \ty yyy dp I ) : Way, IAI WS ody Scale L_) 4 Miles Fig. 11.

The uplifting of the Murray River limestones appears to have been remarkably uniform, and one may travel along the river cliffs for miles and miles without noting any appreciable deviation from the horizontality of the beds. Nevertheless, careful observation shows that there were certain irregularities in the movements of uplift, the evidence and the effects of which are distinctly to be seen today :— Ci.) The uplift was greater near the Mount Lofty Ranges to the west, and the beds underlying the Murray Mallee were warped gently down- wards towards the north and the east. (1i.) There was a general emergence of the whole limestone area, and of its covering burden of fluviatile and lacustrine sediments. (iii.) Parallel to the eastern Mount Lofty Faults, there occurred some faults or warps in the Tertiaries themselves; there is good evidence that one of these runs almost N.-S., east of Sedan, 100 feet high, still visible as a gentle scarp. Another parallel warp downwards to the east is believed to have marked the present course of the Murray between Morgan and Chucka Bend. As may be seen at the North-west Bend, this warp involved a 5° dip due east in the otherwise horizontally- bedded limestones, (iv.) There was a third more gentle easterly dip at Overland Corner, a feature of very high importance, and with excellent field evidence. (v.) At the same time a fold or upwarp took place parallel with the present coastline, north-west-—south-east; this may be seen as a scarp at Siruan and Naracoorte (see fig. 5, F2), and it continues north-west into what is known as the Marmon Jabuk Range and onwards (see contour lines in fig. 11). Because of this upward fold the Miocene Tertiarics, etc., already given a gentle plunge to the east, were also given a gradual dip to the northward. While these changes were taking place, the waters of the great contributing rivers of New South Wales and Victoria had combined to form the Lower Murray. With uplift, this stream commenced to cut into its own alluvial beds, and in the more uplifted areas (to the west and south) completely destroyed them. East of the Overland Corner dip, the soft alluvial overmass has not yet been stripped away, and still protects the buried limestones. But the river in these softer rocks is enabled to swing and sweep in an almost unrestricted way, and we thus get, above Overland Corner the wide valleys and fertile slopes that are of such great economic importance to the State in the Cobdogla, Berri, and Ren- mark areas. During the process of side-swinging in the incoherent fluviatile beds, the river has moved both south and north, On the north there is no limiting factor, but on the south, near Loxton, and between Loxton and Overland Corner, the down-cutting river met with the more resistant, gently-plunging, submerged Tertiary limestones, and thus was deflected northward from the Great Pyap Bend, and directed north-west to the place where the river had become entrenched in the limestones at Overland Corner. Possibly the farthest upstream point where the underlying marine limestones are seen is at very low levels at Kaesler’s Cliffs, below the old Bookpurnong Woolshed landing, where J, F. Stasinowsky, of Loxton, collected a whale’s scapula, large molluscan casts, etc, In the gorge that is wholly limestone, from Overland Corner downstream, swinging and sweeping are more difficult, but the work is carried steadily on, and 36 the remarkably even parallelism of the sides of the gorge testifies to the general evenness of the erosive work done here. The minor tilt or warp that ran through Morgan, which was possibly reflected in the one-time overlying lacustrine and fluviatile beds, would be sufficient to deflect the river and to send it on that other- wise inexplicably sudden turn to the southward. Thus we have an explanation for the sharp change of direction of the river at North-west Bend, whence the pre- cipitous mile-wide gorge runs almost due south for about 50 miles, keeping parallel to the tectonic lines of the Mount Lofty horst, and (it is suggested) following the line of a surface feature due to a structural break in the Miocene limestones and later sediments of the area. Apart from a minor deflection at Big Bend, where barely hidden Cam- brian rocks may have influenced the course of the stream, there is no important change of direction until the river meets the upwarped (or upwarping) ridge that is in part indicated by the Marmon Jabuk Range. This would perhaps account for the wide swing westerly from Chucka Bend (see fig. 11) that carries the river round to Tailem Bend, where it again follows the normal fall of the country towards the sea. 37 CONTRIBUTIONS TO THE ORCHIDOLOGY OF PAPUA AND AUSTRALIA.

Papua. Owen Stanley Range on Nomi-Ake Divide, Salawakel at 7,000 feet. C. E. Lane-Poole, No. 526, November 23, 1923. Of the 39 species of this remarkable genus published up to the present, only one (M. Lawesti, Schltr.) has been reported from Papua, The most westerly 38 representative is found in Amboina, and another has recently been described by J. J. Smith from the neighbouring island of Serang (Moluccas). The most easterly species is M. paradoxum, Schitr., from Samoa, and the most northerly is M. ponapense, Schitr., from the Caroline Islands. All other known species are indigenous to New Guinea. The flowers of the new species appear to be closely related to those of M. monticola, Schltr., but the plant differs very materially in the number and shape of the leaves, and in the characters of the pseudobulbs, as well as in certain floral details.

Lane-Poole, No. 529, November 23, 1923. The genus Spathoglottis is richly represented in the Island of New Guinea, which may be regarded as its centre of dispersion, but only a few forms have hitherto been reported from British Papua, vz.:-—S. stenophylia, Ridl., S. papuana, Bailey, and its var. pubeiflora, Rogers and White, and S. Lane-Poolei, Rogers. schlechter, who has paid special aitention to the genus under natural condi- tions, states that the species diminish markedly in number as we ascend the moun- tains. The new species is apparently rather closely related to S. parviflora, Kranzl., another alpine form, but differs from it in the shape of the intermediate lobe of the labellum and also in other floral details.

Flowered Botanic Gardens, Brisbane, January, 1930. Forwarded by C. T. White, Government Botanist. Owing to the intensive study and publications of certain botanists, particularly Dr. Schlechter, Dr. J. J. Smith and Mr. H. N. Ridley, the genus Phreatia, Lindl., has suddenly increased during quite recent years from a very few to approxi- mately 225 species. It is widely distributed from India, across the Malay Archi- pelago, Papuasia, Moluccas, Celebes, Philippines, Formosa, Australia, New Cale- donia, New Hebrides, Fiji and other Pacific Islands. New Guinea alone claims not less than 119 species, and this must be regarded as its probable centre of disscmination. It is, however, but poorly represented in Australia. Up to the present only two species have been recorded on our census, vig.: Phreatia limenophylax (Endl,), Bentham, and P. Baileyana, Schltr. [= P. pusilla (Bail.) J, Rolfe. Both of these, like the majority of species belonging to this genus, are extremely dwarfed plants. The former was originally discovered by Ferdinand Bauer on Norfolk Island, and was carefully illustrated by him in a plate now in possession of the Vienna Herbarium. It was described by Endlicher under the name of Plesxaure limenophylax. Subsequently, when writing the sixth volume of the Flora Australiensis, Bentham became the innocent victim of a discreditable deception by H. G. Reichenbach, which led him to publish his belief, that the mainland plant, found by Dallachy at Rockingham Ray, Queensland, was identical with Bauer’s plant from Norfolk Island. This belief was founded upon error, an error which was accepted and followed by Pfitzer and many eminent botanists until the true facts of the case were published by F. Kranzlin in 1911 in his pre- fatory remarks to the “Dendrobiinae,” part IL, page 12, and again in his mono- graph on the genus Phreatia in the same work, pp. 20’and 21, where he also pub- lishes Bauer’s original illustrations. In describing the Rockingham Bay plant, Bentham states that he had not seen the pollen-masses as the flowers were too advanced, He makes no further refer- ence to the column. Kranzlin is of opinion that this plant was an Oberonia, I have had the opportunity to examine “the best” of Dallachy’s specimens in the Melbourne Ilerbarium. It was collected in 1870, and was in a state of bad preservation, In the most promising of the three flowers still attached, the upper portion of the column and, of course, the pollinarium, were absent. There was no indication of a column-foot or of a mentum. This lends colour to Kranzlin’s suggestion that the plant was not a Phreatia but a species of Oberonia, a con- clusion which he reached for other reasons. ‘aking all the circumstances into consideration, it is at least a very doubtful member of the genus to which it has been ascribed and should be deleted from our census. Fresh material from Rockingham Bay may yet place the matter on a scientific basis. The new species does not appear to bear any very close relationship to other members of the genus. Its very wide leaves and large size and small flowers readily exclude the vast majority. A few species are comparable in size, but all of these appear to differ considerably in habit or floral details. 41 Calochilus saprophyticus, Rogers, n. sp.

A pale saprophytic plant, rather robust, about 20-25 cm. high, with a large thickened tuberous rhizome similar to that of Gastrodia, Stem yellow with two membranous imbricate sheaths at the base. Bracts 2, yellowish-pink, subulate, about 7 cm. long. Leaf incomplete in my specimens, rather fleshy and stout in its lower part, channelled, apparently lanceolate. Raceme 3-10-flowered, subtended by a yellow subulate bract about 4 cm. long. Flowers stalked, rather large, pale saffron-coloured with exception of the reddish-brown striped petals and the yellowish-purple labellum.

Column short, widely winged, a purple gland at the base of each wing, convex at the back, fleshy. Anther rather long, incumbent, subobtuse, greenish-yellow. Stigma triangular, just below the anther; no caudicle present. Victoria. Cravensville, A. B. Braine and F. J. Supple, October 21, 1918, and November 7, 1920, Mr. Braine states that it was growing in an almost shade- less place. The very characteristic habit of this species readily separates it from its congeners. In structure, the flowers approach rather closely to those of C. campestris, R, Br., but they differ not only in colour, but also in the shape of the petals, which are much narrower and very much more acute; likewise in the extremely short ligule as well as other details of the labellum. Including the new species, the genus now comprises a small, well-defined group of nme members, Eight of these are confined to the Commonwealth and New Zealand, and one is indigenous to New Caledonia.

Anthera mucronata, vix medium columnae superans. Stigma scutiforme vix ad medium antherae attingens. A glabrous slender plant, reaching a height of 45 cm., a loose cylindrical membranous sheath at the base of the stem about 5-6 cm. long. Leaf lanceolate, acuminate, sheathing at the base, reaching beyond the middle of the scape. Cauline bracts 2 or 3, subulate or acuminate, vaginate at the base. Raceme loosely multiflowered, about 9-14 cm. long. Flowers 10-14, rather large for the genus, yellow with brown dots, resembling those of T. fiscolutea. Ovary subconical, about 1-0 cm. long, on a slender pedicel about 1°3 cm. long. Perianth segments elliptical, subacute, spreading or suberect, about 1°6 cm. long, 0-5 cm. wide. Column elongated, erect, incurved at the apex, about & mm. long, yellow, spotted, rather widely winged, produced high above the anther, 3-lobed at the apex ; middle lobe incurved, not crested on the back, deeply emarginate, the border otherwise entire; lateral lobes ascending, densely papillose-bearded, higher than the central lobe.

Sargent, October, 1929; Ben- cubbin, R. E. Edmonsen, October, 1929; Dalwalinu, Colonel Goadby, October, 1929. The new species is closely related to T. villosa, Lindl., and T. tigrina, R. Br., The former is easily distinguished by its very broad villous leaf, horizontal lateral lobes and crested middle lobe of the hood. The latter is a much smaller and more slender plant with a narrow lmear leaf, and flowers about half the diameter of TL. Sargent. ‘Vhe middle lobe of the hood is 3-partite and crested. More remote relatives are T. fusco-lutea, R. Br., and T. stellata, Lindl. Both these species may be readily recognised by the deeply dissected margins of the column-hood with its curious clavate dorsal appendage and the characteristic elongated recurved terete apex of the anther. The former species has also a very broad glabrous leat. The colour of the flowers, and the fact that the lateral lobes of the column are not tufted with long cilia, removes our plant from other members of the section Cuculluria where the prevailing colour is mauve or purple. Thelymitra D’Altonii, Rogers, n. sp. Gracilis, circa 15-22 cm. alta.

Braine and Miss May Braine, September 26, 1929. 43 Plant slender, 15-22 cm. high. Leaf glabrous, channelled, longitudinally ribbed, subacute, sheathing at the base of the scape; lamina linear, spiral, widely dilated below.

Column rather stout, entirely blue, about 6 mm. high to apex of anther; lateral lobes of hood bright yellow, broadly elliptical or orbicular in outline, plano- convex, shortly stipitate, erect behind the anther, about 1:0-1°5 cm. long; middle lobe much shorter or obsolete, without atry dorsal crest. Anther bright yellow, incumbent, very conspicuous, oblong or oblong-cuneate, truncate or very obtuse at the apex, bilocular. Stigma very prominent, situated just below the anther, large, orbicular or transversely oval, almost pedicellate, concave, disc-like. After very careful consideration, it has been thought necessary to describe this dainty little plant separately. It is evidently a near relation of 7. spiralis, Lindl, and T. variegata, Lindl., two ill-defined and possibly composite Western Australian forms, and may ultimately be regarded as a variety of one of them. In the present state of our knowledge, however, it is impossible to say which, as one or other of the plants known under the above names may in the near future require further subdivision. In his Swan River Appendix to vol. xxii. of the Botanical Register, 1839, p. 50, Lindley published two new species of Thelymuitra (Macdonaldia), which he named T. variegata and T, spiralis, These short descriptions lack details of diagnostic importance, but for convenience I quote them here :— 1. T. “variegata; floribus purpureis, sepalis petalisque linearibus acuminatis, cuculli laciniis lateralibus lanceolatis subcarinatis intermedia obsoleta, anthera carnosa obtusa elongata loculis brevibus semicircularibus mem- branaceis.” 2. T. “spiralis; folio radicali spirali caulino solitario ovato, caule unifloro, floribus purpureis, cuculli laciniis lateralibus carnosis dolabriformibus intermedia obsoleta, anthera obtusa apice papillosa.” It will be noted in these descriptions that the leaf is undescribed in T. variegata, but stated to be spiral in the other; the flowers are purple in both; the intermediate lobe of the hood is absent or rudimentary in both, and there is no reference to the presence of a crest in either; the lateral lobes in T, vartegata are lanceolate and subcarinate, in T. spiralis they are fleshy and hatchet-shaped. The name variegata implies a character (presumably in the flowers) which receives no reference in either description. Bentham retained only the former species, describing the leaf as much dilated at the base with a lamina lincar and often undulate; the flower dark-coloured and variegated ; lateral lobes of column nearly 4 mm. long, obtusely oblong,‘ connected behind the anther by a crest. He does not regard the spiral leaf as a constant or specific character. Presumably Bentham had access to Lindley’s types, but it is not known whether these were in a good state of preservation or to what extent they were supplemented by other material. R, D. Fitzgerald, who illustrated on the spot plants which he believed to belong here, shows the lateral appendages as falco-elliptical or falco-oblong. It is by no means easy to reconcile these varying 44 descriptions. In my own material from Western Australia, the flowers are sometimes ptnctate or variegated, sometimes not; the lateral appendages vary considerably from oblong to elliptical, but are always more or less elongated, in one specimen reaching the length of 5 mm, It is difficult to avoid the conclusion that Bentham and other authors have included more than one species under the same name, The matter can only be cleared up by a plentiful supply of material, which it is hoped will-be forthcoming next season. Mr. D’Alton, who has worked so energetically in the elucidation of the flora of the Grampians, scent me a specimen of the new orchid eight years ago, but owing to the hot weather and long journey it did not arrive in a condition suitable for critical examination. I am indebted for my present supply of satisfactory material to Mr. and Miss Braine, In his letter Mr. Braine states that they collected 17 specimens, in all of which the flower was solitary. The contrasting colours in the flower are most delightful, and in this respect no other member of the genus known to me rivals it in beauty. Prasophylilum Hartii, Rogers, Tr. Roy. Soc., S.A., li, (1927), p. 8 Var. patviflorum, Rogers, nov. var. Differt a forma typica floribus minoribus globosioribusque ; petalis lineari-falcatis, incurvatis, sepalo dorsali brevioribusque ; parte apicali labelli acutius flexa. Victoria. Singapore in Wilson’s Promontory, Miss E. Devonshire, November 9, 1928; Port Albert, A. J. Tadgell, November 21, 1928. This very distinct variety is readily recognised from the typical plant, by its more slender form; by its much smaller and more globular flowers, its differently- shaped petals which are also incurved and shorter than the dorsal scpal; likewise by the more acutely flexed apical portion of the lip. Except that it possesses the extremely characteristic labellum of P, Hartii, it might very reasonably be regarded as a distinct species. Microtis magnadenia, Rogers, n. sp.

This is a large Microtis, and in its general habit is most nearly related to M., porrifolia, Spreng. It differs, however, from that species in the shape of the lateral sepals and in the fact that these are neither recurved nor revolute but horizontally spreading. ‘he calli on the labellum are also quite distinctive. They are very large and very conspicuously elevated above the level of the laminar surface. The anterior one is light-coloured, and the basal ones are dark green. These large glands at once attract attention, and this character has been embodied in the specific name of the plant. Caladenia rigida, Rogers, n. sp.

By Heptey Hernert Fintayson, South Australian Museum. [Read November 14, 1929. ] Prates I ro III. Macropus (WALLABIA) RUFICOLLIS TYPICUS. This, one of the oldest known of the kangaroos and wallabies, and one of the most widely distributed, has been the subject of more general and anatomical study than any other, except M. giganteus. The name used above, although long established, was called in question by Cabrera in 1919 (1), who pointed out that Desmarest had applied it to an insular representative of the species, the mainland animal being specifically dis- tinguished as M. rufogriseus. In referring to the species as represented in South Australia, Wood Jones (2) followed Cabrera. Since, however, the two names were applied simultaneously by Desmarest, and since the King Island animal in question is doubtfully separable, even sub- specifically, from that of the mainland, there is no risk of any confusion of identities. The objections to the use of the name ruficollis would thus appear to be slight, and the case is one in which convenience arising out of long usage might well be given greater consideration than the formal application of a rule. Distribution and Habits—In the eastern coastal districts of the mainland the species“ is represented throughout a tract of country nearly 1,000 miles in north and south extent—its northern limit apparently lying in the Upper Dawson Valley of Queensland at about 25° south latitude, and its southern limit in the Otway Peninsula at about 39° south. Throughout this tract its distribution clearly follows, with few digressions, the foothills of the Great Divide and its associated ranges, and this may be regarded as its typical habitat, but a westerly excursion from the Otway Ranges has been responsible for the occupation, not only of the Grampians, but of much of the timbered plain country of Western Victoria and South-Eastern South Australia as well. Although at the present day it is the only member of the subgenus Wallabia which may be said to be well established in South Australia, its status here is merely that of a western outlicr of a specics which is typically eastern in origin and occurrence. It is thus much less characteristic of this State than the Toolache, whose whole evolutionary history has apparently been worked out here and whose range was exceedingly circumscribed. The tract of country occupied in South Australia by M. ruficollis typicus is coterminous with that of the subgenus as defined in Part I, of this paper and corresponds closely also with that of M. greyi. At the present time it is not found west of the River Murray, but formerly was well represented there, occupying much of the county of Sturt, where, however, it was apparently con- (1) In South Australia it is known to the settlers as the “Brusher,” commonly con- tracted by the present generation to “Brush.” The aboriginal word in the lower South- East is “Carlo.” 48 fined to the river flats and foothills, and its failure to occupy the Mount Lofty Range proper has already been noticed. Not only its distributional limits, but the density of its representation correspond roughly with that formerly obtaining for greyi—there being a rapid falling off in numbers on passing north from the well-watered and well-grassed country of the lower South-East to the much less favourable conditions of the mallee lands. Its presence in this latter type of country is remarkable, as it con- stitutes an environment widely different from that of its typical habitat in the east, and in no other part of its range does it appear to invade similar country, Although the same boundaries equally define the limits of the range of both M. greyi and M., ruficollis typicus in South Australia, the sharp division of the country into distinct habitat zones of widely different character is responsible for a very strong contrast in their local distribution and occurrence. Whereas M. greyi was to be found exclusively on the most open grass country, almost devoid of timber and even undergrowth, the natural station of ruficollis was the heavily timbered country. This, as already pointed out, is itself of two distinct types: Red and blue gum forests growing on comparatively rich soils and free from undergrowth, and the stringy bark “ranges” which are interspersed throughout the wide sandy heaths and which, while sharing with the latter the typical heath flora of dwarf leptospermums, xanthorrheas, and casuarinas, possess in addition the bracken fern. The “ranges” are thus provided with a plentiful and frequently dense undergrowth under the timber. Formerly, when settlement was little advanced and had caused little inter- ference with the fauna and its distribution, it is stated to have occurred on both types of country, but much more plentifully on the former, and since these smooth- barked gum forests make a much closer approach to the general character of its habitat in the east, this would scem very probable. In some localities the term “scrub-brush” was applied to distinguish the wallaby of the ranges—these animals being generally poorer in condition, and frequently infested with lice. ‘To-day, owing to the destruction of much of the timber, and to the closer settlement of the country, it has disappeared altogether from the gum and grass country, but, unlike the Toolache, to which the changed conditions spelt extinction, it has fallen back on the rougher country, and, in spite of persecution, has most successfully adapted itself to the more rigorous conditions of the scrub. The contrast in habitat of the two species extends to, and is no doubt correlated with, similar differences in many details of their habits, structure, and temperament, and the effect of abrupt changes in environment in giving direction to their more characterislic specializations is plainly apparent, Unlike the Toolache, semi-gregarious and very local, the Brusher is a wide- ranging, almost solitary, species, with no noticeable tendency to the formation of colonies, being fairly uniformly distributed throughout all country suited to its needs. Its occupancy, to-day, is, in many places, very sparse and perhaps inter- mittent, but in almast any stringy bark range it is possible to find evidence of its recent presence; whilst, in the case of the Toolache, much of the black rush and tussock country, which forms its peculiar habitat, appears never to have been utilized by it. For the greater part of the year the normal social unit is a trio, a male and female, accompanied by last season’s young, but the attachment of the male to the trio is loose and intermittent, and a large proportion of the older males would appear to be always solitary, It is true that small parties are occasionally met with on especially attractive feeding grounds, and on winter afternoons similar parties of twelve or more may sometimes be surprised basking in a clearing on the sunny side of a range, but 49 these associations are quite temporary. When disturbed, the individual members disperse on their own initiative and in many directions without giving evidence of being dependent on a leader, as is the case when a “mob” of one of the gre- garious species is put up. In its feeding it is essentially a browser. The beautiful groves of Banksia marginata, which occur as occasional oases in the heaths, and which are generally free from undergrowth and lightly grassed, are attractive to it, and where crops are grown in close proximity to its cover it makes itself as unpopular to the settler as the kangaroo, but at the present day, at any rate, it seldom makes forays out into the open grass country, and, practically, the whole of its feeding is done in the ranges and on the edges of the heaths, Here the bulk of its food is derived from the young shoots and leaves of the typical heath species enumerated above, and examination of the stomach contents of a considerable number of specimens plainly indicates that the dwarf Xanthorrhea semiplana is, quantitatively, the most important of these, In general disposition it is exceedingly shy and secretive, It is rarely seen about during the daylight hours, unless driven from its camp, but lies up during the day in the densest cover, frequently in a bracken-filled hollow. It appears to have an instinctive dread of open situations, and when feeding in such places is exceedingly alert and suspicious and far more difficult to approach than the black-faced kangaroo whose feeding grounds are similar. Its love of dense cover may be due (in summer at least) as much to a desire for coolness and shade as to an instinctive seeking after security, since it displays a marked intolerance to heat, In captivity it is obviously distressed by a degree of exposure to the summer sun, which has little effect on M. greyi or M. giganteus. In summer, a period of cool and dull weather will sometimes tempt it out to feed during the afternoon, and in winter, after protracted cold and wet condi- tions, it will come abroad to avail itself of momentary sunshine, but ordinarily its departure from a strictly nocturnal habit involves only the hour before sunset and the hour after sunrise. As regards reproduction, it is frequently stated by settlers and others that the “breeding season” is in the early spting, and the statement is found also in books on marsupials. The term “breeding season,” however, is one of rather vague connotation as applied to marsupials, and popularly is applied indifferently to the time of union of the sexes, and to the completion of the pouch-life when the fully-developed young first begins to lead an independent life. The latter is apparently the more usually accepted definition, locally. It is probably true that the majority of “joeys” leave the pouch permanently during the warm weather of September and October, but irregularities are so frequent and so considerable that no hard and fast rule can be laid down, but as with most macropods, young, at all stages, from the naked embryo to the fully- furred but still dependent “joey,” are found in the pouch at all seasons of the year. These irregularities arise partly from the absence of a definite pairing season, the sexes uniting, apparently, without regard to the time of the year, and partly also, no doubt, to individual differences in the length of the period of gestation, such as are well authenticated in kangaroos, but even more to individual differences in the rates at which young develop in the pouch. When put up before dogs on the edge of a heath the speed of the Brusher is considerable for the first 100 yards, or so, but it is soon blown, and if it can be kept in the open its capture presents little difficulty to the average kangaroo dog, Its immediate endeavour, however, when alarmed, is to make back into the cover of a range, and here, amongst the timber and jn the tangle of undergrowth, 50 its dodging and doubling are so adroit as to baffle the smartest and most persistent of dogs. When so engaged its movements are comparatively noisy, but if it takes alarm while under cover, it is capable of making its way through the undergrowth with remarkable speed and in almost complete silence. Indeed, its “sneaking” abilities are phenomenal, and a 50-Ib. buck, standing normally 4 feet high, will slip through a dense bracken thicket, not only without once exposing himself, but with scarcely a tremor of the surface greenery to mark his path. The habit of interrupting its flight momentarily to look back at the source of alarm, so common in species living in open country, is seldom to be observed in the Brusher, If it is surprised in thick cover, however, and is uncertain of the direction of the approaching danger, its apprehensions will sometimes induce it to make a series of vertical leaps, which increase its range of vision by carrying it momentarily above the level of the undergrowth. As it lands and “takes off” from the same spot each time it betrays its position in an unmistakable way, and the habit is thus equally fatal. As regards its position in the fauna of the State, it would appear that although greatly reduced in numbers from that formerly obtained, it is now, for the present, at least, holding its own. Although nominally protected for part of the year, it is persecuted constantly with dogs, both in season and out, partly for the “sport” involved in its killing, partly for its handsome pelt. It survives this persecution, partly by virtue of those qualitics which have already been touched on in discussing its habits, but, chiefly, through the existence of great tracts of rough, unsettled country, in which it can disperse and so avoid that concentration which proved the undoing of the Toolache and Forrester. It is exceedingly hardy and adaptive, and if there were sufficient local senti- ment in its favour to insure the enforcement of existing regulations, it might con- tinue to occupy its present status almost indefinitely. As matters stand, however, its future status is by no means assured, and the gradual increase of rural popula- tions and the subdividing and fencing of the poorer country will undoubtedly destroy the present equilibrium and lead to its ultimate extinction. In captivity it does remarkably well, and could be established in sanctuaries without difficulty. EXTERNAL CHARACTERS, The only previous work on the South Australian representative of M. ruficollis typicus is that of I. Wood Jones (2) who, however was unable to deal with external characters de novo, owing to lack of material, the species heing at that time unrepresented in the local Museum, This lack has now been rectified, and an adequate scries, both of fresh material and of skins and skulls from all parts of its range in the State, has been available for examination. A close comparison of 15 typical South Australian examples, with material from Victoria, New South Wales, and South Queensland, has brought to light no differences so considerable or so constant as to indicate the existence here of a sub-species or definite geographical race. Hence, as the animal in the Eastern States has been the subject of frequent notice in the older literature, an extended description of its external characters along conventional lines is unnecessary. Existing descriptions of this, as of so many other marsupials, have been influenced by the curious obsession which ascribes to the pelage an overwhelming (2) Although probably several thousands are killed annually, very few age publicly marketed in this State. A few are sold in Melbourne, but the greater number are used locally by amateur rug-makers. 51 importance in description, and in reviewing and amplifying some points in these descriptions, an opportunity is taken of introducing the results of field observations and flesh measurements. These, while admittedly of little assistance in museum identifications, would seem to have some place in describing a mammal, as distinct from a skin. In the present genus, where species are so closely related, they would appear also to afford the chief avenue of approach to an understanding of their mutual relationships and the nature and purpose of their specializations. M. ruficollis typicus has been stated (3) to be the largest of the wallabies, but I find that the average linear dimensions of aged males, both here and in Victoria and New South Wales, are considerably exceeded by males of parryi and agilis. In weight, however, it is the equal of these two species, but falls short of that of the very massively built ualabatus typicus. The disparity in the size of the sexes is marked (Table I.). In general build it has been said to be slender and graceful, and this is true insofar as it can be applied to most wallabies, but in considering the sub-genus, as a whole, it is plain that ruficollis forms, in this regard, a connecting link between two natural groups—agilis and ualabatus, on the one hand—both stoutly built, thick-limbed forms, which are ordinarily given to rather deliberate movement in a habitat which is frequently swampy ; and, on the other hand, irma, grevyi, parryt, and dorsalis, in which the form is slim and attenuated, and the movements swift and free. Its limbs are relatively short and stout, and this with a short neck and well- developed forequarters, give it a decidedly compact and sturdy appearance. When seen moving in the open, its carriage appears low and its bearing care- less. The head is held very low, almost on a level with the base of the tail, and the back is thus strongly arched (pl. ii., fig. 1). The tail is convex to the ground surface, though less so than in the kangaroos, and at each stride it makes a swing- ing movement in vertical plane. Its hops are short and relatively high, and this, with the rounded back and long curved tail, imparts a curious bobbing charac- teristic to its progression, totally different from the free, long stride of the Toolache. The head (pl. i.) is large, with a deep, blunt muzzle abruptly truncated at the rhinarium and making, in this respect, some approach to the exaggerated condition present in M. greyi. Although its detailed chatacters and measurements are fairly constant, the facial expression varies greatly with age and sex. In females, the profile of the muzzle between the rhinarium and eye is markedly concave; in! males, straight or even slightly convex, The eyes are large, very dark brown and heavily fringed with lashes; but the facial vibrissae generally are but moderately developed. The ears are thicker and more fleshy than in the other species. They are very bluntly rounded at the tip, and their margins form an even continuous curve, unbroken by any notching on cither side. The innet naked portions of the conch are yellowish-pink. The ears of the female are relatively longer than in the male, and in both sexes they are shorter, in proportion to general bodily size, than in all other species, except walabatus typicus, In both sexes the arms are rather strongly developed in both segments, and the hands are large and strongly clawed; although, as is usual, these features are much accentuated in the male. The power of grasp is strongly developed, and in the use of its hands it is more versatile than many other wallabies, In feeding, for example, leaves and branchlets are not seized directly in the teeth, but are first 52 taken in the hand and either broken off or drawn towards the mouth. When on the move the arms are loosely pendant from the shoulders (pl. ii, fig. 1)—the hands are thus brought close to the ground, and are frequently brought into play in changing direction and in avoiding obstacles. In the relative development of the toes, and in the structure of the foot, there is a general uniformity amongst the brush wallabies, but the size of the pes shows considerable specific variation. In ruficollis typicus the pes is comparatively smal] and delicate for so large and heavy a wallaby, and in adults of both sexes is exceeded in length and stoutness by that of parryi and agilis, The foot length of males is about equal to that of walabalus typicus, but the foot as a whole is very much smaller and weaker, adaptations to semi-swampy conditiotis having developed in that species the broadest foot in the genus. The sole is broadly naked through- out its length and shows little of the narrowing as it approaches the interdigital pad, characteristic of wma and greyi. The nails of both tourth and fiith toes are large and strong, and at least im the district under consideration, are commonly sharply pointed. The tail is very long and slender, It is always longer (both absolutely and relatively) in adult males than in females, and in both sexes is longer than the head and body. When compared with other species, its absolute length is exceeded only by parryi, but the ratio tail: head and body is higher in irma than in either, the values being: irma, 1°36; parryi, 1°34; and ruficollis, 1°27. The basal thickening is moderate, and beyond it the tail retains its thickness almost unchanged for the proximal two-thirds of its length, the distal one-third tapering rapidly to the tip. A conspicuous character of the tail is its marked lateral compression. At the mid-point of its length, the vertical diameter commonly exceeds the transverse by 50 per cent. Small callosities are somctimes developed on the ventral surface, usually corresponding to the site of chevron bones, but a more constant feature is a sparsely-furred or even naked calloused patch on the upper surface of the base of the tail. It varies in size and conspicuousness, and is apparently formed as a result of the curious habit which many of the macropods have of resting in a squatting position with the tail pulled forward between the legs, the dorsal surface of the thickened part of the tail being then in contact with the ground and subject to considerable pressure. Although the examples examined, both South Australian and Eastern, agree fairly well with existing descriptions, there are minor points of divergence which may be noticed. The face markings have been said to be inconspicuous. ‘Chey are certainly much less prominent than in irma, parry, and greyi, but a check stripe is always plainly to be seen, and is frequently well marked (pl. i.). ‘Lhe inner aspect of the hind limb, along the whole length of the tibia and mctatarsus, is clothed with short, soft, white fur, which is abruptly and strongly contrasted with the grcy or rufous grey of its outer surface, and in flat skins especially this constitutes a prominent marking. he dark brown or black toes are also abruptly contrasted with the while foot, This is a constant feature in South Australian specimens, but is frequently still more marked in animals from southern New South Wales, where the line of demarkation is as abrupt-as in ima. The tail in South Australian specimens is short-haired throughout. There is a slight lengthening and darkening towards the tip, but the black dorsal crest, 53 containing hairs 30-40 mm. long, frequently seen in New South Wales animals, is never developed here. The seasonal change in the pelage‘® is marked, and produces greater colour changes in the coat than in any other large wallaby. In the mid-summer coat the dorsal aspect becomes a light silvery grey, and the rufous suffusion fades to a pale yellowish ochre on the neck and forequarters and almost disappears from the rump region. The hairs of the mid-dorsal region are about 30 mm. long, and are telatively coarse and harsh to the touch. With the advent of the cold weather, two distinct changes take place. There is first a great development of rufous under-fur over the whole dorsal and lateral surface, which increases the softness and density of the coat and restores the bright red colouration of the forequarters and neck. At this time, also, rufous areas are developed on the face and crown of head, which are grey in summer; and the backs of the ears, which were then black in their distal half, now become much paler and more heavily clothed. : The shade of red which is exhibited by the under-fur varies in different individuals, and in different parts of the same individuals, from Ridgway’s “orange rufous” to “Sandford brown.” It is usually most brilliant round the lower lumbar region and base of tail where, however, it is less conspicuous than on the shoulders owing to the development of longer, darker hairs. The long hairs of the dorsal region are of two kinds: the more numerous and shorter possess a broad, pure white subterminal band, while the others are much longer (50-55 mm.) and black throughout their length. The shorter-banded hairs largely determine the prevailing tone of the summer pelage, but by mid- winter the long black hairs are developed in such numbers that the whole dorsal coat loses its silvery appearance and becomes a much more sombre, coarsely grizzled grey, The ventral surface undergoes little scasonal change, but is clothed through- out the year with long, fine hairs, silvery while at the tip, dark grey or even black at the base. The pouch area in the female, and the scrotal area in the male, are tringed by hairs which are pure white throughout, In mid-winter the hairs of the lower ventral surface attain 80 mm. in length. The young, on leaving the pouch, have a short, smooth coat, totally unlike that of the adults, both in colour and texture. The fur is a very fine, soft down of a curious olive shade, the dorsal surface varying from Ridgway’s “olive-brown” to “wood-brown.” The tail is much darker on its upper surface than in adults, and both hip and check stripes are more marked. In the adult the hair tracts of the dorsum are uniformly caudad, except for an occipital reversal, which is centred between the ears, and which produces a well- marked coronal crest. The condition on the ventral surface is more complex. The main centres of distribution appear to lie in or near the armpits from which the hairs are directed inwards to the chest, forming in the mid-line a prominent opposed ridge, down- wards, to form the main caudad ventral tract, and upwards, to form a strongly- marked gular reversal which is opposed to the caudad directed mental area. (3) The degree of seasonal change varies, and this is responsible for considerable individual differences in ‘coat colour, but no mainland example which I have examined makes any close approach to M. ruficollis bennetti, of Tasmania. The habitat of the variety bennetti is stated by Thomas (3) to extend to Victoria, but this is almost certainly an error. Skins from the most southerly points of the Victorian mainland, ¢.g., the Otway Peninsula and Wilson’s Pro- montory, are not darker than average South Australian specimens. 54 On the lower part of the belly the condition varies. In the male the scrotum is always the site of a radiation which may give rise to a reversal reaching as far as the xiphisternum, but which is usually much less in extent. In the female there is usually a very well-marked ridge of opposed hairs occupying the mid-line between the cloaca and the lower margin of the pouch, which is probably sig- nificant in directing the newly-born embryo upwards towards the mammary areas. Minor reversals are present on the inner aspect of the limbs. CRraNIAL CILARACTERS. A series of 20 sexed skulls from measured individuals, representing a wide range of developmental stages, has been examined. The proportions of the adult skull as exemplified by the conventional measurc- ments are, for the most part, in close agreement, and its main outlines and con- tours fairly uniform, Especially characteristic, though not absolutely constant, are its small transzygomatic breadth, its short globular brain case, and the large projecting premaxillary spine. In the size and shape of its individual bones, however, and in matty minor details of structure, the skull of ruficollis is very variable, and such features as provide fairly reliable criteria of identity in the other species are very misleading in this. An element of uncertainty is thus introduced into identifications based on cranial characters alone, and in particular aged examples of M. parryi, and the present specics may easily be confounded. The nasal bones are particularly variable and simulate in their differing phases, shapes which are normal in every other species. Their posterior expan- sion varies to such an extent that the ratio, length: posterior width, may be as low as 2°12 and as high as 3:05. The naso-frontal suture may be almost strictly transverse, as in billardieri, or may deeply invade the frontals as in agilis. Similar differences are met with in the inter-temporal region, which in skulls at similar stages of dentition exhibit very different degrees of constriction, the shape of the frontal area being correspondingly modified. The supra-orbital edges are stated by Thomas (3) not to develop post-orbital processes, but four of the mule skulls, the measurements of which are given, do so to a degree which [ cannot match in a series of 14 parryi skulls, where that condition is supposed to be characteristic. Four main palatal vacuities are nearly always present, arranged in two pairs on either side of the mid-line. In each pair the anterior gap is about twice as large as the posterior, which is situated nearer the mid-line and is separated from its fellow by a narrow oblique septum. ‘The pattern thus produced is fairly con- stant and is not closely approached by any other wallaby of the same size. It is in the dentition, however, that the skull exhibits its greatest pecultarity. The upper incisors, especially I.*, are excessively large ‘4? and powerful, actually exceeding in this respect some of the kangaroos, and being relatively the largest premaxillary teeth in the whole genus. On the other hand, the permanent premolar is small, and if the teeth have not been profoundly modified by wear, this combination of large incisors with a small P4 serves at once to distinguish ruficollis from all its congeners. (4) Their maximum dimensions, however, are only observed in very immature skulls, as the rate of attrition is very high, and by the time P4 has irrupted, the vertical diameters of all three have been much reduced. 55 Tasie I, Dimensions of M. ruficollis typicus (in m.m.).

By Epwin Asupy, F.L.S., M.B.O.U., and Bernarp C. Cotton, Assistant Conchologist, South Australian Museum. [Read November 14, 1929] No. I. The Genera CaLLocuiton, Eupoxocnrron and Eupoxopiax discussed. INTRODUCTION, E. Ashby (Proc. Mal. Soc. Lond., xviii., pt. 2, p. 89, 1928), without having seen an example, listed Callochiton castaneous Wood, as Eudoxechiton because its coloured figures so closely resembled Eudoxoplax inornatus Ten. Woods. Iredale and May, in proposing the genus Eudoxoplax for the reception of Chiton tmornatus Ten. Woods (Proc. Mal. Soc. Lond., xii., pt. 2 and 3, p. 99, 1916), found “it to differ appreciably from Callechiton and approach very closely toy Eudoxochiton, . . . and may later be regarded as a subgenus of Eudoxo- chiton.” Discussion. Careful examination of Callochiton platessa Gould, C. castaneus Wood, Eudoxoplax inornata Ten. Woods, and Eudoxochiton nobilis Gray, warrants the | following conclusions :— (1) The radulae of the four species show no generic difference. (2) The sculpture of the tegmentum is similar (but for some minor varia- tion in the granulation), and under 65 magnification all show the same minute striated pattern. (3) The general shape of the valves, and also the sutural laminae, are similar. (4) The latter are joined across the middle line by a forward extension of the articulamentum. (5) The insertion plates in all valves are “multi-slit and propped.” (6) The girdle, in juveniles, is clothed with closcly packed “needle scales.” All are consistent characters of the genus Callachiton. DIFFERENCES. (a) In Ludoxochiton nobilis Gray, the “needle-scales” are slightly more irregularly placed, broader and stouter (characters which alone are of only specific difference). The girdle, however, has also large, hollow, flat-sided, grooved, dark coloured spicules, apparently deep seated; characters which in combination with the above may be of generic significance. (b) In Eudoxoplax inornata the slittings in all valves are more numerous, and the propping is more strongly marked, giving the teeth a serrate appearance; a difference, not in character, but merely in degree of sculpture. (c) In Eudoxochiton nobilis besides their increased slitting, the teeth are _ also laminate, the spongy character of the eaves extending between the laminae. Cc 58 We consider Eudoxochiton a valid genus, because of its peculiar laminate and spongy teeth, and the deep-seated, scattered spines in the girdle armature. The three species, inornata, castaneus and platessa, are Callochitons, and the first two may be regarded as representing the section Trachyradsia Dall of this genus. Pilsbry (Man. Conch. xiv., p. 52, 1892) places C. castaneus Wood in the subgenus Stereochiton (Carpenter M. 5S., Dall, Proc. U.S. Natl. Mus., p. 286, 1882), type C. castaneus, distinguished by the great extension of the girdle and absence of girdle scales in the adult form. Pilsbry, p. 83 (Lc.), treats Trachy- radsia (Carpenter M. S. Dall, Lc., p. 323, 1878) as a section of Ischnochiton; but (Man. Conch. xv., p. 68, 1893) as a subgenus of Callochiton (dating from 1878) with C. fulgetrum as type. Ile places Stereochiton Dall, 1882, as a synonym, to which we now add Eudoxoplax. Note.—Sykes (Proc. Mal. Soc. Lon., i., pt. 3, pp. 32-136, 1894), considered C. fulgetrum R. V., as a syn. of C. castaneus Wood. No. IL. A species of CaLListocHiton new to South Australia. Callistochiton mawlei Iredale and May was until recently known only from South East Tasmania, but was later recorded from Portland, Victoria (Victorian Naturalist, xliii., p. 357, 1927), and Ashby has since collected four examples at -Cape Northumberland, South Australia. No. III. LEPIDOPLEURUS MATHEWSIANUS Bednall and its synonymy. Lepidopleurus mathewsianus was described as of Bednall in a conjoint paper by W. T. Bednall and E. H. V. Mathews (Proc. Mal. Soc. Lond., v., pt. 2, 1906). ‘As the single example found by Mathews (said to come from Gulf St. Vincent) was lost, specimens from Marino in the same gulf, regarded as conspecific, were supplied by Ashby, so that Marino may be regarded as the type locality. We find that L. niger Torr (Trans. Roy. Soc. S. Austr., xxxv., p. 105, 1911) from Hope- toun, Western Australia, is conspecific, having compared the holotype of Torr’s species (kindly lent by him) with the tototypes of L. mathewsianus. L. niger was described as “much broader in proportion to its length” than L. mathewsianus. This was due to the fact that the head valve was absent from the type specimen, as is manifest in the illustration (Trans. Roy. Soé. S. Austr., xxxv., pl. xxv., fig. 5a.). Terenochiton erratus Hull (Austr. Zool., xli., p. 159, 1923), from King George Sound, Western Australia, should also be added to the synonymy. The paratype (kindly lent by Basset Hull) is white, whereas most of the examples from Marino, S.A.,, are dirty white or buff coloured. South Australian specimens show a wide variation in the shape of the posterior slope of the tail valve. In T. erratus this is steeper than most specimens of L. mathewsianus found in South Australia, but some examples from Marino and Port Lincoln are like the Western Australian specimen. We compared Lepidopleurus glauwerti Ashby and L. badius Hedley and Hull with L. mathewsianus, and with each other, and consider them both distinct species. 59 ADDITIONS TO THE FLORA OF SOUTH AUSTRALIA. No. 28. By J. M. Brack. [Read April 10, 1930. ] PuaTe IV. GRAMINEAE. Triodia longiceps, nov. sp. Gramen rigidum glabrum pallidum, plus quam metrale ; folia longa, subulata, apice pungentia ; ligula brevissima, ptbescens ; catilis nodi pauci, puberuli; panicula angustissima, 25-50 cm. longa, ramis in- ferioribus erectis, 5-10-spiculatis; spiculae angustae, primum lineares, 9-20 mm. longae, 9-21-florae; glumae vacuac glabraec, 4-5 mm. longae, apice acutae vel emarginatae, nervo mediano solo conspicuo; glumae floriferae circiter 4 mm. longae, apice in 2 lobos, minutos obtusos et mucronem medianum breviorem desinentes, ad basin annulo pilorum cinctae, ceterum fere glabrae; palea margines glumae floriferae paululum excedens. Finke Gorge, Hermannsberg, Central Australia; coll. J. B. Cleland. Local name, “Bush Spinifex.” Differs from T. irritans in the longer, narrower spikelets with more numerous flowers, the shorter l-nerved outer glumes, the glabrous flowering glume with a ring of erect hairs round its base, and the much longer panicle. When in flower the spikelet is barely 3 mm. broad and linear in shape; the small membranous wings of the palea slightly excced the edges of the flower- ing glume, so that they appear more conspicuous than in other Triodias. The new species is perhaps confined to Central Australia. ( Plate iv., figs. 5-8.) Bromus macrostachys Desf. This Mediterranean grass, conspicuous by its twisted and divaricate awns, has been found growing on waste land near the Waite Agricultural Research Institute, Glen Osmond. PROTEACEAE, Hakea ulicina R. Br., nov. var. latifolia. Folia plana, oblongo-cuneata, 3-18 cm. longa, 4-13 mm. lata, pungenti-mucronata, 3-nervia, interdum nervis tenuioribus intermediis instructa, ita ut 5-7-nervia videantur. Ninety-Mile Desert, near the Coorong; coll. E. Ashby. The broader leaves, prominently 3-nerved, and sometimes with additional fainter intermediate longi- tudinal nerves, bring this form near H. dactyloides Cav., a species inhabiting eastern New South Wales and Gippsland, but the pedicels of our variety are always, as in the type, quite glabrous. The fruit is sometimes 25 mm. long. LEGUMINOSAE. Acacia lineata A. Cunn. This slender, viscid shrub appears to be fairly common in the Murray scrub near Karoonda. The linear phyllodia have a pro- minent nerve on each face close to the upper margin, and the lower margin is also thickened and nerve-like, leaving a narrow, flat channel between the two longi- tudinal ridges. The real nerves (as will be seen from fig. 4 of the accompanying plate) are three—two opposite the upper margin and one opposite the lower margin—all concealed within the hardened cellular tissue of the phyllode. Our specimens, from Karoonda, agree perfectly with some from Dubbo, New South 60 Wales, The form found near Port Lincoln and Tumby Bay has but one nerve, which is removed from the upper margin so as to be almost central, and the lower margin having no prominent nerve there is no longitudinal channel. This plant was considered by Bentham to be merely a form of A. lineata, but Mucller raised it to specific rank as A. imbricata, probably because the crowded, almost erect phyllodes have an imbricate appearance. Maiden took the same view, which is perhaps the correct one, but unfortunately our specimens from Eyre Peninsula are few and imperfect. It is worthy of note, however, that the illustration in the Botanical Magazine of the type from New South Wales shows some of the phyllodes as having the nerve almost central. (Plate iv., figs. 1-4.) Swainsona dictyocarpa, nov. sp. Planta parvula (speciminibus nostris 3-6 cm. altis), glabra absque paucissimis pilis sparsis appressis basifixis; foliola 3-7, ovato-oblonga, 5-12 mm. longa, 3-4 mm. lata, supremum inferioribus aliquanto longius; stipulae parvae, lanceolatae; racemi 2-6-flori, foliis longiores; pedicelli 2 mm. longi, minute puberuli, duplo longiores quam bractea scariosa ciliolata ; flores (siccati) caerulei; calyx 5-6 mm. longus, dentibus lanceolatis intus puberulis, tubo glabro paulo longioribus ; bracteolae minutac, subulatae; vexillum citciter 12 mm. longum latumque, levissime bicallosum ; carina obtusa, sine sacculis, alas subaequans; ovarium glabrum; stylus fere tota longitudine barbatus, apicem. versus rectus; legumen immaturum turgidum, subcylindratum, 12 mm. longum, 5 mm. crassum, glabrum, valde reticulatum, secus suturam haud impressum. Bitter Well, Coondambo (north of Lake Gairdner), October 29, 1929; coll. J. B. Cleland, Differs from S. viridis in the leaflets less cuneate in the lower part and narrower towards the summit, the stipules narrow and scarious, instead of broad and green, the bracts scarious and only half as long as the pedicels, instead of green and as long as they; the wings as long as the keel or a little longer, instead of shorter, the ovary glabrous and the pod ‘shorter, thicker, much more pro- minently reticulate and not impressed along the suture. Differs from S. oltgo- phylla in its almost glabrous character, the narrower stipules, the calyx with much shorter teeth and without hairy longitudinal nerves, and in the glabrous ovary and glabrous reticulate pod. From both it differs in the terminal leaflet longer than the lateral ones. : Swainsona canescens (Benth.) F. v. M. Specimens collected by Professor Cleland on Coondambo Station have the calyx 9 mm. long, of which the acuminate teeth occupy almost 6 mm. The standard appears to have always a greenish blotch at base, as mentioned by Bentham in connection with his Western Australian specimens, and the keel has always the two characteristic rounded calli at the tip. . Tephrosia sphaerospora F. vy, M, has been found by Professor Cleland on Andamooka Station, west of Lake Torrens, Ilitherto it has only been known from the country north of Cooper’s Creek. Trifolium Bocconet Savi. Inman Valley, Balhannah, Penola; November, 1929. A new record for our State, This clover is a native of southern Europe, extending as far north as the Cornish coast. Trigonella ornithopodioides (L.) DC. Kalangadoo and Penola; coll. E. S. Alcock, November, 1929. This European clover-like plant occurs in pasture, and Mr. Alcock describes it as useful feed. It has also been collected at Blackwood, and was recorded in Victoria several years ago. ZYGOPHYLLACEAE, Zygophyllum fruticulosum DC. nov. var. brevilobum, Variat foliis linearibus, 14-2 cm. longis, ad apicem brevissime et obtuse bilobatis, ita ut folia emarginata simulent ; sepalis lanceolatis, 5 mm. longis petala lutea obovata subaequantibus. 61. Seventeen miles north of Tarcoola, October 30, 1929; coll. J. B. Cleland. Has a very distinct appearance owing to the rather long linear leaves, which appear notched at summit, owing to the two very short, obtuse lobes. The small flowers are near those of var. eremaeum, but the sepals are very acute and the petals obovate and obtuse. One capsule had attained 8 mm. in length, but was still unripe. ELATINACEAE. Bergia perennis F. v. M. McDouall Peak Station, south of Stuart Range; coll. J. B. Cleland, October 31, 1929. This little woody plant is new for South Australia proper, but was recorded by Tate in the report of the Horn Expedition (published 1896) as having been found by Kempe at Hermannsberg and by Tietkens at Mount Sonder, both in the MacDonnell Ranges, Central Australia. It was first collected by Mueller on Sturt’s Creek, North Australia, in 1856. The short stems of our specimens appear to be prostrate. This species differs from B. trimera in its perennial character, solitary axillary flowers, 5 sepals and petals, 10 stamens, shorter obtuse leaves, scarious stipules with long cilia and five styles and capsule-valves. MYRTACEAE, Darwinia micropetala has been found recently by Mr. E. Ashby at Salt Creek, Coorong. COMPOSITAE. Centaurea repens L. A troublesome weed in vineyards along the Murray. The heads are spineless, but the plant is perennial, with creeping roots. It is a native of Central Russia, Asia Minor, and Persia, and was recorded in Victoria in 1907, but has only been found recently in our State. A synonym is C. Picris, Pallas. .

No. 6—PHYSIOLOGY AND MENTAL OBSERVATIONS ON THE AUSTRALIAN ABORIGINES. By R. PuLterne and H. Wootvarp. [April 10, 1930.] INTRODUCTION, The remarks which follow are to be regarded as a preliminary attempt to assess quantitatively, if possible, the sensory acuity and the inborn ability of the aborigine. Notwithstanding his reputation of being able to see the tracks of man and animals where the unpractised white man can see nothing, the investigations of Rivers, McDougall, and others on the sensory acuity of primitive peoples render it improbable that this and similar ability depend on any inherent superiority of the organs of special sense. The estimates of his intelligence which have currency at the moment are impressions and have only that validity which the experience and care of the observer commands. In a recent book on the Australian Bush the author describes the aborigines as rude, backward, unintelligent, unable to learn civilized arts; their beliefs are crude; their practices are repulsive; their corroborees ugly and indecent. A reviewer dealing with the above book by Miss Fullerton quotes the follow- ing from Dr. Ramsay Smith:—‘“Children in school can be educated like white children and to the same extent. . . . Some speak English chastely and beautifully. Some train themselves in music. Some show great mechanical ingenuity and read and understand books on mechanics and physics. . To anyone who knows how the blackfellow, even in a single lifetime, reacts to new influences, moral, intellectual, and mechanical, the facts seen to upset all theories of cranial capacity, cerebral functioning, and mental operations.” It is obvious that a just estimate of the ability of the aborigine can only be obtained by some kind of measurement properly applied over a wide enough field. We believe the time has arrived when something of the sort can be attempted. It has been repeated again and again that the aborigines of Australia repre- sent the most primitive variety of man still existing. This may be true, but it is hard to find the basis for such a sweeping assertion. Writers who make this statement have in mind, most probably, his failure to discover any kind of agricul- ture, and his inability to make any provision for the future. This latter is all the more surprising, for the nature of his environment demands such provision. The number of aborigines in the country when it was first settled will never be certainly known, but estimates rarely exceed 150,000—a biological index which indicates a failure to gain any control over the environment. However, it is not our purpose to deal with the cultural aspects of the aborigine, but it might not be amiss to point out that it has long been a commonplace that complex civilizations owe much, if not all, to the migration and diffusion of culture. Elliot Smith and Perry have collected abundant evidence to show that the same is true in a large measure of primitive cultures also, The backwardness of the aborigine may be due to his “splendid isolation,” which has been complete for thousands of years. 63 If we glance for a moment at those aspects of the aborigine which are nearer to our own purposes, we find the basis of the above assertion, that he is so very primitive, equally dubious. Physical anthropology would regard a race as primi- tive if it showed many characters that indicated affinity with fossil man, ¢.g., Neanderthal, or Pithecanthropus erectus, or even with the great apes. Huxley long ago suggested that there was a special resemblance between the Australian aborigine and the skull of Neanderthal man. Recent work, such as that of Berry, and especially Morant, has shown that there is no evidence for this statement. The aborigine is only one among a number of primitive races, and is by no means the most primitive of these. Detailed dissections of his body, and in particular of his face, feet, and hands, have failed to reveal any particular kinship with fossil or anthropoid forms. The central nervous system might be expected to throw particular light on this problem. Elsewhere one of the authors has published a systematic account of the brain. Suffice it here to say that the brain is small, has frequently a sulcus which appears rarely in the European brain, but the general fissuration and the development of the areas underlying the higher mental pro- cesses show some excess in the visual area and some deficiency in the temporal region. Though phylogenetically the size of the brain and the complexity of animal behaviour go hand in hand, yet it remains a fact that many investigations made on different varieties of men have failed to show any correlation between the size of the head and intelligence. For instance, a square head is of the shape to give a greater cranial content than a long head, yet measurement and experience have failed to show any differences in ability. Thus it appears that if we wish to find further support for the idea that the aborigine is the most primitive of existing races, some further tests must be applied. MENTAL MEASUREMENT, For the measurement of the acuity of the various sense organs, methods have been evolved which are now almost traditional. No discussion of these is needed at this place. It will suffice to mention our procedures in the appropriate section. For the measurement of the intelligence we have the various systems of intelli- gence tests. Despite the vast amount of work done with these tests and the experience that has been gained, it cannot yet be said that they are thoroughly established. Opinion varies from whole-hearted acceptance to the assertion that no one knows what intelligence is, and therefore, no one can know what tests measure it and what tests don’t, An essay such as this cannot attempt any critical summary of the value and the limitations of such a method of enquiry. Two considerations justify the use of such intelligence tests for our present purposes. In the first place, there is no other method which pretends to give a quantitative measure of ability as distinct from the effects of training and education. In the second place, if we were to wait until every objection had been met, stich time might elapse that this dwindling people might have disappeared altogether. It is desirable, not only on scientific grounds, but also from practical reasons, to attempt to measure the ability of these people. For ourselves, we are persuaded of the essential rightness of the present theory of intelligence formulated by the English school of psychology—a school objective and mathematical, inspired by Galton and whose present most brilliant exponent is Spearman. Spearman’s theory implies that intelligence is revealed in the solution of problems, the ability to perceive and educe the relations between things apprehended. Tests which demand for their solution the perception and education of relations do, therefore, measure intelligence. And most so-called intelligence tests imply these things. By an analysis of the results of various 64 intelligence tests, Spearman observed that the correlations between the tests them- selves exhibited a definite order of hierarchy. This led to his now famous tetrad equation, whose principle may be briefly expressed as follows :— r( A, P ) r( A, P ) r( B, P ) r( A, Q) where A, B, P, Q represent any four capacities not obviously akin. The main significance of this hierarchy is that we are led to infer that all the functions of the human mind, the simplest and the most complicated, are probably processes within a single system. As Burt has pointed out, the contrary assumption of a radical dichotomy between the general mammalian foundation of the central nervous system and the specifically human capacity of general intelligence, proves a serious barrier to the advance of the biological standpoint of individual psychology. Spearman’s work has suggested that ability consists of two factors—a general factor G, which is innate and unaffected by environment, and specific factors S, which are more subject to training and education. General ability enters into most mental performances in some degree. Tests which depend on mere sensory discrimination do not involve much of G, Memory, in so far as it is mere repro- duction, involves no G, but the more it makes use of association the more of G enters into it. It is true that this theory of Spearman’s has been severely criticised and his mathematics have been rigorously questioned. Pearson and Moule have lodged a definite verdict of not proven on mathematical grounds. We must confess, however, that apart altogether from its mathematical basis, we find the theory most persuasive on general grounds, and, if true, it would establish the funda- mental validity of the method of intelligence tests. For any tests to work satisfactorily it is, of course, essential that the person to whom they are applied should understand them and should try to do his best. The latter qualification seems abundantly present in the aborigines, for all who have attempted any kind of investigation on these friendly and engaging people, have found them most anxious and willing to co-operate and do their best. The Binet-Simon test, as propounded by Burt in his book, forms the group of tests most widely used and for which most experience has been obtained. It would be desirable to use these. They demand, of course, some rudiments of education, and have heen adapted to children from three to fifteen years of age. It so happens that the mission school at Koonibha has assembled a group of pure-blooded aboriginal children under the charge of a schoolmaster, who has classified them and is teaching them according to the standards of our elementary schools. Thus the children form a suitable group for such an investigation. PHYSIOLOGICAL TESTS. Our enquiries amongst the aborigines of the Koonibba station followed a variety of ways. We performed a number of physiological tests; some estimate was made of sensory acuity; from the natives themselves, and from the personnel of the station we tried to obtain some idea of what they were capable of doing; _and, finally, we attempted to obtain a measure of intelligence by our own improvised methods. Our intelligence testing was merely preliminary. We hope to follow it up systematically at some future date. MEASUREMENTS OF BLoop Pressures AND PuLse RATES. These estimations were carried out on full-blooded natives by the usual instru- ments and methods. The pressures were measured while the subjects were seated 65 after they had been resting for about ten minutes, and after they had been put at ease by talking and watching other measurements being carried out. The systolic pressure was estimated by the tactile method, the diastolic by the auscultatory. The difference between these represented the pulse pressure. The results are included in the following table :-— MALES, Age. Sys. P. Dias. P, Pulse P. Pulse R. 25 108 55 53 65 25 120 && 32 74 13 118 78 40 82 30 166 110 56 96 30 138 92 46 88 20 132 102 30 68 25 102 60 42 60 25 128 90 38 68 25 128 90 38 68 30 120 80 40 76 FEMALES. 20 136 80 56 84 23 116 58 58 96 16 140 98 42 96 22 130 90 40 100 25 128 94 34 120 In addition to the results expressed in the above tables, figures were obtained for full-blooded aborigines of ages outside those limits. These have been excluded from the determination of the average because of the effect of age in altering the value of these pressures. Investigations carried out on groups of subjects such as soldiers of the British Army, University undergraduates in England and America, and other enquiries, have shown in general that the systolic and diastolic pressures are low in childhood, that they rise at puberty, and in adolescence from the seventeenth to twenty-eighth year there is a further rise. Thereafter these pressures remain constant until about the fortieth year, when another rise begins with advancing years. Throughout these various periods the product of the pulse rate and the pulse pressure tends to remain constant, the more rapid pulse compensating for the low pulse pressure of childhood. Moreover, the three measurements, systolic pres- sure, diastolic pressure, and pulse pressure tend to preserve a ratio of 3:2: 1 to one another. From all the various observations that have been made, running into many thousands and comprising different classes and ethnic groups, the commonest values for systolic pressure, diastolic pressure and pulse pressure are: S = 120, D = 80, P P = 40.. For the Australian aborigine the average for ten full-blooded males between 15 and 30 years of age is :— Systolic pressure <= Diastolic pressure = 84:5 Pulse pressure = For females of the same order the corresponding figures are :-— Systolic pressure = Diastolic pressure = 82 Pulse pressure = 66 It will be seen that these figures present no sharp differences from those obtained elsewhere, and the same ratios hold. Generally the female systolic pressure is slightly below that of the male, but the measurement of 717 Filipinos of average age of 25 years, by Conception and Bulatoa, gave 115 for the males and 116 for the females. Owing to practical difficulties, any measurement made on living pure-blooded aborigines must necessarily be confined to small numbers. It is no use lamenting this fact. One has simply to make the best of it. Ray made some measurements on Central Australian pure-blooded aborigines, He took the mean of all his subjects, irrespective of age, and for the males (44) arrived at the following figures :— Systolic pressure = 125-3 Diastolic pressure = 79:07 Pulse pressure = 46:3 For 13 females the figures were :— Systolic pressure = 116 Diastolic pressure == 73°5 Pulse pressure = 42:5 Ray remarks that these figures almost exactly coincide with the figures for healthy Europeans, but are 5-10 mm. below that for healthy white Australians. Thus we may well conclude that the aborigine exhibits no deviation in circu- latory pressures from the inhabitants of, say, England and America. This state- - ment needs two qualifications—the numbers are too small, and the computations have not been analysed in accordance with proper biometric practice. The second qualification arises out of the first. There are observations on the basal metabolism of full-blooded aborigines now available which perhaps give a little further interest to these figures. The figures obtained show the basal metabolic rate as 10% to 20% below the accepted average values. Since the basal metabolic rate is ullimately an expression of the rate of energy production of the active protoplasmic mass, it might be expected in the absence of any evidence of endocrine deficiency that this lower rate might be reflected in the values of circulatory pressures. It has already been remarked that they arc of the same order as those obtained from healthy subjects of similar age elsewhere. Read has suggested a formula which gives values for the basal metabolic rate whose error is less than 10% for 60% of the cases tested. The formula is as follows — B.M.R, = 0°683 (D.R. + 0:9 P.P.) —71°5. Applying this formula to the above figures, we get for the males examined a value for the B.M.R. = 5-5, approximately. This means that basal metabolic rate would be 5% and more above the mean basal metabolic rate. Thus we are led to a result different from the direct estimations. There is plenty of evidence that blood pressures and pulse rates are correlated with B.M.R., and, as a matter of calculation, the factor 0-683 represents the correlation co-efficient of these with the B.M.R. Apart from the inherent error of the method, the figures for pulse rate and pulse pressure do not represent real basal values. Moreover, it assumes a linear relation between pulse rate and pulse pressure which may not be true. Nevertheless, it is of interest to review the circulatory pressures and rates in relation to metabolic rates. And it is surprising that they should not both tend in the same direction. 67 AUTONOMIC REACTIONS. Adrenalin and the Sympathetic Nervous System—When adrenalin is in- stilled into the conjunctival sac of a healthy individual, no effect on the pupil is produced. In certain diseased states, however, a dilatation or mydriasis follows the application of the drug. In this way adrenalin can be used to give a measure of the excitability of the sympathetic nervous system, a quality we might expect to exhibit some variation with race. Unfortunately we discovered too late that we had brought very little adrenalin, and only three tests were carried out. These were all negative, and as far as they go it is inferred that the aborigine reacts in the same way as the white to this test. Atropine and the Vagal Autonomic Fibres——By the same reasoning, atropine can be used to bring out the activity of the vagus nerve. The vagus nerve inhibits the heart rate, but this effect can be removed by the giving of atropine which paralyses the nerve endings of the vagus in the heart. In doses of 1/,,, gr. its effect is confined to the endings of the vagus, the sympathetic nerve fibres are unaffected and there is no action in the cardiac muscle directly. When the vagal effect is removed the rate of the heart beat may remain unchanged or be increased. The effect which occurs depends on whether the vagus effect, or the vagal tone as it is called, is high or low. In dogs, for instance, the heart beat is considerably quickened, the vagal tone being high; in cats the effect is less; and in rabbits and frogs there is no change whatever. In man it has been found that the inhibitory effect of the vagus on the rate of the heart is absent in the child, gradually appears with age, reaches its maximum at about 25 to 30, and thereafter declines, In old age the increase in the number of beats may be not more than four per minute. We tested this reaction in a number of full-blooded aborigines by giving them, by mouth, */,9) grt. of atropine dissolved in water. The pulse rate was then counted at intervals of five minutes. The following results were obtained :-— MALES. P.R. after Atropine Age. Normal P.R. TY io9 BT Tner.

This is in accordance with results obtained on the general population of the community. The few results obtained for the females seem to suggest that in them the vagal tone is much less. It is to be noted that in most cases they are youger than the males, and that in each case the normal pulse rate is higher. Either there was some emotional reaction to the procedure, of which we saw no other manifesta- tions, or sympathetic tone is higher. This holds when allowance is made for age. Thus, in spite of the qualifications of the fewness of observations that must be made, there appears some reason to suppose that there is a sexual difference in the reaction to the atropine test. OPHTHALMOSCOPE EXAMINATION. Before proceeding to some sensory tests, we might record here the result of examining the fundus of the eye with the ophthalmoscope. The normal eye of the young aborigine may be described as clear, even brilliant, The eyelashes are long and silky, and the conjunctiva is unpigmented except over the bulbus oculi, where there are scattered masses of pigment. Pigment occurs along the horizontal meridian of the eye, and this seems to increase with age. The eyes of the old aborigines, owing to dust, flies, smoke, and the like, have invariably some chronic conjunctivitis which gives the eye a dirty appearance. The iris has a very uniform dark brown colour, and the pupil responds very readily to light changes. The fundus of the eye was examined at night with the ophthalmoscope, the pupils having been dilated by homatropine and cocaine. In eleven subjects the following details were noticed. The general appearance, instead of showing evidence of a marbled pigmentation, was of a dull silver or pewter colour with a white or silvery reflex to light. The optic disc was flat or slightly cupped, its margin being in part or wholly pigmented. The macula appeared in a silver fleld as a cherry red spot, and the fovea appeared like a spark in the middle of the macula. The silvery reflex of the retina spread out to the periphery, and the familiar red reflex seen in Europeans was absent or only appeared as a faint pink in one case. The vessels showed up in relief, and were entirely free from pigment along their lines of distribution. Acuiry oF HEARING. A metronome was set to a onc-second beat. It was placed on a slightly sloping bank, and all the people to be examined, along with the examincr, were placed out of hearing of the metronome. They then advanced towards the source of the sound, stopping when they heard it. ‘he distances at which each could first hear it were then measured by means of a stccl tape. There was consider- able variation in the results so obtained. he highest auditory acuity was found in a white boy, the son of the schoolmaster. Visuat ACUITY. Cohn’s “E” test was used, the size being D = 1:0 of the metric test com- monly used for testing the acuity of vision at 5 metres. This “E” was drawn on white Bristol board with Chinese ink, and a duplicate was supplied to the examinee. A card with the “E” on it was fixed on the north wall of the school- house at a height of five feet, and could be turned in the four principal directions. The illumination was constant at all tests, which were carried out between ten and eleven each morning. The subject of the test was placed at a measured distance from the test card, and was required to place the “E” on the card he carried in the same position as the one he observed, The distance was recorded 69 “when three consecutive tests were correctly performed. This and the previous method (hearing test) were practically the same as those used by Seligman in his observations. The test object, placed in a bright light, could be orientated at 24 feet by ourselves. With two exceptions, it could be properly orientated at twice this distance by the aborigines, and in one case at three times this distance. However, the farm manager and his small daughter (white) equalled the best of the aborigines. Though the average visual acuity is very high in the aborigines, it does not exceed the limits that can be reached by whites. Some Acuity TEsts. No. of Testee. Metronome.

We proposed to measure this in the ordinary way by applying compass points to the flexor surface of the forearm and measuring the minimal distance at which the two points could be discriminated. In practice we found the test very difficult to carry out. It was difficult to be sure that the subjects understood what was expected of them. Their replics were so discrepant that no rule could be estab- lished. Our results are, therefore, very imperfect. We, however, gained the very definite impression that their tactile acuity was of the same order:as for whites generally. Tue DiscrIMINATION oF CoLour, Two tests were applied. In the first the subject was asked to name or trace the figures in the Stilling test book for colour blindness. This book is so arranged that one or two figures are constructed by an appropriate arrangement of coloured dots. The figures are immersed in a background of coloured dots. The colours are so chosen that if the subject has any form of colour-blindness certain figures will be invisible to him. Conversely, certain figures are so presented that they can only be seen by a colour-blind person. The book formed an excellent test. Prac- tically the whole range of the spectrum is used as a test in discrimination. The subject can either name or trace the figures and comprehends easily what is required. Thus it could be used with quite illiterate persons. Some forty full-blooded aborigines of both sexes and widely different ages were tested by this book. In all cases the figures were identified or traced with ease, and so it can be asserted quite definitely that the aborigine is sensitive to 70 the colours of the spectrum to the same extent as ourselves, and colour blindness can only be an occasional event. No case was discovered in our 40 tests. The second method we used was the discrimination of coloured wools. Skeins of wool were chosen which comprised some twenty different shades of green, red, blue, and yellow. The method we adopted was to select one of the primary colours and then ask the subject to select from the group every skein which he thought contained the same shade of colour. A few performed the test well and chose nearly the maximal number of corresponding skeins. The white children on the station could perform the test quite easily and perfectly, In testing the aborigines difficulties arose. Some did not seem to understand clearly what was required. Some understood but would quickly desist when a few corresponding shades had been chosen. When questioned, these showed clearly that they appreciated differ- ences in shade of colour. It was an interesting and irequent observation that when a limiting hue was reached, such as a skein containing a faint trace of yellow, and the question of adding it to a group or not arose, the aborigine became greatly troubled. He would add it to the group and then take it away, and repeat this several times, and finally resign the test in despair. They behaved as though the idea of adding it or subtracting it alternately flickered in their minds, This state of indecision was accompanied by obvious signs of distress. The results obtained varied considerably, but the tests went far beyond the perceptual range and indeed represented an examination in the power of abstract- ing a general idea from a particular instance. The measure we intended to use, namely, correct performance as unity, and degrees of imperfection in performance as the fraction of which the numerator was the successes scored, and the denominator the total of possible successes, was not of much value for the reasons given above, A more just measure is given by using categories such as bad, good, and excellent, for these contain some allowance for the lack of comprehension, and so forth. Of the tests so performed eight are classed as bad. This group contains four young men (average age, 25). As above remarked, white children of cight years of age perform the test easily. Ten were classed as good, and four as excellent. That is to say, only four adult aborigines out of eighteen performed this test as well as white children. INTELLIGENCE. The tests so far recorded bring evidence that the physiological levels of the aborigine are much better or much like our own, Moreover, we have discovered so far no difference in the acuity of his various sense organs, with perhaps the exception of vision. If it is true the aborigine is the ultra-primitive variely of mankind, then we may assert at this point in our investigations the distinction does not lie in his basal physiological and psychological processes. The last test described above (the matching of colours) does seem to hint at a lower level of performance in conceptual processes. In the beginning we have discussed what was in our minds about trying to get some measure of one aspect of his mental processes, namely, intelligence, and naturally we turned to the intelligence tests. Though these tests have been applied to adults on a large scale, yet whatever reliability they possess is greater when applied to children of the appropriate ages. It may be recalled that in Burt’s book there has been recorded some remarks of Binet about objections to his methods. Some teachers who had demurred at his scheme were asked to demonstrate what methods they would use to assess intelli- gence. They proceeded to ask all kinds of questions such as common sense would 71 suggest. Binet’s comment was that they used a method the same in principle as his own except that he standardised the questions, defined the methods of putting them, valued them according to age, and tried them on a sufficient number to get rid of the error of random sampling. Since our population was a random sample and contained many adults of various ages, and some quite illiterate, we tried the so-called common-sense method. Moreover, by interrogations referring to their immediate activities we thought that many objections might be met, such as lack of interest, or experience. Finally, it was possible to corroborate our conclusions by comparing them with those arrived at by the various members of the administrative staff, The able- bodied men about the place are for the most part engaged in some way in farm work. The younger members have formed a very enthusiastic football team. The young women who are unmarried carry out various activities arising in the hostel. Cooking, dressmaking, house-keeping command their attention and industry. The boys and girls attend the school. The farm, some 4,000 acres, is under the management of a practical farmer who happens to be especially skilled, since in open competition the cleverness of his methods has brought him several silver cups. The present harvest (1928) has been a poor one. Nevertheless, the highest yield of wheat per acre in the district has been obtained from the mission farm. The farm manager is very well disposed towards the natives, and we witnessed many incidents which showed his consideration for them, and, on the other hand, their regard for him. We feel confident that his opinions on the capability of the aborigine as a farm labourer are worthy of the highest con- sideration, In general he said that the aborigines were poor labour in the sense of bringing little skill and understanding to the task. Their industry has little persistence, and a task set them must be watched until its completion, In the handling of animals, in the care of material, and the adjustment of the means to the end in the usual farm operations, they cannot be left to themselves, In all his experience the farm manager said he knew of only one native, and he was a half-caste, who might have been competent to farm on the share system with any prospect of success, The schoolmaster was of the opinion that the aboriginal child exhibited a fair degree of competence in mastering and producing that sort of learning in which the exercise of the memory was the most important factor. However, subjects, and in particular arithmetic, where progress depended far more on the ability to solve problems, they were very slow and, in fact, never proceeded far. The matron of the hostel, a most kindly lady, had never seen a native girl who was able to cut out a dress from a pattern, though many of them sewed quite well, Their standards in dress and colour, judged by the standards they tried to imitate, remained very rudimentary. In cooking, by constant practice, they achieved a fair measure of success, as in baking bread, for instance, but any kind of planning or provision beyond the immediate object seemed never to occur. The constant preoccupation of the matron was what the girls would do after the age of puberty. No amount of teaching ever made her feel sure that these girls would remain chaste for long. It is difficult to decide whether “taking to the bush with the men” is due to the strength of their feelings, or their feeble self-control, or their lack of comprehension of any other standard. The Opinion seemed to be that their conduct was due to the first and the last of these suppositions. Evidence from Games —The football team drawn from the mission station is keen, skilful, and often successful. In addition to their skill, the other feature which has impressed impartial observers is the excellent team spirit, We were assured, and our own observation of one match substantiated this testimony, that the members of this team played so that thcir side might win, and each player 72 would sacrifice an opportunity of individual distinction in the interests of the team. Attempts to tamper with their loyalty to the team have been made, we were told, but they have been invariably unsuccessful. Along with these admirable qualities, there exists the quaint but interesting fact that the players don their football costumes at the beginning of the season and never take them off until the season is over. Group Tests—We shall now describe a few group tests. We think games provide one kind of test of what we are trying to get at, the ability of aborigines, because the aborigine is fond of games and plays them with keenness. ‘They did form part of his own civilization, throwing the kookara, for instance. One simple gatne we played with them was passing the peg. Two rows, one of aborigines and one of white, were formed, and each row passed a peg from individual to individual. The game was won by the row which passed it the faster. This game is played very often at the hostel by natives in the station. The whites won the game for this reason. Though we had never played it before, it was imme- diately apparent that if we watched our immediate neighbour so that our eyes were on the peg, and if each did this we conformed to the fundamental principle of all games, viz.; “keep your eye on the ball.” The aborigines had not discovered this, for they turned to pass the peg and thus kept losing sight of it. Another group test used was to arrange three rows of candles, one behind the other, each row containing seven candles. The object was to light as many candles as possible with one match. Obviously the angle at which the match is held will be a factor determining the rate at which the wood is consumed, And again, if the back row is lighted first the succeeding rows can be lighted without the hand being scorched. Repeated attempts failed to bring home to the native contestants either of these points, and their performance in the best cases was less than half that usually achieved at childrens’ parties. (The highest three scores of aboriginal girls averaged six. ITifteen is a common score at a party.) We were present at a reading of the Scriptures and an examination of the young men and women in the instruction they had received from the pastor in the previous week. They might be said to read, but none managed it with any case or feeling, and their rendering was monotonous and, we infer, without much understanding of the passages involved. One other test we participated in along with the aborigines. The test might be ranked as a scientific one, except that certain elements should have been morc rigidly guarded. The test consisted of the exhibition of thirty common articles, e.g., bottle, cork, corkscrew, and so on. Each article was held up so that all could plainly see it for about five seconds, and then covered up. When the series had been exhibited in this way, we were all required to write down the names of as many articles as we could remember. The highest score was 26 obtained by a half-caste, Several girls scored 20 to 23, The scientific expedition averaged about 19, and one of their members, with 8, got the booby prize. ‘his test, we consider, is largely one of reproduction, and ability only comes in when one arranges a classification of the articles in one’s mind as one sees them held up. Practice would facilitate the introduction of the associative element, Our sub- sequent enquiries led us to infer that the aborigines relied entirely on memory, and the test is of interest in that it confirms the opinion that the power of memory amongst the aborigines would be of the same average order as amongst ourselves. Our Own Interrogations——We now present a few illustrative cases of our interrogations. A female aborigine, aged eighteen, had been educated at the mission station and had reached the third grade of the school, These grades correspond to the numbers in the State elementary schools. She had ceased to 73 attend the school two years ago. She can describe the process of baking bread and can give a very good account of the procedure carried out when preparing yeast. When asked how she would prepare a rabbit for eating, she replied that she would fry it. She has some knowledge of geography and can say in general where Japan is, and how you would proceed if you wished to go to Melbourne or to the city of Adelaide. She does not know the simple arithmetical tables and cannot tell how many shillings go to the pound. In the candle test she averaged less than eight candles in three successive tests. In the memory test, reproducing the names of the articles shown, she scored 19, which was very good. The girl was among the more intelligent, Others who had been as long in the school were unable to recite the alphabet or to give the succession of numbers from twenty onwards. Any arithmetical problem, such as the value of twelve articles when one cost threepence, none of them succeeded in solving. The meaning of words such as religion, present, gift, moment, etc., they were unable to explain. An aboriginal male aged 25 reached the fifth grade of the school and was considered a very good pupil. At the selection of the coloured wools he per- formed moderately, getting less than half the skeins of the corresponding colour. On the farm he has tried to learn to shear, but has not become even tolerably proficient. He has learnt no trade. His work is ploughing, but he does not know how many acres a day he can plough (some were able to tell us this). He does not know what becomes of the wheat when harvested. He does not know the meaning of the word bushel, and can give no idea of how much wheat there is in a bushel, He has no idea of the monetary value of wheat. He can recognise on the map such countries as England, but can suggest no reason why wheat should be sent to England. He can give no reason why some countries are hot and some cold, etc. This is a fairly typical investigation. Such an aborigine, though employed daily on the farm, will assure one that he knows superphosphate, but has no idea what it is used for. We found that practically none of them had what might be called “money sense.” Calculations of the order of one article costs threepence, how much would twelve cost? were too difficult for them. Arithmetic, even of the most elementary kind, does seem to present them with very great difficulty. A group of six girls, all of them either attending the school or just left the school, were examined on the multiplication tables. Only one attempted the twelve times table, and she made several mistakes in the attempt. To two young men who had attended the mission school and who were enthusiastic and skilled members of the football team, the problem was put: If one side scores seven goals and the other scores six goals six points, what would be the result? They were extremely puzzled and tried hard to find the answer. Each picked up a pencil and paper and tried to get an answer. It was clear they had the relevant information and even some idea of how an answer might be got, but they were unable to get the correct result. When the problem was explained, they seemed to appreciate the way in which it could be solved. We record the attempt of a young man, 22 years of age, who had reached the fifth grade of the mission school, to find the number of pence in a pound. He knew the number of shillings in a pound and the pence in a shilling, informa- tion not often obtained in our interrogations. He worked in the following way— 2 «12 42 31 352 74 We noticed among the young married women this same inability to think in nuinbers. A store is kept at the station, and it is customary for the families to make purchases there. These aboriginal women would purchase constantly at the store, but they never had any idea of the price of the articles they purchased. They brought whatever money they had, asked for what they wanted, and tendered all their: money. They took whatever change might be given them. The store was looked after by the schoolmaster. He confirmed our own observations, and remarked that none of them had any idea of money. It is perhaps a slight testimony to the usefulness of our interrogations that they brought out differences in the intelligence of individual aborigines. Investi- gators have remarked that previous attempts to value intelligence in different races have shown differences between races, but these differences have been less great than the differences between the individuals of the same race. One adult full-blooded aborigine whom we questioned seemed much more intelligent than the others. So much was this the case that we took special care to verify that he was a full-blood. And, indeed, it seemed that there was no reasonable doubt that he was a full-blooded native. This man is a farm worker. Ile told us a good deal about superphosphate and the role, it played in farm work. He told us most of their wheat went to England, and England was a very small place with many people; therefore there would be difficulty in growing sufficient wheat there. Pointing to the map he showed us where England was, remarking on its distance from the torrid zone, indicated the position of the equator, and told us that the further you proceeded from the equator the colder it became. He can read, compose a letter, is a good shearer, and has a great deal of knowledge about such things as edible plants, and so forth. All his knowledge he is ready to impart. In sorting the skeins of wool he obtained the best score. His visual acuity was ordinary, being 26 fect by the test we used. These examples are sufficient to show how we tried to get some measure of the aboriginal intelligence. It is, of course, no standardised procedure and will permit no very secure conclusions, Nevertheless, we venture to infer that if our random sample is at all representative aboriginal ability is of a poor kind, and certainly is far below the level necessary for any sort of successful adapta- tion to a white environment. For various reasons, age, illiteracy, and so forth, the number we examined is very small. Of the fourteen examined on the plan already outlined, we con- clude that one has fair ability, and that thirteen range from poor to very poor, The tests we applied are quite fairly within the scope of an average 8-year-old white child. We would again say that we have been searching for some estimate of ability, and by ability we mean the power of perceiving the relations between things apprehended by the mind. We do not forget that successful adaptation to an old or to a new environment depends on other things beside ability—ihe power to resist the white man’s diseases, the white man’s vices, and the desire to succeed. It has been said (Rivers) that native races lose interest when their own culture is displaced, and they despair when faced hy a new environment. We have no means of testing this hypothesis, but the demeanour of these natives does not stiggest a hopeless pessimism. Their keenness on games, their readiness to sing, their friendliness and humour, their anxiety to participate and do well in these tests, rather suggest that their competitive instinct is by no means inactive. We believe that this preliminary investigation is sufficient to warrant a more extensive investigation of aboriginal performance and ability by methods which have become frequent and familiar in our own schools. 75 SUMMARY. . The results of certain physiological tests on the Australian aborigines are presented. . Tests of various kinds of sensory acuity are presented. There is some evidence for believing that their visual acuity is of a high order. Some attempt has been made to assess their intelligence. There is the usual individual variation, but the average level is low. BIBLIOGRAPHY. Burt, C.: “Mental and Scholastic Tests.” London County Council, 1921. 2.

Experiments which were carried out with this object fall into four groups :— I. Estimation of the lengths of simple straight lines. IL. Reaction to the Miuller-Lyer Illusion. III. Estimation of horizontal and vertical lines. IV. Interpretation of pictures showing an illusion based on strong lines of perspective. 1. EstTIMATION oF THE LENGTHS OF SIMPLE LINES. This was carried out by two independent sets of trials :-— 1. A slide was prepared on the principle of the slide used by Professor Rivers in the Cambridge Anthropological Expedition to Torres Straits, Reports Vol. IL, p. 117. The apparatus was made of strong white cardboard, A line, 75 mm. long and not quite 1 mm. wide, was drawn on the face of the slide, finishing 1 em. from its proximal edge. This slide over-rode a similar line 170 mm, long, drawn so that it underlay exactly the first-mentioned line. Movement of the slide cut off any desired length of this second line. The test subject was instructed to move the slide until the two lines were of equal length. This estimated length was then read off on a scale on the back of the slide. The natives were very uncertain of the meaning of equal. A man would set the slide. A query then as to which line was big one, would lead to an instant indication of one or the other line. He would then make the alteration in the direction required by his answer. ‘The performance might be gone through several times before final satisfaction was obtained. Only three men, Numbers 49, 53, and 56, went about the test con- fidently and straightforwardly. Comparative results starting from a closed or an open position of the slide respectively were, therefore, impossible. The results of the tests are given as the average estimates, with the mean variations. 2. The second series of tests consisted in obtaining judgments of the com- parative lengths of lines prepared according to the standard Binet-Simon tests for the fourth- and thirteenth-year groups, The results are given in tabular form. If judged correctly, a dot marking is shown, if incorrectly, a mark 1+ or 2+ is made to indicate that the first or second line was stated erroneously to be the longer. 77 Estimation of Lengths of Simple Lines.

The results prove that most of the subjects are capable of making a fairly accurate estimate of the length of a line. Further, they supply a control experi- ment to the use of the slide for the Miller-Lyer illusion. A low mean variation in the slide test was expected to give a relative test of intelligence. It was, however, observed that some of the lowest mean variations appeared to be due to repetitions of a former judgment not dependent on free estimation, but rather on some locally recognised point on the apparatus. 2. Reaction to MULLER-LyeEr ILLuston. A slide apparatus was prepared in white cardboard similar in construction to that of Rivers, Ibid. Reports, Vol. IT. p. 117, but with the revisions figured in Brit. Journ. Psych., Vol. I., p. 356. A control test was prepared by drawing three sets of the illusion on cardboard strips. The diagram of each was identical with the slide apparatus scheme, but the length of. line, included between the 78 obtuse angles of the oblique lines, was made 75 mm., 65 mm., and 60 mm., respec- tively, the line between the acute angles of the oblique lines being constant at 735mm. Results are given in the following table. When the line between obtuse angles is stated to be greater, equal to, or less than the constant line, the signs +, =, or — are shown, respectively, in the table. An approximate reading for the illusion based on this control experiment is placed in the last column. The subjects who failed in the previous experiment with the simple line apparatus were not tested with the slide apparatus for this illusion, but sometimes gave readings with the prepared sets. Care was taken in carrying out the tests with the slide and with the set diagrams that the figure was viewed frontally and not at an angle. Further, the three set diagrams were submitted in regular order—firstly the one with the longest variable line, then the mean, and finally the figure with the shortest variable line. The middle member of the’series was always presented in reversed relation to the other two, in order to avoid a habit of pointing to the right or left half of the figure.

The older men were much more difficult to test than the younger men, and they quickly tired and lost interest. No. 5 was 55 years of age. The results of Nos. 19 and 39 with the diagrams are quite inexplicable. They reacted well with the slide, and in each case the test with the diagram was repeated after the slide test and gave exactly the same judgments. Rivers (Brit. Journ. of Psych., Vol. L, p. 357) gives the following average reactions to this illusion:-Todas, 59-8; Murray Islanders, 61:1; Uralis and Sholagas, 55°3; English, 57-9, The results of the present series of tests, therefore, approximate most closely to those obtained by Rivers with the English, The remarks concerning mean variation and intelligence, previously stated, apply also in this case. No final judgment of equality could be obtained in the tests with Nos. 36 and 45. Their statements of big one and little one were, how- ever, narrowed down to a difference of less than a millimetre of movement of the slide, and this reading was accepted as an estimate of equality. 3, REACTION TO THE ILLUSION oF ConTicuous IloRIZONTAL AND VERTICAL LINES. This is another test in visual spatial perception which Rivers used in his investigation of the natives of Torres Straits. The method of Rivers (Reports, Vol. IL, p. 108) was to draw a horizontal line 100 mm. in length and ask the native to draw, firstly a vertical line of equal length from the centre of the former line, secondly a similar vertical line from the extremity of the horizontal line, and thirdly a vertical line through the centre of the horizontal line, forming a cross with it. The average results obtained by Rivers for Murray Island men, for the three sets of lines, were 65:7 mm., 77-0 mm., and 90-1 mm., respectively, Children, white and black, exhibited a less degree of illusion; British students still less so, viz., 89°0, 92°5, and 94-5. Todas (Brit. Journ. Psych., Vol. L., p. 339) gave reactions of 75:7, 87°6, and 95-4, respectively. The method employed to test the Australian native was a further development of the slide method. A line 100 mm. long was drawn, and a long line drawn at right angles to this, making a “T” with a long tail, A blank slide was arranged to cover any desired length of this tail. The native made two series of estimations with this apparatus. Firstly, the slide was held so that the “T” faced him with the tail vertical to his front. Secondly, the “T” was placed with the tail parallel to his front and the cross piece to his right. The native was instructed to move the slide until the tail appeared equal to the cross piece. A series of readings was taken in each position, the result being read off by means of a scale on the back of the slide. The following is a table of the findings :— T VERTICAL. T HORIZONTAL.

This is probably a fatigue effect. 4. RECOGNITION OF PERSPECTIVE IN PIcrures, Mr. L. Howie, Director of the School of Design, kindly supplied the sketches for this test. As a preliminary to the perspective pictures, four animal sketches were sub- mitted for identification, ‘The first was a copy of a native rock drawing in the possession of the school. It had the general shape and proportions of a kangaroo, but the open mouth showed a long row of teeth, and the hind feet were bent back and ended in four radiating toes. The sccond was a native drawing of an emu, distorted and conventional in design but recognisable. The third was an excellent sketch of a native companion, a bird of the crane family, but foreign to Central Australia. The fourth a realistic sketch of a dingo. The object of this pre- liminary test was to gauge the ability of the natives to identify a picture as a representation of a known object. I remember many years ago a lecture by a prominent artist in defence of the post-impressionist school of the time, in which he argued that a South African Bushman could interpret a crude native drawing as a representation of an animal, but failed to recognise that animal when por- trayed in a photograph. The argument ran that the unbiassed visual perception of the Bushman recognised a realism in the crude native drawing which Europcan education had destroyed in its protegees, until rediscovered by the post- impressionists, Twenty-eight aborigines were tested with the above four pictures. The dingo was recognised by all. Picture No. I, in twenty-four cases, drew a simple comment of “Don’t know,” or “Can’t know him.” No. 23 stated, “Make him along Adclaide, can’t know him.’ No. 2 guessed, ““Think emu.” Nos. 7 and 19 guessed “alligator.” This picture, in almost every case, caused an outburst of merriment. Picture No. I. was called an emu seventeen times, a turkey once; other cases, “Don’t know.” No. IIT. was called an emu twelve times, a turkey once, an ostrich once, seven men stated they did not know, and seven men who had travelled into lake country recognised it. In one of the perspective pictures two kangaroos were drawn “normally” in black silhouette, These were recog- nised as kangaroos without exception. Sixteen of these twenty-eight natives had had no school instruction at all. These men undoubtedly were able to recognise known animals in what an ordinary European would call a good drawing, When an unknown animal was “well drawn,” or a known animal represented in the conventional drawing of a kindred tribe, they guessed, or confessed ignorance of the object represented. 81 The pictures used to test the recognition of perspective were two black and white sketches. The first portrayed two kangaroos in a perspective scheme com- prising a road, a fence, and a telegraph line with poles. The second showed two blackfellows armed with boomerangs in the verandah of a house in sharp per- spective. In both cases the two figures were identical in outline and size, but the setting of the figures was such that the illusion was presented strongly that the back figure was at least twice the size of the front figure. These pictures were presented one at a tithe to the native who was being examined. He was asked to say what he saw. A more or less complete enumera- tion of the items of the picture followed. In only two cases was there any inter- pretation of the picture as a whole. Nos. 7 and 16 called the blackfellow picture “kurdaitja,” @.e., an avenging party. The examinee was then asked if the two figures were one little one, one big one, or all the same size. In each case where there was a judgment of a large and a small figure, a finger was pressed on the figure judged and the remark made, “That big one,” “that little one,” or words with that significance. The results are summarised in the two following tables. The first concerns the natives who have had no schooling, the second those who have had school training. The method of recording results in the table is to place a “+” mark under “Front” or “Back” to indicate that the front or back figure was judged the larger, a “=” mark under “Both =” to record a statement of equality.

But No. 16 discovered the illusion, apparently, as he stated: “Young man,” pointing to the front figure; “old man,” pointing to the back figure. Nos. 19 and 54 may have seen the illusion in the kangaroo picture, as their judgments are qualified by a statement of equality regarding the figures of the second picture. Not more than three, therefore, of the thirty-two judgments recorded indicate an interpretation of the perspective of the drawings. 82 Pictures —Natives with School Experience. Serial No. KANGAROOS.

This table shows very different results, surprisingly so, as in the course of the examination the good and indifferent results seemed hopelessly confused. The school history was obtained later, and provided the key to the situation. No. 102 had had only eighteen months schooling and was still unable to read. No. 39 was said to have had some schooling, but the amount was unknown, His judgment on the blackfellows was, “That big one, that one little one; yes, same size, one little one, one big one.” Apart from these two natives, the results of the twenty-four judgments of the other twelve subjects show only five in which the perspective was not visualized. The interpretation of perspective is not a matter of intelligence but of experience. My daughter, four years of age, ignorant of letters but well acquainted with pictures, stated that the front figure in each of the pictures was the baby one, when asked if the figures were the same size or not. B._DISCRIMINATION OF NUMBERS BY THE AUSTRALIAN ABORIGINE. The natives at the Mission were almost entirely of the Aranda nation. There are native names for numbers in the Aranda language up to four, viz.: Ninta, one; tara, two; taramininta, three (two and one); taramatara, four (two and two). Beyond this there are native words meaning some, a fcw many, and very many, but no higher numerals are given special words. The proposed investigation had the object of discovering whether this vagueness of terminology covered the extent of the natives’ ability to distinguish numbers. A suggestion had been received that Professor Porteus was using cards with spots in an investigation of this nature in North Western Australia, so the same idea was employed in the hope of obtaining comparable results. White cards were prepared,’nine centimetres square, with black spots about four millimetres in diameter, ranging from one to forty in number. The intended nature of the test was to find out how far the natives could arrange the cards in serial order from one to forty, When the test was applied it was found that the number of cards was too great. Cards one to twenty-one ¢ were used in consequence. These cards were spread out before the native being examined. The proposal to arrange the cards in sequence from one to twenty-one was explained in Pidgin English and such few native words that were at command, combined with a demonstration. he cards were then mixed up and the native told to make the attempt. 83 The results were as follows, in the order in which the natives came up for examination. Sometimes the native was given a start by placing cards, 1, or 1 and 2, to help him begin. Any cards so placed are enclosed in brackets in the records :— No, 2.

No. 8. Minuka.—Male, cire. 45 years, no school. No amount of explanation could make this man understand what was required of him. He was shown cards 5 and 10 and asked on which one big mob marks sit down, on which one little mob sit down. Mr. Heinrich, of the Mission staff, who speaks the language fluently, tried to help the man to make a decision between the two cards, The only responses obtained were, “Can’t know him,” “Don’t know.” The state of affairs at this stage was most unsatisfactory. Mr. Heinrich then appeared with two cards, representing realistically a flight of three and a flight of five ducks, respectively. These were used as the basis of the explanation of big mob and little mob. The spot cards were then presented in pairs for a similar decision, Care was taken that the positions in which the cards were presented were altered frequently, but irregularly, so that the judgment should not be merely a habit of pointing to the left or right card. The examination of the natives on these lines gave the following results. In recording the experiments, the numbers of the pairs of cards are given in ordinary figures if judged correctly, but are in italic figures if wrongly judged. If the cards were wrongly stated to be equal the sign = is added; if the smaller figure was mistaken for the larger the sign + is added. Further, if the spots were counted, the letter “c” is added; if the spots were not counted, no letter is added. If the spots were incorrectly counted, the incorrect count follows the letter “c.” No. 11.

As counting spots on the cards is essentially the same as counting coins, some of the natives performed the sixth year Binet-Simon test of counting thirteen pennies. The valuation of the judging of pairs of cards cannot depend primarily on a right answer. A blind guess has an equal chance of success or failure. A failure is, however, of importance, as it indicates an error in judgment or a blind guess, which is equally damning. The importance of this is shown in:—No. 37: no mistakes in pairing up to 31, 32, yet misplaces 9 and 10 in series; No. 53: no mistakes in pairing, yet had to count 22, 25 to be sure of his ground ; and, finally, No. 56: no mistakes in pairing, yet showed indecision over 31, 33, indicating that his successful judgment was more or less of a guess. The experiments do, however, disclose some degree of order of merit in estimating numbers. The index is supplied by the ratio of the difference between the two numbers to the lower number itself, i.¢., a failure in 5, 6 indicates a failure at the ratio 1:5; a failure in 17, 20, a ratio 3:17 or 1:5°7; a failure at 32, 39, a ratio 7:32 or 1:4°6. Of these three examples, 1!5'7 is a better result or rather a less error than 1:4-6, and so on. A summary has been drawn up on this basis of estimating merit. The result expressing the highest error is taken in each test, and the index figure in the table is the value of “x” in the ratio 1:x for this error. Discrimination of Numbers.

The results of the school children are omitted from the list. The experiment raises the very interesting question as to how much educated people rely on counting in their estimate of numbers. The educated mind is steeped in counting from an early age. A mass of visible units is unconsciously broken up into groups to facilitate the judgment, and rapid counting normally accompanies a movement of the eyes over a series. It is significant that the spots of playing cards are limited by a four spot grouping and then transfer to a picture series; also that large numerals are written with a grouping of figures into threes. I am convinced that five units constitute the mit of immediate recognition, and that estimates of numbers beyond this involve rapid counting, grouping, or guessing. The natives in our serics showed that they were not familiar with numbers. At least thirteen could count to twenty, and of these seven could count back- wards from twenty to one. Yet their counting was laborious, and those that counted backwards seerned surprised with their prowess. I think that rapid counting and grouping can be eliminated as a method of estimating numbers on their part. In no case were all the judgments dependent on counting. Some judgments were rapid, while all counted comparisons were slow and the counting audible and visible. My opinion is that all judgments showing an index above six in the list are shrewd or lucky guesses, and that the results of the experiment in comparing pairs of cards show that the natives possess a decided ability to estimate com- parative numbers by guessing. The method of arranging a sequence of numbers would appear from the results in general to pick out in relief those individuals who have a working acquaintance with figures. The idea of a sequence, in the absence of a knowledge of figures, is too abstract to be grasped by the unenlightened. 87 C.—PHYSIOLOGICAL OBSERVATIONS. 1. Visuau Acurry. Two methods were tsed to test visual actlity. 1. Snellen’s Type—A Snellen “illiterate type” E, 18 millimetres square, was the standard adopted. ‘his letter subtends an angle of five minutes at a distance of twelve metres or 39°37 feet. The letter was centrally drawn on a small circle of white cardboard, which was mounted on a large sheet of white cardboard in such a way that it could be freely rotated, without wavering or eccentric move- ment from the back of the cardboard sheet. The basis of the test was to find the maximum distance at which the orientation of the E could be distinguished. The individual examined faced the test board and held a square cardboard with a similar but large E in front of him and turned this to correspond in position with the E on the test board. The position adopted was recognised by the examiner by means of a large arrow drawn on the reverse side of the cardboard square. A few tests were carried out at close range to school the native in the technique. The first tests, which were made with adult natives, were proceeded with by sending the native to a distance and then having him approach until he could recognise the position of the E correctly. This distance was then noted, and the test repeated several times with the E rotated to different positions. This method needed the presence of an assistant to note the distances. No assistance was available on other days, so the course was marked by signs at ten foot intervals. The test subject was started at a medium distance, and given several trials. He was then advanced or retired ten feet, and the trials repeated until a distance was attained at which the subject made two errors of 180 degrees or one error of 90 degrees in at least five tests. 2. A Modification of Guillery’s Spots—Two sheets were prepared each showing the outline of a man in profile—one black on a white ground, the other white on a black ground. Three rectangular windows were made in each figure in the position of the head, chest, and thigh, respectively. Slides were arranged behind these windows, so that in any of the three a spot 3-6 mm. square could be cxhibited—a black spot in the white background, and vice-versa, The test subject was sent to a distance and approached until the spot was visible. He had to check his statement by pointing to his own head, neck or chest, and correctly indicating the position of the spot shown on the card. The distance at which the spot was picked up correctly was noted, an incorrect indication eliminated. Several trials were made with each subject with each card. The visual acuity tests were carried out towards the end of the stay at Hermannsberg, and adult subjects were not available to any extent, so most of the work was done with school children and young girls. A very noticeable feature of the examination was the great influence of concentration. Most of the boys were keen. The most interested ones peered between the brim of their hats and the edge of the square card held just under the eyes. Most of the girls were shy and lackadaisical and gave poor results. One girl peered intently like the boys and gave a better result than most of them, being outdistanced by only one lad. The Guillery spots gave much lower readings than the E test. These spots subtend an angle of one minute at twelve metres, and this angle is supposed to be the same as that for the differentiation of the E, The boy who gave a remark- able reading with the E test was frankly indifferent with the spot test and gave a mediocre reading. Further work is required to confirm results obtained, as they give evidence of an acuity up to 370/40. On the other hand, whites of the party, and of the district, gave an average reading with the E test of 130/40, which reduces the comparative acuity of the best native reading to about 300% 88 above normal. Great care had to be taken that comrades did not signal to the test subjects. This was frequently attempted at first, but was checked by careful watching. The recorded results excluded any where signalling took place. At times during the examination the sun shone on the boards. Shading the board reduced the visibility, and was discontinued.

OBSERVATIONS WITH Masson’s Discs. Discs were prepared, which were marked with Indian ink on a white back- ground, to give grey bands on rotation representing a blackness of 1/200, 1/250, 1/300, and 1/350, respectively. Trials with these were unsatisfactory, as it was difficult to obtain a definite answer from the natives, especially a negative. An impression was gained that they did see 1/300, and some perhaps 1/350, but the replies were unconvincing. 4. CoLour SENSE. 1. Colour Nomenclature-—This was investigated by asking the natives to name the colours of standard coloured papers and Holmegren’s wools. Mr. B. Maegraith carried out the major portion of this work. The following vocabulary was obtained. The word “indora” means “the very thing’; a reduplication of a word has the significance of a qualification or weakening. White—Tyjilkara indora. Black——-Urpula indora. Red—Tataka, Vermillion—Tataka indora, Magenta—Tataka tataka. Pink—Tataka tjilkara tjilkara. V, deep red, deep brown—Urpula urpula. Cadmium orange—Tataka, Mikado orange—Nduana nduana. Yellow, ochre, pale yellow—Nduana, Dirty yellow, capucine yellow — Nduana nduana. Green, sage green-~Turka turka. Blue green, duck egg, pale green, pale blue—Ilbungera. Light wisteria—Ilbungera indora. Blue, indigo, violet, deep blue— (variously) urakuata ngera. Uipula, “no name,” “blue” Purple—‘“No name.” Puce—Ultmara ultmara. ndtana indora. One boy gave ultmara ultmara. “Ultmara ultmara” is uncertain obviously, it also means “a dust cloud.” It is doubtful if there is a word for bluc; “urakuata ngera” means “like fire smoke” ; It appeared on the second day of questioning a group of girls who had replied “no name” or urpula. The word was unknown to the Mission staff, who have a good command of the language. 2. Colour Blindness—-Many natives, of both sexes, were tested with Ishihara’s colour plates, but no cases of colour blindness were detected. 3. Colour Contrast—A hole was cut in the centre of a sheet of bright blue paper. This was laid on a grey background and covered with tissue paper. The yellow tinge of the grey circle appeared clearly to us, but not one of the natives noticed it. When interrogated, they did not look closely, they would glance and reply “blue,” the colour of the ground, or “don’t know.” 4. Colour Preference-—This test was carried out with females. Strings of bright “butter beads” were laid out on a form. The individuals were brought up singly and asked which they liked best. A small handful of these beads was given them. Beads selected were then removed from the display, and they were asked again which they liked best; fewer of the beads of this choice were given, and soon. The beads were white, black, royal blue, turquoise blue, green, yellow, and red, The results were plotted as a graph for each colour, the number of times the colour in question represented the first, second, third, fourth, fifth, sixth, or seventh choice, The centre of gravity of the graph was made the indicator of rela- tive preference, The following order of preference was obtained :— Juveniles (17).—Green, yellow, black, royal blue, red, turquoise blue, white. Adults (7).—Red, turquoise blue, black, yellow, royal blue, white, green. Considerable difficulty was encountered in examining the elderly women. In two cases the results were deleted because they simply picked the nearest colour D 90 each time. As there were 17 juveniles and only 7 adults, the order of preference for the total 24 cases was the same as that for the juveniles. The high order of black was a surprise. It is, of course, in good taste. 5. Hearinc. No test of auditory acuity was carried out. Professor Kerr Grant kindly supplied a Galton’s whistle for the use of the expedition. The whistle was blown by means of the pressure pad of a sphygmomanometer. The whistle was not graduated in wave lengths. There was difficulty in making the natives differen- tiate between the hiss and the clear whistle note. The test for the upper auditory limit was carried out repeatedly in the presence of natives and members of the expedition. The upper range appeared to be identical in both blacks and whites. 6. TAaActTitE SENSATION, A number of Von Frey’s hairs were prepared by mounting one end of a strand of horsehair or silkworm gut with glue between two narrow strips of cardboard. Professor Kerr Grant kindly measured the diameter of the hairs for me, The pressure weight of each hair was measured by pressing the hair vertically on the pan of pharmaceutical scales. This last measurement is somewhat of a conjuring feat, but repeated estimates were made to ensure as great a degree of accuracy as possible. ‘The hairs were graduated by dividing the pressure weight by the area of cross section in square millimetres. The values for the hairs worked out as follows :— Pressure Nature of Pressure Diameter Diameter Area in Divided by Hair.. Wt. in gm. in Inches. in mm. sq. mm. Area, I. Horsehair .... 0-455 0-009 0+2285 0-041 11-1 Il. ‘a an 0-650 0-009 0-2285 0-041 15:8 Il. an wile, 1-040 0-009 0-2285 0-041 25°3 - a 1-625 0-011 0-2793 0-061 26:7 93 wid 1-495 0-010 02539 0-050 29-9 IV.

The natives were told to shut their eyes, and were watched to see that they did so, and as an additional precaution the part stimulated was screened. They were told to say “Yes” each time they felt a touch. From time to time no touch was made at the normal stimulation interval. ‘lhe softest hair giving a response was recorded. This was the most satisfactory test carried out with the natives in regard to definiteness of response. The following is the tabulated list of results obtained :-— Tactile Sensibility.

These results are surprising, as the skin of the natives appears harsh and parchment-like and would be expected to be relatively insensitive. The only relative figures I have to hand are some figures of Von Frey, quoted by Head Studies in Neurology, Vol. I., p. 321:—Finger, 3 gm./sq. mm.; back of hand, 12 gm./sq. mm.; forearm, 8 gm./sq. mm., or less. These results must concern non-manual workers, as I have tried my hairs on labourers and find that hair II. is an average finding for the tip of the index finger. The mean results for forearm and leg in my series might be lower if a more sensitive hair had been available for the tests, as the “I” results represent a substantial majority in these two sites of stimulation. 7, Patn SENSATION. The Australian aborigine is so hardy in withstanding physical injury, that some estimation of pain sensitivity is interesting. An algesimeter was prepared from a spring balance graduated in half ounces up to five pounds. This was tested against standard weights and found accurate. A drawing pin was pushed through a piece of cardboard to steady it, and placed point up on the pan of the scales. The scales were adjusted to zero. The test subject was instructed to place the tip of the right index finger on the point of the pin, and then press down until hurt too much. The following table gives the best effort of each individual in ounces of pressure -—_ WHITES. or NATIVES. Adult Men. Boys. Girls.

A rueful examination of the finger was the general rule, as though the experience was more painful than was liked. 8. Reaction TIME. An attempt was made to estimate reaction times to light and sound. The native has a reputation for lagging in following the later of two consecutive orders, i.é., carrying on with the original order when new orders are given. A third test, therefore, was made after the simple reaction to light and sound; the native had to respond to a sound stimulus, but not to light. Several light stimuli were made 92 before the sound signal was given. Professor Hicks kindly loaned apparatus for the experiments. The apparatus consisted of a clockwork drum with smoked paper. A small electric globe and a switch in one unit, and an electric buzzer and switch in another unit, were connected in parallel. These units together were connected in series with a couple of dry cells, a spring switch, and a marker recording on the drum. The subject examined pressed down the spring switch. When the light or buzzer switch was closed the circuit was then complete and the marker point on the drum depressed. In response to the signal, the native released the spring switch, the circuit was opened, and the marker point rose again. When the drum was in motion, the interval between stimulus and response was shown by the interval between the downward and upward movement of the marker line. The time relation was read by timing a complete revolution of the drum, 42 seconds, and dividing this by the circumference of the drum, 500 mm. Each millimetre on the drum record, therefore, indicated a time interval of 0-084 seconds. Unfor- tunately the drum revolutions were not constant, and these figures are subject to a 10% error. The natives were schooled and practised in the reactions before the actual experimental record was made. The following results were obtained. Figures represent time in seconds :-— Koringili—Male, 20 years of age. No school:—l. Light Stimulus: 0-336, 0°412, 0-403, 0-386, 0°294, 0°302, 0-318. 2. Sound Stimulus: 0-285, 0°285, 0-285, 0-285. 3. Ignore Light, Respond Sound: 0-420, Differ- ence, 2 and 3: 0-135. Manasseh.—Male, 20 years of age. Six years school:—1. Light Stimulus: 0:268, 0°168, 0-236, 0202, 0-236, 0-168, 0-236. 2. Sound Stimulus: 0°218, 0-176, 0-151, 0-160, 0-160, 0-168, 0-160. 3. Ignore Light, React Sound: 0°320. Difference, 2 and 3: 0-169 to 0-102. Engerilyeka.—Male, 40 years of age. No school:—l. Light Stimulus: 0°252, 0°227, 0:202, 0-168. 2. Sound Stimulus: 0-244, 0+236. 3. Ignore Light, React Sound: 0-470. Difference, 2 and 3: 0-234 to 0:226. Paddy.—Male, 50 years of age. No school:—1l. Light Stimulus: 0-386, 0-260, 0-260, 0-236. 2. Sound Stimulus: 0-320, 0-160, 0:151, 0-151. 3. Ignore Light React Sound: 0-495. Difference, 2 and 3: 0-344 to 0-175. An attempt was made with a boy but his results are an interesting commentary on divided attention. The environment had too many distractions. Eugen.—Male, 13 years. Four years school:—1. Light Stimulus: 0-925, 0-540, 0-540, 0°398, 0°368, 0-510, 0-316, 0-286, 1-01, 2:02, 0-453, 0-453, 0-687, Schafer (Schafer’s Text Book of Physiology, Vol. LL, p. 610) quotes the following average reaction times from Richet:—Sudden Sound, 0-150 sce; Elec- tric Flash, 07195 sec. James (Text Book of Psychology, 1904, p. 124) quotes reaction times for Sound, 0°136-0°167; for Light, 0-150-0-224 sec. For com- plicated reactions, white signal or no signal, the time was lengthened by 0-03- 0-05 sec. In our experiments the reaction times were usually longer than those given by these authorities, and were very variable. The lag of the complicated reaction measured against the shortest reaction time is four to seven times as long as the figures quoted by James. ‘he variability of the responses, however, may account for a large part of the apparently excessive time for a complicated reaction. 93 D.—OBSERVATIONS ON INTELLIGENCE. The problem of estimating the intelligence of the Australian aborigine in terms of the intelligence standards accepted by European peoples bristles with difficulties. The natives have so few social characteristics in common with our civilization. The semi-civilized native, represented by the majority of the natives at the Mission, has some points of contact with our systems of thought, but a frank application of standard intelligence tests cannot give results which can be com- pared fairly with those obtained from Europeans, These natives still live a camp life; they frequently discard their clothes and live a bush life; they are ignorant of money, which only enters occasionally into their systems of barter with the Europeans. Many have attended the Mission school, but the teaching is hampered by the camp life, the nomadic disappearances, and by the absence of books, toys, problem games, papers, shops, and civilized conversation at home, which play a large part in the education of the European child. On the other hand, the teaching is hampered by the numerous duties which the Mission teacher has to combine with that of schoolmaster. Observations on intelligence are, therefore, beset with incalculable factors, but this does not seem an efficient excuse to do nothing. The present paper is presented with this apologia. All adult natives examined were full bloods. 1. Brnet-Simon TEst. Time and circumstance allowed of only one complete examination. No. 101 (General Series), No. 13 (School Series) —~Percy, male, aged 11 years; 34 years at school. This boy ran naked in the bush until he was seven years of age. Since that time he has lived at the Mission, He is a full-blood aborigine. Burt’s arrangement of the Binet-Simon scale was used. Mr. Heinrich acted as interpreter, as Percy was more familiar with the Aranda language than English, He accomplished tests to number 25—middle of sixth year—satisfactorily. In the colour test, “blue” was called “Urbula” (black), but this is normal with these natives. No. 25 concerns coins —This was a failure. No. 27 concerns definitions ——This he could not comprehend properly. He did, however, state a horse had four legs, and that a table is wood, which are definitions better than use, so he was conceded this test, which demands use only. No, 28. Repeating five figures.—Failed. No. 33. Concerns coins.—Failed. No. 36 was the last of the series of successes. No. 42. Months of year—Succeeded. No. 47. Sentence building —Succeeded. No. 48. Copying two diagrams.—One and three-quarters right. Succeeded, No. 53. Sentence building —Succeeded. Percy’s score, therefore, reads: 36—3-++4=37=7 years, 4 months. Percy could only repeat four syllables in English, but accomplished twenty- one in Aranda. When testing for discrimination of numbers and visual spatial perception, three of the Binet-Simon tests were included :— Firstly. No, 38. Eighth year——Counting backwards from twenty (vide Dis- crimination of Numbers) : Nine adult males who had had schooling —Seven succeeded, two failed. Four adult males, without schooling, who could count to twenty, all failed. One adult female, with schooling, succeeded. Two schoolboys failed. 94 Secondly. No. 56. Twelfth year—Inferring situation or emotion in a picture (vide Visual Spatial Perception) : Two out of thirty succeeded. Thirdly. No. 57. Thirteenth year.—Resisting suggestion of lines (vide Visual Spatial Perception) : Twenty-nine adult males tested—Correct, thirteen: School, six; no school, six; doubtful, one. Left line longer (counted a success by Yerks), nine: School, three; no school, six. Failed, three: School, one; no school, two. Unable to comprehend test, two. Three schoolboys tested—Correct, two: Fifteen and thirteen years of age. Failed, one, eleven years of age. Four adult females tested.—Correct, one, schooling. Failed, two, no school- ing. Unable to comprehend test, one. 2. PERFORMANCE TESTs. 1. Puzzle A consisted of nine simple geometrical figures cut out of a sheet of thick cardboard (vide fig. 1). A roughly executed landscape in thick brush _—— WH Wy Pe oO Fig. 1. Actual size, 18 in. by 12 in. lines gave orientation lines for the circle, square, oblong, and equilateral triangle. Other figures would fit in one direction only, and the lines were of less importance. Only one man, No. 49, of thirty-eight individuals tested, troubled to match lines in placing the pieces. The test was shown to the examinec with all the pieces in place, The pieces were then pushed out of their holes before him, the board laid down in front of him, the pieces placed right side up, and the test subject told to make each one sit down in its proper camp. Individuals who did not complete the test resigned after vainly trying to force wrong pieces into the wrong holes by strong pressure. Similarly, the ones that took a long time to complete the test usually wasted time by trying to force misfits to conform to the hole selected. 95 The average civilized child of four years of age should complete this test. This was the first occasion in which any of the natives had met with a problem of this nature. The following is a table of results -— Pugzle A, Serial Years Number of Pieces Time Number. Sex. Age.

Pusezle B—This was a Dearborn Form Board, kindly lent by the Director of Education through the good offices of Dr. Constance Davey. It was made of half-inch wood, with the pieces fitting into quarter-inch depressions. The board and pieces were stained uniformly black. The scheme of the puzzle is drawn diagrammatically in fig. 2. It will be seen that there are two sets of four geometrical figures. For one set the corresponding pieces are two halves repre- senting a longitudinal division of the figure. For the second set there are three pieces, representing a transverse division with a longitudinal subdivision of one half. The big difficulty in the puzzle arises if the subdivisions last mentioned are 96 arranged longitudinally; they fit satisfactorily, yet the puzzle is insoluble until this arrangement is broken up. If the subject has the good fortune to place the non- subdivided half in the form first, the solution is much easier. With four chances of making this primary mistake practically all experienced it, yet with the diamond and hexagon it seemed more difficult to resolve than with the other figures. This puzzle, unlike puzzle A, had as a complication the possibility of pieces being wrong side up. LH Fig, 2. Actual size, 18 in. by 12 in. The board completed was shown to the native. The pieces were tipped out in front of him, and he was told to put them back into their proper camps. The following is a lst of results :-— Pugsle B, Serial Years Relative Success Number. Sex, Age.

Estimation of Length of a Line with a slide apparatus (vide Visual Spatial Perception). Twenty-nine male adult natives were tested with this apparatus -— Six failed completely—Nos. 1, 3, 7, 8, 9, and 16. ‘Two gave very big mean variations—Nos. 5 and 10. The remaining twenty-one performed the test satisfactorily. Three adult females—Nos. 60, 66, and 69-—failed in the test. 4. Spotted Card Tests (vide Discrimination of Numbers).—Twenty-six adult natives were tested by showing pairs of cards with different numbers of spots. They had to state which was the greater card with the number of spots :— Three could not be made to understand what was required of them. Two could only understand in so far as birds were drawn instead of simple spots. Four more were poor at guessing. The remainder, seventeen in number, were remarkably good at guessing. Only those who could count well were able to arrange cards in a sequence. 5. Porteus Maze Tests——-The results here were marred by a mistake in copy- ing the fourteenth year maze. The mistake was overlooked owing to a last minute hurry before departure. This error spoilt the first major slip-away trap of the test, but left the second intact. Also, the maze tests were carried out in part only, as a separate series of tests was found to be unfeasible, and this problem was slipped in at the end of a long series of other examinations. The fifth year maze was used as an explanatory basis for the test. The native was told it was a cattle vard, and, tracing the course with a pencil, it was shown that the bullock must not go down any of the races where the end was closed. He was then given a pencil and told to go ahead with the sixth-year maze. The track was marked in pencil and a separate sheet used for each person. The records were preserved. The following is a table of results. If the maze was correct, 1e., if the line drawn did not in any case go beyond the margins of any outlet in a wrong direc- tion, a sign “R” is recorded . Lf the line transgressed beyond the limits of any outlet in a wrong direction the error is recorded by the sign “E,” followed by a figure stating the number of times an error was made in executing the maze. The Roman numerals denote the various mazes in their year values; the garbled four- teenth year maze is denoted by the sign G 14:— PORTEUS MAZE. Years Maze Results. Age. School. VI. VI. VIII. IX.

This is an elaborate form of noughts and crosses, Three ‘concentric” rectangles are drawn on the ground. The rectangles are joined together by diagonal lines at the corners, and by perpendicular lines at the centres of the sides. Sticks or stones are used as markers, the intersections of the lines and the three rectangles are the points of attack. The object is to place three markers on three consecutive points in a line. Children were observed play- ing this game and showed themselves proficient. Girls do not play this game. The girls are good at cat’s cradles. A large number of these were collected by Mr. Hale and Mr. Tindale for the Adelaide Museum. Boys do not play cat’s cradles. 2. Memory.— i. Remote memory of the natives is very good. Older members of the tribe can give detailed descriptions of long distant incidents, There is an eight group marriage system in the tribe, and everyone is tribally related to everyone. Even the small children appear to know the precise tribal relationship between all the individuals in the community. ii. Immediate memory was actually tested only in the case of the boy Percy —auditory, twenty-one syllables; visual, one and three-quarters of two diagram tests. Dr. Harold Davies found that the natives were very quick in picking up and reproducing singing notes. ui, Rote memory—Pastor Albrecht expressed the opinion that the Christian natives were fairly good with their catechism as long as the normal order was preserved; if, however, the order of questioning was changed about, they became confused. 3. Conservation —Vhe natives have no idea of conserving food or clothing in ordinary life. Starving natives will eat as much food as they can hold, if it be given them, but will not think to preserve the surplus. If a man be given some 99 good clothes, he will exchange them readily for the ruined garments of a friend. In normal life they have no need to conserve food; while clothing is worn, if at all, in imitation of the white man. They do conserve their native tobacco, which at times has to be collected at a distance. They are extraordinarily careful in the use and preservation of any plug tobacco which they may receive from white people. 4, Mental Defective—One full blood youth was mentally defective. No relatives were afflicted similarly. He was microcephalic. He exhibited idiolalia. He was able to point out eyes, mouth, etc., in the picture of a dingo. He was good tempered, and not vicious in habit except for open masturbation. He accom- panied his relatives in their wanderings. E.—SCHOLASTIC TESTS. Two afternoons were employed in class examination of the school children. All the children are taught in one room by Mr. Heinrich, who combines. the occupation of schoolmaster with multifarious other duties at the Mission. School hours and lessons are scheduled on normal lines, but are subject to contingencies. School books are partly in English, partly in the Aranda language. All books are kept in the schoolroom. Outside school hours the children have duties about the Mission, or with relatives in the camp nearby. They retire to dormitories, one for boys, and one for girls, about 8 p.m. The senior scholars varied from eight to fifteen years of age, and had had two anda half to four and a half years’ schooling. They were examined in writing, spelling, arithmetic, and drawing. Junior pupils were mostly about six to eight years of age; some were older, being new from the bush, All had had about four months schooling, and were unable to write. They were examined in drawing only, but they exhibited their prowess by chanting letters of the alphabet as they were written on the blackboard. During the examination, copying was prevented as far as possible by alternat- ing seniors and juniors, and by supervision. Most of the children were full blood aborigines. Some were the offspring of one full blood parent, and one half white parent. ‘These latter children are “6307 indicated by the mark “3” in the tables of results. Senior Scholars. Nature or TEsts. The material for the tests and their interpretation was drawn from Burt’s Mental and Scholastic Tests (London County Council, 1921). Writing and Spelling—RBlank unruled sheets of paper were issued, and on this each pupil wrote his or her name. The following words were then read out slowly and repeatedly by Mr. Heinrich, and the children wrote down the words—a, it, cat, run, bad, but, table, even, fill, money, sugar, number, rough, raise, scrape, surface, pleasant, saucer, decide, business, carriage. These words were taken from Burt’s Graded Vocabulary Test (p. 354), and represent the first three of each set of ten words that he gives for the age groups 5, 6, 7, 8, 9, 10, and 11. Owing to language being essentially foreign, pat and bat were accepted for bad, race for raise, and suffers for surface. Writing was judged from these answers in accord- ance with Burt’s specimens, p. 371, e¢ seg. Spelling merit was recorded by the number of words corrcctly spelt. This figure was multiplied by 10/3, and awarded an age ratio by reference to Burt’s Norms for Boys (p. 402), plotted as graphs. Where the score was a figure below the lowest norm of six years, an arbitrary age was assigned by reference to an ideal extension of the graph. 100 Arithmetic—This examination was Burt’s test of Four Fundamental Rules, pp. 366 to 369. This represents a series of problems in addition, subtraction, multiplication, and division. The score is read by the number of correct figures given by five minutes’ work on each set of problems. Typewritten copies of Burt’s tests had been prepared. Firstly, each pupil was given the sheet of the sums in addition, face down. Lach child then wrote his or her name on the reversed sheet. The nature of the problem was explained, At a signal, all the children turned over their sheets and set to work. After five minutes, at an order, all the sheets were turned over again and collected. A similar procedure was carried out for the sheets of sums on subtraction, multiplication, and division, respectively. ‘he score for each sheet was read in accordance with Burt’s instructions, pp. 301-302, and an age ratio given to the score by reference to graphs prepared from Burt’s Norms for Boys, pp. 405-406. Graphs were prolonged ideally to junior ages below the lowest given norms of six years for addition, subtraction, and multi- plication, seven years for division. Drawing—1. The children performed the Porteus Maze Test for Age IV. They all succeeded. The efforts varied in excellence of performance and were graded into three classes:—Class I., lines between angles straight, well centred, and parallel to the sides of the figure; Class I1., lines less straight, etc; Class III., lines meandering. This classification, of course, only refers to variations in neuro- muscular control, and care of execution. This grading brought out an interesting sex differentiation :—-Class I.: Boys, 5. Class Il.: Boys, 12; Girls, 7. Class IIL: Boy, 1; Girls, 5. 2. Sheets of plain paper were distributed and the children told to draw pic- tures of a man, an emu, anda dog. The assessment of the merit of these drawings and their co-relation to an age ratio is no easy matter, An attempt has been made to do so, after a careful noting of the points of each picture, and a study of Burt’s comments and examples, pp. 317-326, 383-394. The general features of the children’s drawings can be analysed as follows :— Total number, 32—Boys, 17; girls, 15, Drawings of Men: Man, Type A. 1—Profile facing left, walking. Ilead upright oval, anterior line shows angular prominence of nose, then depression of lips, then angle of chin, and then is carried back and down to join the anterior line of the chest. Posterior line of head curves in to indicate neck and is con- tinued into the posterior body line. Anterior and posterior body lines convex, and continued below into anterior and posterior lines of left leg, which converge to the ankle without indicating the bulge of the calf. The lines then turn to the left to form a roughly triangular foot without indication of toes. The lines of the right leg, similar in character to those of the left leg, join the posterior line of the left leg, sometimes slightly overlapping this line. Drawn by: Toys, nil; girls, 3. Man, Type A, 2—Similar to A. 1, except that posterior body line is curved ta show hollow of back and prominence of buttock. Drawn by: Boys, 3; girls, nil. Man, Type A, 3—Similar to A. 2, except that posterior line shows strong angle to represent prominence of the left shoulder. Drawn by: Boys, 6; girl, 1. Man, Type A. 4—Similar to A. 1, but anterior line of head shows no features. Drawn by: Boy, 1; girls, nil. Man, Type A. 5—Similar to A. 3, only left leg is posterior and right leg lines join anterior line of left leg. Drawn by: Boy, 1; girls, nil. ‘otal numbers: Boys, 11; girls, 4. 101 Man, Type B.—Head and body as in Type A., but body continued below into two legs. Anterior body line runs on down front of one leg, round foot up to the crutch, then down front of the second leg and returns to con- tinue in the posterior line of the body. Drawn by: Boys, 2; girl, 1. One of these boys shows the body line typical of A. 3. Man, Type C.—Head circular. Body and limbs linear, Legs bent to indi- cate: running left, girls, 2; running right, girl, 1; legs scribbled, girls, 2. Total girls, 5. Man, Type D, 1—Tlead oval, body oval, triangular skirt, legs with feet turned to the Icit. Drawn by: Boy, 1. Man, Type D, 2—Head oval, with loops added to left side to represent nose and lips. Legs with feet turned to left. Drawn by: Girl, 1. Man, Type D, 3—Head circular, body triangular, legs with feet turned out, Drawn by: Boy, 1. In addition, one boy and one girl drew the head and bust only of the man, the fragment being of the A. type. One boy and three girls did not attempt the drawing of a man. Eyes, Types A, and B.—Represented by dot under an arc: Boys, 4; girls, 1. By dot only: Boys, 7; girls,0. Unrepresented: Boys, 2; girls, 4. Eyes, Type D.—Unrepresented: Boys, 2; girl, 1. Eyes, Type C._—No features, twice; two eyes only, twice; two eyes, vertical line for nose, cross line for mouth, once. Ears—These were drawn by five boys and one girl. Hair of Head.—This was shaded in by six boys and one girl. Three boys drew a moustache, one boy a beard and side whiskers. Arms —In pictures of Types A. and B. these were always shown stretched out to the left. ‘The arms took origin from the back line of the body in nine pictures by boys and two by girls; from the middle of the shoulder area of the body in four pictures by boys, and were omitted by one girl. The body was represented as transparent to the right arm by two boys and two girls, The arms originated in the anterior chest line in D. 1 and D. 2, and from the neck in D, 3, and from the head or body line in type C. The arms were somewhat shaped by ten boys and no girls, The elbow was indicated by eight boys and one girl. Three boys drew the hands with five fingers, three with four fingers, and four as enlarged ends of the arms. Only one girl of the A. and B. groups indicated a hand, and that with three fingers. Two C. type pictures gave cross lines, and one circles, to represent hands. Knees.—Six boys and one girl gave some indication of knees. The girl, type A. 3, produced a very confused picture by extending the lines of the right leg up to the level of the hips. Hals—These were occasionally represented, The simplest form was a trans- ' verse line across the top of the head. Three boys and five girls did this. Two boys added to this shading to indicate the crown of the hat. ‘Three boys and two girls drew a crown to the hat outside the line of the head. Clothes —The great majority of the pictures gave no markings on the body or limbs to suggest clothing, except that six boys and one girl shaped the heel of the foot squarely, suggesting the heel of a boot, and one other girl added spurs to this heel. Yet there was no representation of natural features of a naked body or scarring, except that one girl added a rectangular pendent in the crutch of a type B. picture. Four boys did make an effort to represent clothes. No. 14 drew a double line across the neck, and a similar line across the hips, and added two vertical lines down the chest and a curved line across the shoulder. No. 9 drew a single line across the neck. No. 10 did this and added some vertical lines. 102 No. 15 drew a line across the neck, and shaded the chest vertically and the hips horizontally. D. 1 is probably a representation of a skirt. Weapons—One boy and one girl drew double lines from the hands to the ground for a stick or a gun. One boy drew a crude gun extending horizontally from the arms. One boy showed a shield in the left hand, and a boomerang in the upraised right hand. One girl drew a crude shield for a type C. man. Action—This is well represented by four boys and one girl, fairly by five boys and three girls. Proportions are given in the tables of results. The length of the head from vertex to chin is taken as unity, and length of body, legs, and arms expressed in terms of this unit under the symbols B/H, L/H, and A/H, respectively. Drawings of an Emu: ‘These were carried out in a much more spirited manner on the whole. The bird was invariably represented facing left, and in profile. The action of running was realized excellently by two boys (Nos. 1 and 3); well by six boys and one girl (No. 23), fairly by one boy; slightly by two boys and one girl. Action was nil in drawings by six boys and thirteen girls. General outline was excellent in the picture by one boy (No. 3). His was the only case where the curve of the crest met the beak at a sharp angle. His was also the only case where a three dimensional character was given by contour lines of feathering. Otherwise, outline drawings were as follows :-—Good, six boys, one girl; fair, seven boys, three girls; poor, one boy, three girls; crude, two boys, eight girls. Shading lines were common in this picture only, eleven boys and three girls attempting some representation of feathering, The thighs were shaped by eleven boys and two girls. The hock joint was represented by fourteen boys and two girls. The legs were drawn as simple straight lines by no boys, but by nine girls. The feet were represented in a natural fashion by three boys; in a semi-natural fashion by three boys; in a conventional manner as a trident by nine boys and eleven girls; feet were omitted by one boy and four girls. Drawings of a Dog: This animal was pictured invariably in profile facing left. Action was portrayed excellently by five boys (Nos. 1, 3, 11, 14, and 15); well by one girl (No, 28); fairly by six boys and four girls; poorly by three boys and one girl; action nil, three boys and six girls. Three girls did not attempt the drawing. The general outline was excellent in the pictures by the five boys and one girl men- tioned above; good, one boy; fair, six boys, four girls; crude, five boys and seven girls. The drawing by boy No. 11 was remarkable, being futurist in character but realizing intense action. The ears were drawn as follows:— Two ears erect, three boys, eight girls; one ear erect, two boys, one girl; one ear erect, one drooping, one girl; one ear drooping, eleven boys; two ears drooping, one boy; no ears, two girls. Tails were almost always long and curving up or coiled up. One boy drew a stumpy tail. ‘Three girls drew long down- . turned tails. Composition —-Five boys and nine girls made no attempt to combine the figures. Eight boys and two girls made some attempt to portray a chase. A more realistic result was obtained by four boys (Nos. 3, 11, 14, 15). As the full blood aboriginal children and the three-quarter caste children live under identical circumstances and receive the same education, it is interesting to note if the results show any variation where there has been an infusion of white blood. The figures in the preceding table have, therefore, been split up into age groups, and further divided according to sex and blood, and average figures calculated. Nos. 16 and 23 have been eliminated in these averages as their period of school has been relatively small. Remarks on Pictures Draw- Scholastic Mental Ages. Type of Proportions ing Pic- P.IV. tures.

It is tempting to draw a conclusion that the full-blooded children are retarded in mental growth with increasing age to a greater degree than children with some degree of European ancestry. The numbers are too few to warrant this deduction, however. Junior Scholars. Porteus Maze III]. and IV. year tests were judged with regard to quality of performance. Classes IV. and V. were added to the three classes already used in the case of the senior scholars. Class IV. represented efforts where the test line touched, or nearly touched the maze lines. Class V. to cases who failed in the test by overstepping the prescribed boundaries. The following is a summary of results :-— Mental Age Number Examined. Porteus III.

Black.) [Read June 12, 1930.] Piates V. To VIT, At the end of October and the beginning of November, 1929, the writer had the opportunity of accompanying Mr. E. Julius, the Conservator of Forests, and Mr. C. I. Goode, Pastoral Inspector, in making a rapid survey for commercial Sandalwood of the district north-west of Port Augusta. From Port Augusta the general direction of the East-West railway line was followed to Tarcoola, pass- ing through Bookaloo, south of Pernatty Lagoon, round Lake Windabout, passed Bellamy’s Well, north of Lake Hanson, and through Coondambo, Kingoonya, and Wilgena. We then proceeded west of north for about 80 miles, passing through Wilgena country out into the unoccupied lands. Turning now north-eastwards, our route reached to about 100 miles north of Tarcoola, We then turned in a south-easterly direction, passing through McDouall Peak Station, The Twins, Mount Eba, Mount Vivian, Parakeelya, and Chance’s Swamp (Roxby Downs) to Andamooka Station, west of Lake Torrens. We then proceeded southwards through Arcoona and Yeltacowie to Bookaloo, and thence back to Port Augusta (see map). The distance thus covered by motor car was, approximately, 736 miles. I would like here to express our gratitude for many kindnesses received from Mr. and Mrs. Pick, of Coondambo; Mr. and Mrs. Taylor, of Kingoonya; Mr. and Mrs. MacBride, of Wilgena; Mr. and Mrs. Jacob, of McDouall Peak; Mr. and Mrs. Rankine, of Mount Vivian; Mr. and Mrs. Greenfield, of Roxby Downs: and Mr. and Mrs. Fowlis, of Andamooka. The object of the expedition was, more particularly, to ascertain the distribu- tion and abundance of commercial Sandalwood, Eucarya spicata (Fusanus spicatus), and to try and find specimens of another species, Santalum lanceolatum, During the journey, notes were made of the botanical features of the country passed through, and a collection was made of the species of plants seen. Un- fortunately, the long period of drought had affected the flora very adversely. The plants thus collected were later submitted for identification or confirmation to Mr. J. M. Black. In spite of the weather having been so dry, the number of species noted (and mostly collected) was 149, with five varieties in addition. Only ten af the species were introduced. A new species of Swainsona (S. dictyocurpa Black) was found at Bitter Well, and a new variety of Zygophyllion fruticulosum (var. brevi- lobatum Black) north-west of Tarcoola. Bergia perenmis is a new record for South Australia, and Tephrosia sphaerospora had previously been found only north of Cooper’s Creek, Both species belong, also, to Central Australia. INFORMATION REGARDING COMMERCIAL SANDALWOOD (Eucarya spicata, formerly Fusanus Spicatus). On the route followed, Sandalwood country is entered at about 14 miles beyond Port Augusta. It may then be met with up to about 53 miles north to the neighbourhood of Pernatty Lagoon. All the merchantable stems have been bois Xounghusband ——— L Bagson Clare ES goawler sourn| ° < it AUSTRALIA ere 142 “pulled.” Only occasional small or distorted bushes have been left. There seems to be a very considerable waste of the smaller wood and the branches, which possibly may be worth collecting for the extraction of the oil. Quite a big pro- portion of each shrub that had been pulled was discarded. At 54 miles a special inspection was made of the Sandalwood that had been pulled. Some dead trees were noticed. In this and in other parts inspected the Sandalwood has been hard pressed, and many plants have died. During the rabbit invasion some years ago, when these animals were desperate for food, they climbed up shrubs which gave them any foothold and sprawled out on the hori- zontal limbs, nibbling the accessible bark. In many places Sandalwood and some other bushes have been extensively rabbit-scarred in this way. Then, in addition, there has been the present prolonged drought, so that Sandalwood bushes, already handicapped by rabbit injuries, have now. in addition to resist extreme lack of moisture. This probably accounts for the death of trees, some of which have only recently died. At Kingoonya, a photograph was taken of such a Sandal- wood with the lower branches hare and dead as the result of injury by rabbits. (Plate V., fig. 1.) At 81 miles from Port Augusta, Sandalwood had recently heen gathered. In all these cases only the poorer specimens had been left. Sandalwood was again found east of Lake Hanson, and thence at intervals to East Well Homestead. Some of the shrubs were well developed—one was found 10 feet high. Here (near Lake Hanson) two species of Loranthus were found growing on the Sandalwood. Between Coondambo and Kingoonya, further Sandalwood was seen, and at the latter place, quite near the station, a number of bushes were inspected, some severely injured by rabbits. Here, also, was seen an example of the Bitter Peach (Eucarya Murrayana or Fusanus persicarius). This patch of Sandalwood is quite convenient to the station, and might form an admurable plot for observation. The Sandalwood in general occurs along, or at the foot of, the more sandy ridges in country containing Myall, Mulga, some Bullock-bush, Bluebush, etc. Between Kingoonya and Wilgena no Sandalwood was seen. On passing out from Tarcoola into the Commonage, and passing through this in a north- westerly direction, only a few Sandalwood bushes were observed. In our course northwards of Tarcoola, Sandalwood disappeared or was very scanty. It was not seen on McDouall Peak Station, or thence to Mount Eba, being only encountered again when Parakeelya Station was entered. Here it grew in abundance, though some of the best had been pulled. his area was somewhat distant from a rail- way station. Sandalwood was met with on the read from Mount Vivian to Parakeelya Station at about 18 miles, and then 11 miles of Sandalwood country was passed through. A scale insect was found here, infesting, particularly, Native Peach, but also Sandalwood. This may be a pest of serious import. Passing southwards from Parakeelya Station to Arcoona Caves, and thence eastwards towards Chance’s Lagoon, considerable quantities of Sandalwood had evidently been pulled, and some shrubs still remained. Large heaps of chips showed where the branches had been cleaned. Considerable quantities of oil must surely be present in these chips and the branches that are discarded. Occasional good trees were seen in this area, Thereaiter this Sandalwood was not seen again until some 30 or 40 miles north of Bookaloo. The general impression we received as regards the Sandalwood is that the best trees have been removed from the more accessible areas visited by us, and in some of the more distant ones some of the largest bushes alone had been taken, 143 The Sandalwood is evidently dying out naturally, probably from drought and rabbits; the number of dead trees indicated this. Such death does not seem preventable. We saw no evidence of regeneration at all. No seedlings were noticed, and no half-grown bushes. All were evidently shrubs of many years’ standing, perhaps twenty, thirty, or more years old at least. Rabbits and sheep probably give seedlings no chance at all, On Parakeelya Station a few seedlings of Native Peach were seen coming up in other shrubs, so it is possible that the Sandalwood may occasionally be able to grow from seed in these parts in spite of stock being present. The pullers of Sandalwood only select suitable trees. The more twisted ones are left. It is probable that such trees would supply a sufficiency of seed-bearing bushes to help to maintain the species. It seems clear, if regeneration is to take place, that areas will have to be protected against rabbits and sheep or cattle. It seems important to shut off some small areas for experiment purposes to ascertain what success may attend the planting of seeds, and doubtless arrangements could be made at some of the stations for the adequate protection of such small areas. INFORMATION AS REGARDS SANTALUM LANCEOLATUM. Plate V., fig. 2, and plate VI. As the west shore of Lake Torrens was approached a look-out was kept for this species. At Chance’s Lagoon a small tree with a smooth bark, and very like a Pittosporum, was seen opposite Mr. Greenfield’s homestead, growing up through a Mulga. It was in flower, and the flowers were obtained and proved to be this species, At Andamooka Station this species was found in considerable numbers as small, slender, white-stemmed graceful trees, following along the beds of the dry watercourses, and in general closely resembling the Pittosporum. The trees grow to perhaps twenty or thirty feet high, and have quite an appreciable bole. ‘They were found parasitic on the roots of Mulga, being attached by large haustoria nearly the size of a shilling, presenting a very striking picture. The trees look as though they could regenerate with ease, and numbers of young seedlings were seen, Where trees had been cut or pruned by cattle, coppicing tended to occur: suckering also took place. This species was found usually along the course of the dry watercourses on Andamooka and Arcoona Stations, or im the tableland type of country. It appears that there are several varieties of this species met with in Queens- land. One growing at Cape York, in the extreme north-east, has becn exported to China, ‘he one growing in the south-west of Queensland is probably similar to our South Australian kind. It does not seem to have been demonstrated as yet that this contains oil in commercial quantities. I have the permission of the Conservator of Forests to say that the Director of Chemistry, reporting on a sample of the wood that we had collected, found only 0°22 per cent, of Sandal- wood oil in it, the ether extract being 1-45 per cent.

Sterna and parts of legs with long reddish-flavous hairs, upper surface glabrous, elytral fringe extremely short. Head with crowded punctures, becoming sparse and small in front. Antennae eight-jointed, first joint longer than the four following combined, second stouter and slightly longer than third, fourth with one side narrowed to apex, fifth very short, somewhat produced internally, club with elongate lamellae, each almost as long as the other joints combined. © Prothorax more than thrice as wide as long, sides strongly rounded; with numerous rather shallow punctures, about as large as on head, but much less dense, and becoming rather sparse on sides, Elytra with sides feebly dilated to beyond the middle; with regular but rather feeble geminate striae; punctures about as large as on pronotum but sparser. Pygidium with a feeble median line and with dense and small irregular punctures (almost shagreened). Second joint of hind tarsi slightly longer than first and the length of fifth. Length, 17 mm. Petermann Ranges (unique). Belongs to Blackburn’s first section of the genus, and of the other species of that section H. crinita and erythrocephala have conspicuous prothoracic cloth- ing, H. ruficeps and neglecta are larger and paler, with opaque pronotum, and A, octoarticulata, to which at first glance it appears to belong, has a conspicuous elytral fringe; on the type of this species the fringe is so short as to be practically invisible.

Arnhem Land. CURCULIONIDAE. ACHERRES GRANULATUS Ferg. MacDonnell Ranges, Petermann Ranges. Basedowia, n. gen. Head wide. Eyes ovate, lateral, with fine facets. Rostrum very short, upper surface flattened ; scrobes short, deep, and terminated near eyes. Antennae stout, scape shorter than funicle, most of the joints of the latter briefly cylindrical, club subovate. Prothorax in front about as wide as the median length, base more than twice as wide, with the hind angles produced backwards and embracing shoulders, ocular lobes wide. Scutellum minute. Elytra widely cordate. Meta- sternum short, episterna narrow. Abdomen with two basal segments moderately large. Legs moderately long, front coxae tather widely separated, slightly more than the middle ones, but less than the hind ones; femora rather stout, unarmed ; front tibiae denticulate on lower surface, third tarsal joint widely bilobed, claws equal and close together. Apterous. The rostrum, antennae, and legs Icave no doubt that this genus is allied to Polyphrades, but the hind angles of the prothorax acutely produced backwards and embracing the shoulders, at once distinguish it from all the genera ot the Leptopsides. The elytra are unusually wide and cordate. The separation of the front coxae is unusual in the subfamily, but in Mandalotus is of only specific importance. Basedowia basicollis, n. sp. Black. Densely clothed with greyish scales. Head with minute conecaled punctures. Rostrum much wider than long, with a feeble median line, front with crowded punctures. Prothorax somewhat flattened in middle, sides obliquely dilated from apex to near base, and then drawn acutely backwards, with a feeble median line, with fairly large punctures, crowded together on sides, but less dense in middle. Elytra not one-fourth longer than wide, sides strongly rounded; with regular rows of fairly large punctures in shallow striae, interstices with dense and small punctures. Basal segment of abdomen slightly longer than second, the latter in middle about as long as third 151 and fourth combined, and slightly longer than fifth. Front tibiae rather long and denticulate except near base, middle tibiae shorter and with fewer denticles, hind tibiae unarmed. Length, 6-8 mm. Arnhem Land (abundant). All the specimens are badly abraded, but from the scales left it is evident that in life the insects are densely squamose ; on some specimens from which most Basedowia basicollis, n. sp. of the elytral scales are absent an almost regular row of small setae may be seen on each interstice, but these are normally concealed by scales. The muzzle seems to have a triangular space on which there are no scales, but it is not a shining plate as on many species of Polyphrades and Cherrus. Leprops conrrartus Blackb. Petermann Ranges.

Petermann Ranges, Polyphrades farinosus, n. sp. Black. Densely clothed with small white scales, interspersed with short setae; the tibiae with fairly long hairs. Head with small granules and punctures, longitudinally strigose between eyes. Rostrum longer than wide, sides incurved to middle, upper surface rather widely | concave, with a median carina interrupted near apex by a transverse elevation, but continued beyond it to join a curvilinearly triangular apical plate. Scape not as long as rostrum, four apical joints of funicle strongly transverse. Prothorax somewhat flattened, strongly transverse, sides strongly rounded and widest slightly 152 nearer apex than base; densely granulate. Elytra elongate-subcordate, widest at about basal third, base conjointly arcuate, an obtuse swelling on each side at the basal fourth, its middle on the fourth interstice, suture subtuberculate at summit of apical slope; with rows of large punctures in shallow striae, the interstices multigranulate. Legs moderately long, front tibiae strongly denticulate, the others less strongly so, Length, 15-17 mm. Finke River (three specimens). It is with some doubts that I refer this species to Polyphrades, rather than to a new genus, but the claws are soldered together to near their tips, and the general outlines of the elytra are suggestive of P. tumidulus on a greatly enlarged scalc. The scape is too short for the species to be referred to Cherrus. The head and rostrum are now almost glabrous, but were probably densely squamose on fresh specimens. The scales are unusually dense, and appear at first as if mixed with a whitish meal. Both prothorax and elytra are densely granulate, on the former the granules are sufficiently large to tise above the clothing, but on the latter they are too small to be seen before the scales have been abraded. Polyphrades gibbipennis, n. sp. Black. Densely clothed with greyish and whitish scales, mixed with numerous white, depressed sctae. Ilead with small punctures, base transversely corrugated. Rostrum slightly longer than its greatest width, transversely impressed at base, punctures normally concealed, apical plate large, sharply defined and with small punctures. Antennae moderately long, four apical joints of funicle strongly transverse. Prothorax strongly transverse, sides dilated from base to near apex and then rapidly narrowed to apex itself, densely granulate. Elytra at base no wider than base of prothorax, but sides rather strongly dilated to near the middle, and then strongly narrowed to tips, which are obtusely conjointly rounded; with rows of large punctures, appearing smaller through clothing, third interstice conspicuously elevated on basal fourth only, the adjacent ones also somewhat elevated there, suture slightly thickened at summit of apical slope. Tibiae denticulate on lower surface, the front ones more distinctly than the others. Length, 8-10 mm. Finke River (three specimens). Allied to P. tumidulus, but differs in having the elevated part of the third interstice much more pronounced, and the rostral plate much larger (longer than wide instead of strongly transverse). The elyira are somewhat like those of P. farinosus on a greatly reduced scale, but thé rostrum is very different. The elytra are also somewhat like of those of P. crassicornis, but the prothcrax, rostrum, and antennae are very different. Seen from the side, the base of the third interstice on each clytron appears as the crest of a distinct hump. PoLYPHRADES CRASSICORNIS Lea? A specimen from the Finke River evidently belongs to the same species as three others from the Daly River, which are probably females of P. crassicornts ; they differ from the types of that species in having the elytra longer and with the sides less dilated, and the third interstice on each not elevated near the base, the prothorax also is less dilated ; but all these differences are possibly sexual only.

Head with large shallow punctures, each containing a stout seta. Rostrum stout, fecbly curved, with large punctures close together, but not in rows. Antennae moderately long, two basal joints of funicle about as long as the five following ones combined. Prothorax moderately transverse, sides strongly rounded and notched near apex, which is widely produced in middle, with large punctures much as on rostrum, with a median carina traceable to apex but not to base. Elytra large, base trisinuate and not as wide as widest part of prothorax, each side of base with a triangular projection slightly clasping base of prothorax, near base with a sudden projection supplied with a curved row of subconical granules, the space there much wider than across prothorax; with rows of large but rather shallow punctures, becoming deeper on sides, the interstices with distinct but rather sparse granules, absent from the sides. Mesosternal receptacle rather large, front edge but slightly incurved. Metasternum and two basal segments of abdomen with large punctures, those of the second segment of the latter partly confluent, third and fourth segments very short. Legs long, middle femora rather strongly dentate near apex, the others unarmed, front tibiae long, the apical half strongly curved, hind ones very little shorter but almost straight, middle ones much shorter, third tarsal joint slightly narrower than second. Length, 8-12 mm. Finke River (Dr. H. Basedow), Batchelor and Darwin (G. F, Hill). The posthumeral projections on the elytra are somewhat as on T. ingrata, but the base is very different, and is not, in conjunction with the base of the pro- thorax, so sculptured as to conceal the middle femora from above, the middle femora are quite strongly dentate, but the others are edentate, The species is certainly very different from all other described ones of the genus, and should perhaps have been made the type of a new one. The next species, although not taken by Dr. Basedow, is included here, as belonging to the same genus as T. amplipennis. Tentegia quinquesinuata, n, sp, * Black, antennae reddish. Sparsely clothed.

First joint of funicle slightly longer than second, the two about as long as the five following ones combined. Prothorax moderately transverse, sides strongly rounded, apex less than half the width of base; with coarse crowded punctures, in places granulate-punctate, with a short median carina. Elytra closely applied to prothorax, sides dilated just beyond base, and then rounded to apex, base with five sinuations on upper surface; a wide median incurvature, and two shorter ones, between the base of the third interstice on each elytron and the side; with rows of large punctures, the interstices each with a row of small shining granules, but more conspicuous at the base of the third, fifth, and seventh interstices than elsewhere. Mesosternal receptacle with rather coarse punctures, apical incurvature semi-circular. Metasternum very short. Two basal segments of abdomen with large, deep, irregular punctures, but absent from a median line on the first segment.

In structure it is most closely allied to certain Corticia of the group Ceracea. as Corticium ochracco-fulvwm Bourd. & Galz.

The colour of the young state is nearest to pale tawny-olive of Ridgway’s Colour Standards; of the mature fungus snuff brown. In general appearance it resembles brown forms of Acia fusco-atra, but differs in the marked fasciculate spines, the much looser basal tissuc, and in the abundant deposits of rather large, irregular crystals in the central tissue of the spines. H. fascicularia B. & C., of 156 North America, has similarly fasciculate spines, and is close to this species in structure, but differs in the paler colour and much smaller spines. GRANDINIA Fr.

A very distinct species. The colour is uniformly warm buff, and the texture somewhat loose, giving the plant a pulverulent or tomentose appearance when viewed with a lens. In section, the most marked character is the abundant vesicular bodies in which some of the upward-growing hyphae terminate. These recall the vesicles of Stereum purpureum, and, like those, occur only-in the sub- hymenial tissue. Both basidia and spores are large for the genus. G. australis Berk., in Hook. Fl. Tasm., 1860, p. 257. Syn.: Hydnum pexatum Mass., in Kew Bull., 1901, p. 157. Irregularly effused, closely adnate, membranaceous, at first alutaceous (deep chamois) with scattered granules, finally becoming between raw sienna and buck- thorn brown, very uniform in colour, with crowded granules. The yellowish pigment is soluble in a solution of potassium hydrate with the production of a rich vinaceous tint. Margin indeterminate, narrowly byssoid at first, yellowish or concolorous. Hymenium cracked when dry. Basidia clavate or urniform, 25 X 5 p, with 4 sterigmata 2-~ 5 » long. Spores broadly elliptical, one side slightly depressed, 6 — 7 (— 9) K 4—5 uy. Cystidioles present, but scattered, sometimes fusiform, and pointed, at other times scarcely differing from young basidia, projecting little from the surface of the hymenium, about 30 — 35 X 8 p.

Soc., XIV., 1873, p. 62; Corticium chrysocreas B. & C., in Grevillea, I., 1873, p. 178; Odontia Wrightit (BR. & C.) Burt, in Ann, Mo. Bot. Gard., XIIL., 1926, p. 270. Broadly effused, firm, fairly thick, but not waxy, closely adnate, at first thin, even or more or less papillate, later with distinct spines, becoming much thicker, and, when dry, often cracked into small areolae. Hymenium variable in colour, yellow ochre when young and actively growing, but becoming cinnamon- buff or olive-buff, then avellaneous or wood brown with age. Margin indeterminate, at first buff-yellow or Empire yellow, later concolorous with the hymenium, Subiculum similarly bright yellow at first, but in old specimens the tissue exposed in the cracks often appears white, probably on account of the abundant excretion of crystals from the tissues. The structure in section is very characteristic, but can only be observed well in young specimens. Numerous cystidia are present, both embedded in the tissues and projecting slightly from the hymenium. These are small, shortly fusiform, thin-walled and hyaline at first, 18 — 20 x 6—8 yp. Later the embedded cystidia become strongly encrusted with a deep yellow, apparently resinous excretion, which is soluble in a solution of potassium hydrate with the production of a vinaceous tint. It is insoluble in lactic acid, and the structure is best observed in sections mounted in this medium. The encrusted cystidia eventually occupy considerable space in the subhymenial tissues, and appear to be vesicular bodies, as described by Burt for Corticium chrysocreas. Basidia 15 — 20 & 4-5 p, with 4 sterigmata, 3 » long. Spores hyaline, elliptical, one side depressed, sometimes 2-guttulate 4-5 — 5 (—6) K 2—2°5 a. Basal tissue at first somewhat compact, later the hyphae appear to be loosely interwoven, hyaline, thin-walled 3 — 4 (— 5) » in diameter. The tissue in older specimens contains much mineral matter in the form of crystals, often forming masses in the central tissue of the spines. Hab—On bark. Mount Lofty, South Australia, Cleland “V,’’ May 5, 1928, and “S,” June 23, 1928; Mosman, Sydney, New South Wales, Cleland “D,” May 4, 1919; Brown’s River, Tasmania, Cleland “OQ,” January 30, 1928. 158 Known also from Ceylon, Cuba and the United States. A species very variable in appearance according to age. Young plants are easily recognisable from their brilliant ycllow tints, but older specimens are best detected roughly by treating sections with a solution of potash, when there is always an evanescent vinaceous tinge. The cystidia and spores distinguish it from Grandinia australis. Corticiwm Archert Berk., as to the type specimen, is an old cracked form, with now no yellow visible to the eye. Burt has distinguished Odontia Wrighti from Corticium chrysocreas on the ground that it possesses no vesicles. The type specimen of O. Wrightii was originally a young, thin specimen with few cystidia. It has been, at some time, treated with an alcoholic poisoning solution which has destroyed the yellow colouring matter. Nevertheless, careful examination of sections shows some trace of the embedded, encrusted bodies having been present, and the typical thin-walled conical cystidia occur in the hymenium. There are at Kew recent American specimens which are strongly odontioid in habit, and at the same time show the internal structure which is typical of “Cortictim chrysocreas.” As Archeri is the earliest specific epithet so far traced, it has been adopted for the species. SPECIES EXCLUDENDAE. Grandinia glauca Cooke. This is not a true Grandimia, the spines being fascicles of sterile brownish hyphae covered with deposits of crystals. The fungus may be placed in the genus Epithele, At the same time, the structure is so closely allied to that of species of Grammothele, such as G. grisea B. & C. and G. cineracea Bres., that it is possible that it may be a state of a species of Grammothele, just as Knetffia grisea belongs to G. grisea, according to Bresadola. The Australian plant, however, both the type specimen and a recent collection by Dr. Cleland, shows no trace of the development of either pores or true hydnoid spines, and is certainly distinct from G. cineracea in its longer spores, which are cylindric-ellipsoid, one side depressed, 8-9 & 2—2:5 p. Odontioid forms occur in certain species of Corticinm. Such forms have been observed in C. lividum, C. bombycinum, and Peniephora setigera from Australia, 159 THE GEOLOGY OF ORROROO AND DISTRICT. By Proressor Wacter Howcain, F.G.S [Read September 11, 1930.] Prares VIL. anp LX. The present paper is based on field notes made during various visits to the district, extending from 1905 to the present year. The exposed rocks belong, in part, to the Adelaide Series, ranging from the Glen Osmond lower Slates, as the lowest visible member, and pass up to the lower members of the Purple Slates Series. The respective series are well defined, agreeing perfectly with the type district, The most interesting horizon is the Sturtian Tillite, which is present in the most extensive and impressive development known within the State. The beds follow in anticlinal and synclinal folds, rising in places to considerable eleva- tions, and are sometimes truncated by faulting or subaerial erosion, showing very fine sections. The deformations are chiefly in the form of block faulting and shatter zones. The principal localities herein described are :— ; Page I. Orroroo to Pekina Hill abe S .. 159 Il.

ORROROO TO PEKINA HILL. The township of Orroroo is situated on the Tapley’s Hill Banded Slates and in close proximity to the Brighton Limestone Series. The banded slates have a hard and siliceous texture with cubical jointing and make excellent building stones, They can be studied in the Pekina Creek and along the hillsides. General dip, about 25°-30° E.N.E. The bedding is strongly defined and is sometimes ripple- marked, A zone of intense crush and acute folding can be seen in the creck near the township. About a mile from the township, on the main road to Pekina, the banded slates are seen to dip beneath the limestone series. The latter, in its upper portion, is a strong, blue, crystalline limestone, intersected with veins of calcite, and is underlain by the less pure and more siliceous limestones carrying the peculiar vermiculate-like structures seen on the same horizon to the south of Adelaide. The beds have a strong exposure of about 200 yards across the strike, and their purer beds were at one time worked for flux by the Broken Hill Mines Company. The strike of the limestone is a little to the right of the Pekina Creek, where it passes under the alluvial cover of the plains on the northern side of the township. At the quarry it has a dip E.S.E., and is overlain by a quartzite. The limestone can be easily traced along the strike which crosses the main road to Pekina, about half a mile to the $.S.E. of Pekina Head Station, situated at the extreme south-eastern corner of the Hundred of Coomooroo. Near the home- stead mentioned, a cave exists in the limestone with a perpendicular entrance, which is said to have been explored for some distance without finding a termina- tion. The limestone was followed for about two miles. The banded slates, which 160 rise from beneath the latter, occurring with some slight variation as to texture and dip, are continuous to the Pekina Range. In a small tributary off the main creek the angle of dip rose to 85°. In the same direction, and within about a mile of the range, the dip fell to 5°, and for a short distance appeared to be horizontal. In an approach to the Pekina Range the banded slates give place to the underlying Sturtian Tillite, which will be described in the next section. The more recent geological features, in proximity to Orroroo, include lacustrine deposits laid down in a lake that is now extinct. The sediments line the SkLoway caces 7 PEAKED HILL COOMOOROO WALLOWAY : ERSKINE BLACK ROCK GRANITE TOP * HIGH SLATE HILLa SPRING x, DEPOT HILL QUARRY IN BANDED SLATE BLACK ROCK PLAIN MORGAN BLACK ROCK RAILWAY STS SPRINGS \ a 4 MUCRA HILL ecm, ‘ ‘o 5 ‘ Fig. 1.

PEKINA RANGE AND THE BLACK HILL RANGE. (Fig. 2.) The two ranges run, approximately, parallel to each other. Pekina Range passes through most of the Hundred of Pekina, in a north-easterly direction, and ends near Pekina Ilill, the highest point in the range, in the Hundred of Coomooroo. The line of section taken was from Pekina Hill, following a south- 161 easterly direction through the Black Hill Range to the scarp of the latter, facing east, at a point about four miles to the southward of Orroroo. The Black Hill which gives the name to the range, must be distinguished from the Black Rock, which gives its name to a range on the opposite side of the plain. The section is in the form of a well-defined geosyncline, [See fig. 2.] The present section begins where Section I. ended, but at a divergent angle towards the south-east. In rising to the Pekina Range, a rubbly quartzite was met with passing into tillite grits, followed by a normal tillite which forms the most of the range, including Pekina Hill, where the observations were made. The erratics were not so numerous as seen in some exposures, but one very strongly striated boulder was obtained. Moody’s Creek, which takes its rise in the northern portions of the Hundred of Black Rock Plain, after crossing the south-western angle of the Hundred of Walloway, makes its junction with the Pekina Creek at the south-eastern angle of the Hundred of Coomooroo, This creek supplies the best available section across the strike of the beds, and was, therefore, followed to its head. The bed of the creek is, mostly, in the Purple Slates Series (having a bluish tinge), and carrying thin quartzites. The beds roll in a succession of short anti- clinal and synclinal folds, with the upper limits of the Brighton Limestone exposed in the nip of the folds. In Section 186 [Hd. of Black Rock Plain] there is a patch of limestone 80 feet wide, probably brought in by a fold. PEKINA HILL BLACK HILL © irrabera Creek Moody's Creek Fig, 2. Geological Sketch-Section of Geosyncline connecting the Pekina Range and the Black Hill Ranges. [Six miles.] (a) Purple Slates Series; (b) Limestone (Brighton Series); (c) Banded Slates (Tapley’s Hill Series); (d) Sturtian Tillite; (c) Glen Osmond Upper Slates. The Irrabera Creek takes its rise near the head waters of Moody’s Creek, and flows in a northerly direction. The Irrabera, in Section 186, exposes the junction between the Brighton Limestone (which is strongly developed on its western banks) and the Tapley’s Hill Slates which occupy the eastern banks. Following an easterly course, the last-named slates form the rise to the Black Hill, which consists almost entirely of beds of this horizon, ending abruptly in a steep scarp bordering the plains. About a mile to the southward of the point reached, at the base of the scarp (about the dividing line between Sections 182 and 147.£), the tillite is exposed in the banks of a small creek, giving a section showing the junction of the tillite with the overlying Tapley’s Hill Banded Slates. The section was covered by the talus slope [rom the hills, and would not have been seen had it not been for the creek’s action in eroding the talus. The tillite is evidently exposed at the base of the range, in places, as by traversing the flats further to the northward, numerous fragments of the tillite were observed scattered over the paddocks mixed with other detritus. 162 Ill, THE MUCRA RANGE. (Figs. 3, 4 and 5.) The Mucra Range, following a north and south direction, rises gradually from the plain two miles to the westward of Black Rock Railway Station. Instead of calling it a “range.” it would be better described as a plateau having a scarp face towards the east. The ground geologically examined, and now described, is situated about five miles to the southward of the section shown in fig. 2. It covers an area of about three miles in an east and west direction, extending from the alluvium of the plain on the east, to a little beyond Mucra Hill on the west; and about one and a half miles in a north and south direction. Although of limited area, it is of more than ordinary interest on account of the deformations to which the area has been subjected by faulting, crush zones, displacements, and repetitions of the beds. It is also of interest on account of the exceptional extent to which the Sturtian Tillite is developed in surface features. The vertical range in the geological succession is slight, passing up from the slates that underlie the Glen Osmond-Mitcham Quartzite, to the Tapley’s Hill Banded Slates that overlie the tillite. Three creeks intersect the area by which shallow sections of the beds can be obtained. The Mucra Springs Creek is the most important, and is fed by springs that have their outlet near the head waters of the stream. The springs have a constant flow and are incidental to the faulted condition of the ground. Sweet’s Creek (or Tank Creek) is situated a little to the southward of the Mucra’ Springs Creck, and unites with the latter at a lower level. his creek is also fed by a spring. The third creek is McNaughton’s Creek, situated on the northern side of the Mucra Springs Creek. The three creeks are lost by absorption in the alluvium of the plain at the base of the range. Two systems of faulting can be recognised within the area, A major fault has an east and west direction, while several other faults have a strike north and south, being, approximately, at right angles to the major east and west fault. The latter is opposed to the general strike of the beds, and is, therefore, a dip fault which breaks the continuity of the beds, while those in a north and south direction form strike faults, which repeat the beds. The prevailing dip is westerly, or south-westerly, sometimes at a high angle, and is, in a few cases, locally reversed. In taking a general view of the field, it is seen that ihe great E. and W. dip fault has thrown the whole field on the northern side of this fault to the eastward, while several strike faults have repeated the beds, once on the southern side and twice on the northern side of the main fault. This can be seen in figs. 4 and 5. There is, therefore, only one main quartzite horizon in the field, split up into four sections with some secondary occurrences that will be explained later. The important east-west fault divides the field into two parts, a southern and a northern section, which require to be considered separately. Description of the Geological Field. (A). GEOLOGY OF THE-SOUTHERN SIDE OF THE DIP FAULT. (a). VTapiey’s HILL SLATE. The main road between the Black Rock township and Wepowie Creek passes over a col in the range, a little to the southward of Mucra Hill. The country between the latter and Wepowle Creck is level and cultivated. the surface soil being derived from the decomposition of the Tapley’s Hill Slates which overlie the tillite and form the highest geological horizon within the area under considera- tion. The slates arc well exposed along the banks of the creek above mentioned, passing up into the Brighton Limestone. ee V3 K HA Banded Slates ( Glen Osmond (Tapley's Hill Series) Upper Slates Glen Osmond Glen Osmond + The “Sugar Loaf’ Quartzite Lower Slates Fig, 3.

SvurTIAN TILLITE, To reach Mucra Hill, the Wepowie road is followed to the top of the rise and, at a five-road junction, the north road is taken, followed by the first turn to the east to Mr. MacMahon’s homestead in Section 19, Hd. of Black Rock Plain. Near the residence mentioned, a hill, situated in a gap of the range, shows prominent exposures of tillite in a line of outcrop that is continued to Mucra Hill (a trig. station) with fine exposures of a typical kind, which, by the eye, can apparently be traced for miles in a northerly direction. The tillite has a great spread to the eastward, reaching to the wire fence that follows the edge of the plateau, having a width of a little over half a mile. The ground is more or less under cultivation, with ridges of the tillite rising in places and patches, some of them several acres in extent, so thickly strewn with erratics as to make ploughing impossible. The erratics reach a size up to six feet in length, too heavy to shift, but near the boundary, at the edge of the plateau, some have been dragged to the fence. Near the centre of the ground there is a ridge of tillite with an apparent dip to the north-west at 70°. The base of the tillite, on the southern side of the main east-west fault, is near the edge of the plateau, on the eastern side of the boundary fence, where a small quartzite occurs. This latter may prove to be either the upper limits of the underlying slate, or a lenticle in the tillite, near its base. Not much attention was devoted to the erratics, but those seen were mostly quartzites and included some porphyries; one limestone boulder was recognised, granite erratics were apparently rare. (c}). SLATES BENEATH THE TILLITE (= GLEN Osmonp‘) Upper Srares). The ground falls rapidly from the edge of the plateau towards the east, forming an exposure of the Glen Osmond Upper Slates in a thickness of about 150 feet. These slates have a laminated structure and a bluish-black colour. Dip, W. 20° N. at 60°. (d). Tue Quartzire (= GLEN Osmonp Quarrzire). The slope of the ground from the edge of the plateau, cutting the basset edges of the slates, just described, becomes arrested by the presence of a strong quartzite which rises above the normal level in a very broken ridge, having a strike, approximately, north and south. The outcrop is very sharply truncated by the east-west fault, showing a bold scarp to the headwaters of the Springs Creek, 100 feet in height, with the faulted tillitc transverse to its base. All the main quartzites within the area are of precisely similar type—fine- grained, mottled, and extremely brittle, The latter feature is no doubt the effect produced by the powerful earth movements which have occurred within the area. The stone splits freely under the hammer, fracturing in all directions with many smooth and slickensided faces. The evidences of fracture, from crush, can be seen in the general rock structure by groups of cracks and open spaces in the main portions of the stone. This brittleness is especially seen in the great isolated monolith that goes by the name of the “sugarloaf,” to be described later. (e). SLATES BELOW THE QuaRTzITE (— GLEN Osmonp Lower SLaTEs). These slates follow in regular order below the quartzite. They can be dis- tinguished from those above the quartzite by the occurrence within their limits @) In the type district, the quartzite, with its attendant upper and lower slates, occurs both at Glen Osmond and Mitcham, forming two anticlines, separated by a syncline by which the quartzite dips below the surface, to reappear in a return fold at Mitcham, so that the beds in these contiguous localities are on the same geological horizon. 165 of calcareous zones that carry more or less cherty nodules and layers. This is a well-marked feature of the beds as developed near Adelaide, and is distinguished as the “blue-metal” limestone. Its occurrence in the present section is a good guide to the particular horizon represented. Further references to the subject will be found below. The slates just defined are determined by a strike fault with a north and south direction, which had the effect of repeating the beds, as described in the next paragraph, Repetition of the Beds (Southern Side), (Fig. 4.) (1). Faulted Upper Slates.—The strike fault mentioned in the preceding paragraph had the effect of a down-throw by which the slates above the quartzite, as well as the quartzite itself, were once more brought within the limits of the section, and the upper slates were placed unconformably against the lower slates. (2). Faulted Quartzite—This outcrop of the main quartzite makes a very strong and high ridge with a strike roughly accordant with the one to the west- ward, of which it is a repetition. On the northern side it is cut by the great fault that runs in a line with the Springs Creek, and to the southward its elevated out- line can be traced by the eye as extending for several miles.

[One and a halt miles. ] (c) Banded Slates (Tapley’s Hill Series); (d) Sturtian Tillite; (eg) Glen Osmond Upper Slates; (f) Glen Osmond Quartzite; (g) Glen Osmond Lower Slates; (4) Alluvium of the Plain, In the dislocation and sheering to which these rocks were subjected, the quartzite on the westward side, near the fault plane, was broken, carried forward, and left out of alignment with the main mass. There are two such isolated frag- ments. One of these is situated on the right bank of the Springs Creek, about mid-distance between the two main outcrops and is locally known as the “sugar- loaf.” It is a very remarkable object—an isolated monolith, in angular outline, vertical walls, and considerable elevation, covering an acre of ground. It appears to have been severed from its bed in the western outcrop, dragged along the fault plane, and left stranded in its isolated position, A trail of broken and mashed rocks can be traced from the base of this castle-like rock in a south-easterly direction. The other illustration of these isolated fragments occurs on the western side of the eastern outcrop of quartzite and runs parallel with the latter. [See figs. 3 and 4.] It is separated from the main quartzite by about 100 yards, and is almost, at its thickest part, a rival in size to the latter. It is lenticular in outline, with a length of about 20 chains, attenuated at cither end by decreasing thickness and brecciated rock material, running out before reaching the Springs Creek, on the northern side, and a small ercek on the southern. It appears to owe its origin to a secondary strike fault which has duplicated the quartzite at close quarters and, for a limited length, in lenticular form. 166 The southern extremity. of this lenticular quartzite reaches the northern branch of Sweet’s Creek, and a few broken and mashed stones can be traced across the creek, where it ends. About 100 yards further up the creek from this point there is a break in the slates; the dip, which is normally south-westerly to west, is changed to the south-east, and a little higher up it is reversed to the west-north- west at 55°. This probably represents the position of one of the strike faults that has repeated the beds. (3). Faulted Lower Slates—These beds are conformable with the main quartzite outcrop under which they dip, and with which they are united im one and the same faulted block. They also include the “blue-metal” limestone and cherts proper to this bed. The slates follow the slope of the ground, and are ultimately obscured by the alluvium of the plains. (B). GEOLOGY OF THE NORTHERN SIDE OF THE DIP PAULT. (Figs. 3 and 5.) The geological features on the northern side of the great dip-fault are more varied and complex than those on the southern side of this fault, involving a great throw to the eastward and a more extended repetition of the beds. MUCRA HILL mater? Wis Fig 5, Geological Sketch-Section, No. 2, of the Mucra Springs Area. The Section cuts the main East-West Fault obliquely.

FauLttep TILiire (Upper Exposure). The fault, above mentioned, enters the valley where the central stream of the Springs Creek takes its rise, and for some distance the creek follows closely the line of faulting. At the head waters the division between the slates, on the right bank of the creek, and the tillite, on the left bank, is quite sharp. On the bank side, not far from the fault plane, a large quartzite erratic is set in the tillite, which measures 5 feet 6 inches by 3 feet 6 inches by 3 feet 6 inches. The main body of the tillite is thrown about 25 chains to the eastward of its former boundary—that is, to about mid distance between the truncated quartzite and the “sugarloaf” that are situated on the other side of the fault plane. It is here ended by a strike-fault having a direction a little east of north. The fault plane carries much quartz, a quantity of micaceous iron and fault-rock that is dark-coloured and very siliceous, passing to chert in places, This north-south fault crosses the creck to the southern bank; the hard siliceous rock (forming the crush-rock of the fault plane), by its superior resistance to stream crosion, forms a waterfall, about six fect in height, while the fault dies out, apparently, against the east-west dip-fault on the southern side. 167 (b). SLATES BENEATH THE TILLITE. These are well exposed in the creek below the waterfall caused by the north- south fault. They show smooth bedding planes with a dip at 45°, and are situated a little above the “sugarloaf.” Just below the latter, in the creek, the slates are much disturbed and mashed, having a dip of 65° to the west. On the right bank there is an old washout that has heen filled with layers of sediment that have undergone induration so as to resemble older rocks, and, at first sight, might be regarded as an overthrust on the slates. At one spot, slates and thin quartzites are in vertical position with a strike nearly north and south, being divergent from the normal, north-west. The position of these slates—between the tillite and the quartzite—suggests that they represent the Glen Osmond Upper Slates, but the evidences of faulting at the eastern margin of the tillite, and, probably, near the “sugarloaf.” prove considerable disturbances that are difficult to define. (c). Tue NorrtHern Vauttep Quartrzite, No. 1. The quartzites at the “Springs” are of peculiar interest. In a casual observa- tion the quartzite on the southern side appears to cross the creek and ascend the hil! on the northern side, but this is not the case. The respective outcrops certainly represent the same geological horizon but, stratigraphically, they are a long way out of alignment with each other. The east-west dip fault divides them. The true alignment of the northern ridge of quartzite is not with the quartzite that faces it on the opposite side of the creek, but with the truncated limb that appears on the southern side of the fault a quarter of a mile higher up the stream. The strike of the two beds of quartzite at the ‘‘Springs’’ is not exactly coincident, as the northern branch meets the creek about the thickness of its own diameter (50 feet) to the eastward of the southern branch, The northern line of exposure follows a strike to the north-west, curving round, and crosses McNaughton’s Creek, about half a mile distant. There appears to be a chain of springs in the bed of the creek, the most important being the one marked on the map near the junction of the two opposed quartzites, where the remains of a drinking trough can be seen. The locality is very much disturbed. Near the fault, in the creck and on the sides of the hill, the quartzites are reduced to a crush-breccia, the same features extending in a south-westerly direction, taking in the trails associated with the isolated frag- ments of the “lenticle’” and “‘sugarloaf” described above. (d). SLATES BETWEEN THE QUARTZITE AND Lower TILLITE. In a normal succession (with a westerly dip) the slates, as underlying the quartzite, may be regarded as the equivalent of the Glen Osmond I.ower Slates. ‘he beds, which have an exposure of about 250 yards, are much disturbed and broken, mostly pitched at a high angle, sometimes vertical, or even reversed, with a strike directed east and west, and a dip, south. In this disturbed area, one large picce of slate was secn to be strongly grooved and slickensided. The slates are separated from the underlying tillite by a fault plane, and there is some reason to think that the tillite overrides the slates. The line of fault is marked by the presence of ironstone, with a strike N.W. and S.E.. and can be traced for a considerable distance. (ce). Vauttep Titiite (lower Exposure). The position of the repeated tillite in the section gives evidence of a very considerable downthrow on the eastern side of the fault. In the normal order of succession the Tapley’s Hill Banded Slates should rest on the tillite, but instead 168 of this the Glen Osmond Lower Slates have that position, while the Glen Osmond Quartzite and Upper Slates are cut out, but reappear in their normal position later in the section (see fig. 5). ‘The tillite has a surface exposure of about 500 yards across the strike. In its basal portion it is dark-coloured and siliceous, but throughout the greater portion it is buff-coloured, in which the darker coloured erratics, worn down by the stream action to a level, show out very conspicuously against the lighter coloured matrix. At about half distance along the surface a boulder, fixed in the tillile, measures 6 feet by 4 feet, consisting of reddish, siliceous, quartzite, much veined with quartz and, in places, showing false-bedding. ‘The tilhte is limited on its southern side by faulting, but, on the northern, extends in that direction to, at least, McNaughton’s Creek. Taking in the faulted portions, the tillite has a spread across the strike of a mile and a half, one of the largest areas for this particular rock within the State. (f). SLATES BELOW THE TILLITE, Rising from beneath the tillite are bluish and dark-coloured slates with a dip S.W. at 50°. They correspond to the Glen Osmond Upper Slates, and have am exposure of about 250 yards. (g). NorrueRN FAauLtep QuartziTe, No. 2. In descending order from the last-named slates, is a repetition of the same quartzite that outcrops higher up the valley. Its position can be fixed in Sec- tion 132, just above the junction of a tributary on the right bank, which has a course almost parallel with the main stream. The quartzite strikes the creek tangentially, and from its being partially on its strike gives a section 160 yards in length, The dip is W.S.W. at 15°, with a N.W. strike. The outcrop forms a ridge which is directed towards the main range about a mile distant. It is not seen outside the creek on the right bank, as on that side the alluvium of the plain obscures outcrops. The lithological features of the quartzite are exactly similar to those already described with reference to other exposures of the same rock. (h). SLATES BELOW THE TAULTED QuARTZITE, No. 2, Rising from beneath the quartzite (just described), in Section 132, near the north-eastern angle of Section 149&, are slates corresponding to the Tower Glen Osmond horizon. They can be seen in the creek bed, for about 100 yards, with a dip S.W. at 40°, They are much weathered and bleached, as they form the margin of the older rocks as the latter disappear under the alluvium of the plain. McNaughton’s Creek. This creek has a parallel direction with the Mucra Springs Creck, situated on its northern side, and at a distance of about half a mile. The tillite which is seen in the head waters of the Mucra Springs Creek (on the western side of the north and south fault) continues to McNaughton’s Creek, in its upper reaches, Dip of beds, 5.S.W. at 45°, The boundary fault on the eastern limits of the tillite, also goes through to McNaughton’s Creek, on the same line of strike. The fault zone is marked by ferruginous quartzite and ironstone, which has an apparent dip to N.E, at 75°. Just below the fault plane, blue slates show in the creek with a dip S.W. at 40°. ‘The thick quartzite, in its eastern throw, follows the ridge from the Springs, crosses the creek and makes a prominent feature on the north- western side of the creek, having a dip S.W. at 36°. Then follows a thick blue slate with thin beds of quartzite, dip S.W. at 35°; under which rises another thick 169 quartzite, and this again underlain by more blue shale which continues to a junc- tion with the tillite in its second or eastern occurrence. The latter is a quarter mile in breadth and continues northward to McNaughton’s boundary fence, indicated on the map by the public road. ‘The tillite is underlain by laminated slates, dipping S.W. at 60°, and these again underlain by quartzite. Sweet’s Spring Creek (or Tank Creek). (So named from a stone tank that was formerly supplied by means of a pipe led from a spring higher up.) The Creek is situated nearly half a mile to the southward of the Mucra Springs Creek, with which it unites at a lower level. Rising to the foothills are outcrops of slate and buff-coloured limestones with chert, up to six inches in diameter. A ferruginous quartzite outcrops on a low hill with dip W. 20° N. at 60°. In a small creek, behind the ruins of Sweet’s house, slates strike 5. 20° W. in vertical position, or slightly to the west. Two hundred yards above the first outcrops in the creek there is a crush-rock, 42 yards wide, in the creck. It shows no regular bedding, Parallel lines may be recognised in short distances, but the great mass of the rock is shattered. A break of 50 yards occurs in which no rocks are seen, following which are slates, showing a small fault plane in beds much broken and penetrated by small quartz and mineral veins. Anticlinal folding gives reversed dips E.N.E. and W.S.W. Small water- falls occur in the creek, above which is a quartz reef, 4 feet 6 inches in thickness, penetrating slates with Fe,O,. A little higher up, close to the road leading to the Spring, the slates have a dip W. at 45°, which increases to 64° in the direction W. 20° N., becoming vertical and reversed near the Spring. The water issues at the junction of the slates with thin quartzites, the latter having a dip W. at 80°. These quartzites are followed, in ascending order, by slates and buff-coloured dolomitic limestones which are seen on the rise to the plateau, with an important quartzite 60 feet thick near the crest. Section Taken Along the Old Post and Wire Fence. A fourth traverse of the range was made by following the “post and wire fence,” marked on the map, that passes up from the township to the Mucra Plateau. The route was parallel to those already described, and half a mile to the southward of Sweet’s Spring Creek. Some fragments of chert were observed on ploughed land in a paddock before reaching the stony rise. Near the dividing line between Sections 131s and 149 a mallee scrub marks the first rise in the foothills. Here the first exposure of rock is seen as decomposed laminated slate (or shale), carrying bands of black chert in situ, evidently the parent rock from which the distributed fragments met with at a lower level were derived. Higher up, near the top of the next ridge in the foothills, a number of pros- pector’s holes in the slate afforded some evidences. They showed the slates to be very fissile and split with smooth faces. In the excavation the dip showed W, at 50°. Further on, the dip changed a little to the north of west, and at a higher angle—in places, apparently, vertical. At some horizons calcareous zones occurred. No alteration of geological features occurred till the path cut through the first high ridge with a quartzite, about 50 feet in thickness. This quartzite is the same as the quartzite cut in the Mucra Creek section by the east-west fault at the “Springs.” Superior to the quartzite, last mentioned, there are more laminated slates (or shales) and on the rise towards the watershed marked calcareous horizons are scen in the slates forming an earthy-bluish-impure limestone, divided up into layers about six to twelve inches each; some of a blackish colour similar to that of the 170 “blue-metal limestone” near Adelaide, which occurs there in the slates between the Thick Quartzite [Black Hill and Stonyfell| and the Glen Osmond Quartzite. Near the summit of the scarp, forming the water-parting, there is another important quartzite which forms the southerly extension of the quartzite which is truncated by the east-west fault at the head of the Mucra Springs Creek. Rest- ing ou this quartzite is a flaky slate, about 50 feet in thickness, which separates the quartzite from the tillite that immediately succeeds it in position. The bed correspgnds to a similar one that separates the quartzite from the tillite as described above in its northern extension. IV. THE BLACK ROCK RANGE, (Fig. 6, pl. viti., and pl. ix., fig. 1.) This range, situated 168 miles to the northward of Adelaide, and about four miles in length, is the most conspicuous highland for many miles around, rising steeply from the level of the plain. The sky-line of the range forms a jagged contour arising from the differential weathering of its geological elements, as well as the block-faulting to which the range has been subjected. The beds are included in the Adelaide Series, and the vertical succession extends from the Glen Osmond-Mitcham Lower Slates to the Tapley’s Hill Slates, with the inter- BLACK ROCK DEPOT HILL GRANITE TOP HIGH SLATE HILL Fig. 6, Geological Sketch-Section of the Black Rock Range.

Horizon: T.ower Slates of the Glen Osmond-Mitcham Series.‘) The Black Rock, the highest point of the range, has a trig. cairn on its sum- mit with the official record of 2,800 [eet above sea level. It is situated a little over 11 miles, in a direct line eastward, from the township of Orroroo, and rather less than that from the Black Rock Railway Station. The base of the hill is estimated to be 1,680 fect above sea level, giving the hcight of the hill, from its base, as 1,120 feet. The most accessible path by which to reach the height is on the southern side of the hill, wp what is known as the Granite Creek (to be referred to presenily) ~—a side that has been thickly covered with sheoak trees, but which are now nearly all dead from the effects of the parasitic plant, Loranthus. ©) The so-called “slates” of the Adelaide Series might often be better designated shales, as they frequently show a fine lamination and split on the bedding planes. The same beds, in other situations, develop a coarse cleavage and split more readily at an angle to the bedding. As it would be inconvenient to call the same bed in one place a shale and in another a slate, it is better to adopt a single term, although the particular bed might be more appropriately called a shale. 171 Black Rock is shown on the map of the Hundred of Erskine, placed on the northern boundary of Section 24. It is composed of a very compact slate, of a dark-bluish colour, finely laminated and very uniform. The bedding is marked by numerous very regular and parallel lincs, strongly coherent but at intervals fissile by which the rock is divided into flags, a few inches in thickness, and is sometimes massive. On the southern side of the hill the beds show a dip slope of about 40° in a westerly or south-westerly direction, decreasing im the angle of dip towards the summit. At the crest, the rock, bared to the weather, has developed a rough kind of cleavage at a high angle, not seen in less weathered portions of the rock. At first sight this might be taken as a change in the angle of dip, but careful observation shows the bedding lines as transverse to the cleavage planes. The northern face of the hill is a very pronounced fault scarp, very steep, with a ledge a short distance down from the crest, and a raised broken ground at the base, several hundred feet below. The bed of quartzite, which caps Granite Top, on the southern side, although absent from the crest of the Black Rock, is seen on the faulted segment, having been thrown down in conjunction with the underlying slate. (6). GRanire Top. Horizon: Glen Osmond-Mitcham Quartzite. A very strong and siliceous quartzite overlies the Black Rock Slates, and in consequence of an eroded gap in the slates causes the quartzite to take the form of a lofty and scarped face not much below the height of Black Rock. The popular name of “Granite Top,” although a misnomer, as there is nothing of granite about it, has become stereotyped by the name having been placed on the Government Map, in Section 24, Hundred of Erskine. Its striking prominence is due to its resistance to weathering, coupled with the stream action of the Granite Creck, which takes its rise on the south-eastern flanks of Black Rock, having cut a gap between the quartzite and the slates near the summit, and then cutting through the quartzite at a lower level, hy which the latter caps the valley on both sides, the dip slope giving a reduced height on the western side. The quartzite is a light-coloured, siliceous, and piebald stone by the presence of small flakes of white felspar, a very characteristic feature of the Mitcham Quartzite. The original quartz grains, by metamorphic action, have been blended and fortified by introduced silica in optical continuity that approaches the struc- ture of a quartz-rock. The rock is massive and has a slight tendency to spheroidal fracture. The thickness of the bed is estimated at about 60 feet, but this is uncertain, as the base of the bed is obscured by talus. ‘The bed has a slight pitch downwards as it passes under the overlying slates of the “High Slate Hill” at the level of the road and creek [see pl. ix., fig. 1]. (ce). Hien State Hint, Horizon: Upper Slates of the Glen Osmond-Mitcham Series. This hill, shown on the map as situated in Section 7n~ (Hd. of Erskine), is in a direct line with Black Rock and Granite Top, following a south-westerly direction. It is an isolated, pyramidal hill, about 600 feet in height, with steep faces on all sides, especially on the north side which shows the basset edges of the slate rock. On the descent from the Black Rock, a course was shaped around the eastern’ base of the hill to its southern side. The beds show the same features of an earthy slate as seen in the corresponding horizon in the type district. The steep- ness of the hill on its southern face is caused by the great downthrow of the glacial beds on that side, the fault having carried down the underlying slates with the tillite, making an unconformable junction between the two. 172 (d). Stuart’s Looxour anp Drror. Horizon: The Sturtian Tillite. The site is marked on the official map as “Depot Hill” [Sec. 135, Hd. of Morgan]. The local statement is that it formed a camping ground and lookout for the explorer, J. McDouall Stuart. It is probably correct, but the latter begins his “Journal” from a position further north, The site forms a narrow valley at the head of which are two peaks, the higher one known as the “Lookout,” and the other, which is slightly lower, as the “Depot Hill.” Near the head of the valley is a permanent spring of good water which it is assumed formed the camp- ing place. There is an extraordinary development of the tillite in the north-western portion of the Hundred of Morgan. ‘The beds are exposed on the western boundary of the Hundred in Sections 101N and 101s, and continue in a gradually rising range (or spur) for a distance of six miles, reaching a maximum height in the Depdt and Lookout peaks [see pl. viii., figs. 1 and 2]. Towards the head of the valley (in the neighbourhood of the spring) the outcrops are very massive and rugged, rising to a height of about 500 feet, formed of tillite throughout. The erratics are numerous, mostly sharply angular, and were observed up to two feet in diameter. They consist mostly of quartzite, with a good number of granites, metamorphic rocks, basic igneous rocks, and one limestone example was seen. Near the head of the valley the tillite extended up the south-eastern elevation, as well as on the north-western, passing under kaolinized slates. The:line of' junction between these two beds crosses the valley diagonally, passing over to the north-western side. On rising to the crest of the Depot Ilill, it was seen that the range on its north-western side was bounded by an almost vertical scarp caused by a down- throw on that side comprising some hundreds of feet. This broken segment extends northwards to the limits of the High Slate Hill, as stated above, having a length co-extensive with the range (six miles or more), and a breadth, reaching the southern flanks of the High Slate Hill, of one and a half miles, the most extensive exposure of the Sturtian Tillite, in one mass, known within the State. (e). Posr GiactaL SLATEs, Horizon; Tapley’s Hill Banded Slates. About three miles to the south-westward of the Depot Hill, on the flanks of the tillite spur, a quarry has been worked in the overlying slates by Mr. Lloyd Haynes, on his farm in Section 121, near its northern boundary. The quarry is in kaolinized banded slates, having a dip E.S.E. at 35°. The rock splits easily on the bedding planes and shows ripple marks on some faces. The tillite is exposed on the rise behind the quarry. At about 100 yards in the direction of the dip a quartzite a few fect in thickness is included in the slate, and froim its superior hardness forms a slight elevation in the contour. With a change in the geological nature of the country the surface, to the southward, assumes a flat and featureless aspect. It appears that the Depdt spur is really a faulted block as distinct from the main range, the latter having a dip to the west or south-west, while the Depot ‘spur shows a dip to the E.S.E., the result of the great downthrow being to give the spur a tilt to the eastward. The tillite dips under the alluvium on the eastern side of the Orroroo plains, and reappears at the base of the ranges on the western, as described above, in a distance of six miles. 173 V. THE PEAKED HILL RANGE. (Fig. 7, and pl. ix., fig. 2.) The Peaked Hill takes its name from its shape, rising on all sides to a central peak. It is a conspicuous object when viewed across the plain from Orroroo,’ a distance of eight miles in a straight line, and is about the same distance from the Depot Hill in a north-westerly direction. Its position on the map is close to the western boundary of the Hundred of Erskine, Section 69, and about mid-distance between the northern and southern limits of the Hundred [pl. ix., fig. 2]. The beds exposed, in ascending order, are: (e) the Glen Osmond Upper Slates; (d) the Sturtian Tillite, which takes in most of the hill, divided by a quartzitic zone into two sections; and (c) the Tapley’s Hill Banded Slates, which pass into low ground. The hill owes its prominence entirely to the presence of the tillite and quartzites which possess greater resistance to weathering than the associated slates. The dip is northerly, and, as this is opposed to the dip of the Black Rock Range, it probably forms part of an anticlinal fold of which the respective prominences are the complementary curves. Fig, 7. Geological Sketch-Section of the Peaked Hill. ‘(c) Banded Slates (Tapley’s Hill Series); (d) Sturtian Tillite; (+) Quartzite in Tillite; (¢) Glen Osmond Upper Slates. The range, of which the Peaked Hill forms a part, continues in a northerly direction through the Hundred of Erskine to the boundary of the Hundred of Yalpara, where it subsides to lower ground. Following on the same line of strike, in a north-north-easterly direction, a further exposure of the tillite was observed in the Hillpara Creek, at a distance of nine miles from the Peaked Hill. The bed of the creek, as well as the adjoining hillsides, consist of the Sturtian Tillite. One granite erratic in the bed of the creek measured three feet, VI. WALLOWAY AND OLADDIE. (Figs. 8 and 9.) The Walloway Railway Station is situated seven miles to the northward of Orroroo. The adjacent township is marked “Rye” on the official map. As the position is on the edge of the alluvial plain geological sections are of a restricted ' kind, being limited to the railway cutting, near the railway station, and the banks of the Walloway Creek. The latter takes its rise on the western slopes of the Oladdie Hills, near Eurelia, and after flowing in a south-easterly direction for about ten miles (mostly in a course adjacent io the railway), it takes a sudden turn to the east and is soon lost in the plains. From the limited amount of rock expostires the vertical range of the beds is restricted to few horizons. The dominant geological feature of the locality is the Brighton Limestone Series. To the southward the latter occurs near Orroroo, as described above, and in a north-north-easterly strike, crosses the railway line, a little beyond the Walloway Railway Station, and intersects the Walloway Creek, immediately adjoining, where an interesting section of the beds ‘cccurs. | Fig. 8.] 174 The lowest member of the Adelaide Series, seen in the creek, consists of the Tapley’s Hill Banded Slates. On the eastward side they are cut off by the alluvial sediments of the plain. In a westerly direction they continue for about a quarter of a mile at a high angle of dip, having an average pitch of 75°, reaching the vertical in places. ‘towards their upper limits they become calcareous, but more or less siliceous, showing the “vermiculate” structure, often seen at this horizon, and are sometimes earthy. These impure beds pass up into more definite lime- stones, as usually occurs in the Brighton Series. The limestone is generally of a bluish tint, or nearly black, in colour, often carrying veins of calcite, and, in places, becomes of a pinkish or buff colour. The calcareous zone continues for several hundred yards. In the railway cutting the limestone is exposed for about 80 yards with a dip W. 10° N. at 83°. The limestone ends in the creek quite suddenly with a dip W. at 78°, and is followed by an alluvial bank for about 100 yards, at the end of which the Purple Slates Series makes its appearance. Passing through the culvert under the rail- way line, and following the bed of a small tributary to the main creek, a better view of these beds can be obtained. Here the strong limestone ends abruptly with a small scarp face and, after a few yards of talus, the overlying Purple Series is seen with thin reddish quartzites and an arenaceous limestone, followed by reddish laminated slates that have a dip W. at 72°, the section being closely similar to the Purple Slates Series in other parts of the State. Fig. 8. Geological Sketch-Section, Walloway Creek, (a) Purple Slates Series; (b) Limestone (Brighton Series); (c) Banded Slates (Tapley’s Hill Series), Within 100 yards from the main limestone a strike fault cuts off the purple slates and brings to the surface the laminated and banded slates of the Tapley’s Hill and Brighton Series. The beds, which at first have a low dip to the east- north-east, change a little higher up to west-north-west at an angle of about 15°, and, finally, at a mile distance, pass under the second outcrop of the Brighton Limestone. Taken as a whole, the section reveals an anticline broken by a fault with a very considerable downthrow. GEOLOGICAL SECTION BETWEEN WALLOWAY AND EuURELIA. The railway between the two stations mentioned runs so close to the margin of the Walloway Creek that it is easy to observe the geological features exposed in the creek from the train while in motion. In this way the following observa- tions were made. The most striking feature seen in the seven miles’ journcy between the two places was a further fault and repetition in the Brighton Series, as shown in the following sketch-section, [Fig. 9.| After passing over the Purple Slates Series for some distance, the siliceo-calcareous beds of the upper part of the Tapley’s Hill horizon were in view, showing a dip to the north-west. This dip ultimately brought to the surtace the Brighton Limestone, which, in a 175 short distance, was cut by a fault-plane on its northern side. This fault brought the Tapley’s Hill beds, by a down-cast, up against the limestone, so that the latter had the Tapley’s Hill beds both above and below it. The Tapley’s Hill beds, in the faulted area, showed. at the surface for about a milc, giving some evidence of crush, and were then succeeded once more by the Brighton Limestone, being the fourth exposure of this limestone in succession within the limits of about five miles. Following on the limestone the Purple Slates Series also once more came into view, and henceforth became the constant surface feature for an indefinite distance in a northward direction. Fig, 9.

The thickness of these beds. is not shown, but they greatly exceed the dimensions of the present creek’s deposits. They are seen in regular bedded masses in vertical faces up to 20 feet, and exhibit a continuous outcrop along the creek for more than a quarter of a mile. Higher up the stream they are seen to rest on the eroded edges of the Adelaide Series, and, easterly, they become obscured in the recent sandy clays of the plain. OvappigE TIints. The Oladdie Hills form an isolated group of highlands situated in a north- easterly direction from Walloway, at a distance of about twelve miles. Mr. Knight, of Walloway, kindly acted as my guide. The hills mentioned (lying to the east- ward of the strike of the Brighton Series, that have a westerly dip in the Walloway district) gave promise of containing some of the lower members of the Adelaide Series, which proved to be the case. Following the main north-east Johnburgh road, the Oladdie Creek, which forms the main artery of drainage for the group, was passed in Section 83, Hundred of Oladdie. Taking advantage of a branch road that led to the hills, and passing up a small creek that crossed the road, the base of the hills was reached in a quarter of a mile. Herc, thin-bedded calcareous and siliceous slates showed themselves with a dip to west-south-west at 25°. On reaching the second heights, about two-thirds from the top, the tillile was met with, and at the crest of the hill, hard siliceous slates and quartzites. No oppor- tunity occurred to make a more particularized examination of the ground. Mr. Knight stated that the tillite continues in a north-easterly direction, past the Oladdie Head Station, on the eastern side of the Prince Alfred Mine, and about four or five miles on the western side of the Baratta Head Station, covering a distance of 70 miles. 176 ACKNOWLEDGMENTS.

Finlayson, S.A. Museum. [Read September 11, 1930.] 1, Petaurus breviceps, the smallest of the Phalangeridae in which the flying membrane is sufficiently developed to permit of gliding flights of some duration, has a wide distribution throughout the eastern forest. tract of Australia, from Cape York to Tasmania,“ and as the variety papuanus occurs in New Guinea as well. In the stringy-bark forests of the Portland district of Western Victoria it is plentiful, and as large tracts of very similar country are to be found in the adjacent South-Eastern district of this State, its apparent absence from, or at any rate, great rarity in, South Australia, has long been a matter of note, On several occasions I have seen captive examples in the border towns of Frances, Naracoorte and Penola, but in each case these pets had been brought across from Victoria. It is said, by residents, to occur in the pine plantations between Penola and Mount Gambier, but whether this is so or not, Wood-Jones’ statement in 1924, that “there is no definite record of it having been taken in S.A.” has remained true till the present ‘(Mammals of S.A,, pt. ii., p. 194). It is satis- factory, therefore, to be able at last to report the taking of two individuals in South Australian territory, a clear 30 miles west of the Victorian border, The first specimen (an incomplete skin), for which I am indebted to Mr. James Clifford, of Furner, was obtained in July, 1929, at the Diamond Swamp, in the Hundred of Short; and the second, for which I have to thank Mr. Walter Foster, of Naracoorte, was got at Callendale, in the Hundred of Coles, about 10 miles north of the first locality. These places are about midway between the border at Comaum and the coast at Nora Crina Bay, and both constitute small oases of big timber and grassland on one of the broadest stretches of heath in the district—a heath which extends with practically no break from this point to Penola. The gentlemen named are both familiar with the fauna of the district, and as this is the first occasion that they have observed the animal, it appears certain that it is only just invading this country as a result of a slow westerly drift from some of its Victorian strongholds. The heath is not well suited to its habits, and this perhaps sufficiently accounts for its long confinement to the border district ; a few miles further east, however, it will reach a much richer type of country, where the dwarf stringy-barks are replaced by well-grown red and blue gums, and here it may be expected to increase rapidly if it receives any tolerance from the settlers. @) Tt was introduced into Tasmania in 1835, and the general belief that it had no place in the indigenous fauna of the island appears to rest ultimatcly on the statement of Gunn, that “no species of Petaurus is indigenous to Tasmania” (Proc. Royal Soc, Tasmania, vol. i, p. 253, and Tasmanian Journal, vol. il, p. 458). Whether the fauna of so tugged and inaccessible a country was sufficiently well known at the time to justify this sweeping statement, may be doubted, the more so as its distribution at Present appears to be as wide as any of the undoubtedly indigenous mammals. 178 2 In October, 1929, the S.A. Museum received a small collection of mammals made by Mr. R. Williams, in the Musgrave Ranges, near the south- western border of Central Australia. The chief interest of the collection centres ‘1a tabbit bandicoot which was obtained at Opparinna Spring, about 50 miles north-east of Mount Woodroffe. The specimen is an aged female with partly furred pouch young, and on examination proves to be referable to Thalacomys lagotis (Reid). In 1905, Oldfield Thomas (Ann. and Mag. Nat. Hist, (7), xvi., 1905, p. 426), on the evidence afforded by a specimen from Killalpaninna, on Cooper’s Creek, S.A., described a new species of Bilby, somewhat closely allied to Th. lagotis under the name Th. sagitta, and in so doing he appears to have been under the impression that the new species was the South Australian representative of Th. lagotis, the latter being confined to Western Australia. Wood-Jones, in his comprehensive paper on the genus, im 1923 (Records of the S.A. Museum, vol. il., No. 3, 1923), in correcting this, pointed out that the new species, Th, sagitla, was confined to the far northern districts of South Australia and to the centre, while lagotis, identical with the Western Australian animal, was the characteristic species of the “more watered and more fertile districts of the southern portion of South Australia.” As a consequence of these and other remarks derived from the latest work on the genus, it would seem 1o be implied, that (a) Th. lagotis is absent from the central districts, and (b) the earlier records of Peragale lagotis, by Baldwin Spencer and Sanger, apply to Th. sagitta (Thos.) rather than to Th. lagotis (Reid). The Opparinna specimen (S.A. Museum, number M2569) has the following approxmnate dimensions (taken from the filled skin). Ilead and body, 360 mm. ; tail, 200 mm.; ear, 75 mm.; pes, 90 mm. It is thus considerably smaller than the average adult female lagotis from Western Australia, and little larger than sagilta. From the latter, however, it 1s at once distinguished by several characters, both external and cranial. The pelage is almost exactly as in the western lagoits, the black portion of the tail is considerably longer than the white, and the lower surface of the pes is black throughout its posterior two-thirds. In the skull it resembles Jagotis, and differs from sagitta in that (a) the nasals reach to within 2 mm. of the interlachrymal line ; (b) the molar series has a rounded outline without the cven posterior divergence of sagitta; and (c) the molar teeth are very large. The large size of the molars is the most notable feature of the skull and identifies it very positively with /agotis since the teeth in this species, although they vary in size within rather wide limits, are always markedly larger than in any other form. The transverse diameter of M2 in the skull under consideration is 5°5 mm., as against 4-0 mm. for the corresponding tooth in the sagitta skull, measured by Wood-Jones (S.A. Museum, reg. number M.1622); an extraordinarily large difference in skulls which differ but little in basal length. It is to be regretted that Mr, Williams was unable to obtain an adequate series of this interesting Bilby, but as the characlers on which the identification @) Not to be confused with Opparinna Well, 75 miles south of this locality, in country traversed by the Elder Expedition. @) The palate has been damaged so that it is not passible to test-the site of the last molar, relative to its posterior margin—a feature, held by Wood-Jones to have specific value within the genus, but which in Jagotts, at least, appears to be rather variable and considerably influenced by age. 179 rests are quite pronounced, the récord of this single specimen may perhaps suffice to reinstate Th. lagotis in a somewhat dwarfed form, as a member of the Central fauna, 3. The rock wallaby obtained by the Horn Expedition in the MacDonnell Range was assigned by Baldwin Spencer to Petrogale lateralis Gould, with the remark that “all the specimens seen were of the typical colouration.” (Horn Expd. Report, “Mammals,” p. 15.) These specimens were obtained at Paisley’s Bluff, 37 miles west of Alice Springs and 1,200 odd miles from the type locality in the Swan River district of Western Australia. From a consideration of this immense distance, and in view of the subsequent separation by Oldfield Thomas of two insular races of Pt. lateralis, as full species under the names Pt, hacketti and Pt. pearsoni, it seems very likely that a critical examination of adequate series of rock wallabies from the centre and south-western Western Australia, would reveal much greater differences than have so far been described. The more so as Stirling and Zietz (Trans. Roy. Soc, S.A., vol. xvi. (1892-1896), p. 155) had already noted that the rock wallabies obtained by the Elder Expedition in the Barrow Range, 450 miles west-south-west of Alice Springs, were more conspicuously marked than those from the latter place, ~ The material available in Adelaide is inadequate for such a comparison, and the purpose of the present note is to record certain colour variations, either stub- specific or seasonal in character, which occur within a comparatively small area of the centre itself, and to draw attention to the ‘necd for a complete revision of the species, by those who possess material from the type locality, In August of last year, while acting as a member of the Adelaide University Anthropological Expedition to Hermannsberg, Mr. H. M, Hale obtained for the S.A. Museum a series of five skins and skulls of rock wallabies which had been brought in by the blacks from Koporilya Spring, 10 miles west-south-west from the Mission Station. These skins, while showing the characteristic markings of lateralis, are distinguished at once by the strikingly parti-coloured nature of the dorsal surface; the contrast between the light areas of the neck and shoulders on the one hand, and dark lumbar area on the other, being much enhanced from what usually obtains. When compared with skins taken at Alice Springs and Simpson’s Gap (80- 100 miles east), the following differences are noticeable. On the neck and shoulders the colour is a clear ashy grey, free from any fulvous suffusion, and markedly grizzled by the presence of a white sub-terminal band on the guard hairs. The fur is harsher and less silky in texture on these parts, and recalls somewhat the condition in the penicillata group. The colour of the lower back varies slightly in the different skins, but in the darkest (M.2683) it is a dull purplish-brown (near Ridgway’s Carob Brown). and in all is very different from the luminous fawny brown hues of the more easterly skins. The axillary patch, and the nuchal, loreal and lateral stripes are individually more strongly developed, but in a general view the skin appears sombre, ‘The tail is darker throughout its length, and for its distal half is quite black above and below—much as in hacketti but with shorter brush hairs. ‘The carpus and metacarpus are yellowish-brown and strongly contrasted with the much darker digits; in the Alice Springs material the whole of the manus is a dull uniform brown with little differentiation of the digits. On the other hand, the pes in the Koporilya specimens is darker and the terminal ungual tuft not con- spicuously contrasted with the toe. The skulls are those of males, and the four which are undamaged are from very old individuals in which the fourth molar has undergone considerable wear 180 and is 5 mm. or more in advance of the posterior margin of the palate. For comparison with this material, a series of seven skulls in a similar dental stage has been available, derived from Alice Springs and Simpson’s Gap, and the mean value of the chief cranial measurements is appended. The Alice Springs skulls, | unfortunately, are incompletely sexed, and most of the discrepancies which this comparison brings to light are probably assignable to this cause. Although the Koporilya skulls are uniformly large and heavy, a detailed comparison, point for point, fails to give any indication of structural differences of importance, and the largest males of each series are in very close agreement (see table). There is, thus, no question of more than subspecific differences involved, and since the more westerly skins were taken in August and the easterly in October, it is possible that the differences in pelage noted may represent the extremes due to a seasonal change. Oldfield Thomas refers in several papers to the “bleached” or “faded” condition of certain rock wallaby skins, but no change so marked as that which is dealt with herein appears to have been previously described.

CORRESPONDENCE— A letter of acknowledgment from the President (Dr. L. Keith Ward), thanking Fellows for having re-elected him as President for a further term, was read, A letter from the Secretary, Department of Home Affairs, Commonwealth of Australia, stating that free transport to the value of £25 was granted over the Commonwealth railways for foodstuffs, for the aborigines of the Hermanns- berg district, was read. Motions— Mr. Roach moved, and Mr. Bailey seconded: “That the name of the Acting Honorary Secretary, Mr. Ralph W. Segnit, be forwarded to the Savings Bank of S.A. for the purpose of operating on the Society’s Account.” Carried. Mr. Kimber moved: “That this Society records its great appreciation of the action of the Board of Governors in purchasing the splendid collection of shells of the late W. L. May, of Tasmania.” Mr. Kimber said that we are aware that this State is very fortunate in having such a generous citizen as Sir Joseph Verco, who assisted so liberally in defraying the cost of the May collection. Our obligations to Sir Joseph have been added to recently, as he has purchased and presented to the Museum the very fine collection of the late Messrs. W. T. Bednall and E. H. Matthews. These collections, in addition to that invaluable one of Sir Joseph’s, are now in the National Museum, and make our conchological collec- tion a very valuable one. The CHAIRMAN extended an invitation to the Fellows of the Society, on behalf of the President of the Royal Geographical Society of Australia (S.A. Branch), to be present at a lecture to be delivered by Mr. C. T. Madigan, ort December 2, in connection with his recent Air Survey Expedition over part of Central Australia. ELecrion oF FrELLow.—Worsley C. Johnston, Government Agricultural Inspector, Riverton. A ballot was taken and Mr. Johnston was declared elected. NoMINATION as FELLow.—Rev. Napoleon IIenry Louwyck, Minister of Religion, The Rectory, Yankalilla, was received. Parer.—‘‘Notes on Australian Polyplacophora, No. 1, by Epwin AsHpy, F.L.S., M.B.O.U., and Bernarp C. Corron. Exurpirs—Mr, Ratpo W. Sgenitr exhibited an Ivory Gull, Pagophila eburnea, which he collected in Ice Fiord, Spitzbergen, during the Oxford Uni- versity Expedition to Spitzbergen in 1921. Mr, ARTHUR M. Lea exhibited two 182 drawers of very interesting insects recently obtained from Papua. They included sume of the largest and most remarkable species from that httle-known country. The Rev. |. C. Jennison exhibited some artifacts from an aboriginal camp site near Baldina Creek, Burra district, 5.A. He said that the collection, numbering 50 specimens, included chipped-back knives, so-called “spear heads,” scrapers and drills. The whole region, apparently for miles along both banks of Baldina Creek, above and below the spring at the Broken Hill road crossing, though stony ground, had been used as camp sites, The enormous quantities of stone implements scattered everywhere is evidence of the use of this place as a camp area for a very long period. Mr, A. E. Epguist exhibited a seedling mallee, three years of age. ‘The specimen showed the development of the swollen stem, commonly known as “mallee root? The mallee root is really a swollen portion of the stem from which branches grow in a ring. The specimen was grown from seed collected from Kangaroo Island. Mr. A. A. Simpson then moved that this Society communicate with the Minister of Railways, requesting that a list of the protected fauna be placed in all railway stations in South Australia for the information of the public. The motion was seconded by Dr. Morgan, and carried unanimously, The CHAIRMAN announced that a satisfactory agreement had been reached with reference to the use of part of the central room, between this Society and the Royal Geographical Society of Australia (S.A. Branch). Dr. T. D. Campseti put forward a suggestion that one or two meetings in the year be devoted to special subjects, with a view to encouraging. discussions. Dr. T. D. Campbell then moved, and Mr. Arthur M. Lea seconded, that this matter be placed before the Council. Carried. Orprnary Meerinc, Aprit 10, 1930. ‘Tire Presipent (Dr. L. Keith Ward) occupied the chair, and 41 Members were present, Minutes of the Ordinary Meeting, held on November 14, 1929, were read and confirmed. Tin Presipent referred to the irreparable loss caused by the death of Pro- fessor T. Brailsford Robertson, He said Professor Robertson was a most dis- tinguished investigator, his genius being directed towards the solving of some of the most important national problems. His decease left Australia much the poorer. Tne Presipent then referred to the successful return of the “Discovery” from the Antaretic, and on behalf of the Society congratulated Sir Douglas Mawson, a former President, and Professor T. Harvey Johnston, Vice-President of the Society, on their stccessful trip. ‘hey would await with interest the scientific results of the expedition, confident that they would fully justify the arduous work which had been undertaken. The attention of the Fellows was then directed to the Rules governing the pre- sentation of papers to the Society for reading. The President laid special stress on the “Suggestions to Authors,” and the time of lodging the papers for con- sideration by the Council. Tip RESIGNATION OF THE SECRETARY (Dr. R. H. Pulleine) was placed before the Fellows and accepted. Nominations were then called to fill the vacancy. Mr. B. 5. Roach nominated, and Dr. R. H. Pulleine seconded, the name of Mr. Ralph W. Segmit. There being no other nomination, the President declared Mr. Segnit elected. Tare SECRETARY read a notice received from the Secretary of the A.AVA.S., requesting that delegates be appointed for the meeting to be held in Brisbane from 183 May 28 to June 4, 1930. Dr, Charles Fenner moved, and Dr. R. H. Pulleine seconded, that Mr. Ernest H. Ising and Mr. C. S. Piper, M.Sc., be elected dele- gates. Carried. ‘HE PRESIDENT referred to correspondence received from the Secretary of the Royal Society of Victoria, relating to a conference to be held at the Brisbane meeting ot the A.A.A.S., to discuss the advisability of the federation of the Royal Societies of Australia, and asking for two delegates to be appointed. It was agreed that two delegates be appointed, and that they report the result of the conference to the Society at a later date. Dr. R. H. Pulleine moved, and Mr. B. S. Roach seconded, that the President (Dr. L. Keith Ward) and Dr. Charles Fenner be elected delegates. Carried. THe Presipenr said that the suggestion brought forward by Dr. ‘Tb. D. Campbell to hold one or two meetings a year for the purpose of discussion on selected subjects, had been referred to the Council, who recommended the sugges- tion to the Members and had set aside the May Ordinary Meeting for the purpose. Dr. T. D. Campbell then gave a brief outline of his idea. The subject would be “The Antiquity and the Primitiveness of Man in Australia,” and would be taken up in the form of four short lecturettes.

Minutes of the Ordinary Meeting, held June 12, 1930, were read and confirmed. Sir JosepyH Verco Mepavyist.—The President then addressed the Members as follows :— “The most pleasing of the duties which must be performed by the Council of this Society is the selection of one of its Fellows for the award of the Sir Joseph Verco Medal for distinguished scientific work. The time has come for the submission to the Society of the name of the second recipient. “The choice of the Council has been unanimous, and has fallen on one of its senior Fellows who is not at present in South Australia, but who is representing this Society at an important conference in Great Britain. I refer to Mr. John McConnell Black, who is a Fellow of many years’ standing, and at the present time a member of the Council. “In submitting his name to the Society for its verdict, your Council would have me express its deep appreciation of the service to science, and to the State, by Mr. Black, whose wise counsel has been available at all times to the Society in its corporate capacity, and to the many individual Fellows who have had occasion to consult him. “Mr. Black is a man of many parts. Educated in Scotland, England, and Dresden, he came to Australia in 1877 and engaged in farming in the Baroota district for the next five years. For the following 20 years he was on the literary staff of the Adelaide Press, and, after withdrawing from this work, concentrated his energy mainly upon the study of the systematic botany of South Australia. But he has not neglected the claims of literature to which his early training and more mature study have held him captive. An accomplished linguist, he is an authority on the structure of languages generally. “Mr. Black’s contributions to the Society have been distinguished for the modesty with which they have been presented as for their crisp clarity. His labours have been such that they have been completed but for a strong sense: of devotion to science and fine ideals. To him the achievement of his aims has certainly been a great reward. But your Council asks you to record the appre- ciation of the value of this work to science by the award of the highest honour at your disposal. “At the moment Mr. Black is representing this Society at a conference con- vened in Cambridge to deal with botanical nomenclature, and we are fortunate in having so distinguished a representative. “At the desire of the Council, I am asking the Director of the Botanical Gardens (Mr. J. F. Bailey) to address you with regard to Mr. Black’s contribu- tions to botany, and I am asking a former President of this Society, who is him- self a foremost authority on the orchids of Australia, Dr, R. S. Rogers, to support the proposal.” Mr. J. F. Bailey said :— “Mr. President.—It affords me much pleasure to propose to the Members that the decision of the Council in recommending that the Sir Joseph Verco Medal be awarded to John McConnell Black be adopted. “Mr. Black has always taken a kecn interest in botanic nomenclature, and is at present in England with the object of attending the International Botanic Nomenclature Congress to be held in Cambridge next month, as the Australian representative on the Committee. G 186 “Tt is scarcely necessary for me to remind the Members of the great amount of work carried out by Mr. Black in making known the flora of this State, for in this connection his name has been prominently before the Society for many years. “In recognition of his services in the cause of botany, the Council of the Adelaide University appointed Mr. Black as Honorary Lecturer in Botany at that institution. “Tn 1909 Mr. Black published an illustrated work on “The Naturalized Flora of South Australia,” and this has been of great value to the man on the land, as it deals with many of the weeds with which he has to contend. “Mr. Black has visited many parts of this State at his own expense in pursuit of material for his favourite study, and the results of his investigations have, from time to time, been embodied in papers presented to this Society and pub- lished in its Proceedings. During some of these journeys Mr. Black, who is an expert linguist, acquired a knowledge of native languages in certain districts which enabled him to compile the vocabularies to be found in the Proceedings of this Society. By this means he obtained much useful information regarding the uses to which certain plants were applied by the aborigines. ‘When the South Australian Branch of the British Science Guild arranged for the publication of handbooks on scientific subjects relating to South Australia, it was only natural that Mr. Black’s aid should be sought to prepare the one on the flora.” This huge task he willingly agreed to undertake, and last year the fourth and last part was issued, In this publication the author has not only described many new species, but has compared, and in many cases augmented, the descriptions of those already brought under notice by other botanists, and these factors have combined in giving to the botanic world a publication that is proclaimed as the standard work on the State’s flora. While referring to this work, it is but fair to add that the section devoted to Orchidaceae was entrusted to, and ably treated by our friend Dr. R. 5S, Rogers, one of our former Presidents, and who is the recognised Australian authority on this family of plants. “Not only do we respect and esteem Mr, Black for his work in the realm of botany, but also for his willingness at all times to give freely from his vast store of knowledge to those seeking his advice on the subject. Our friend also possesses the charm of endearing himself to those with whom he comes in contact. “Tt is, therefore, fitting that the Members recognise Mr. Black’s merit by awarding him this coveted medal, and I have pleasure in again proposing that this course be adopted.” Dr. R. S. Rogers, in seconding the motion, said :— “The people of South Australia are deeply indebted to Mr, Black for the elucidation of their flora, a purpose to which he has devoted nearly thirty years of his life. “At first his scientific researches were chiefly directed to the alien plants of this country, and his “Naturalised Flora of South Australia” (1909), the first of its kind available in the Commonwealth, is an excellently conceived and well executed handbook of great economic importance. “Since his election as a Fellow of this Society (1907), he has contributed 28 botanical papers, and has added to our census upwards of 100 new plants. ‘During the seven years, 1922-1929, he devoted practically the whole of his time and energies to a critical review of the indigenous flora of this State, and as a result of his researches, has presented us with an exhaustive handbook of the “Flora of South Australia”; modern in its treatment and generously illustrated with his own drawings. This work, which contains many original features, has 187 evoked the praise of critics throughout the botanical world. I venture to predict that it will be the standard work of reference for at least the next 50 years.” The motion was supported by Professor T, Harvey Johnston, and then put to the meeting, and the President declared that the motion was unanimously carried, The President then read a letter received from Sir Joseph Verco in connec- tion with the making of this award. Exrection.—A ballot was taken and the following were declared duly elected as Fellows :—Frank Vernon Collins, B.V.Sc.; Thomas Talbot Colquhoun, M.Sc. ; Frederick John Hall; Garth Palmer Ockenden. Nomrnations.—The following nominations for Fellows were read :—Lewis George Morris, Optometrist, Beehive Building, King William Street, Adelaide; Albert James Whitelaw, School Teacher, c/o Norwood High School, Kensington; Edward Victor Dix, Civil Servant, Glynde Road, Firle; Walter Richard Birks, B.Sc., Principal, Roseworthy Agricultural College; Stephen Denis Garrett, B.A., Plant Pathologist, Waite Agricultural Research Institute, Glen Osmond; Pro- fessor Herbert John Wilkinson, B.A., M.D., Ch.M., University, Adelaide. LECTURETTES.—“Fossil Man in the Murray Valley?” Five lecturettes on some researches and excavations at Tartunga and Devon Downs, illustrated with lantern slides and exhibits, were presented by :— Mr. H. M. Hare, who gave a “Resumé of the Investigations.” Mr. N. B. Trnpae dealt with the “Human Remains and Associated Arti- facts,” and on behalf of Dr. T. D. Campbell, some “Dental Notes.” Dr. CHARLES FENNER described the ‘‘Physiographic Aspect.” Mr. H. H. Fintayson described the “Mammal Remains.” In the discussion which followed, Proressor W. Howcuin made reference to the thorough manner in which the investigations had been carried out, and said that it stands as one of the finest efforts put forward in Australia in connec- tion with this subject. Ie agreed that antiquity can be claimed for the results presented, and suggested that in lieu of the term “distinct cultures,” as used by Mr. Hale and Mr. Tindale, the term “different series of occupation’ be substituted. Dr. R. PULLEINE referred to the remark made by Mr. Finlayson, tha iome doubt existed as to whether the early aborigines had used the so-called Tas: sanian Devil (Sarcophilus) as food, and referred to the collection of materials he had brought back from Tasmania, in which were bones of the mammal, some burnt and charred, and included evidence that the early Tasmanians had probably used this animal as food. THE PRESENT congratulated the investigators on their very interesting and important work, and said that the geologist had great difficulty in determining the exact “time factor” in connection with the geological deposits. The results were an example of good co-ordination and teamwork in scientific investigations, and equalled any similar work carried out in Europe. Dr. Ward expressed the sincere thanks of the Society to the Lecturers for offering such a splendid contribution towards the evening’s meeting. Orptnary Mretine, Avoust 14, 1930. Tue Presipent (Dr. L. Keith Ward) occupied the chair, and 20 Members were present, Minutes of the Ordinary Meeting, held on July 10, 1930, were read and confirmed. 188 Tuer PresipentT informed the Members that he had sent a cable to Mr. J. M. Black, notifying him that he had been awarded the Sir Joseph Verco Medal by this Society, and having received a cable reply thanking the Fellows for the honour conferred. Tur Presipenr then expressed the appreciation of the Members of this Society of the honour conferred on Mr. J. M. Black on his having been elected an Associate of the Linnean Society of London. BaLtot as FeLLows.—A ballot was taken, and the following were declared duly elected by the President -—Professor Herbert John Wilkinson, B.A., M.D., Ch.M.; Lewis George Morris; Albert James Whitelaw; Edward Victor Dix; Walter Richard Birks, B.Sc.; Stephen Denis Garrett, B.A. Nominations as Fetrows.—The following nominations were read :—Jack Sargent Hosking, B.Sc., Assistant Chemist, Waite Agricultural Research Insti- tute, 90 Cross Roads, Myrtle Bank; Anne Irene McFadyen, B.Sc., Teacher, Wal- ford House School, Unley. Parer—“On Some Coleoptera from Northern Australia. Collected by Dr. H. Basedow,” by ArrHur M. Lea, F.E.S. Exuipits—Mr,. Artuur M, Lea exhibited a drawer of Orthoptera from New Guinea, including some Katydids with remarkable leaf-life wings and some walking-stick insects nearly one foot in length. Professor T. Harvey JOHNSTON exhibited two whale-darts, and a whaling-bomb, and gave an interesting account of their uses in connection with the whaling industry in the Antarctic waters. Dr. CHartrs FENNER exhibited a series of volcanic bombs from Buninyong, Victoria, and two somewhat exceptional examples of glaciated rocks of the Pleistocene from Western Tasmania. The President said that it was possible to obtain from some places boulders having two sets of glaciated markings, one set being from a later period of glaciation than the first, and in answer to Mr. Lea gave a brief account of the latest researches in connection with the obsidian bombs found in Central Australia. Dr. T. D. CAMPBELL exhibited a series of deciduous teeth taken from the native rock shelter floor excavated by Messrs. Hale and Tindale. Along with these were the corresponding deciduous tecth of an orang- outang, and of modern white children. The Australian infants’ teeth showed extraordinary pithecoid characteristics with regard to size and form. Tut Presipent exhibited the following :— Stichtite, a chromiferous magnesium hydroxycarbonate, occurring as irregularly shaped masses, veins and blebs in serpentine at Dundas, Tasmania, in the neighbourhood of the Adelaide mine. Weathered surlaces are dark brown, but the fresh mineral ranges in colour from lilac to deep purple. The mineral is built up of radiating tufts and plates about crystals of chromite. It is allied to hydrotalcite, pyroaurite and brugnatellite. “he name was given in complimen- tary reference to the late S. Sticht, General Manager of the Mount Lyell mine. Rodingite, a rare rock from the Dun Mountain, near Nelson, in New Zealand, occurring in the form of dykes which penetrate the dunite which is an ultrabasic igneous rock composed almost wholly of granular olivine. Rodingite consists essentially of greenish-white grossularite (lime-alumina garnct) and diallage; and the grossularite is in many places altered to prehnite. Bell, Clarke and Marshall, who determined the rock, regard it as a differentiation product of the peridotite; rather than as the result of the assimilation of limestone by the magnesian magma. Dunite, from the Dun Mountain, Nelson, New Zealand, consisting essen- tially of olivine, with which a little chromite is associated, Ribbon-stone, a variety of banded flint, composed largely of granular chalcedony together with some opal. Found on the surface of the Cambrian 189 limestone of North Australia, whence it has been set free by weathering. Some specimens exhibit a very deep patina, others are polished by drifting sand and show the typical desert varnish. sokerite, natural wax from a depth of 6,000 feet in the Springleigh bore, Queensland, which has a total depth of 7,008 feet. Petrol, condensed from natural gas at a depth of 3-7,000 feet at Roma, Queensland. Crude Petroleum, from Taranaki, New Zealand. Stellite is an alloy composed essentially of cobalt, chromium and tungsten, which was discovered as a direct result of research carried out with the object of finding a use for the cobalt of Ontario. On the development of the rock silver ores found in 1903 at Cobalt, 330 miles north of Toronto, stocks of the metal cobalt accumulated and could not be disposed of for the manufacture of pigments and special steels. Systematic investigations resulted in the production of this alloy, which is used to a small extent in the preparation of rustless cutting tools, but extensively to replace high-speed tool stecls. Stellite will retain its hardness almost to bright red heat—a temperature far above that at which steel softens. On cooling, the heated stellite retains its hardness. It cannot be annealed and cannot be machined except by grinding. Stellite, on account of its extraordinary resistance to abrasion, is used today on the teeth of calyx boring bits. The stellite is applied by the process of welding with the oxy-acetylene flame, which causes the fusion of the alloy and the steel at, approximately, the same temperature (2,336° F). A boring bit, the teeth of which are armed with stellite, was exhibited, as well as a rod of the alloy itself. Bits armed in this manner are in use by the Department of Mines of South Australia. ORDINARY MEETING, SEPTEMBER 11, 1930. Tue Presipent (Dr. L. Keith Ward) occupied the chair, and 30 Members were present. Minutes of the Ordinary Meeting, held August 14, were read and confirmed. Evectrions.—Jack Sargent Hosking, B.Sc., and Anne Irene McFadyen, B.Sc., as Fellows. A ballot having been taken, the President declared them duly elected. Nomination,—James Tinsley Gray, Pharmacist, Orroroo, as Fellow. PAPERS— “The Geology of Orroroo and Surrounding District,’ by Professor Watter Howcun, F.G.S. “Notes on Some South and Central Australian Mammals,” by H. H. FINLAYSON, “Descriptions of Australian Resupinate Hydnaceae,” by E. M. WAKEFIELD, Communicated by Professor J. B. Cleland, M.D. Exuisits—Mr. Artuur M. Lea exhibited a drawer of weevils from New Guinea of the sub-family Brachyderinae, many of which were brilliantly coloured. Mr. C, T. Mapican exhibited specimens of fossilized vegetables, which were pre- sented to him by Mr. O’Grady, Arltunga, and said they were obtained from a place about 74 miles E.S.E. from the Battery of Arltunga Goldfields. The President said the specimens were of a fossilized fern, which he thought came from Paddy’s Plain, between Bitter Springs Gorge and Arltunga Goldfields. Professor Walter Howchin suggested that one of the specimens was Osmundites, related to the existing “Royal Fern” (Osmunda), of which better specimens had been obtained from the interior, probably from the “Desert Sandstone.” 190 ANNUAL MEETING, OcroBEer 9, 1930. Tue PresipeNt (Dr. L. Keith Ward) occupied the chair, and 24 Members were present. Dr. D. S. Davipson, of Pennsylvania University, who is studying the Aus- tralian Aborigines in Northern Australia, was welcomed as a visitor by the President. Apologies were received from Professor J. A. Prescott and Mr. H. M. Hale, Minutes of the Ordinary Meeting, held September 11, 1930, were read and confirmed. Tire SECRETARY presented the Annual Report for the year 1929-1930. The adoption was moved by Dr. T. D. Campbell, and seconded by Rev. J. C. Jennison, and carried. Tre Treasurer (Mr. B. S. Roach) presented the BaLance-sHEET. The adoption was moved by Dr. Chas. Fenner, seconded by Mr. Bailey, and carried. The President expressed the thanks of the Society to Mr. Roach for the valuable services he had rendered to the Society as the Hon. Treasurer, ELECTION oF OFFICERS FOR THE YEAR 1930-31.—Nominations were called and the following clected :—President, Dr. Charles Fenner ; Vice-Presidents, Pro- fessor ‘I. Ilarvey Johnston, M.A., D.Sc., and Professor J. A. Prescott, M.Sc., A.LC.; Secretary, Mr. Ralph W. Segnit, M.A., B.Sc.; Treasurer, Mr. B. S. Roach; Editer, Professor Walter Howchin, F.G.5.; Members of Council, Mr. A. M. Lea, F-E.S., Mr. J. F. Bailey, Mr. C. T. Madigan, M.A., B.Sc.; Auditors, Mr. W. C. Hackett and Mr. O. Glastonbury. Mr. James ‘linsley Gray, Pharmacist, Orroroo, was elected a Fellow of the Society. Mr. James Irvine Miller, C-E., Crystal Brook, 5.A., was nominated as a Fellow. Yur Presipent, on behalf of the Society, expressed the hope that Sir Douglas Mawson and Professor T. Harvey Johnston would enjoy health and success in connection with the second cruise of the Australian and New Zealand Antarctic Expedition. Dr. R. Lockwart Jack received the congratulations of the Society on hav- ing had the D.Sc. degree conferred on him by the University of Adelaide. A letter received from Mr. J. M. Brack was read, expressing appreciation for the honour conferred on him by this Society in awarding him the Sir Joseph Verco Medal for 1930. ; Exnrnits.—Professor Wa trer Howcnurn exhibited the vertebra of an Ichthyosaurian from the so-called “coprolite bed” near Cambridge, England. The - vertebra can be distinguished, partly, by its large size, the Ichthyosaurus being the largest of all the sea-going reptiles during the Mesozoic Era; also on account of its narrowness and biconcave shape. It was a very powerful swimmer, with a voracious habit. They existed in Australasian seas, as their remains are found in the Trias of New Zealand and the Cretaceous of Australia, One nearly com- plete skelcton, found at Marathon, Queensland, measures 25 [t. in length. Pro- fessor Howchin also showed an ichthyosaurian coprolite. It has become a habit to call all phosphatic nodules “coprolites,” many of which are of concretionary origin, but the specimen exhibited is a true coprolite, showing the twist of the gut and the polished enamelled scales of the ganoid fishes on which the reptile had dined, embedded in the faecal matter. Dr. T. D. Camesrett exhibited some pebbles and shell fragments collected on the sandy beach of Franklin Island. They presented a highly polished surface, as if they were varnished. Other unpolished stones from the same locality were shown. The President suggested that the polish was a “phosphatic film” covering the pebbles. Mr, ArrHur M. LEA exhibited two drawers of beetles of the family ‘“Tenebrionidae,” mostly from 191 New Guinea and Fiji, many of which were closely allied, if not identical, with Queensland species. Also two species of remarkable gall insects of the genus Apiomorpha, one of which constitutes an important article of aboriginal food; and a striking mantis /dolum diabolicum from the Anglo-Egyptian Soudan, sent by the Rev, D. N. McDiarmid and presented by Sir Joseph C. Verco. Mr. N. B. ‘TINDALE exhibited some native foods from MacDonald Downs, Central Australia. Two species of grass seeds accumulated by a small species of ant are gathered by the Hiaura natives, winnowed, ground, and cooked as a rough cake in the ashes. Also the honey of a native bee (frigonia) much relished by the natives. Mr, Tindale also showed a photograph of a native relief map, voluntarily made by an Iliaura native to demonstrate the positions of various waterholes and hills in his country; and a series of photographs showing a native preparing the seed- cake. Mr, C. T. Mapican exhibited a fossilized log of wood from the Water- house Ranges, south of Alice Springs, and the largest stone axe in Australia, measuring 10 inches by 84 inches, from Birdsville; and the smallest stone axe from an australite made by a native child. ANNUAL REPORT FOR THE YEAR ENDED SEPTEMBER 30, 1930. The average attendance of Fellows at the meetings held during the year has been 39, The President, Dr. L. Keith Ward, received the congratulations of the Society on his having been awarded the W. B. Clarke Medal by the Royal Society of New South Wales. Sir Douglas Mawson and Professor T. Harvey Johnston were welcomed and congratulated by the Society on their safe return from the first cruise of the Antarctic Expedition, Professor J. R. Wilton received the congratulations of the Society on his having had the Sc.D. degree conferred on him by the University of Cam- bridge. : During the year Dr. Robert Pullcine tendered his resignation as the Honorary Secretary of the Society, and Mr. Ralph W. Segnit was elected to the vacancy. Mr. J. M. Black, a member of the Council, was granted leave of absence to enable him to visit England and the Continent. During his absence the Fellows of the Society awarded him the Sir Joseph Verco Medal for 1930. Sir Douglas Mawson received the congratulations of the Society on being the recipient of the Mueller Medal from the Australian and New Zealand Association for the Advancement of Science. ; Mr. J. M. Black has been elected an Associate of the Linnean Society of London. The Board of Anthropological Research, Adelaide University, sent another expedition to the Interior. The following Fellows of the Society accompanied the expedition :—Professor T. Harvey Johnston, Ir. R. Pulleine, Professor J, B. Cleland, Dr. T. D. Campbell, Mr. Herbert M. Hale, Mr. N. B. Tindale, Dr. H. K. Fry, and Professor H. J. Wilkinson. Mr, Frederick Chapman, an Honorary Fellow, received the congratula- tions of the Society on being the recipient of the Lyell Medal from the Geological Society of London. A re-arrangement in the layout of the Society room and improvements to the lighting were effected during the year, and a new set of book shelves purchased for the library. The use of half the Central Room in conjunction with the Royal Geographical Society of Australasia (S.A. Branch) is much appreciated. 192 During the year two'of the Ordinary Meetings were devoted to special subjects, in the form of Anthropological lectures, which were largely attended. The first was a composite lecture dealing with “The Primitiveness and Antiquity of Man in Australia.” The following Fellows read short papers :—- Dr. L. Keith Ward, Dr. Charles Fenner, Dr. T. D. Campbell, and Mr. N. B. Tindale. Vhe second subject was entitled “Fossil Man in the Murray Valley,” at which the following Fellows contributed short lectures:—-Mr. Herbert, M. Hale, Mr. N. B. Tindale, Dr. Charles Fenner, Dr. T. D. Campbell, and Mr. H. H. Finlayson. Geological papers were contributed by Dr. Charles Fenner and Professor Walter Howchin. Zoological papers were read by Edwin Ashby, H. H. Finlayson, and Arthur M. Lea. Botanical papers were presented by J. M. Black, Dr. R. S. Rogers, Pro- fessor J. B. Cleland, J. G. Wood, and Miss E, M. Wakefield, her paper being communicated by Professor J. B. Cleland. Anthropological papers were read by Dr. H. K. Fry, Dr. Robert Pulleine. and Professor H. H. Woollard. The membership of the Society shows a slight increase. Fellows elected during the year, 15; 6 Fellows resigned, 4 died, and 1 was removed. “The membership roll at the close of the year is as follows:—Honorary Members, 5; Fellows, 161; Associate, 1. ‘lotal 167. During the year the Socicty has suffered loss by death of four Fellows, namely, Professor T. Brailsford Robertson, Mr. Francis H. Snow, Mr. W. A. Magarey, and Mr. A. S. Hirst. An Obituary Notice of Professor Brailsford Robertson, written by Pro- fessor Kerr Grant, appears at the close of this Report. The Council has met on nine occasions, the attendance being as follows: Dr. L. Keith Ward, 4; Professor T. Harvey Johnston, 5; Dr. Charles Fenner, 9: Mr. B. S. Roach, 9; Professor Walter Howchin, 9; Mr. Ralph W. Segnit, 8; Mr. J. M. Black, 2; Professor J. H. Prescott, 5; Mr. J. ¥. Bailey, 7; Mr. Arthur M. Lea, 7; Sir Joseph C. Verco, 0; Dr. T. D. Campbell, 8. The absence of the President from four meetings was due to his appoint- ment as a member of the Coal Commission, which necessitated his absence from the State. In April Mr. J. M. Black was granted leave of absence to visit England and the Continent; Dr. T. D. Campbell was in the interior of Australia during the August meeting; Professor T. Ilarvey Johnston was away from three meetings due to his absence from the State in connection with the Antarctic Expedition, and was in the interior of Australia during the August meeting; Mr. Ralph W. Segnit was on official duty in the North during the July meeting; and Sir Joseph C. Verco was prevented from attending for health reasons. T.. Kerra Warp, President. Raten W. Seanit, Secrelary. OBITUARY NOTICE. T. BRAILSFORD ROBERTSON, D.Sc., Ph.D. Thorburn Brailsford Robertson died on January 18 of this year. His death was a sacrifice to the spirit of devotion to his duty, which animated his whole life. Confined to his home at Mount Lofty by an attack of influenza, he insisted—despite all the urging which affection and solicitude could bring to dissuade—in motoring to Adelaide to give his personal attention to the pro- 193 gtess of an extraction which he had put in train prior to his illness. The temperature on that day was 106° in the shade. Pneumonia supervened, and later asthma—an enemy of his boyhood’s days. Every effort was made to save him, even to the extent of flooding the whole of the sick-room with oxygen, but all to no avail. The only portion of Robertson’s life story with which the writer has direct acquaintance is that during which he held the Chair of Physiology and Biochemistry at the Adelaide University, For the remainder, he owes his information to numerous press notices and to conversations held with his old friends and associates, Brailsford Robertson was born in Edinburgh in 1884, but came with his parents to South Australia at the age of ten. His early education was received from private tuition and at Miss Stanton’s private school at Glenelg. Inci- dentally, he was severely critical of modern methods of education, and was fond of quoting a saying: “By education genius is turned into mediocrity.” He entered upon the Science course at Adelaide University in 1902. I have been told and can well believe that, not having the necessary qualification for matriculation at that date, viz., a pass in either Latin or Greek, he began upon the study of the latter language three weeks before the date of the examination, in which he triumphantly acquitted himself. This may, perhaps, in part explain the contempt which he often expressed—not indeed for a knowledge of foreign languages—ancient or modern—but for that deplorable ineptitude in their use which rewards the schoolboy’s strenuous struggle of several years with their grammatical forms and syntatical irregularities, Robertson’s objective from the outset appears to have been the study of biological science. But he told me once that early in his student days he came to the conviction that little progress in any attack on the fundamental problems of the phenomena of life could be successful unless founded upon the conceptions and laws of the basic sciences: mathematics, physics, and chemistry. This conviction it was which, after graduating at Adelaide with first-class honours in physiology, took him to the University of California, there to sit at the feet of the great physiologist and biochemist, Jacques Loeb, whose recent success in artificially fertilising the ova of sea-urchins had attracted world-wide attention. Robertson’s ability was evidently not lost upon his teachers at Berkeley, for immediately after graduating as Ph.D, in 1907 he was appointed an assist- ant professor of chemistry, and later in the Same year to the same rank in the department of physiology. While teaching at California he carried out experimental researches on the functions and biochemistry of the pituitary gland. This work resulted in the discovery of a substance, extractable from the gland, which had a remarkably powerful stimulating action on the growth of tissues. Robertson gave this extract the name of “Tethelin.” In 1910 Robertson paid a short visit to South Australia and married then Miss Jane Winifred Stirling, third daughter of Sir Edward Stirling, Tn 1918 he accepted the offer of the Chair of Biochemistry at the Univer- sity of Toronto, and in the following year, on the demise of his old chief, he was invited by the Council of Adelaide University to succeed him in the Chair of Physiology. The contrast between the ample facilities made for the teaching of the biological sciences in American Universities and the meagre- ness of the provision made for the same end at Adelaide must, I think, have impressed Robertson very acutely, and he lost no time in urging upon the Council the necessity for a new laboratory and a re-organisation and increase of the teaching staff. He had his own peculiar and effective way of getting what he wanted. Within a year he had secured from the University Council 194 a promise to erect a new building for physiology and biochemistry, and towards the expense of its erection a very handsome monetary contribution from the heirs of the late John Darling. The “Darling Building” for the mnedical sciences was completed in 1922. Robertson’s genius for detail—with- out the closest attention to which, as Napoleon once said, no project can sticceed—is to be seen in a hundred features of the internal design and fittings of this fine laboratory. Here he began his long series of experiments on the influence of various supplementary food factors on the growth of mice, breed- ing for that purpose a special strain of white mice. Mainly by Robertson’s personal efforts a sum of no less than £7,000 was raised by private subscription from public-spirited citizens of South Australia to provide the necessary financial support for this experimental work. This sum now constitutes the Animal Products Research Foundation of the University of Adelaide. One very tangible return for this benefaction was made when immediately after the discovery of the “Insulin” treatment for diabetes thousands of doscs of this extract were prepared for the use of sufferers in South Australia. He carried on concurrently with this work and, of course, with his teach- ing duties likewise, various other experimental investigations, mainly on the problems of growth of unicellular organisms. I am not competent to comment critically on the value or importance of the results obtained from the point of view of a biologist, but speaking as a physicist 1 would say that the dis- covery of the identity—or at least close similarity—of the law of growth both for unicellular and for polycellular organisms with the law of progress of an autocatalytic chemical re-action must be a fact of fundamental significance in biology. Yet Robertson was aiming, as he disclosed to me in our not infre- quent discussions about his work, at a much deeper probing into the nature of vital processes. He realised that neither dictetic nor ordinary environmental influences do, as a rule, penetrate the very citadel of life—the nucleus of the cell__and I recollect a long discussion, prior to my visit to England in 1927, on the question of the possibility and of the technique of making an attack on this impregnable citadel by the agency of the radiations from radium or other radio-active substances. How sound his intuition was in selecting such 4 line of attack has since been demonstrated by the discovery by American geneticists, that the number of mutations in the offspring of a species of fruit-fly (for example) can be enormously increased by irradiation of the eggs with X-rays of gamma-rays. In 1927, however, the current of Robertson's scientific activity was turned into a new channel hy his acceptance of an offer from the Commonwealth Council of Scientific and Industrial Research to become chief of a department of Animal Nutrition. Under his direction a laboratory was erected on the University grounds facing Victoria Drive, and here, with the help of a small band of assistants, he planned and inaugurated a plan of experimental work in the ficld and in the laboratory. ‘The final objective of this work is to augment the wealth which Australia derives from the sheep-breeding industry, but Robertson rightly insisted that this result would be most surely and effectively reached by a broad scientific inquiry into the relations which exist between the various dietetic factors and the growth of the animal or the quantity and quality of its wool. On these lines the work has been proceeding, and already results have been obtained which testify to the soundness of his views and indicate the possibility of large economic returns. Robertson’s interests were by no means confined to the bounds of his special science. He read widely, though eclectically, both in scientific and imaginative literature. Such a book as Upton Sinclair's “Arrowsmith,” in which the commercialism sometimes associated with scientific research in 195 America is scathingly arraigned, gave him huge delight, and one of his latest essays published in the “Hibbert Journal” deals trenchantly with the same theme. * Robertson’s published works, in addition to the very numerous papers descriptive of his experimental researches, include text books on “The Physical Chemistry of the Proteins” and “The Principles of Biochemistry.” He took an active part in the social life of the University, and was instru- mental in founding the Graduates’ Association, the University Club, and the Medical Sciences Club. The “Australian Journal of Experimental Biology and Medical Science,” which serves as the organ of publication for all Aus- tralian workers in this field, was established under the aegis of this last body. In 1926 Robertson was honoured by election to the Reale Accademia Nazionale of Italy. “His life was gentle and the elements So mixed in him that Nature might stand up And say to all the world, ‘This was a man!” KERR GRANT, THE SIR JOSEPH VERCO MEDAL. The Council, on August 23, 1928, having resolved to recommend to the Fellows of the Society that a medal should be founded to give honorary distinction for scientific research, and that it should be designated the Sir Joseph Verco Medal, was submitted to the Society at the evening mecting of October 11, 1928, and at a later meeting, held on November 8, 1928, when the recommendation of the Council was confirmed on the following terms :— REGULATIONS, XI.—The medal shall be of bronze, and shall be known as the Sir Joseph Verco Medal, in recognition of the important service that gentleman has rendered to the Royal Society of South Australia. On the obverse side of the medal shall be these words: ‘The Sir Joseph Verco Medal of the Royal Society of South Australia,’ surrounding the modelled portrait of Sir Joseph Verco, while on the reverse’ side of the medal thcre shall be a surrounding wreath of eucalypt, with the words: ‘Awarded BOE ants Me hdl sig a geigamectannin Bie S8O rd ananneoall le ea Be for Research in Science,’ the name of the recipient, and the year of the award. The Council shall select the person to whom it is suggested that the medal shall be awarded, and that name shall be submitted to the Fellows at an Ordinary Meeting to confirm, or otherwise, the selection of the Council, by ballot or show of hands. The medal shall be awarded for distinguished scientific work published by a Member of the Royal Society of South Australia.” ‘OL6L ‘€ 2990790 ‘OprEPpPy ae fen ‘ssoupny [ _LLaMDVH NOIdNVHO “M winseoiy UoH “HOVOU 'S 4 uwH ol WIA “STV'V ‘AUMNUNOLSVID ‘O ‘4991109 Puno} pue poyipny 196 Ll ope lF Ll OPP l¥ 9 2 ere a2. 2 ge ee bean Tae ¢ Of &£ 6¢ I | “ (sanbeyD Buspurising $s9'J) l Z 0 SRF eisepesysny jo yueg I FI 999 "" BHedsny YINOS JO yurg ssuraes —OL6I ‘Og Jequiaidas ‘gourjeg ‘ O1S 62 0 + 0 a “aie ‘“ sareday [[eurs ; 0 ST 9 tp - sotreimsuy T S ele 0 flel Aou0nNS pue Sasa ‘Buruig ¢ £ S8t pund juourmopuy WoL] Paisajsuesy, OL €1 Z pa Bunysry pue Buyuesy) 6 £1 £2 a yunosy yueg sSuraes —soalipuns ‘ —jsalajuy “ 8 6! 641 8 OF 02 0 Slap = - dat ssajeysS MON 8 9 i ae suoneoyqng jo apeg “ 0+ TI Ka “o | SOURIS yo qrounos) anZoejep 9 2 + a “> sa1pa190G Joyjo Aq WOOY jo 28/) ¢ 8 8 I - — “ salnq suroysn) 6 et LL 0 r of a au se Sulpurqyoog 0 0 OST ea SUOTRAISOAT] 0 8 pOlL ot ae rid uelieaqry oyitorS pues sjiodoy Sutjulg 404 —Areiqvy 6 €.

SUGGESTIONS FOR THE GUIDANCE OF AUTHORS IN THE PREPARATION OF MSS. TO BE SUBMITTED TO THE SOCIETY. 1. The manuscript must be clearly written (especially in the case of scientific and technical terms), and in a form ready to be placed in the hands of the printer. It is a great advantage for MSS. to be typed, double spaced. If the paper be illustrated, the illustrations, maps, ete., must be supplied in a form ready for reproduction. Where reduction is required, detail and lettering must be pro- portionally enlarged. It may be necessary to return MSS. to authors for typing. In returning proofs to the Editor, the original copy should be included. 2. Uniformity must be preserved throughout in the use of capital letters, italics, abbreviations, punctuation, ete. 3. All generic and specific names must be underlined (denoting italics). Other scientific nomenclature must be in roman, Generic names must begin with a capital letter, and specific and varietal names (even where a proper name is used) must begin with non-capitals, as, for example, Lovenia forbesi T. Woods. (An exception to this rule is made in the case of botanical names, where the usage is to retain the capital letter in proper names.) 4, Diphthongs are not allowed; each vowel must be written separately, as, for example, Archaeocyathinae. 5. In the case of original descriptions the following abbreviations should be used: n. gen., n. sp., m. var. 6. Authors and authorities, following a name in roman, must be in italics; following a name in italics, to be in roman; when the species is transferred to’ another genus the name of the original author to be enclosed in parentheses. (No comma shall appear between the specific name and the name of the author.) 7. The names of Australian States are to be written in full in the text, but in the footnotes and synonymy are to be abbreviated as follow :—Australia, Aust.; New South Wales, N.S.W.; Victoria, Vict.; Tasmania, Tasm.; South Australia, S. Aust.; Western Australia, W. Aust.; Queensland, Old.; North Australia, N. Aust.; Central Australia, C. Aust.; New Guinea, N. Guin.; New Zcaland, N.Z.; Federal Capital ‘Verritory, F.C/1. Aust. 8. Symbols or abbreviations used to save trouble in writing, but not intended to appear as such in the printed text, are not allowable. 9, The maximum size of illustrations (maps excepted) to be 74 inches x 5 inches for plates, and 73 inches x 5 inches for text figures. 10. Papers submitted to the Society for reading must be lodged at the Society’s rooms at least a week before the meeting of Council, which is held on the fourth Thursday in each month, from March to November, inclusive. - Note regarding Abstracts—YVhe author is requested to supply two brief abstracts of his paper—one for local usc, and another, not exceeding 50 words, to be sent to publications which cannot grant more space. 207 LIST OF FELLOWS, MEMBERS, ETC.

FORTY-SEVENTH ANNUAL REPORT OF THE COMMITTEE FOR THE YEAR ENDED AuGust 31, 1930, MEMBERSHIP.—Last year’s membership was 150, of which total 110 were financial, This year’s total membership remains about the same, taking into account the losses by resignations and the new members elected. Excursions.—Various trips were undertaken during the year to places of interest, and visits were made to the Botanic Gardens and Museum. The Com- mittee also reluctantly decided to abandon the motor trips, on account of the losses involved through not being sufficiently patronised to justify a continuance of these excursions at present. LecrurEes.—We have been favoured with an interesting series of lantern lectures during the period under review, as follows:—“The Stellar Universe,” by Professor R. W. Chapman, C.M.G., M.A., B.C.E., FLR.A.S.; “The Architec- ture of India,” by Rev. J. H. Allen, B.Sc.; “Honolulu, California and Arizona,” by Dr. R. H. Pulleine, M.B., Ch.M.; “A Trip to Cairns,” by Mr. A. J. Morison; “The Phenomena of the Atmosphere,” by Mr. A. G. Edquist; “The Association of Insects with Plants,” by Dr. James Davidson, D.Sc. Others who have assisted with lecturettes were:—Mr. A. M. Lea, F.E.S., on “Some New Guinea Insects” ; Professor J. B. Cleland, on “A Trip to the MacDonnell Ranges”; Mr, J. G. Wood, on “Wallace’s Line”; Mr. E. S. Thomas, on “Native Timbers”; and Dr. C. ‘Fenner, F.G.S., on “Some Australian Fossils.” Exurpits.—Several members have contributed to this portion of our pro- gramme, and we are at all times pleased to have members bring exhibits. “Tue Sourm AUSTRALIAN NaTurAList.”—Our Journal has been published regularly each quarter, under the editorship of Mr. Ham. The part to be issued this month will complete volume IJ. Witp Frowrr Suow.—The 1929 Annual Show was held on October 10 and 11 in the Adelaide Town Hall, which was made available by the kindness of the Lord Mayor. The standard of past shows was well maintained, and resulted in a successful function. The balance-sheet showed a profit of £39 8s. 4d., which was between £5 and £6 in advance of last year, Herparium.—The work in the Herbarium has been continued, several meet- ings have been held, and the arranging and mounting of specimens have been proceeded with. AUSTRALASIAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE, BRISBANE, May-June, 1930.—At these meetings the F.N.S. was represented by Messrs. J. Bailey and A. G. Edquist. RESIGNATION OF SECRETARY.—During the year the Section sustained a great loss, when Mr. E. H. Ising tendered his resignation as Honorary Secretary, after 12 years devoted service, dating from December 31, 1930. At a later date an opportunity was taken of making a presentation to Mr. E. H. Ising in recognition of his services. We have, however, been fortunate in securing his services as 212 Show Secretary for this year, as his past experiences in Show work will make his help in this capacity a very valuable contribution to the success of our 1930 Show. New SEcRETARY.—Following Mr. Ising’s resignation, nominations were called for through “The South Australian Naturalist” for the position of Hon. Secretary, without response. At a meeting of the Committee, held on January 15, the undersigned consented to take the position of Acting Hon. Secretary, and has continued to act in that capacity. H. Woopianps, Acting Hon. Secretary. August 19, 1930. ANNUAL REPORT OF SHELL COLLECTORS’ CLUB FOR THE YEAR ENDED Aucust 31, 1930. There were 21 meetings during the year, with an average attendance of 12. Gastropods have been under review, and the following families have been dealt with, viz.:—Pleurotomariidae, Fiasurellidae, Haliotidae, Stomatidae, Thochi- dae, Turbinidae, Liotiidae, Neritidae, Acmaeidae. Members of the Club invite those who have an interest in shells to join with them on the first and third Mondays in each month. (Signed) W. J. KimBer, Chairman. F, K. Goprrey, Secretary. ANNUAL REPORT OF THE MICROSCOPE COMMITTEE. The activities of the Microscope Committee of the Field Naturalists’ Sec- tion extended throughout the year 1930, and the meetings maintained the usual regular attendance. Early in the year the Committee was approached by the President of the Legacy Club with a view to interesting the boys in microscopic matters. Mr. Harding, assisted by divers members, arranged a number of lectures that were well attended, As a result of these efforts it was felt by members of the Com- mittee that it would be fitting if the ordinary meetings of the Committee were thrown open to any of the lads who were interested, with the result that a large number, in charge of Mr. Shepherd, attended regularly. The Committee was fortunate in obtaining the services of Mrs. Best, of the University staff. On one occasion a highly instructive lecturette was delivered on “Parasitology,” and on another occasion the subject was “Single-celled Animal- culae.’ Both lectures were amply illustrated with slides and specimens. On the occasion of the latter lecture the Committee joined with the Aquarium Society, and a very large gathering was present. Mr. Machell, of the Education Department, was also kind enough to give an evening on “Aquarium Life,” which was highly appreciated. An outline of Natural History, as taught in the schools of the State, was also given. The thanks of the Committee are due to the Vice-President, Mr. W. A. Harding, who so kindly placed his microscopic projector at the disposal of the Committee. The instrument enabled large images of remarkable accuracy to be thrown on a screen, thus greatly facilitating the observation of the slides by the members. (Signed) Frank B. CoLtins, Hon. Secretary Microscope Committee. 213 “SoInsealy, ‘UOH ‘XIC “A ‘| (pausis) ‘oanyipuadx ay 6 ZI IF 6 ZI IF € 610 de Aes is tat a“ : diay youneq ' ST ‘G24—Ofl6L 6 Z10 WOT AO sso JO ssooxay “ 9 €10 i “ a inte Mi STTMOD “AE 0} diay 0 0 7 7 “ dity o8ury wyAseg oy ‘£ ‘Wd9S—6Z61 Of “AON—6Z6T ‘Pp S F ‘PS F *SOSSO'T ‘s]yoIg “SENNODDV NOISHNOXG ; ‘O€6T ‘OL asnsny ‘preppy INH@qvoudd ‘H WVITIIM ‘sioypny) (sity) Jueluno.y patayieqa ‘daau ‘a UALTIVM (pausis) “OMSPITT UOH 'XIC ‘A “A (pausig) ‘4931109 punoy puke payipny 8 ZI cOly 8 LE cOlF 6 ZL0 ay ras aah “" $8O"7T JuNODDY UOoIsInoxy” “ 0 ST ¢¢ i ne Ayato0g yekoy “ Z Zit sasuadxq Suypaaery 0 610 ” syoog Aieiqry “ 0 Zt asey) SlepulLy ‘worjdayjoy “ 0zt asey Slapulpy JOy uoljoaljo> eune,y pue e1opy 9 zZ1Zz ai aes ae saspeg “ 0 0 - aS, ~ Ti rH fi sadpeg “ 8 9 0 Sees IsyeInjeN -w's,, “ TT 819 UloyueTy pue [ey jo onpy “ r 8 6¢ it é MOUS Jomo, “ 09 ¢ as Mike “" @UIsILIeApy ‘ Z, C2e Jsalojuy yueg “ 9 ¢€1 92 AIQUOIeIS pue suyung “ 0 SI ¢¢ stotjdisosqng “ 0 ST9 ass, ‘230 ‘soseysog Ag 0 8 +z IPa A ISVT woly sauyeg of ‘P'S F ‘Pp 'S F ‘sjdiadayy “O£6T ‘TE ISNENy pepus 1e9_ 34} 10} ainjipusdxy pue sjdiaoayyz jO JUsUId}E1g (AALVUYOdUOONI) VITVULSOV HINOS TO ALHINOS IVAOW AHL JO NOLLOGS SLSITVYALVN CTalg 214 GENERAL INDEX.
