By John Bostock, M.B., B.S., D.P.M., Department of Medical Psychology, University of Queensland. (Delivered before the Royal Society of Queensland , 21th March , 1944.) Before proceeding with the Presidential address of the Royal Society of Queensland, which I am privileged to give, I wish to place on record two outstanding events which have occurred during the past twelve months. The government, through our Premier, the Hon. F. A. Cooper, has made a substantial grant to the library of the Royal Society, in order to assist in the preservation of our records which are regarded as being of vital importance to the scientific world of Queensland. With regard to the war, it will interest all members to know that your president and the council pledged themselves to assist not merely in the war effort but also in any scheme for the improvement of library facilities in our state. The year has seen the passing of the first secretary of the Society, Mr. Henry Tryon. It is regretted that he did not live to present an account of those early days. He Rad promised to do this. No reference to Mr. Tryon would be adequate without mention of the sterling qualities he possessed. Among them were his perseverance in the face of obstacles, his courage and the wide variety of his scientific interests. THE ADDRESS. In choosing as my theme for this evening “A Retrospect of Modern Psychiatry,” it has been my desire to introduce one which illustrates that wide scope of enquiry which not merely underlies the scientific ideal but is the guiding principle of the Royal Society itself. Whilst no one can deny the advantages of specialism, there is no doubt of the danger that it may be purchased at the price of isolationism. All too frequently we are dragooned by the urgent necessities of our calling and the limitations of the time factor into an intellectual privacy which has harmful results. The meetings of our Society are a valuable means of combatting this tendency. It will be my endeavour to show in this study that psychiatry illustrates the wide variety of scientific contacts which are necessary if progress is to ensue. Attention will be drawn to certain principles of research. To-day we are apt to think of streamlined systems which flow inexorably if not effortlessly to a desired conclusion. This does not apply to research which is often hampered by over-planning. o u PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. Progress is discontinuous and at times erratic. Discoveries are kept for decades in the cold store of forgotten memories. Research in one field produces results in unexpected places. Above all we are reminded that all knowledge is interrelated. The observation of a fruit may give clues as to the working of a planet, the study of a flea may permit the saving of a million human lives. Such facts are reminders of the need for intellectual freedom without which progress cannot escape the strangle-hold of outworn tradition. PSYCHIATRY DEFINED. I propose in this address to give a brief retrospect of modern psychiatry, touching on changes which have occurred during my own lifetime and largely during the period I have been a practising psychiatrist. It will be seen in the course of this retrospect that the psychiatrist has borrowed profitably from the bank of science. Psychiatry is a field of medicine whose boundaries are extensive but vague and ill-defined, for at the one extreme we see conditions which are entirely functional, being unassociated with demonstrable physical change, and at the other there are grossly organic diseases. The psychiatrist is concerned with the disorders of a psycho-somatic (or mind-body) nature, not with diseases affecting tissues or organs, or systems of organs. In fact he is dealing with the total reaction of patients as social or biological units. The total reactions of individuals are designated as behaviour. The purpose then of psychiatry is to study and treat conditions characterised by disordered behaviour. Biologically considered, behaviour is the product of the reciprocal reactions between the organism and its environment. As pointed out by Dr. S. E. Jones the reactions have a double polarity, for the individual modifies and acts upon his environment and the environment acts upon the individual. This double aspect is important in psychiatry because behaviour disorders are largely determined by the influencing of environment on the individual. Thus it wall be seen that psychiatry is concerned with highly complex relationships over a very wide field from that of the welfare of the individual to that of the entire community. GENERAL PARALYSIS OF THE INSANE. It is fitting to commence this retrospect by a consideration of General Paralysis of the Insane for it was the first psychiatric entity to be identified. The clinical and pathological changes were completely defined in 1826. When I first took up a position in a large mental hospital, it was a common sight to see rows of beds in which general paralytics were lying, paralysed in body, bankrupt in mind, surviving in mere vegetable fashion and awaiting the inevitable termination in death which came within a year of hospitalisation. To-day the young psychiatrist rarely sees such a case. The course of this disease has been entirely changed. The steps toward this truly dramatic alteration in outlook are intriguing. It was not until late in the 19th century that syphilis was generally accepted as the cause of this disease. Previously many authorities regarded it as due to the ‘ ‘ stress of modern life 9 ’ owing to the fact that it was most common in members of the learned professions and Army officers. A RETROSPECT OF MODERN PSYCHIATRY. 3 We read that in 1893 Kirchoff considered “the development of the disease is favoured by the noxious influences inherent in the agitated life of recent times. ’ ’ The view that syphilis was responsible was strengthened by the application of the Bordet-Gengou or Wasserman Reaction and was ultimately confirmed when in 1913 Naguchi and Moore demonstrated the presence of spirochaetes in the brains of general paralytics. It will be seen that a period of 90 years elapsed between the recognition of the disease entity and the elucidation of its aetiology. Although the proven remedies for syphilis were employed with many variations, including the arsenicals “606” and later derivatives of the Erhlich and Hata discoveries, the curative results were entirely fruitless. A diagnosis of General Paralysis still remained the equivalent of a death sentence. The first rays indicating the dawn of therapeutic success were ushered in in 1917 when publicity was given to the success of Wagner von Jauregg in treating this disease by inoculating his patients with malaria. Many years earlier he had suggested the use of fever for the treatment of this disease. This suggestion was based on the quite common observation that a patient suffering from mental disorders frequently had a remission of symptoms in the course of or following an intercurrent febrile disorder. VICTORY THROUGH HEAT. At first we thought that the malarial infection had a specific antagonism to the spirochaete of syphilis. Later it was shown that equally beneficial results were obtained by other methods for inducing high temperatures. A wide variety was used including relapsing fever, typhoid inoculations and bacterial products. Later (in 1930) pyrexia was induced by diathermy and air-conditioned chambers. Finally the property of the electric short wave (25 metres) was used. It now seems obvious that the curative agency is heat, ,,in that a temperature of 106° F. is fatal to the spirochaete. It is interesting to reflect that Louis Pasteur discovered the delicate relationship between organisms and the temperature of the medium in which they live during experiments with Anthrax. He noticed that the bacillus can he grown in cultures only with great difficulty at temperatures of 43° C. or 44° C. It occurred to him that this might be the explanation for the known immunity of fowls from anthrax. The normal temperature of fowls is 42° C. On March 19th, 1878, Pasteur demonstrated two fowls which had been plunged into the same bath at 25° C. One was inoculated with 5 drops of an anthrax culture. It contracted the disease and died whereas its control companion suffered nc disability. Here we see a hint on a direct approach on the therapeutics of infection yet it was only applied many years after publication. This story of victory over disease by heat illustrates the inter- relationship of the science in which the biologist and the chemist have played a prominent part. We might emphasize the place of the physicist. The story of the evolution of wireless is familiar to most. Even the comparatively young will remember Marconi's conquest of the Atlantic and the arrest of Crippen as a dramatic result of this new method of 4 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. communication. I must confess an inability at that time to conceive that a radio transmitter would a few years later be curing Dementia Paralytics. Electro-magnetic induction was tried by Neymann, Osborne and Holmquest in 1928. Those who have seen this type of treatment will confess that it savours of the miraculous. The heating element is a loop or coil resting on the blankets. The following is the description of a technique used by Guy P. U. Prior, and recorded in the Year Book of Neurology, 1937 : — ‘ ‘ The patient is insulated against loss of heat by use of terry cloth, a rubber sheet and six blankets which are wrapped around him and around which 3 turns of the cable are laid. The patient is given a hot bath, an enema, 10 ozs. of hot milk or coffee and 6 grains of Sodium Heberal two hours before treatment. Pulse, respiration and temperature are recorded every 15 minutes and a hot drink consisting of glucose 10 per cent in Saline solution 0-6 per cent, is given freely. The temperature must be kept about 103-4° F. for 8 hours and during 2 of these hours it is between 105-2° and 106° F.” As a result of such modern methods, the patient suffering from General Paralysis has now a positive prospect of arrest of the disease. This improves in ratio to the time from onset of symptoms. The early treatment produces the best results. Such considerations have a significance to-day. COMING SHADOWS. We are used to those financial taxes which are an inevitable concomitant to the war effort. We may fail to remember those invisible taxes which burden the national health. War produces a bounteous crop of syphilitics from which wdll follow a future harvest of general paralytics. In 5, 10, 15, or 20 years, we may expect to see cases which illustrate- the classic train of symptoms. Let us hope that our prophylaxis will be as perfect as possible, that our heat therapy so ably commenced will improve through the years. We may find that every syphilitic should receive heat therapy in order to sterilise that nidus of brain infection which, lying dormant for a decade, can awake, we know not why, to virulent activity and produce those deadly results to which I have referred. It is not surprising that efforts have been made to utilize the converse effects of cold therapy. Patients have been placed under conditions of extreme cold for Jong periods. Whilst good results have been claimed, the dangers of pneumonia and other complications have militated against success. SHOCK TREATMENT. Twenty years ago in the wards of every psychiatric hospital, in the outpatients of every psychiatric clinic and indeed in every doctor’s consulting room were cases in which the treatment was of the “By God and by Guess variety,” a compound of hope, time, aperients, fresh air and drugs. One would see — A RETROSPECT OF MODERN PSYCHIATRY. 5 The melancholic, who for months or years, would remain emotionally depressed, indifferent to life, often indeed actively searching for death or A young man in the prime of life, weighed down by such a load of anxiety, that a decision became impossible and even interesting work could not be undertaken through his inhibitions and disinterest or A woman whose chief thought was the means of killing her children lest they too would suffer or A man the victim of a ceaseless obsession that he must perform an act of antisocial nature, which must inevitably produce his ruin. We have seen such cases in hundreds, nay thousands. Whilst cure often ensued, it's course was slow and unpredictable. Often the coroner’s court and the mental hospital were the final repository. We have prayed earnestly for a magic philtre which would disperse the evil cloud of depressive thought and make the obsession recede beyond the ken of consciousness. To-day our prayers have been answered through the modern miracle of shock therapy. The word “ Miracle” is not an indication of enthusiasm run riot but of sober fact tempered by experience. With shock therapy each patient I have mentioned has the probability of freedom from symptoms within two or three weeks. Within a week the suieidally inclined, the child-murderer, the anxiety-ridden and the obsessed may be taking a cheerful intelligent interest in their surround- ings and be so divorced from their depressive past as to forget entirely their morbid thoughts. Within the last ten years, the advent of shock therapy has com- pletely revolutionised the practice of psychiatry by eliminating the time-lag of the old proceedings and creating an early atmosphere of enthusiastic co-operation. The story behind shock is another admirable illustration of scientific progress, its interrelationship with other branches, of unexpectedness and lack of continuity. In the year 1781 a William Oliver of London described that a case of mania improved after a course of camphor had given convulsions. 150 years were to elapse before the technique became common practice and then it was introduced almost simultaneously by two independent workers on different lines. In 1928 Manfred Sakel was using Insulin in the cure of drug- addiction and found that sometimes when large amounts are employed severe hypoglycaemic shocks and convulsions produce remarkably successful therapeutic results. Prior to 1932, it had been noted that if convulsions occurred in a case of Catatonic Schizophrenia, there might be a remission, and that remarkably few epileptics suffer from this common mental disorder. In 1933, von Meduna, after experimenting with animals, injected an intra-muscular camphor preparation (25 per cent, of oleum cam- phoratum) into a series of human patients. The method was clumsy since the convulsions were uncertain. Soon it was replaced by intravenous cardiazol — pentamethylene tetrazol — in 10 per cent, solution. A list of favourable results was published. The treatment soon swept the world and was tried in many thousands of cases. Gradually the relative scope of usefulness for Insulin and Cardiazol was mapped out. It was discovered that although the latter was designed for 6 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. Schizophrenia, the best results were obtained in other conditions. In spite of inherent risks of fracture or dislocation, cardiazol achieved the wider usage on account of ease of administration and safety to life. In cardiazol therapy the convulsion occurs within 20 seconds. The patients wake up in a few minutes and can get up. They need not be confined to bed. In insulin therapy very large doses are required and highly skilled medical and nursing attention is needed for five or six hours. As coma is induced little imagination is required to realise the risks involved and the necessity for a standardised technique. Although the psychiatrist was gratified with the new therapeutic methods, he began to pray for a modification. Cardiazol creates fear of the treatment in the minds of the patients. We also wanted a greater immunity from fractures and dislocations. Again the physicist rose to the occasion. Cerletti and Bini, in 1937, experimented with the use of alternating current through the brain for the production of convulsions. They found that this was an effective agent and had certain advantages over the pharmacological method. In brief, the alternating current is passed trans-temporally at a voltage ranging from 90 to 200 for a period of time from -1 to *5 seconds. Immediately the current is passed the patient becomes unconscious and herein lies the great advantage over the injection method. The effect being instantaneous, the patient experiences no discomfort. If the preselected voltage and time are adequate, a convulsion commences within a few seconds and lasts for f of a minute. THE ELECTRO-ENCEPHALOGRAPH. Twenty years ago the psychiatrists envied the cardiologist for the possession of the electro-cardiograph which, by registering differences in electrical potential, gave an accurate measurement of heart-action. We prayed for some such instrument in order to wrest the hidden secrets of brain-function. Our only recourse was through brain-sections under the microscope, the X-ray which merely revealed shadows and the newly developed technique of encephalography wherein the injection of air into brain and spinal cavities increased the scope of such shadow- pictures. These measures, whilst helping in the elucidation of brain- substance, could not give a hint of the underlying dynamics. A commencement to new knowledge was made in the early thirties of this century by recording electric variations in skin reactions whilst the patient was influenced by stimulating ideas. It was found that there is a relation between emotion, anxiety, and skin resistance. The much publicised “Lie detector” is a variant of this type. In 1934, Hans Berger revolutionised the field by his use of an oscillograph which minimised the effects of skin resistance. He was able to show the presence of two types of electrical oscillations. The most obvious of these is the “delta” which consists of rhythmic changes in electric potential from 0 to 100 microvolts at a frequency of 10 per second. In most people the waves are only present when the eyes are closed and the mind at ease. The “beta” waves are smaller and of .a frequency of 18 to 25 per second. They are associated with the Frontal lobes. The use of the Electro-Encephalograph has already borne fruit. It is being widely used in the localisation of cerebral tumours and as early A RETROSPECT OF MODERN PSYCHIATRY. 7 as 1936, Grey Walter was able to report four cases in which slow waves pointed to the site of a growth which was verified at operation or post mortem. Light has been shed on the age-old, mysterious yet very common condition of Epilepsy. It has been shown that the fit or seizure is but the outward manifestation of disorder in brain-rhythm potentials. Major and minor attacks show an increased voltage during its height. It is possible to differentiate by the wave-speed, those vague muscle jerkings, bouts of irritability and other minor variants which are a part of the Epileptic Syndrome. As a result of these discoveries, epilepsy is now described asa“ Paroxysmal Cerebral Dysrhythmia. 7 7 The encephalograph is to-day being used not merely as a help in diagnosis and treatment but has been employed medico-legally to discover epilepsy in the criminal. During a recent case choice of the alternatives “prison or hospital” actually depended on the encephalographic findings. Quite apart from the above one must refer in this retrospect to the extraordinary change in outlook for the epileptic during the last 25 years. Only those who remember the “era of the Bromide7 7 will appre- ciate the dull intellects, the spotted faces and demented appearance of the old-time sufferer. To-day through the introduction of the Barbiturates and Dilantin we have at our disposal drugs which will in most cases control the fit without producing an excessive drowsiness. DISCOVERY OF NEW ENTITIES. Time passes. I must all too briefly refer to the well-known scientific process of collecting facts, analysing the material and splitting off entities into a new classification. Thirty years ago any of the following patients would have been wrongly classified and treated: 1. A man has had only two fits in his lifetime both when surfing. 2. (a) A fireman complains of faintness only when stoking his engine. He is nervous. (b) A woman having once been giddy in the street develops fear of going out of doors. 3. A man falls to the ground when excited and falls asleep on the least provocation even when driving a car. 4. A young adult, after a severe attack of “fever,” sleeps by day, is awake at night and becomes clumsy in his move- ments and sees “double.77 Case 1. — The cause and treatment of Diabetes is now a common- place of knowledge. The use of Insulin in decreasing excess of blood-sugar is universal. That psychiatric states can result from a decrease in blood-sugar is a new discovery. The man mentioned above who, after heavy exercise when fasting, had fits was found to have a low blood-sugar/ He is not an epileptic but a hypoglycaemic who by regulating his food-intake can command his destiny. We now know that hypoglycaemia can produce a wide variety of symptoms including mental confusion, langour and pains. Case 2 ( a and b). — Both have previously been treated as merely nervous invalids. Actually they belong to the “water-balance syndrome.” Our stoker loses much sweat in the hot task of feeding his engine in a tropical condition. He has merely a salt-deficiency. The 8 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. lady suifers from water-pressure change in her semicircular canal. If she excludes salt from the diet and uses a substitute for the Sodium radicle, the giddiness will disappear. The fireman must take more salt. Case 3. — Twenty years ago a sleepy man who, because of nervous- ness, could not smash with a racket or hook a fish was just another example of “ nerves/ 9 Now we see the characteristic story of “Idio- pathic Narcolepsy ” for which there is a specific remedy in Ephedrine or Benzedrine. Case 4. — To-day the combination of fever and drowsiness followed by character changes is so clear that even the tyro can make a diagnosis of sleeping sickness or Encephalitis Lethargica due to an infection of the brain. Such cases and their variants are quite common. It is interest- ing to note that the first recognition occurred by Constantin von Economo in 1917 and was later identified with a “mysterious disease,’’ occurring in Australia in the same year. As Professor Economo says: — “Every psychiatrist who wishes to probe into the phenomena of disturbed mobility and changes of character, the psychological mechanism of mental inaccessability, of the neuroses, etc., must be thoroughly acquainted with the experience gathered from Encephalitis Lethargica. Every psychologist who in future attempts to deal with psycho- logical phenomena .... and is not well acquainted with encephalitic patients .... will build on sand. ’ ’ Had I the time, I would have liked to describe other entities, such as the role of vegetable or animal extracts (or chemical substitutes) and vitamins in assisting the psychiatric patient. It is not merely in those serious cases such as Pernicious Anaemia or Myasthenia Gravis that the new knowledge has been important. To-day the woman in every home who is going through the menopause can do so with an ease unknown to her mother. We are beginning to use the endocrine glands with good and indeed often brilliant results. Concerning Vitamins, the discovery of the B1 and B2 complex has opened new avenues of treatment. With their aid we can achieve the hitherto impossible. It is spectacular to see a crippled neuritic almost take up his bed and walk. It is satisfying to be able to help the array of the debilitated through the avitamosis of a faulty diet, take on a new life of increased happiness and efficiency. Were the time available it would be profitable to discuss the problem of allergy, which relates to our sensitivities toward a wide series of sub- stances, both in the body and without. We are realizing such mechanisms may give headaches and other symptoms. Often the patient manufactures his own poisons. THE SOCIAL SPHERE. The above references will I trust serve to emphasise the wide scope of psychiatry and its linkage with diverse studies. I shall conclude by drawing your attention to the extraordinary change which has occurred in our appreciation of the psychology of man the individual and of man in the mass. There has been a profound revolution in our viewpoint, so that we are beginning to see the world as it is — a correlated living A RETROSPECT OF MODERN PSYCHIATRY. 9 whole and not as a mere aggregation of separate individuals living separate lives. Such change did not occur overnight nor is it complete. Whilst it is true to say that psychiatry has outgrown its swaddling- clothes and can use its eyes with advantage, it cannot see all, but the same might be said of all departments of knowledge for there is always further knowledge over the horizon. During the latter part of the 19th century, psychiatry was largely based on materialism. This attitude persisted into the present century as may be seen from the attention given in the journals to brain structure and clinical tests. It is true that Braid and Bertrand pro- duced mesmerism by suggestion and coined the term hypnotism but this psychological attitude was unusual. It received an impetus through the impressive work of Charcot in the seventies and eighties on hysteria and hypnotism. Following this one must chronicle the activities of a group of men who hammered the psychological viewpoint to a point when it dominated the entire psychiatric picture. We must include Babinski, Dubois and Dejerine, Coue, Janet, Adler, Jung, Morton Prince, Watson, McDougall, Rivers and Freud. It must be conceded that spectators on the arena of the psychiatric battleground have had a remarkable experience. As each teacher advanced his views he collected followers who formed a “ school of thought.’ ’ Whilst at the time, this differentiation seemed reasonable, to-day the lines of demarcation seem tenuous and flimsy. Through death the colourful and forceful leaders have departed, leaving us free to abstract from each according to our needs and to collate without prejudice or bias. Only the mentally blind will deny us the existence of a glorious heritage. As this is a short personal retrospect, one cannot be expected to give honour to all. One must mention Freud for his dynamic concept of the striving soul, impelled by the race-need for reproduction, Rivers for his insistence on the importance of current happenings to the psyche, MacDougall for stressing the variety of emotional and instinctive forces which pattern our lives, Adler for teaching the role of inferiority striving for recognition, Dubois for his realisation of the power of persuasion, Watson for showdng the importance of the study of animal behaviour, Kraepelin and Janet for indicating the need for careful case-taking in medical records, Binet and Simon for demonstrating that any careful analysis may have far-reaching results, Jung for his analysis of psychological types. It must not be thought that the ranks of the materialists were silent during the period under review. Kretschmer stressed the importance of body-type on character and temperament. The endocrinologists draw our attention to internal secretions which dominate personality. Cotton and Robertson will not let us forget the devastating role of constipation and focal sepsis. Our dietitians thundered the need for a balanced intake of food. To-day, thanks to this spate of ideas, w^e are able to survey the wdiole field of human endeavour and envisage each problem in an appropriate setting. Our knowledge of the bipolarity of our lives, the interrelation of cause and effect, between self and environment, between “I, you and they, our betwixt and betweens and surroundings” has created the new psychiatry B 10 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND which is concerned equally with social customs as with individual usage. Thus the prevention and cure of a disease may be visualised as the need for alteration in the social way of life and not merely an occasion for individual chastisement or re-education. When the psychiatrist is asked the secret of a nervous and mental disorder he can discuss beyond the immediate remedy to plans for future needs . . . more educated parents, early training on right lines for children, better homes, better modes of living and surer routes to the goal of individual and race happiness. If it is ever justifiable to deduce future events from past per- formance, one must regard the future of psychiatry with an interest which should not be enclosed within the narrow confines of a single specialty. Ajs Sir James Mackintosh pointed out more than a century ago : — - “Diffused knowledge immortalizes itself.7’ And so in conclusion we return to that movement for freedom for knowledge and its dissemination among other scientists which has been the guiding rule of the Royal Society.

( Received 6th March , 1944; read before the Royal Society of Queensland, 31s£ July, 1944; issued separately 13 th November, 1944.) The genus Streptachne R.Br. Prodr. 174 (1810) was founded on a single species S. stipoides R.Br., l.c., though other plants have1 been referred to this genus by later writers. The interpretation of this genus and species has been a source of difficulty almost ever since, and in this paper an attempt is made to throw some light on the taxonomic and nomenclatural problems involved. The data available for the taxonomic interpretation of Streptachne stipoides R.Br. are as follows : 1. Throughout the literature no specimens other than the type- gathering have been referred to this species. 2. Robert Brown, Prodr. 174 (1810), states that the specimens he saw were in the herbarium of Joseph Banks. The name of the species is merely listed (without a specific descrip- tion) after the description of the genus, of which the most important phrase is “valvula exterior cylindraceo-involuta, arista terminali simplici inarticulata infra tortili” and the observation “Gramen facie Aristidae v. Stipae ab hac diversum arista cum valvula inarticulata. ’ ’ 3. Bentham, FI. Austral, vii. 571-2 (1878), follows Brown and writes that the species is 1 ‘ only known from two very imperfect specimens, one in Herb. Banks, the other in Herb. R. Brown, each consisting of the summit of a stem without leaves, bearing a very slender and loose little-branched panicle of 5 to 6 in. Outer glumes 4 to 5 lines long, tapering into long fine points. Flowering glume narrow, glabrous, tapering into a very fine twisted and bent awn of f in. Stamens 3.” The locality is given as Endeavour River. 4. F. Mueller in Journ. & Proc. Roy. Soc. N.S. Wales xv. 237 (1882), cites Streptachne R.Br. as a synonym of Stipa L. 5. Domin, in Biblioth. Bot. xx. heft 85, 342 (1915), transfers the species to Aristida as A. streptachne n. nom. and thus describes the specimens: ‘ ‘ besitzt fein zugespitzte, gleich lange eirciter 11-13 mm lange, kahle Hullspelzen, von denen die eine dreinervig, die andere einnervig ist. Die Deckspelze ist mit den Hullspelzen fast gleichlang und geht .... in eine einfach, im unteren Teile spiralig gedrehte Granne liber.” c 32 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. 6. Hughes, in Kew Bull. 1922, 302 (1922), discusses the genus and its relationships with Stipa and concludes that it is distinct from this, but no reference is made to Aristida. According to her figures the lemma is much shorter than the glumes; the column is straight with regard to the lemma in one figure, bent both from the body of the lemma and from the awn in another figure. It is difficult to know from the figures whether the lemma is furrowed or not though a furrowed condition is suggested. The dimensions of the figures are : Glumes 71 and 63 mm. ; body of lemma 42 and 46 mm. ; column 27 mm. ; awn 70 mm. The magnification of the figures is said to be 3. 7. Henrard, in Meded. Rijks Herb. Leiden liv.B (1928) and ]viiL (1929), follows Domin in referring the species to Aristida . He did not see the specimens and his information seems to have come from a sketch and other data sent by A. B. Rendle. From his figure, key and description we get the following data: Glumes 11-13 mm. long, subequal or the lower slightly the longer, the lower 3-nerved, the upper 1 -nerved; lemma terete, tubulous, up to 14 mm. long* column not bent from the body of the lemma, straight* strongly twisted, ,> about 7 mm. long; awn slightly curved, up to 16 mm. long, not bent from the column. 8. The specimens were actually seen by Brown, Bentham, Domin* and Hughes, but the accounts of these authors are not in complete agreement. Brown gives no dimensions. Bentham gives the length of the glumes as 4 to 5 lines, which is rather shorter than Domin ’s 11-13 mm., but Bentham may have deliberately excluded the awnlets. The magnification of Hughes’s figures is said to be 3; if the magnification is really 5 the dimensions agree with those given by Domin and Henrard. Mrs. Chase now writes me that there is a tracing of Miss Hughes’s original drawings in the United States National Herbarium ; they are of the same size as the published figures and are marked by Miss Hughes “5X’?- Also Henrard calls the lemma “ terete, tubulous,” which with him1 usually means that the margins of the lemma are convolute, but Brown states quite clearly that the margins are involute. 9. Henrard, in discussing Aristida sect. S Hreptachne (R.Br.) Domin, states that 4 ‘if in Aristida utilis, a species with distinct but thin lateral awns, those lateral awns disappear* we have (as to the spikelets) before us the Streptachne stipoides of R. Brown.” 10. Aristida utilis F.M.Bail. in Queensl. Agric. Journ. xviii. 340 (1907) was described from specimens collected by Mark Webb near Cooktown, the type-locality of Strepiachne stipoides. The type consists of old specimens, of which the lemmas have prominent lateral awns 4-6 mm. long. 11. In more recent years an excellent series of specimens of Aristida utilis has been collected and a special study made of the large number of specimens constituting Blake 8149 and 13459. (See plate I, drawn from 8149; figs. 2-12 were drawn from spikelets from one and the same specimen). STREPTACHNE R. BROWN AND PHEIDOCHLOA GENUS NOVUM, ETC. 13 These specimens show : (a) Glumes equal or more or less unequal, in the latter ease either the upper or the lower glume the longer; all varia- tions to be seen in one and the same panicle; the length varies from 9 to 12 mm. in 8149, and 9 to 13-5 mm. in 13459. (5) Lemma, column and awn nearly in a straight line (in immature spikelets) to variously bent and geniculate with respect to one another; lemma shorter than or as long as the glumes; awn straight or gently curved; the lemma varies in length from 6-5 to 13 mm. (usually) ; the column is 4*5-7 mm. long; the (central) awn varies from 9 to 15 mm. long. (c) The lateral awns vary greatly; when well-developed up to 4 mm. long, very often greatly reduced or one or both entirely wanting. Figs. 9-12 of the plate illustrate stages in the reduction of the lateral awns in different spikelets from a single specimen; fig. 12 is that described for Streptachne stipoides R.Br., while fig. 9 represents the state found in the type of Aristida utilis F.M.Bail. 12. In one and the same panicle of many specimens of particularly Blake 8149 and 13459 occur spikelets which match those of the type-specimen of Aristida utilis (figs. 2 and 9) and other spikelets agreeing with all the available data concerning the type of Streptachne stipoides (figs. 3 and 12). From the above data there seems no doubt whatsoever that Aristida utilis F.M.Bail. and' Streptachne stipoides R.Br. are conspecific. In general the longer the panicle the greater the tendency to produce prominently 3-awned lemmas, and the smaller the panicle the greater the tendency for the greater number of spikelets to have the lateral awns much reduced or absent. As a rule the panicle is about as long as the remainder of the culm. It is noteworthy that the panicles of the type -of Streptachne are according to Bentham 5-6 in. long* while the usual length in A. utilis is at least twice this. Banks and Solander were at Endeavour River between June 17tli and August 5th, 1770, an unfavourable time of the year for collecting grasses in this region. I visited the area at the same season (July 30th to August 2nd) in 1943 and found Aristida utilis very abundant, but the plants had shed nearly all their florets. A search for plants without lateral awns was undertaken, and it was evident that a considerable variation occurred. Only a very few specimens in over-mature condition or with spikelets arrested in development were procurable, and though some spikelets have very tiny lateral awns there are none with them entirely absent. The type-specimens of A. utilis from the same locality were also collected rather late in the season (May). So it is possible that none of these specimens gives a true idea of the species. The generic position of the species has now to be considered. Hughes, l.c., has given sufficient reason for not uniting Streptachne with Stipa; the absence of an articulation between awn and lemma is exclusive, besides the frequent presence of lateral awns, which was * Mrs. Chase writes me that in the United States National Herbarium there is a tracing of these plants sent by Miss Hughes, and the panicles measure 23 and 24 cm. long, the two lower branches of each 6-5 and 7 cm. long. 14 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. unknown to her. As Domin, l.c., has pointed out, it is not possible to separate Streptachne from Aristida on the character of the reduced lateral awns, as there is a complete series of species in which the lateral awns are more and more reduced until they completely disappear. He reduces Streptachne to a section of Apistida. Henrard, op. cit. lviii. 142, discusses the question again and after mentioning some American species of Aristida referred to Streptachne by Humbold, Bonpland and Kunth, states “If we compare these species with the genus, described by Brown, it is impossible to find differences in the spikelet-characters and we can find transitions between plants with short lateral awns and others where the lateral awns are quite obsolete and absent”; on p. 143 he goes on “The section Streptachne is not a very natural one and it is impossible to limit it sharply. It is probably better to unite Streptachne and Ghaetaria, but for practical reasons I have separated them in this work. ’ 9 To the above observations it may be added that the general appear- ance of the species is that of Aristida (as was noted by Brown), the appearance, texture and nervature of the glumes and lemmas are quite those of this genus, as is also the structure of the awns. The small palea and furrowed grain are likewise found in undoubted species of Aristida. The column is frequently bent away from the lower part of the lemma, and this feature appears not to be found in other sections of the genus, but it is not constant even in the type of Streptachne stipoides. The column of this species is a prolongation of the lemma proper, with 3 nerves running one into each awn. There are undoubted species of Aristida in Queensland with such a column between the body of the lemma and the awns, but all have unfurrowed lemmas with convolute margins; they are A. psammophila Henr., A. macroclada Henr., A. Schultzn Mez, A. Warburgii Mez, A. intricata S. T. Blake, A. latifolia Domin, A. holathera Domin and A. pernicio&a Domin. Of these A. perniciosa rather closely resembles Aristida utilis in foliage, in the elongated trailing uppermost internode, structure of the panicle, and in the texture, nervature and more or less in the shape of the glumes; the lateral awns, too, are decidedly shorter than the central awn. The points of resemblance to Aristida are so many and so important, while the two points of difference — the reduced lateral awns and the oblique column — are so inconstant in expression, that there seems no doubt that Domin and Henrard are right in treating Streptachne stipoides R.Br. as a species of Aristida. Since Sireptachne stipoides R.Br. and Aristida utilis F.M.Bail. are to be regarded as conspeeific, the following data must be considered before it is possible to decide the legitimate name of the species under Aristida : 1. When Streptachne stipoides is transferred to Aristida the epithet stipoides becomes illegitimate in the new position owing to the earlier homonyms Aristida stipoides Lam. Tab. Encycl. & Meth. 157 (1791) and A. stipoides R.Br. Prodr. 174 (1810). 2. F. Mueller, in Journ. & Proc. Roy. Soc. N.S. Wales xv. 237 (1882) cites Streptachne R.Br. as a synonym of Stipa L. but without remark and without transferring any species. STREPTACHNE R. BROWN AND PHE1DOCHLOA GENUS NOVUM, ETC. 15 3. F. Mueller in First Census 133 (1882) has the following entry under Stipa : S. Streptachne, F.v.M. in journ. R..S. of N.S.W. 237 (1881) .... Q.— B.fl. VII, 572, 4. Domin, in Biblioth. Bot. xx. heft 85, 342 (1915) transfers the species to Aristida as A. streptachne n. nom. citing Streptachne stipoides R.Br. Prodr. 174 (1810) and Stipa Streptachne F.Muell. in Journ. & Proc. Roy Soc. N.S. Wales xiv. 237 (1881)*; First Census 133 (1882) .... etc. 5. Mueller’s reference in the First Census to Journ. & Proc. N.S. Wales xv. has no nomenclatural significance, for there is no reference, expressed or implied, to the combination Stipa Streptachne nor to the species Streptachne stipoides. The formula “Q. B.fl. VII, 572” in the First Census means that the species mentioned occurs in Queensland and was described in Bentham’s Flora Australiensis vii. 572. The only Queensland plant described by Bentham on this page is Streptachne stipoides R.Br. where a reference is given to R.Br. Prodr. 174 f. According to some recent interpreta- tions of Art. 37 of the International Rules by Airy-Shaw (Kew Bull. 1938, p. 256) and Sprague (Kew Bull. 1939, pp. 322-3) Mueller’s formula must be regarded as an indirect reference to Streptachne stipoides R.Br. Prodr. 174, and this would validate the publication of the combination Stipa Streptachne F.Muell. 6. Though Stipa\ Streptachne F.Muell. is a valid combination, it is illegitimate, since the epithet stipoides should have been used, this having priority (as an epithet in the required position) and had not previously been used under Stipa (Art. 54). 7. According to Art. 60, the publication of an epithet in an illegitimate combination must not be taken into consideration for purposes of priority. 8. According to Art. 69, Domin was at liberty to use the epithet Streptachne when transferring the species to Aristida (since the epithet stipoides under Aristida would produce an illegitimate combination, namely a later homonym) though he was not obliged to do so, hut the combination Aristida streptachne then has to be treated as a new name (as was done by Domin), not as a new combination (as was done by Henrard), so that the date of the epithet would date from the combination under Aristida , namely 1915. 9. The epithet in Aristida utilis dates from the date of publica- tion of this combination, namely 1907. 10. So long as Streptachne sJtipoides and Aristida ntiUs are considered conspecific, Aristida utilis must be accepted as the legitimate name of the species. * This volume is xv., the journal for the year 1881, published in 1882, so that Mueller’s citation of merely the year 1881 is misleading; Domin added the number of the volume published in 1881, apparently without checking the reference. t Miss J. W. Vickery drew my attention to this nomenclatural significance of Mueller’s formula. 16 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND.

Under the original description Bailey states that “the long smooth peduncles are being used in the manufacture of hats’ ’ but the grass is no longer being thus utilised. In Compreh. Catal. 622, Bailey gives “hat grass” as a vernacular name. No information is available as to its value for grazing, but it appears to be but little eaten, and grows only on poor country. A. spuria Domin, l.c., 341 (1915), Henr. op. cit. liv.B 585 (1928) and lviii. 149-50, t.58 (1929) is a species very closely allied to A. utilis show- ing a parallel degree of reduction of the lateral awns. It differs from A. utilis by having glabrous intemodes, fine convolute-setaceous leaves, shorter and more or less erect uppermost internodes, usually shorter panicle-branches and rather smaller glumes with shorter awnlets. On the average the glumes are 6-8 mm. long, sub equal or one or the other very slightly the longer, with awnlets of up to 1 mm., the lower gradually very acute, the upper acute but somewhat contracted below the awnlet, the lower prominently 3- or 5-nerved and scabrous on the nerves, the upper 1 -nerved somewhat scabrous on the nerve ; the lemma is furrowed with involute margins, usually 8-10 mm. long, rarely slightly longer or shorter ; the column is mostly 5-7 mm. long, rarely so short as 4 mm. ; 18 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. the central awn is usually 9-13 mm. long, rarely so short as 7 ; the lateral awns are up to 4 mm. long, but are frequently very much smaller or insignificant to absent. The type-specimens were collected by Domin on Castle Hill, Townsville, in February, 1910, but appear to have been seen by no other botanist. Henrard has taken White 1614 from the same locality as belonging to Domin ’s species; Blake 8349, also from the same locality, agrees. Domin describes the length of the spikelet-parts as follows: glumes 6-8 mm. ; lemma with callus 6*5-7 mm. ; column about 3*5 to nearly 4 mm. ; central awn about 7-9*5 mm. ; lateral awns up to 2 mm. Domin also describes his plants as annual, with the habit of A. arenaria Gaud. I think that there is no doubt that Henrard is correct in his interpretation of Domin ’s species, but it would appear that Domin had young plants with apparently smaller spikelets than usual, or perhaps they were not quite mature. I have found spikelets with the dimensions given by Domin, but the great majority have longer lemmas and awns, with the dimensions given above. The plants are perennial, frequently with branched culms. The following collections are represented in the Queensland Herbarium : — Queensland. — Burke District : Near source of Poison Creek, about 90 miles N. of Hughenden, in Eucalyptus (box) forest on stony ground, ca. 2750 ft., April 12th, 1935, Blake 8608.

Edwards, on cliffs above the northern side of the gorge, April 1st, 1934, Everist 609. The other species which have been referred to Streptachne have been discussed by Hughes, l.c., p. 303. To these remarks it should be added that S. ramosissima (Trin.)Trin. and S. verticillata (Nees)Trin. & Rupr. rightly belong to the genus Stipa as was pointed out by Henrard, op. cit. lviii. 142, and not to Muelilenbergia as indicated by Hughes, l.c., nor to Dichelachne as earlier suggested by Hughes, op. cit. 1921, 28 (1921). Of the American species, I have seen specimens of Aristida ternipes Cav. ( Streptachne scabra H.B.K., S. tenuis H.B.K.), A. jorullensis Kunth ( Streptachne pilosa H.B.K.) and the comparable A. Orcuttiana Yasey. These represent an evolutionary trend of reduc- tion from characteristic species of Aristida sect. Chaetaria parallel to what has taken place in the Australian group. The groups from the two continents are not particularly closely allied, and, for that matter, A. Orcuttiama appears not to be very closely allied to the other two American species. Streptachne indica Buese ex De Yriese, PI. Ind. Bat. Or. 99 (1856), Miq. FI. Ind. Bat. iii. 751 (1859), from Java, was not mentioned by Domin, Hughes or Henrard, and I have found no further clue to its STREPTACHNE R. BROWN AND PHEIDOCHLOA GENUS NOVUM, ETC. 19 identity. The characters given (taken from Miquel, l.c., apparently a copy of the original description) of “nodis pilosis/’ “spiculae basi fasciculo piiorum orevium cinctae, ” “valvula inferior glumis paullo brevior leviter bidentata et in aristam scabram .... terminata,” suggest a relationship remote from the species discussed above, and in the absence of the type-specimens it is useless to guess at what it might be. There is no mention of it in Koorders’ Exkursionsflora von Java (1912). Four points arise from the inquiry into the nomenclature of & Ureptachne stipoides under Aristida. 1. It does seem unfortunate that illegitimate though valid names are excluded from considerations of priority. A more logically practical method of dealing with matters of priority would seem to be along the lines suggested by Furtado (particularly in Gardens’ Bull., Straits Settlements, xi. 1-30: 1939), according to which names are classified according to validity, priorability and legitimacy. Validly published names may be priorable whether they are legitimate or not, and on transfer to another genus the oldest valid epithet priorable in the new position must be employed and such a transfer becomes a new combination. If such a procedure were incorporated in the Inter- national Rules, Stipa Streptachne would be a priorable name, although illegitimate and its epithet would have to be taken into consideration when the species is transferred to Aristida. It would be then compul- sory to use this epithet (dating from 1882) and the resulting new combination A. Streptachne (F.Muell.) Domin would be the legitimate name for the species. 2. Art. 44 states that 4 ‘The name of a species .... is not validly published unless it is accompanied (1) by a description of the group, or (2) by the citation of a previously and effectively published description of the group under another name, or (3) by a plate or figure with analyses showing essential characters; .... ” The publication of the name of the species Streptachne stipoides does not conform to any of these conditions, for, as previously stated, (p. 11), the name is merely listed after the description of the genus. Yet the publication is quite unequivocal, is far more satisfying than many a “citation of a previously and effectively published description” and nobody seems ever to have questioned the validity of this form of publication. Art. 5 — “In the absence of a relevant rule .... estab- lished custom must be followed” — can be invoked, but surely such a case should be definitely covered by the Rules. 3. In the Rules, no limits are set as to the interpretation of a “citation of a previously and effectively published description/’ In the case of Stipa Streptachne F.Muell., validity is allowed merely because no other Queensland plant happens to be described on the cited page of the Flora Australiensis. Can a reference be valid if no name of a taxonomic group is cited ? or again if there is no reference to the original description of a group ? 4. Should validity be denied to the combination Stipa Streptachne F.Muell. in First Census, 133, on the grounds of absence of description and imperfect reference, attention must be paid to F. M.

There is no other reference. According D 20 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. to the letter of Art. 44, the provision of this description would validate the publication of the name Stipa Streptaclme, but the position then arises that the publication of a name can be validated by reason of author having published a “ description” of a species of which he had seen no specimen.

Queensland. — Cook District : About 40 miles N.W. of Mungana, in Melaleuca forest on fine whitish sand, abundant, April 8th, 1938, Blake 13732 (type) ; N. of Chillagoe, near Walsh R, in dwarf Mdaleuca forest on sand, ca. 1000 ft., April 2nd, 1938, Blake 13592. A delicate annual grass (plate II) with filiform culms, short setaceous leaves and long-exserted inflorescences of few, 2-flowered spikelets with long purple awns. Most culms bear a short floriferous branch from the penultimate node (topmost but one) ; the intemode above (penultimate internode) is much shorter than those immediately below, often the shortest on the culm, and this feature gives a peculiar facies to the plant. Occasionally a branch is also borne at the ante- penultimate node, and in this case the antepenultimate internode is rather shorter than the one immediately below, though much longer than the penultimate. The inflorescence, when consisting of up to 4 spikelets, is a raceme, but when 5 or 6 spikelets are present the lower one or two branches bear a shortly pedicellate lateral spikelet, so that a depauperate panicle is the result. On account of the 2-flowered spikelets and the lemmas with a single terminal bristle-like awn this new genus is most closely allied to Eriachne R.Br., but the extraordinarily elongated upper glume (twice as long as the lower), the subterete florets deeply furrowed in front and with a pungent slender callus, the prominently inrolled (not merely incurved) margins of the lemma, the elevated keels of the palea and the peculiar very narrow grain are all quite distinctive features. The grain of Eriachne , so far as has been ascertained, is more or less obovate in outline and flat or nearly so on the anterior face. In E. meUcacea F.Muell. the grain appears to be constantly concave along the anterior face, but it is very different from that of Pheidochloa which has the margins incurved leaving a very deep furrow and giving a crescentic- reniform appearance in transverse section. The lodicules are extremely fine and delicate. The anthers are extraordinarily small and are always to be found tangled up with the stigmatic hairs in mature spikelets; the spikelets are very evidently cleistogamous. Small anthers associated with cleistogamy have been found in Eriachne triseta Nees, E. Armitii F.Muell. ex Benth., and E. stipavea F.Muell. var. hirsuta Hartley. Most species of this genus have relatively large anthers which are laterally exserted during anthesis ; they are usually 3 in number, though 2 only in some of the small species such as E. ciliata R.Br. and E. fili- fonnis Hartley. Vegetatively Pheidochloa differs from Eriachne (except E. Dominii Hartley) in the very short penultimate internode of the culm and in that the leaf-blade is decidedly narrowed to the base from shortly above, but this latter character is not readily discernible unless the leaf-blade is artificially unrolled and flattened out. The position of the genus in the family is not clear, though Eriachne has usually been placed in the Aveneae. C. E. Hubbard (Hook Ic. PI. 22 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. under t.3418: 1940) has pointed out that the Aveneae may be divided into two groups distinguished partly on the nature of the awn. In the typical group ( Aveneae subtribe Euaveneae Beck) the awn is dorsal and its column often subterete, or at least not flattened or laterally winged. The column is formed by the continuation of the middle nerve and not by the splitting of the lemma into three segments. On the other hand, in the second group ( Aveneae subtribe Danthomeae Beck), the lemmas are usually two-lobed, and the awn when present arises in the sinus of the lobe. Here the column of the awn is flattened and its formation is due to the gradual splitting of the apex of the lemma into three segments. Eriachne and Pheidochloa differ from each of these groups, for in these genera the awn is a continuation of the fusion of all the nerves of the unlobed lemma, and perhaps they are as well placed in the Festuceae. The name Pheidochloa is derived from eiSos“, sparing, thrifty; and yAoa grass. It refers to the scanty inflorescence, 2-flowered spikelets, the two minute anthers and the very fine and thin lodieules. Both collections are from similar types of country — ill-drained sandy land supporting an open dwarf -tree community of Melaleuca spp. associated with chiefly small annual grasses and Cyperaceae belonging to the genera Eriachne, Ectrosia, Heterachne, Schdzach yri u m, Thaumastochloa and Fimbristylis.

Locality: Triassic of Mt. Crosby, S. Queensland. Collected by F. A. Perkins. I The hindwing resembles the forewing in a similar manner and to about the same degree as does the fore and hindwing in any primitive Mecopteroid insect of comparable size. The formal description of the species is to be regarded as based on the type forewing. The hindwing which has been associated with it, as a paratype, was found separately; therefore there is no direct proof that it actually belongs to the same species. However the two specimens are so closely comparable that in any living species of primitive Lepidoptera, for example, it would be difficult not to regard them as fore and hindwing of one species, or at least as belonging to closely allied members of the same genus. R4 near apex is sinuate as though there was a pterostigmatic area on the costal margin at its apex, but no special texture of the wing surface can be detected in this region, so that this feature must be regarded at most as indicating what might be a relict feature. Theoretical Discussion. The position of this fossil in the classification of insects may be of considerable theoretical importance, since it seems possible that it is one of the earliest known relatives of the Lepidoptera, an order con- cerning whose early geological history in Mesozoic times, nothing is known. Its discovery will therefore arouse new interest in the possible origins of the Lepidoptera. 'FMASSie INSECTS OF QUEENSLAND. 41 On general grounds it has long been considered that the members of the suborder Homoneura are the oldest living types of Lepidoptera and that some living species retain primitive features which place them close to the prototype of that order of insects. Indeed, from a study of all the living forms a hypothetical archetype of the order has been conceived as appearing very much like some primitive living members of the Hepialidae, one of the largest families of the Homoneura. How- ever, up till now no true member of the Lepidoptera has been discovered in any geological horizon lower than the Tertiary. The hitherto oldest known fossils which are without doubt Homoneurous Lepidoptera, belong to the family Micropterygidae, the oldest actual species being Micropteryx proaviteUa Rebel which was obtained from Baltic amber of Oligocene Age. Another similar species Micropteryx pervetus Cockerell has been found; in Miocene amber from Burma. M. proavitella differs only in minor generic details from living members of its family and furnishes no novel clues as to the origins of the Lepidoptera. Further it was found in association with more special- ised forms closely related to living genera and species of advanced families of Lepidoptera. It is evident that the origins of the Lepidoptera must be sought in earlier geological ages. Some poorly preserved insect impressions from the Jurassic were formerly thought, by Handlirsch, to have belonged to the Lepidoptera but were afterwards proved to be unquestionably the remains of Homo- ptera allied to some primitive living forms of cicada, so that although a possible Jurassic origin for the Lepidoptera was formerly postulated it had no basis in known facts. There was only indirect deduction upon which to base any assumption that the Lepidoptera was Mesozoic in origin, although on general grounds it was thought that their evolution must have taken place concurrently with the rise of flowering plants in Mesozoic times. However, as we know from the previous work of many students, including Handlirsch, Tillyard, Carpenter and other workers, that all the other principal stems of the Mecopteroid complex of orders were already well defined by early Mesozoic times, the appear- ance of a primitive member of the Lepidoptera in late Triassic beds would neither be a matter of great surprise nor greatly inconsistent with modern trends of knowledge and theory. In fact the entire absence of the Lepidoptera from the Mesozoic period would be surprising on any grounds, other than that of the difficulty of finding the rare beds in which such delicate insects could be preserved. The question naturally arises whether, in view of the trend of this introduction, Eoses is possibly to be regarded as a primitive Lepidop- teron? Accepting for the moment that the fore and hind wings do belong together, it is abundantly clear that if these wings were those of Lepidoptera the species would fall much closer to the suborder Homoneura than to the Heteroneura, the other large division of the order Lepidoptera. The most striking distinction between these two great suborders is the possession by the Homoneura of five radial veins in 42 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. both wings whereas in Heteroneura although 5 radial veins are present in the fore wing, only two occur in the hind wing. Of the families of the Homoneura, so far as may be judged by wing venation alone, Eases would fall perhaps closer to the Hepialidae than to any other. In many particulars it is closely similar. However, one striking character at once separates Eoses from all previously known families of the Homo- neura and indeed from all living Lepidoptera, This outstanding feature is present in the median veins of both wings. Whereas in all living Lepidoptera M2 is a simple vein, in Eases M2 is bifurcate. In any dis- cussion therefore on this fossil, the study of M2 is of prime importance. Another important character is the separation of M4 and Cuia before the margin. This also is a distinctive feature, but in as much as this has been found as an occasional aberration in individual specimens of more than one species of the Hepialidae, e.g., Trictena argent at a and Sthenopis, its presence in a supposed ancestral form of the Hepialidae would not be a surprising occurrence. In other venational particulars, so far as they are preserved in the examples available, there can be no strong objection to Eases being placed as a member of the Lepidoptera or even in a position on the ancestral line leading to the Homoneura and the family Hepialidae. The seemingly critical character upon which the classification of Eoses should rest is shown to be the presence of both M2a and M2b> a double feature found in none of the living forms of Lepidoptera. Study of late Palaeozoic members of the Mecopteroid complex shows that M2 is bifurcate in several forms. Permachorista, a genus of the order Mecoptera of the Upper Permian of Belmont has this feature well defined, and it survives in Jurassic members of the order. According to the views of Tillyard, the Upper Permian genus Belmontia placed in the order Paramecoptera is the oldest recognisable form related to the ancestor of the Lepidoptera. The Paramecoptera are a Permian derivative of the Mecoptera and alongside many primitive features have developed some specialised characters. Tillyard considered that the three great orders Trichoptera, Lepidoptera and Diptera arose from the Paramecoptera in the Triassic or Lias. While Belmontia does present many primitive features it cannot be considered directly ancestral to Eoses , for M2 is already simple in Belmontia. The common ancestor of Eoses and Belmontia must be sought rather in those members of the Permian Mecoptera in which this vein had not already undergone reduction to the simple condition. Eases thus possesses an archaic venational character which separates it defin- itely from Belmontia and links it with the Permian members of the order Mecoptera. The possible conclusion is reached that Eoses may be a Triassic development of and lineally descended from one of the Permian branches of the Mecoptera. It is probably not directly related to TRIASSIC INSECTS OF QUEENSLAND. 43 Belmontia, although this fossil stands on a side branch not very far removed from the main stem. It seems then that the discovery of Eoses again draws attention to the fundamental relationship between the ancestral Mecoptera and the Trichoptera and Lepidoptera, a relation- ship which tended to be overlooked after the discovery of Belmontia. Detailed comparisons between Permochorista and Eoses indeed show that however much the form of the wings and the general appear- ance may differ, there are basic features in common extending even to the possible relict character of a pterostigmatic area on the costal margin, and it seems an irresistible conclusion that Eoses and Permochorista are fundamentally related, and that this relationship exists because they had common ancestors in Permian times. The tentative conclusion is reached therefore that Eoses is a primi- tive Lepidopteron, representing a stock which had its origin in a branch of the order Mecoptera, from which it parted company at the end of the Palaeozoic or in the early Mesozoic. Having been so bold as to see in Eoses an early member of the Lepidoptera and therefore the first known Mesozoic member of the order, the writer is tempted to determine a tentative classification into which it may be placed. Eoses may be conceived to be related to, and to fall in the same suborder as, the ancestor of both the Homoneura and the Heteroneura. As both Comstock and Tillyard have shown, any attempt to construct an archetype for the Heteroneura leads inevitably to an ancestral Homoneurous type, and this archetype, as deduced even in the absence of any leads from fossil evidence, differed significantly from Eoses principally in the character of the bifurcate M2. For convenience it may be useful to regard this archetypic concept in so far as it is represented by Eoses as constituting a suborder Eoneura of the Lepidoptera, equal in classificatory value with the Homoneura and the Heteroneura. Both the Homoneura and Heteroneura may have been formerly derived from the Eoneura. This new classificatory concept must be viewed in very broad detail, and it is as well to remember that Eoses itself may not be a direct lineal ancestor of the later Lepidoptera, rather but one representative of a whole range of early Lepidoptera of the Eoneura, from one of which later Lepidoptera may have been derived by reduction and specialisation of the characters which we see in the Eoneura. In so far as both Homoneura and Heteroneura differ from the Eoneura in the absence of the bifurcate M2 it may be that they are both to be derived together from a member of the Eoneura in which this reduction had already taken place. A tentative classification could be arranged as follows: — Order Lepidoptera. 1. Suborder Eoneura. (a) Family Eosetidae. 44 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. 2. Suborder Homoneura. (a) Family Micropterygidae. (b) Family Hepialidae. 3. Suborder Heteroneura. ( a ) Family Cossidae. (b) Family Castniidae, etc. The interrelations of these suborders and the ancestral connections of the Lepidoptera cannot of course be shown adequately by a mere list and the following diagram may give a more convincing if still very sketchy conception of the main relationships : Belmontia preserves a record of one of the evolutionary trends of Mecopteroid ancestors in late Palaeozoic times, but it is seemingly merely a Permian specialisation away from the main Mecopteroid stem. It thus loses its high place as a supposedly direct ancestor to the Lepidop- tera and Trichoptera and falls into an evolutionary backwater without recognised descendants in the Mesozoic. Like the Trichoptera, the Lepidoptera seem to have originated as closely allied specialisations from an ancestral Permian branch of the Mecoptera. Eoses preserves a Triassic phase of this evolution. The trends of development even in the Lepidoptera Eoneura were towards reduction of the cross-vein systems, reduction of terminal branching of the veins and partial coalescing of the apical portions of Cuia and M4. This trend towards reduction has continued until Tertiary times. All the main evolutionary trends in venation are expressed in modern families by various degrees of simplification and reduction from the ancestral Eoneurous pattern. TRIASSIC INSECTS OF QUEENSLAND. 45 SUMMARY. Eoses trimsica a member of the order Lepidoptera, falling into a new suborder, the Eoneura is described from the Triassic Beds of Mt. Crosby, South Queensland. There is a theoretical discussion on the significance of this discovery of the first supposed Mesozoic member of the Lepidoptera. Postscript : Washington, D.C., 10 th October, 1944. In the United States National Museum collection there is a male specimen of llcpialus seguoiolus Behrens, from Mendocino, California, which has both M,a and M2b iiresent in the forewings, as in the fossil Eoses.. Bight and left fore- wings both have this feature which, so far as known, is unique among living Lepidoptera. The liindwings are normal. Text-fig. 3 gives a representation of the venation of this interesting specimen. Text Fig. 3. Venation of aberrant male of Hcpialus sequoiolus Behrens, from Mendocino, California. No other specimen of this species among ten others in the collection has been discovered to possess this aberrant condition, nevertheless the appearance of a bifurcate M2, even as an occasional atavistic survival in a living member of the Hepalidae, may be considered to furnish some small measure of proof that the ancestor of the Lepidoptera Honroneura may once have possessed this character as a normal feature of its venation. The discovery may be held to strengthen a little the view that Eoses is an early Lepidopteron allied to the main stem from which the Homoneura have evolved.

Usually an areole is present in the forewing and a median cell in both wings, but there are some exceptions. The median vein is present in the lepidopterous cell, and usually divides there into its two primary branches, but one of these may be absent. The second cubital vein is present in both wings. The anal vein in the fore wing is forked at its base. In the hindwing there are three anal veins. The larvae are wood-borers. The Cossidae, as is shown by their neuration, are the most primitive family of the Lepidoptera Heteroneura. In the Transactions of the Entomological Society of London for 1918 I gave a general review of the family based on the world-fauna, and to this I would refer the reader who is interested in its phylogeny. The family is present in all temperate and tropical regions, but is more numerous in species in Australia than in any other continent. For these two reasons their study is of special interest. Owing to their cryptic coloration and habit of concealment little was known of our Australian species until recently. Only a few were named by early writers. It was not until the study of the habits and the breeding of the larvae were undertaken, that adequate material for description was available. For this we are indebted particularly to two collectors, the late Mr. F. P. Dodd and the late Mr. W. B. Barnard. An interesting account of the methods of the former is contained in Oberthur’s Etudes de Lepidopterologie Comparee xi. (1915). All the Australian species and, with the exception of Xyleutes, Zeuzera and Dudgeonea, all the genera are endemic. Key to Genera. 1. Forewings without areole Forewings with areole 2.

This large genus is found in the Indomalayan, African, and Neotropical regions, but the species are more numerous in Australia than elsewhere. Their discrimination is difficult, for they often show varietal differences, especially in the development of the markings of the forewings. Sexual differences are not uncommon, and the range of size in any species may be large. For their identification careful and detailed descriptions are necessary, and these must be carefully studied. No help would be given by the construction of a key, such as is useful in many other cases. 4. Xyleutes zophospila n.sp. £ o(/)og7t iAo?, dark-spotted.

I have now examined a long series of this species, and my former description needs amplifying. The antennal stalk is white in the male and usually in the female also. The thorax has anterior and posterior lines of hairs, which may be orange-ochreous, fuscous-grey, or ochreous- grey. Similarly the abdominal tuft varies in colour. The white markings of forewings vary considerably in shape and size. Queensland: Injune; Carnarvon Rge.; Stanthorpe. New South Wales: Tyringham. 6. Xyleutes tigrina H-Sch. Ausser.

By Frederick Bennett, B.Sc. (With one map in the text.) (Received 24 th April , 1944; accepted for publication 31 st July , 1944; issued separately, 25 th June, 1945.) INTRODUCTION. This paper deals with the middle and lower portions of the Pioneer River basin below Nicholson’s Crossing (Parish Abingdon, por. 1302) and areas adjacent to this part of the basin — and broadly includes the parishes of Hamilton, Ossa, Hampden, Bassett, Abingdon, Greenmount ■and Howard, all of which are subdivisions of the County of Carlisle. PHYSIOGRAPHY. The River basin is in thej lower part determined chiefly by (1) The Northern Divide running S.E. from Mt. Dalyrmple to Kungurri then S. of Mt. Martin through Mt. Toby to Mt. McGregor, then turning E. by Mt. de Moleyns to The Leap, through Farleigh and the Black Mountain thence to Glenalbyn, Glenella through portion 95, parish Bassett past the head of Thornber Creek to Slade Point where it reaches the sea — then, presumably, under the sea, to Brampton Island. (2) On the west a granitic scarp from Mt. Dalyrmple S.E. to Dun wold (where a lower part to the S. lets Cattle Creek through) then by the Mia Mia Ranges S. as far as the west of por. 133, parish Mia Mia (where it joins a spur from the Clarke Range south of Boongana). (3) An eastern boundary coming up from Connor’s Range on the S. through Mt. Bridgman, Mt. McBryde, Ben Mohr and Blue Mountain. A low exit point exists round Mirani; Mt. McGregor lies N.N.E., the Blue Mountain is S.E. and the Mia Mia Range lies S.W. The determining slopes are two — a slope S.E. towards the coast between Dundulu and McE wen’s Beach — the other, the steeper of the two, due E. towards Mt. Bassett. The river therefore runs due E. from Mirani falling 171 feet in 25 miles and in consequence of this big fall there are few really big pools. The river is rapid, and, running near the base of the igneous north scarp for 25 miles, has a rocky bed as far as Dumbleton; it is only at Foulden that tidal influences come into play. L 72 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. 1 Map of the Pioneer Ifover Basin, GEOLOGICAL NOTES ON THE PIONEER RIVER BASIN. 73 The S.E. fall, however, has a noteworthy effect. The Pioneer here receives many streams from the main scarp — the N. boundary — but not one from the South or East. The north branch of Sandy Creek, and Baker’s Creek draw water from within a stone’s throw of the very river bank and three sugar mills have happily utilised this peculiarity to dispose of their effluents without contaminating their water supply. The creeks themselves show the same peculiarity. Rocky Creek draws water from por. 104, Par. Greenmount, on the very brink of Baker’s Creek. GENERAL GEOLOGY. The sediments of the area under discussion belong to the Bowen Series, but igneous 'activity subsequent to their deposition has been so intense as to obscure all but small patches of this series, this igneous activity producing first an extensive series of diorites and later rhyolites, the two types covering the greater part of the area and obscuring the underlying rocks. In addition to these two main types, others with their hypabyssal equivalents occur in the area. As is well known, with a geological survey of this kind which involves igneous rocks an intensive survey of an area is required in order to produce a connected picture of the distribution of the various igneous types, but as this is in the nature of a reconnaissance survey it has been thought advisable to record localities of types rather than construct a pretty picture based on insufficient data, and it is to this end that the following types and their localities are discussed. Diorites. The diorites with, in places, andesitic tuffs form the largest and most marked part of the area. From Black Mountain, which dominates this igneous mass, outcrops of diorite radiate in every direction — to Seaview, Green Island, Habana, Eimeo, Black’s Beach, Slade Pt., Glenella, Mt. Oscar, Mt. Bassett, and as far as Brampton Islands. In addition to this large single area, diorite masses separate Goose- pond Creek from McCready’s Creek on the one hand and Fursden Creek on the other; Fursden Creek from the east branch of Nebia Creek and also the eastern and western branches of Nebia Creek. The interesting mass of Turner’s Sugarloaf (N.W. of por. 499, Par. Bassett), which is weathered felsitic material (probably a dyke), is surrounded by masses of diorite which occur on the hill to the S.E.f and four smaller spurs to the S.W. Two branches to the north are dioritic ; the more western of these drops considerably to form two yet smaller ridges at the head of Reliance Creek. 74 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. A dioritic mass occurs in the form of an inlier jutting up through the surrounding rhyolite in por. 757, parish of Hampden; relics of its former rhyolite cap form a scree on the lower flanks of its N.E. side. Other inliers of this nature, in each case surrounded by rhyolite, occurs at Dalrymple’s Lookout (this should not be confused with Mt. Dalrymple which is many miles from this point) and at portion 648 and section 60, both in the parish of Hampden. Quartz diorites occur at Dalrymple’s Lookout, portion 11, Green- mount, also at portion 661, parish Abingdon, and the E. side of Antoney’s Crossing, S.W. 'of portion 534, parish Abingdon. These also occur at Homebush Lookout, portion 441, parish Eton, Burgess’ Quarry, portion 1464, parish Abingdon, White’s Ridge, portion 1088, parish Abingdon, and (probably) Hogan’s Ridge, portion 1302, parish Abingdon; also the Quarry at Newbury Junction. Basic Tuffs. An area from portion 1547, parish Mia Mia, past portion 989, parish Hamilton (in the river bed near H. Rowe’s), at McGregor Creek Bridge, Toby Creek Bridge, The Dingle (E. of Marian), Reeves Creek Bridge, portion 1274 parish Hampden and the mouth of Two-Mile Creek — all show a friable, basic igneous tuff which is easily eroded or weathered and abounds in brecciate ejecta. These always occur with dioritic material and frequently intrusions of felspar porphyry type are associated with them. ‘The exact relationship however could not be explained on the data available. This felspar porphyry which has a characteristic appearance also occurs on a 'ridge just N.W. of Marian and on Hardwick’s Ridge, E. of portion 1475, Parish Abingdon. Rhyolites. These rocks are best and most extensively developed in a belt up do 3 miles wide on the north-western side of a line from Mt. de Moleyns through Milton’s Knob, Banaghan’s Hill, The Leap and along Reliance Creek until they give place to the diorites referred to above which extend from here to the coast. S. of the river rhyolite caps the Green Knoll Quarry — of the same general type as that which is to be seen at The Leap. It also occurs in portion 641 Greenmount, E. of the Yellow waterhole, and N.E. bf portion 1235 Homebush and a similar type at the Grass-tree Gold Mine N.E. of Sarina. The cutting at The Leap and the quarry at Green Knoll especially seem to indicate the following succession — (a) the intrusion into the Bowen Series of the diorite, followed by ( b ) the overflowing of these rocks by several sheets of rhyolite (not necessarily contemporaneous). Good examples of these rhyolite flows may be seen in the cuttings between The Leap Railway Station and The Leap; while the general sequence is best seen at Green Knoll Quarry. This rhyolite is frequently friable in nature. GEOLOGICAL NOTES ON THE PIONEER RIVER BASIN. 75 Speaking generally the more acid types, with preponderance of rhyolites and sometimes the occurrence of granites (and their normal aplitic modifications) with which they are associated, are in evidence at Nicholson’s Crossing, Mirani Bridge, the southern flanks of Mt. de Moleyns, the N. end of Reeve’s Creek, Milton’s Knob, Banaghan’s Hill, Up. Balnagowan Creek to its head (and down its eastern side to the E. side of portion 31v parish Hampden), then from portion 1356 Hampden along to The Leap, then along to portion 483 Bassett. From The Leap a spur of rhyolite runs S. to the S.E. of portion 496 Bassett where it approaches Turner’s Sugarloaf. The rhyolite ends at the S.E. of portion 757 parish Bassett, giving place to a diorite spur which runs up past its end to Galea’s scarp. Obsidians associated with the rhyolite are to be seen in the cuttings between The Leap and The Leap Railway Station, and also on the W. side of portion 1051 parish Hampden and in the S.E. of portion 500 parish Hampden; also at Mr. Peach’s home Sub. 67 parish 474 Hampden they are particularly interesting. Granophyre? occurs at the Pleystowe Railway Station. Aplites are found at the Quarry Hill, N.E. from Mt. Oscar and at the old Quarry at Mt. Bassett. Trachyte. Gibb Maitland has recorded the occurrence of trachytes at Mt. Yince, Mt. Jukes, Mt. Martin, and I would record here the occurrence of a trachy-rhyolite at Mt. Ossa. Granites. Grey Granite is found at Mt. Dalrymple and the Ben Mohr Spur. Other localities in which granite types occur are Kungurri, a scarp (running from Mt. Dalrymple S.E. to Dunwold, Connor’s Range, Mt. Bridgman, Mt. McBryde, Ben Mohr and Blue Mountain. At Flat Top II Island and Round Top Island a red granite occurs. At Eton Hill quite an extensive microgranite occurs. Sediments. Where the sediments of the Bowen Series are to be seen they are frequently markedly indurated from the effects of the later igneous intrusions and extrusions. Contacts of this nature occur at Pleystowe Railway Station, in the ' river bed at Pleystowe, at Green Knoll Quarry, New Walkerston Quarry. | portion 105 parish Greenmount and on the eastern side of the stony | divide between Baker’s Creek water and Sandy Creek water and the | Boomerang Lagoon — the eastern foot of these stony ridges producing bog iron-ore and excellent road-binding material due to seepage. Some bog iron-ore is found on the eastern side of portion 1027 parish Abingdon ' and on the extreme southeast of portion 474 parish Bassett. M 76 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. The general attitude of the sediments of the area cannot be assessed due to (a) their infrequent occurrence without an igneous cover; and ( b ) where they are visible in cuttings and sections they are invariably covered with the igneous material and no dip or strike could be measured. Notably, patches of these sediments occur in small extent west of Eimeo, in a cutting north of the Black Mountain but nearer Etowri, near Cox’s, portion 474 parish Hampden and, as mentioned before, small patches at Pleystowe Mill, Pleystowe Railway Station and Green » Knoll. No fossils, coal or oil of any significance have been noted. Copper has been worked at Bentley’s (Pinevale) and Bong Bong, with rumours of a small showing of copper at Cazzulino’s and a poor coal at Griffith’s (Two-mile Creek). Some quartz crystals have been found near Wundaru, but, speaking generally, the nature of the igneous cover does not tend to reveal metallic or mineral wealth in the Pioneer basin. My thanks are due to many kind friends in the Mackay district, whose assistance in transport, hospitality, &c., was invaluable. Vol. LVI, No. 8. TRYON MEMORIAL LECTURE. 77 Henry Tryon — First Hon. Secretary, Royal Society of Queensland, and his place in Queensland Science. By C. T. White, Government Botanist, Brisbane. (Read before the Royal Society of Queensland, 30 th October , 1944; issued separately, 25 th June, 1945.) Henry Tryon, one of the outstanding personalities of the early scientific life of Queensland and a contemporary of such well-known figures as R. L. Jack, F. M. Bailey, Jos. Bancroft and C. W. De Vis, came to this State about 1882 and obtained his first official position as an assistant at the Queensland Museum in 1883. He was born at Buckfastleigh, South Devon, England, on 20th December, 1856, and died at Brisbane on 15th November, 1943. After a primary education at Sherwood College, he became a medical student at the London Hospital, one of his instructors being the celebrated Ray Lancaster, for whom throughout his life he had the profoundest regard. Medicine, however, apparently did not appeal to the young man as a profession and he left the hospital before completing his course and turned towards the study of natural history. Tryon was a naturalist of the old school in the sense that he was interested in all branches of natural science and had a good working knowledge of geology, insects, shells, birds, plants and general zoology. The more exact parts of the natural sciences such as taxonomy and anatomy appealed to him more than the philosophical, and thus it was that Darwinism, with all its subsequent bearing on biological science, passed him by so that he always seemed quite unaware of its very existence. An indication of his outlook on science may well be ascertained from the subject of his presidential address before the Queensland Field Naturalists’ club in 1908 — “ Linnaeus and Buff on. ” It was of their type that he was a great admirer. One of his earliest exploits in natural history soon after leaving the medical school was to travel through Sweden following the tracks of the great Linnaeus collecting plants and insects, particularly the former. This was a great joy to him, and in later years he often lived this trip over again in memory. Later he journeyed to New Zealand managing a grazing property for his father, but here again the love of nature called him away on a lengthy collecting tour. New Zealand hills having too strong a pull for him to resist. He became friendly with Thos. Kirk and paid special attention to the botany of New Zealand. It is pleasing to know that his collections, which were extensive, have found a permanent home in the Queensland State Herbarium, from where duplicates when available have been distributed to kindred institutions. New Zealand made a strong appeal to him and he always retained pleasant memories of the time spent there, and never lost his knowledge of the Maori language. The life of a grazier made no appeal to him, and hearing of the great possibilities of the sugar industry in North Queensland and wanting to do something fresh, he decided to come to this country. He travelled a great deal over much of North Queensland looking at sugar lands, but there was one life that Tryon was destined for, and that was the pursuit of natural science. In 1883 he received his first appointment as an assistant at the Queens- land Museum, then under the directorate of C. W. De Vis. After some years as Assistant Curator at the Museum, Tryon was appointed, in 1894, N 78 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. as Government Entomologist in the youthful Department of Agriculture, later Department of Agriculture and Stock, and in 1901 became also Government Plant Pathologist, holding the dual position until his retire- ment in 1929. During these years he published many records of insect, fungus and bacterial pests in his annual reports, which were mostly of a voluminous nature. One of his earliest Departmental reports was on the insect pests of the orange orchards of the Wide Bay district published as Bulletin No. 1 (2nd series) of the Queensland Department of Agriculture in 1894. Before this, however, and while he was Assistant Curator of the Queensland Museum, he was commissioned by the Govern- ment to visit the Darling Downs and report on the diseases of orchard trees and agricultural plants. The results of this were published as a parliamentary paper under the title of “Inquiry into Diseases affecting the Fruit Trees and other Economic Plants in the Toowoomba District.’ ’ The Government, however, thinking this in the words of the then Secretary for Public Lands (Mr. Hume Black) “Too valuable to be confined to the shelves of a parliamentary library,” decided to publish it as a special “Report on Insect and Fungus Pests No. 1” of the Department of Agriculture, 1889. Tryon was a man of very keen eyesight and was fond of examining everything he picked up with a high power, small-field hand lens he invariably carried. He was an expert section-cutter with the ordinary hand razor, many of his sections I well remember having the appearance of being cut with a heavy sliding microtome. He was a man of very sharp scientific intellect, but unfortunately once he had made a discovery was not inclined to tackle the drudgery of writing up his results in a carefully prepared manuscript suitable for presentation to the scientific public. Thus it was that much was never published at all and other material was presented in a form scarcely worthy of its importance. In this connection it must be recognised that Tryon during the whole of his professional life for nearly fifty years was inundated with queries ; before the days of stenographers and typewriters all of these had to be answered by hand, and many of his letters were almost scientific treatises in themselves. From his arrival in the colony (now State) to almost the day of his death Tryon took an active part in the scientific life of Brisbane. He was the first Hon. Secretary of this Society, and Yol. i. of our Proceed- ings contains a paper on the “Savo Megapode” of the Solomon Islands by A. H. Kissack which was communicated by Henry Tryon and a short note by Tryon himself on “A Locust Plague on the Lower Herbert.” The early volumes of this Society contain several papers by Tryon, but he ceased to contribute after a time, most of his work appearing in the publications of his own Department. After a lapse of many years, on 27th September, 1926, he again read a big paper before this Society on “Queensland Fruit Flies ( Trypetidae) , Series I.,” which was published in Yol. xxxviii. of our Proceedings. This was the last big piece of research work Tryon published. He was elected an Honorary Life Member of the Society in 1929. It is interesting to note that this Society, largely through the efforts of its early Hon. Secretary, was able in 1888 to send H. 0. Forbes, the well-known naturalist-explorer, the sum of £100 in aid of his work in New Guinea. Forbes, though a capable naturalist and well known for his work in Sumatra, Timor and some of the lesser known islands of the Malay Archipelago, had great difficulty in financing this expedition to New Guinea, and in consequence his travelling in that country was much TRYON MEMORIAL LECTURE. 79 curtailed. A large camp was established at Sogeri and it was around about here most of his collecting was done. Tryon was the first president and one of the founders of the Natural History Society of Queensland which was formed in 1892 and had but a short life, ending so far as I can find in 1894 or 1895. The Society published one volume of ‘ ‘ Transactions, ’ ’ which contains four papers by Henry Tryon. He apparently never took an active part in the Field Naturalists’ section of our Society, which flourished about the same time. This latter from the commencement was mainly botanical, no doubt due to the activities and leadership of Frederick Manson Bailey. The first report of this section appeared in Yol. iv. of our Proceedings, 1887, and the last in Yol. x., 1894. From this date the section lapsed, and it was not until 1906 that another Field Naturalists’ Society was established, the present Queensland Naturalists’ Club, of which at an inaugural meeting on 6th April, 1906, Sydney B.( J. Skertchly was elected President and Henry Tryon Yiee-President. Tryon always took a very prominent part in the activities of this Club and in the early days organised many of the longer excursions. He was also a President of the Gould League of Bird Lovers, afterwards incorporated as a section of the Queensland Naturalists’ Club under the title of the Nature Lovers’ League. Tryon was also a fairly regular attendant at meetings of the Royal Geographical Society of Australasia (Queensland Branch), but so far as I know, except on one or two occasions, took little active part in the work of the Society and never contributed anything to its journal. In August, 1895. Tryon was appointed to visit British New Guinea (now the Territory of Papua) to collect sugar-cane varieties, which were sent to the State Nursery at Kamerunga, near Cairns, the Sugar Experi- ment Station, Mackay, and the Department of Agriculture in New South Wales. He had with him as assistant Mr. John Liverseed, of the Queens- land Department of Agriculture, afterwards manager of the State Farm, Hermitage, near Warwick. In his work, “The Queensland Sugar Industry,” Mr. H. T. Easterby, the then able Director of the Bureau of Sugar Experiment Stations, referring to this visit states: “Mr. Tryon brought back sixty-six varieties, including the well-known ‘Badila, ’ which is considered to be the best variety ever introduced into Queens- land. The sugar industry undoubtedly owes a great debt of gratitude to the Department of Agriculture for this cane, to which the successful cane-growing in the North is largely attributable. Seeing that in many of these areas 95 per cent, of the cane grown is of this variety, it is not stretching the point to say that quite a number of growers owe their success as cane-farmers to it. ’ ’ Tryon had always taken a very keen interest in the biological control of insect, fungus and plant pests, and as early as 1899 had suggested the possibility of the control of prickly-pear by natural enemies. In 1903 he was instrumental in importing from India speci- mens of the wild Cochineal insect for trial in prickly-pear eradication in Queensland. Unfortunately, however, this importation did not succeed in the establishment of the Cochineal insect in Queensland. In a paper published in the “Queensland Agricultural Journal” for October, 1910, he strongly recommended that the “Government prosecute inquiries in countries wherein the wTild Cochineal insect or insects are indigenous, or have become naturalised on being introduced — e.g., Mexico, West Indies, Brazil, Argentina, Senegal, Cape of Good Hope, SO PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. and especially in India and Ceylon. ” There is no doubt, I think, that the suggestion eventually led to the appointment soon after (1912) by the Queensland Government of a travelling commission comprising T. Harvey Johnston (chairman), H. Tryon (member) and C. W. Holland (secretary) to visit the many countries where prickly-pears were indigenous or had been introduced and become naturalised, and to investigate means of control that might be applied in Australia. In “The Biological Campaign against Prickly Pear,” published in 1940 under the authority of the Prickly Pear Board, A. P. Dodd, officer in charge of Scientific Investigations, stated: “The commission spent eighteen months in visiting the many countries where prickly-pears were indigenous or had become acclimatised, and in its subsequent compre- hensive and most valuable report made definite recommendations for the introduction under safeguards of certain insects and diseases from America. During its travels the commission forwarded to Australia from Ceylon small stocks of the cochineals, Daetylopius ceylonicus and D. greeni; the former insect was successfully reared by Dr. Jean White- Haney at the Dulacca Experiment Station, was liberated in the field, and in the space of a few years almost completely destroyed the scattered areas of 0 punt id monacantha. At this stage it should be mentioned that among the prickly-pear insects encountered by the travelling commission was Cactoblastis cactorum, larvae of which were found in the Botanic Gardens at La Plata, Argentine. Mr. Tryon actually brought some of the caterpillars alive to Brisbane, but failed to rear them through to the adult stage. Had this effort been successful, the control of prickly-pear may well have been brought about years earlier than has been the case.” His wife predeceased him by some years and the death of his elder daughter shortly before his own death was a great blow to him, as he had bought a new house and arranged for her to live with him and keep it on after his death. A son died in childhood. He is survived by a married daughter (Mrs. Hubert Jarvis) and two grandchildren. In appearance Tryon was rather tall and of medium build — in later years inclined to be sparse ; he had a pale skin and always wore during the thirty-odd years I knew him a moustache and short beard. He was a distinguished-looking man and might be described as typically English in appearance, or perhaps we should say nobody would mistake him for other than an Englishman. He was a very vigorous man, and one of his favourite pastimes was taking long walks in the bush. On these occasions he usually walked with rather a loping gait, by which he could cover many miles in a day. On most of these natural history rambles he was accompanied by friends, but many walks were taken by himself. In spite of the fact that he is primarily known as an entomologist, it always seemed to me that plants claimed his main attention on these outings. He was a very keen geologist and a life member of the Geologists’ Association (Eng.). He always wore heavy suits of dark material, even in hot weather, a large black tie, and single standup collar. He had a ready wit, though his remarks were frequently on the personal side and sarcastic enough to create for him some enemies. His interests were not confined to science, broad though they were in that sphere ; but he was an omnivorous reader of history, theology, poetry, and the classics. He was a striking personality; his death left a decided blank in Queensland natural history circles, and severed a link with the earlier scientific life of the State. A complete list of his publications was given in the “Queensland Agricultural Journal” for August, 1929 (Yol. xxxii., pp. 178-183). 81 Vol. LVI, No. 9. + A NEW CERIOIDES WITH FOLDING WINGS (Diptera-Syrphidae) . By G. H. Hardy. ( Received 18 th October , 1944; accepted for publication , 21th November , 1944; issued separately , 25th June, 1945.) Genus Cerioides Bond. Between 1922 and 1927, Shannon divided this genus giving names that do not appear applicable to the Australian fauna. Ferguson (1926) applied three of these names, pointing out that not all characters cited by Shannon are present and there now seems to be no justification for separating C. breviscapa Saund. from C. subarmata C. & B. on characters used for the purpose; indeed they evidently form a natural group together with the new species described below. Thus only two groups can be retained to accommodate the Australian Cerioides until such times as the world’s forms become better known. Of the twelve species hitherto described, six belong to the breviscapa-group, distinguished by the constriction near the base of the abdomen being excessive and wasp-like, and to this group the new species is added below’. The ornata-g roup has but a slightly constricted abdomen. Cerioides breviscapa-group. The two species which I myself have captured in the bush, had their wings folded longitudinally when at rest, a character reported by me in 1933, and I would suggest that all species with the character belong to one natural group, but it is uncertain as to how far this extends in* the group as at present understood. The character is readily overlooked as the flexure neither occurs readily when in the relaxed condition, nor is the flexure retained at death. The wing is flexed upwards, bringing the halves, rear above fore, to lie in parallel planes and not touching. Seen from above, the line of flexure shows three straight lines meeting at two points, forming two obtuse angles. This line of flexure has been traced by Mr. Edgar Biek and myself, using a freshly captured specimen of C. subarmata , caught by Mr. Biek on the large swamp at Sunnybank in August 1944, and this assures that on all pinned specimens with a wflng folded, the feature is identical with that of the living state.

Characters given in the key are taken from descriptions, as the material available for study is insufficient for a full revision. It will be noted that not only does sexual dimorphism occur within the* group, but also the males of three species are unknown, as also the female of one ; hence it may be considered that subarmata and mastersi are opposite sexes of the same species, but colour marks and their respective habitats differ so widely that they cannot be conspecific.

Ferguson overlooked this synonymy and neither he nor I had seen Yictorian specimens, but judged the identity from specimens found in New South Wales. As markings are liable to variation in this group, such small discrepancies as those found in the descriptions arc not important enough, nor sufficient in number, to permit acceptance of more than one species. Moreover, the genus is mainly a northern one, A NEW CERIOIDES WITH FOLDING WINGS. 83 ten of the thirteen known species being in Queensland and only four of these ten having yet been recorded from more southern States. It seems quite unlikely, therefore, that more than one species of the group here dealt with can occur in Southern Victoria, and none are to be expected from Tasmania, this being in conformity with other genera occurring mainly in Queensland. Ferguson comments upon the type locality “Port Phillip, South Australia ” as an apparent misstatement. Nevertheless this was quite correct, and the only alternative would have been “New South Wales ” which, at that time, covered the eastern half of the continent which was just beginning division into States The use of “South” referred to location in the sense of southern, not to the State of that name which was proclaimed a colony eight years earlier, 1836.

The yellow lateral spot at the transverse suture may become brown, reduced or entirely absent, and the scutellar margin may similarly become brown, as also the margins of the abdominal tergites.

Jensen, D.Sc. {From an address delivered before the Royal Society of Queensland , 2 6th June , 1944; received for publication and accepted 28 th November, 1944; issued separately, 29 th June, 1945.) 1. INTRODUCTION. There is a popular mis-statement very often repeated to the effect that Australia is the oldest continent in the world. There is some biological foundation for this belief in those animal and plant survivals of mesozoic types of fauna and flora indigenous to Australia, such as marsupials, the platypus, the macrozamia, inter alia, but such survivals after all only indicate a condition of isolation extending back for considerable periods. Geologically Australia consists of old lands and new lands. A considerable, in fact major, proportion of West Australia, the Northern Territory and South Australia is composed of formations belonging to the Archaean, Proterozoic and Cambrian, while newer formations dominate in the eastern States, considerable portions of the Murray Valley area being capped with Tertiary. Central Australia contains some of the oldest geological formations in Australia, but it would be a wild, unfounded and unproved state- ment to assert that these formations are older than other ancient gneissic areas such as those of the Canadan shield and of Central Brazil. Even when an enthusiastic geologist tries to bring together in point of time formations of the older proterozoic in remotely distant portions of Australia he treads on dangerous ground. Honman, for several years senior geologist of the Aerial, Geological, and Geophysical Survey in Queensland, being himself a West- Australian, assigned to various formations in the Cloncurry district the same names as similar formations had been given in Western Australia. Much as one may admire Honman ’s endeavour to simplify and connect up, the facts were insufficient to warrant the correlations implied. For the present it is better to use the alternative Queensland names of these formations, such as the Soldier’s Cap, and Mt. Isa series, without any implication of the one being equivalent to the Warrawoona or the other to the Mosquito Creek series. The key to the correlation of the proterozoic rock of Eastern and Western Australia has to be found by the closer study of the rocks of the Northern Territory. Dr. Madigan (1931-1933), lecturer in geology at the Adelaide University, closely studied the Q 86 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. Macdonnell Ranges, and divided and named the formations from oldest to the Ordovician as follows : — 1. Arnnta Complex, very old gneisses, etc. 2. Perta-knurra, schists and quartzites with limestone. 3. Pertatataka, quartzites and limestones. 4. Pertaoorta, Cambrian quartzites and limestones. 5. Larapintine, Ordovician quartzites, shales and marl. The names seem an abomination (and David (1932) spells Perta- as Pata-), but nevertheless the divisions made by Dr. Madigan are useful and safe. Correlation of these formations with others in remote parts of Australia depends on extended investigations in intermediate areas. The writer has had occasion to investigate the Lawn Hill and Territory border area in Queensland, the Woologorang and Borroloola area on the Territory side, and fairly extensive stretches north of the Plenty River and also between Anningie and Barrow Creek in Central Australia, besides having made extensive geological surveys between the Gulf of Carpentaria and Port Darwin. Some tentative correlations will therefore be ventured, in this paper, although they should be regarded mainly as a basis for future investigation. II. THE CENTRAL AUSTRALIAN MASSIF. The Macdonnell and Hart’s Ranges taken together constitute a massif of gneissic rocks, both of igneous and sedimentary origin. Together they form an anticlinorium built up in an archaean geosyncline. In general the strata in the Hart’s and contiguous Strangway Ranges dip to the north, and those in the Macdonnell Range, which lies south of the former, dip to the south. Minor rolls occur on these two general dips but it is safe to say that the limbs of the anticlinorium have an average dip north and south respectively of about 30°, and it was on that evidence that the late Sir T. ,W. E. David postulated a mountain range upwards to 50,000 feet high in Central Australia in pre-Cambrian times. The pre-Cambrian uplift was oval. The average strike in the Hart’s and Strangway Ranges is not quite east- west but rather W.N.W.-E.S.E. However towards the western end of the Hart’s Range the dips tend to become north-westerly, and towards the eastern end north-easterly. The Macdonnell Ranges strike more nearly east-west in the portions closely examined by Madigan. That investigator {op. cit.) has given such an excellent and detailed account of the Macdonnell Ranges; that nothing further need be said here about them. THE GEOLOGY OF CENTRAL AUSTRALIA. 87 Right in the township of Alice Springs, between the railway station and the hospital, there is a notable hill of orthogneiss (gneissic granite) called Billy-Goat Hill. Along the northern road for 55 miles north of Alice Springs all the outcrops are gneissic and mostly gneissed igneous rocks, such as gneissic porphyries, gneissic porphyrites, gneiss-amphibolite, etc. These gneissic igneous rocks appear to be the oldest group of rocks in the massif. The Macdonnell, Hart’s and Strangway Ranges, which form the massif, are extremely rough in nature. High sharp ridges, often with cliff faces on one or on both sides, steep cones and pyramids are a constant feature. Alice Springs lies at an elevation of 1,902 ft. but the nearby Macdonnell Ranges reach to 3,000 and even 4,000 ft. The plain north of the Hart’s Range is also 1,900 ft. in elevation near the foothills, yet large sections of the range average over 3,000 ft. in elevation and peaks reach up to 3,600 and 3,800 ft. Nevertheless these high ranges are traversed here and there by passes of much the same elevation as the nearby plain. Such natural breaks are of structural origin, water erosion having cut gorges along fault planes or dykes. The great Central- Australian mountain uplift was already very dissected before the earliest Cambrian strata were laid down, although, as Madigan ’s papers show, further uplifts took place in the Proterozoic and Cambrian in the same area. There are two peneplains in evidence in this region, both of Tertiary age, one about 600 ft. higher than the other. The lower and more recent one is that of Alice Springs and the plains around the ranges. It is probably post- Tertiary. The older peneplain (Birt Plain peneplain) is probably Miocene or Pliocene. Both these peneplains drop in elevation in all directions from the Cental Massif. A slow uplift has been taking place in the Massif area in post-Miocene times. The geological formations represented in the Hart’s and Strangway Ranges are much the same as those represented in the Macdonnell Range. The oldest rocks in Central Australia are known as the Arunta Complex. Rocks of this series only occur in the Hart’s and Strangway Range proper, though south of the main Hart’s Range (towards the White Range) where it merges into the Macdonnell Range, formations belonging to the Perta-knurra and Pertatataka enter into the mountain building. The oldest formations of the Arunta complex are strongly metamorphosed and gneissic granites, porphyries and porphyrites, and amphibolites are represented in them. The next oldest is a series composed of metamorphosed and gneissic sedimentary rocks with inter- calations of crystalline limestone. There are basic biotite-amphibole gneisses formed from basic tuffs, biotite gneisses formed from calcareous sandstones, and felspathic and quartzy gneisses formed from sandstone and grit ; and apparently interbedded with these are zones of amphibolite derived from basic volcanic flows, or perhaps from sill-like intrusions, 88 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. or both. The latest formations in the Arnnta complex, within the Hart’s Range, lying in a few places unconformably on the gneiss series, consist of quartzites, slates and schists. There is reason to believe that this formation is composed of remnants of the Perta-knurra series. North of the Plenty River and fringing the boundary of the Arunta Complex there are areas and ranges built up of schists, quartzites and arkoses and slates, highly inclined and often vertically bedded. These belong to the Perta-knurra Series of Madigan. They were strongly folded up against the older massif of Aruntan rocks. The same series is noted in the Anningie Ranges west of Barrow Creek, consisting here of hematite-mica-schist, and quartzite. This series ( Madigan ’s Perta- knurra) is probably identical with the Mosquito Creek Series recorded in other parts of the Territory and Western Australia. Both the Arunta Complex and the rocks of the Perta-Knurra Series are traversed by abundant amphibolite and pegmatite dykes. The later series are not affected by them. It is therefore obvious that at the end of the Pertaknurra (or Mosquito Creek) period there were great igneous intrusions accompanying the folding of the rocks of that period. In the Anningie area pegmatitic and gabbroic amphibolite dykes appear as complementary dykes. Outcrops of granite of this period show up in the Huckitta area and Tower Rock area north of the Plenty River. It would take too much space to recapitulate Madigan ’s work in the Macdonnells. It is sufficient to remark that the formations north of the Hart’s and Strangway Ranges are, with minor modifications, much the same as those south of the Macdonnell Ranges. The Plenty River rises in the western portion of the Hart’s Range and sweeps in an arc about 10 to 20 miles north of that range easterly and then south past the east end of the Hart’s Range towards the Simpson Desert. Both south and north of the east-flowing part of this river there are table hills taken to be residuals of the Cambrian. These hills show only low dips. North of the Plenty River the Arunta Complex is frequently fringed by the Pertaknurra or Mosquito Creek Series, steeply dipping and highly metamorphosed quartzites and hematite and mica schists. Overlapping these, and only low-dipping, there is an extensive series of quartzites with some rhyolitic and basaltic rocks interbedded, but containing no quartz reefs or pegmatite dykes. There are fault zones in these with the fault breccia chalcedonie. Over- lying these and dipping at similar low angles and seemingly conformable to the previous there are extensive areas of quartzite and limestone which are regarded as Cambrian, as Cambrian fossils have been obtained in them in places. The conformable fiat series under the Cambrian has been regarded as the Pertatataka by Madigan, and the occurrence of volcanic rocks in the series brings about a close similarity to the Nullagine. THE GEOLOGY OF CENTRAL AUSTRALIA. 89 That raises the question “What is the Nullagine”? Wide areas in the Northern Territory and Western Australia have been assigned to the Nullagine, which series is usually found to consist of interbedded sandstones, conglomerates, slaty-shales, and limestones with intercala- tions of volcanic rock, trachyte, andesite, dacite, basalt, etc. David in “Explanatory Notes” stated that the Cambrian in Australia was remarkably free from volcanic action and igneous intrusions. That appeared to be true for the areas studied by him. If that statement is capable of general substantiation the limestone quartzite series carrying interbedded lavas in north-west Queensland, the Northern Territory, Central Australia and Western Australia must all be regarded as Nullagine. The more deep-seated intrusions which caused mineralisation in the series must also have been Nullagine. Thus the Wollogorang copper-field, the Maranboy tinfield, the Macarthur River silverlead deposits, and possibly the Hatch’s Creek wolfram field, and perhaps also the Tennants Creek gold-field and many other Territory fields could be regarded as Nullagine mineral deposits. Now there is no stratigraphical break between the so-called Nullagine and the Cambrian in most of the areas investigated by the writer. Wade in his long traverse of Northern Australia from the Kim- berleys to the Gulf of Carpentaria came to the conclusion that much of the so-called Nullagine was Lower Cambrian. He regarded the strong stratigraphical break between the highly folded metamorphic rocks and the gently rolling quartzite-limestone series as the base of the Lower Cambrian, whether fossils occurred in the rocks overlying the uncon- formity or not. Thus the Antrim basalts, which David placed in the Nullagine, according to Wade lie between the lower and Middle Cam- brian. The Edith River volcanics occupy practically the same horizon. The writer agrees absolutely with Wade’s viewpoint. The andesitic and rhyolitic volcanic rocks in the Wollogorang copper-field seem on all known stratigraphical evidence to occupy a horizon in the Lower Cam- brian. Tuffy horizons occur in the Cambrian Barkly Tabeland series between Anthony’s lagoon and Macarthur Station. The writer found a long wide diorite dyke penetrating a limestone-quartzite series near Macdonald Downs Station, north of the Plenty River ; the invaded rocks were regarded by Madigan as well as by the writer as Cambrian both on lithological and nearby fossil evidence. Moreover, rocks of an entirely Cambrian facies carry copper lodes on Yah- Yah Creek; some miles from Macarthur Station; the Wollogorang copper deposits, dis- seminated deposits, and the silver-lead and copper bearing reefs near the Nicholson River on the Border are in what appear typical Cambrian formations ; and Cambrian limestones contain abundant nodules of native copper near Delamere and Willaroo Stations in the Territory. 90 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. Evidence collected on the Lawn Hill field (N.Q.) indicated that a granite intrusion at a depth, and not showing on the surface, had uplifted the area forming a number of domes. The lower or Lawn Hill Series, which may well on existing evidence be regarded as Lower Cambrian, was greatly affected by the intrusion, and the upper, Con- stance Range Series only slightly, as though by expansion through crystallisation of the intrusive rock below. The Lawn Hill Series is traversed by quartz reefs many of which contain rich lead deposits. The break in the Cambrian during which volcanic and intrusive action took place corresponds well to the break in the Templeton Series in the Cloncurry district. On present evidence the Nullagine is a geological scrapheap which will have to be cut out or reduced. Much of it will as investigation proceeds be found to be Lower Cambrian. The Adelaide Series, the lower part of which David placed as equivalent to the Nullagine, is undoubtedly Proterozoic and pre- Cambrian. The great glacial period was late Proterozoic and anteceded Archaeocyathinae. Evidence of glacial action of Pre-Cambrian age occurred as far north as Borroloola. Cores from bores put down in 1912, and outcrops of intercalated fine sandstone and shale in the Macarthur River gorge, showed periglacial involutions similar to those described from North Eastern Illinois by Robert P. Sharpe in J. Geol. 1, No. 2, Feb-March, 1942. The beds in which these periglacial involutions occur are moderately folded and underlie the more gently dipping Cambrian rocks of the Barkly Tableland unconformably. Along the Northern Road Telegraph Line from Alice Springs rocks of the Arunta Complex only are seen in outcrop for the first 70 miles. A small range, called the Hann Range, through which the road runs before reaching Aileron, and its westerly continuation, the Reap- hook Hills, consist of red quartzites dipping north at 20°, with some reddish shingly or slaty rock intercalated. These rocks are heavily faulted. They appear to belong to the Adelaide Series. A few miles further north at Aileron rocks of the Arunta Complex again appear. Beyond Aileron there are more low gently dipping sandstone ranges, the Reynolds Range, and these too probably belong to the Adelaide Series. North of these towards Teatree, which is about 110 miles from Alice Springs, extensive areas are capped with volcanic rocks — andesite, trachyte and tuffs of these. At Teatree these rocks have been intruded by a laccolite of blue granite. Silver ore is said to occur in kaolinised tuff in hills north-east of Teatree. North- west of Teatree there is a group of high rounded treeless hills and some spurs with cliff escarpments forming the Central Mt. Stuart group. These hills have a remarkable physiographic resemblance to Lawn Hills and have a similar dissected dome structure, and in the valley between the peripheral hills there outcrops a laccolitic mass of porphyritic felspar granite. This granite is in character very like that on the Queensland border north of the Nicholson River. Some of the Central Mt. Stuart THE GEOLOGY OF CENTRAL AUSTRALIA. 91 hills are traversed by large quartz reefs while others of exactly the same formation have not been invaded by quartz, in which respect also the hills resemble the Lawn Hills. East of Central Mt. Stuart the road crosses some low hills called the Stirling Hills. The rock outcropping on these hills is thinly inter- laminated, coarser and finer red sandstone (dipping very gently north), which appears to be of glacial origin. In the valley north of these hills there are basalts, andesites and rhyolites, tentatively assigned to the Nullagine. Further north at Barrow Creek faulting again brings the Arunta Complex to the surface, and north of a narrow east-west horst of Aruntan rocks there is a large intrusion of porphyritic dark granite. This is followed further north by more formations of volcanic nature, a mass of rocks of Mosquito Creek formation on Neutral Downs, and another mass of Mosquito Creek rock further west at the Anningie tin- field. Several other ranges further north consist of quartzites and schists probably of Mosquito Creek age, but no rocks of a Cambrian limestone facies were seen along the Northern Road, south of Wauchope Creek. The Cambrian sedimentary rocks are probably much more extensive in the Eastern half of Central Australia than in the western half. In the eastern half they extended with interruptions from the Plenty River to Lawn Hill. In the Western half the volcanic rocks of andesitic and trachytic nature are very widespread, and though they are at present regarded as Nullagine they may be Lower Cambrian. They are said to dominate over most of the country between Teatree and the Granites. The writer has not personally been beyond Anningie from the Alice Springs end, nor beyond Tanami from the Darwin end. The volcanics in the Anningie area north-west of Teatree show a strong tendency to laterisation and kaolinisation with subsequent dissec- tion of the laterites. This appears to be the result of a wet climate in the Pliocene or thereabout. The only extensively developed rock series later than the Cambrian in Central Australia is the Ordovician Larapintine System consisting of gently folded to flat calcareous sandstones, shales and marls. They contain no dykes or intrusions whatever, according to experience up to the present. There are small pockets of late Tertiary rocks in many places, and large areas capped often to a depth of up to 600 ft. with wind-blown sand. The valleys now filled with these quaternary sand deposits were probably carved in the moister Pliocene period. III. MINERAL DEPOSITS IN CENTRAL AUSTRALIA. Central Australia is not rich in economic minerals, at least not the easily accessible parts. 92 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. South of the Macdonnell Ranges at Rumbellara there are ochre* deposits worked. In the Hart's Range and in the Strangway Range there are numerous muscovite deposits and at least one large phlogopite deposit. The commercial muscovite always occurs in lenticular mica- rich shoots or bunches in pegmatite dykes. The phlogopite mica is in the main occurrence developed in an ultrabasic dyke which has differen- tiated into an olivine rock in the centre (dunite) and augite-enstalite rocks on the two walls. Each of the three sections is 30 ft. or more in width, and the phlogopite occurs along veins in the olivine rock. Potassic solutions from the later pegmatite dykes have played a part in producing the phlogopite. This occurrence is in the Strangway Range. Phlogopite in small uncommercial books occurs in several other localities, e.g., in basic dykes in the Hart's Range and in limestone as well as gabbro at the large apatite deposit 90 miles from Alice Springs on the Hart’s Range Road. The apatite occurrence mentioned is one of great dimensions and excellent purity. It is produced as a pneumato- lytic emanation from a large basic intrusion and largely replaces Aruntan crystalline limestone. Garnets are very abundant in numerous formations in the Hart’s and Macdonnell Ranges, and they are most plentifully and perfectly developed in certain amphibolite zones. Though ruby and sapphire should occur in the Central Australian massif, it is. doubtful if any have yet been found. The Macdonnell Range ‘‘ruby”’ is mostly garnet. There is in the Hart’s Range an asbestos occurrence of some magnitude, and in the plains north of the Plenty River there are large kaolin deposits fringing the Aruntan rocks. In Mount Strangway there are large developments of kyanite rock accompanied by staurolite. How- ever all these minerals are so low-priced that it does not pay to mine any except the mica. Beryl occurs in the pegmatite dykes but is subordinate in amount. In addition to mica, wolfram, tin and tantalite are pegmatite minerals; but as these minerals hug the contacts of the large granite masses and as the granites from which the pegmatite dykes are offshoots are deeply buried under the Hart’s and Strangway Ranges these minerals do not occur in that area, but do make their appearance in both Aruntan and Mosquito Creek rocks where intrusive granites occur nearby. Thus wolfram occurs in an aplite-pegmatite dyke north of the Plenty River and also in a similar rock about 10 miles north-west of Barrow Creek, the dykes in each case intruding Arunta Complex. Tin occurs with tantalite in aplite-pegmatite dykes at Anningie intruding Mosquito Creek rocks. In the Jervois Range, which the writer has not visited, about 300 miles north-east of Alice Springs, there are great silver-lead and copper deposits in fissure lodes in rocks which correspond to the Mosquito Creek Series, and at the Home of Bullion Mine about the same distance north of Alice Springs there are large copper lodes. But it does not pay to work these metals at present. Smaller copper lodes also occur about 80 miles north-east of Alice Springs in limestone of the Arunta Complex, TfiE GEOLOGY OF CENTRAL AUSTRALIA. 93 All the above minerals were introduced by the igneous intrusions which succeeded the deposition and folding of the Perta-knurra and Mosquito Creek sediments. Apart from mica and specially rich deposits of tin, tantalite and wolfram, the only profitably worked mineral is gold. The Tennants Creek field has come to stay. There is gold at the Granites and at Tanami, and there is a vast area of country north-west of Barrow Creek towards Tanami which may yet produce many good goldfields. Owing to* surface water being absent except in the heaviest of rains this area is difficult to prospect, and has not been properly prospected. In this area there are many laccolitic granite intrusions which belong to the Nullagine, or more likely early Cambrian period. These granites introduced copper, silver-lead and gold in places (as they have done north-east of Barrow Creek, at Wollogorang, Lawn Hill, etc., near the Queensland border) . As disseminated copper and lead ores occur in connection with this last igneous period, the evidence of ore deposits is obscure unless very careful search is made. There is a vast amount of geological work and work on ore deposits yet to be done in the Territory. IV. THE WATER PROBLEM. Central Australia is almost devoid of permanent waters, hence there is everywhere need for more bores. Unfortunately there are no artesian or even subartesian basins in this part of the Territory. Sub- artesian waters are more generally found about 400 miles north of Alice Springs in the extensive Cambrian belt of the Barkly Tableland and near the South Australian border also in the Cambrian. The vast inter- mediate area only carries water in odd small localised pockets, or in fault zones. Pegmatite dykes often serve to dam back and hold moderate quantities of water in fractures in the Aruntan rocks in the Hart’s Range. During the last couple of years a vast amount of water drilling has been carried out by the army and Allied Works Council, sometimes without competent geological advice ; hence failures have been numerous. The choice of bore sites is a task which can only be satisfactorily carried out by a competent geologist. Alice Springs is unique in Central Australia in having a large underground water supply. An eroded valley between the Macdonnell Range and Birt Upland Plain has been deeply silted up with sand and its outlet must have been partly blocked by land-slip. Consequently the floods of the Todd River and branches charge these sands with water, which can stand being drawn on heavily. V. THE SOILS. The ranges and hills in Central Australia have little soil and little vegetation. Between the ranges there are large plain areas in which bores in search of water have often gone 600 to 700 ft. before meeting with rock. The soils are windblown mostly, — a kind of loess. They are R 94 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. usually reddish in colour. If water were available for irrigation they would be highly productive, for the nature of their origin, viz., wind- blown detritus from all kinds of formations, ensures that they are rich in all mineral plant foods. At Alice Springs, with irrigation, magnificent citrus fruit and grapes are grown, and excellent vegetables can be produced wherever water is available. REFERENCES. David, T. W. E. (1932).

As the result of this work, a probable Miocene age is suggested for both The Narrows Tertiaries and the Petrie Series, and a probable Oligocene age for the Baffle Creek Tertiaries and the Redbank Plains Series. The environmental conditions of deposition and origin of the ostracod-bearing shales in the'se basins, together with other related data, are discussed. PART I.— INTRODUCTION. Introductory and Historical. The most abundant of the microfossils that have been found in the Tertiary shales of Queensland are the Ostracoda. They are sometimes so abundant, and other fossils are so rare, that a palaeontological study of the strata is virtually a study of the contained ostracods.

Although, ostracods have been recorded from seven of the Tertiary basins in the eastern part of Queensland, very little attention has been given to their systematic study in the past. The first reference to the occurrence of these small crustaceans in Queensland was made early in the year 1914, when Ball (1914a, p. 21) recorded “ great numbers of minute, flattened oval bodies’ ’ which he regarded “as the remains of ostracods” in the oil shales of the Baffle Creek Tertiaries between Bundaberg and Gladstone. Shortly after this, he (1914b, p. 73) also recorded “minute, reniform bodies — between and xV in. in length — showing in vast numbers on the bedding planes of some of the shales” of The Narrows Tertiaries between Glad- stone and Rockhampton, and stated that “they were much like the ostracod Cypris.” In 1916 Ball (1916a, p. 15), reporting on the Lowmead No. 1 Bore in the Baffle Creek Tertiaries, again referred to “the small, white, reniform bodies so characteristic of the shales, and especially of the oil shales” as ostracods. He mentioned that they were “seldom more than in. in diameter, and were enveloped by a thin, unsculptured, but cracked coat of a bluish-white, brittle, opalescent substance, which was found on chemical analysis to consist of carbonate of lime.” Later in the same year, Ball (1916b, p. 213) recorded from the Nagoorin Series, near Many Peaks, an “exposure of oil shales on Ubobo Creek, identical with those met in sinking and boring at Lowmead, even to the contained Entomostraca. ” In 1924 Jensen (p. 287), report- ing on the progress of the Australian Oil Corporation’s bore on Dunn’s farm near Beaudesert, 40 miles south of Brisbane, stated that “the shales from 140 ft. to 180 ft. contained abundant ostracod remains, especially from 160 ft.” Subsequently Ball (1924, p. 364) referred to these Tertiary ostracods and stated that “they are massed to the extinction of their individual outlines along some of the bedding planes, the proportion of ostracod to the total bulk of the shale reaching sometimes as much as 10 per cent., where several such crowded planes occur together.” In 1927 Jones (p. 38) recorded fossil ostracods from the Redbank Plains Series, in bituminous shales on portions 118, 119, and 120, parish of Bundamba, about 12 miles south-west of Brisbane, and described them as “numerous small oval bodies.” In 1932 David (Table I.) recorded “ostracod and sporangia shales” from the Diiaringa Tertiaries, between Rockhampton and Emerald. Ostracods have also been recorded from several places in the Petrie Series, north of Brisbane. In 1932, Ball (p. 384) discovered numerous small “flattened kidney- shaped bodies which Whitehouse identified as an ostracod allied to the genus Cypris in fissile, low-grade oil shales on the spoil heap of Simpson’s well, in portion 186, parish of Nundah, about one mile E.S.E. of Bald Hills. Finally, the present writer (1944) has recorded ostracods from Brecknell’s bore on portion 222, parish of Warner, north-west of Strathpine, from portion 190, parish of Warner, some two miles west of Strathpine, and from Houghton’s bore on portion 24, parish of Warner, about one-quarter of a mile north of Lawnton, stating that “in some cases the bedding planes of the shales are so packed with white, chitino-calcareous, carapace valves that other material is almost excluded. ’ ’ Only one short paper dealing with the systematic description and identification of any of these ostracods has so far been published — namely, Chapman’s “Report on Samples of Surface Tertiary Rocks and a Bore Sample containing Ostracoda from Queensland” (1935, pp. OSTRACODS FROM SOME QUEENSLAND TERTIARY BASINS. 97 66-71). In that paper Chapman described the ostracods contained in a small collection of samples from the Redbank Plains Series, the Australian Oil Corporation’s No. 2 Bore on Dunn’s Farm near Beau- desert, and the Lowmead No. 1 Bore in the Baffle Creek Tertiaries. He briefly described two new freshwater species, Erpetocypris aeqwalis and Cypridopsis compressa, and identified a third as the well-known estuarine and marine species Cythere crispata from the Redbank Plains Series. He also described a new species (?) Cythere queenslandiae and recorded Krithe cf. reniformis (Brady) from the Beaudesert Tertiaries, and stated (1935, p. 67) that although the Lowmead ostracods were too crushed to describe in detail, they were “apparently referable to the genera Pontocypris, Cythere, and Paradoxostoma.” On the evidence of the associated freshwater and estuarine or marine ostracods Chapman concluded that the Redbank Plains basin was a lacustrine area open intermittently to a shallow sea, that the Beaudesert Tertiaries were of shallow marine or estuarine origin, and that the Lowmead ostracods indicated a shallow-water marine deposit. Both Reid and Richards (1935, p. xiv), discussing this paper, however, have said that “field evidence could not support marine incursions of these basins.” With reference to the age of these Tertiaries, Chapman (1935, p. 70) stated that although “the Ostracoda give no very decisive data as to the age of the various beds other than Tertiary, the rocks may range from Lower Miocene, or even older, to Pliocene.” Apart from the above paper, Chapman (in Ball, 1932, p. 384) has briefly reported on the ostracods from Simpson’s well near Bald Hills in the Petrie Series, stating that “their generic affinity is very obscure, and that they can be referred to as (?) Cyprids only.” The present writer (1944) has also referred to the presence of Erpetocypris aequaLis Chapman along with other ostracods in the Petrie Series. Thus, although the Queensland Tertiary fauna is rich in ostracod remains, it is apparent that the detailed palaeontological study and identification of these small crustaceans is almost a virgin field. The Value and Limitations of the Queensland Tertiary Ostracods. Since the birth of the utilitarian science of micropalaeontology some twenty-five years ago, work on fossil ostracods has increased considerably in certain parts of the world. This has mainly been due to the import- ance of these small crustaceans in economic geology as it has been realised that they can be satisfactorily used for purposes of subsurface correla- tion. However, as most of this work has been directly connected with petroleum geology, it is not surprising to find that almost all taxonomic work has been carried out on marine and estuarine forms. This is unfortunate, for, while a large and comprehensive literature on marine ostracods has been assembled, very little work has been published in recent years on freshwater members of this order. In fact, the paucity of literature and previous work on Tertiary freshwater ostracods is at present a very real handicap, and involves a consequent diminution in the stratigraphical value of systematic palaeontological work. A number of factors contribute to the utilitarian value of Queens- land Tertiary ostracods. Although plants, freshwater molluscs, fish, and insect remains have been found in these freshwater Tertiaries, boring operations in several of the basins have shown that fossil ostracods are often almost the only. 98 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. if not the only, animal remains in quite considerable thicknesses of the deposits. In such cases they may be of value in determining the age of the strata, as well as in enabling stratigraphical correlations to be made. They are valuable also, since their small size enables them to escape destruction in the drilling operations which are essential for the adequate study of these Tertiary basins, owing to the limited nature and sporadic occurrence of outcrops. Moreover, although most of the ostracod valves are badly crushed, careful examination usually reveals well-preserved individuals with distinctive shape and ornamentation, so that more certain specific identifications can sometimes be made than is the case with other fossils. Another important factor is that some of the species have been found to be moderately short-ranged and, with the recognition of charcteristic faunal assemblages, the ostracods, accordingly, may be suitable for zonal correlation purposes within a basin. It must be admitted, however, that some of the simple, smooth-shelled ostracods are definitely long-ranged and consequently of little value for purposes of subsurface correlation. Owing to their wide geographical distribution, the ostracods have also shown themselves to be of value in indicating the stratigraphical relations of some of the different Tertiary basins. Taxonomic work on some of the ostracods, besides being of value for purposes of age determination of the strata, is also helpful in throwing light on the environmental conditions of deposition of the sediments. For instance, the referring of species found in bituminous shales to present-day genera which are known to frequent lake floors, creeping in the mud and feeding largely on algal material is suggestive, since this is the environment in which bituminous shales are actually formed. The presence of these ostracods then can be taken as an index to such conditions of deposition. Finally, the fact that other Tertiary fossils, apart from the fossil fish, are at present of little use for stratigraphical purposes, makes the ostracods all the more valuable as fossils. Opposed to these advantages there are certain disadvantages that limit the satisfactory utilisation of Queensland Tertiary ostracods. The minute size of ostracods renders their use in the field practically negligible, since accurate identification can only be determined with the aid of a microscope. Although they may be very abundant, the valves are usually very much crushed and broken, and this makes detailed work slow and difficult, since a prolonged search is needed to find material suitable for identification or accurate taxonomic description. This is particularly the case with the Cypridae, the members of which have thin, fragile shells, which are seldom met united, as they were only held together by ligaments in life. The assignment of the various ostracod species to their correct genera, also, is often a difficult task. This is due to the fact that the genera to which the Queensland Tertiary species are referable were originally described by zoologists and not by palaeontologists. The classification of recent Ostracoda is based principally on anatomical modifications and zoologists, while describing these with great care, have OSTRACODS FROM SOME QUEENSLAND TERTIARY BASINS. 99 given only unsatisfactory accounts of the structure of the carapace valves. In the case of fossil specimens, the shell is all that remains, and it is on the basis of its structures alone that the palaeontologist must make his determinations. Unfortunately, it is a fact that several ostracods with shells having essentially the same outline and surface characters have been described by zoologists as distinct genera. A final disadvantage is the fact that, although the ostracod faunas appear to bear a general resemblance to the present-day one, little work has yet been carried out on the recent freshwater ostracods of Queens- land. Accordingly, it is impossible at present to make any definite comparisons with the existing forms, quite apart from the fact that an element of doubt will always remain in such comparisons. In spite of the above limitations, however, the Queensland Tertiary ostracods are definitely valuable. In fact, after the Foraminifera, the Ostrocoda are now recognised throughout the world as the next most economically important group of microfossils found in sedimentary rocks. PART II.— SYSTEMATIC DESCRIPTIONS. In the following systematic descriptions Rupert Jones’ rule has been followed, where conclusive evidence is lacking, in regarding the thicker, or blunter, end of the carapace as the posterior extremity. Since the generic diagnoses are not readily available, they have been included. Order OSTRACODA Latreille. Suborder Podocopa Sars. Family CYPRIDAE Baird, 1846. Genus Cypris Muller, 1785. Genotype: Cypris piibera Muller, 1785, p. 56. Diagnosis: Carapace in lateral view reniform to oval. Dorsal margin variously arched. Ventral margin often sinuate, central portion usually somewhat incurved. Valves subequal, left valve usually the larger. Plinge edentulous, somewhat thickened, occupying about one-third dorsal margin. Surface of valves smooth to slightly uneven, often punctate. Range: Jurassic to Recent, mainly Tertiary to Recent. Cypris munduranensis, sp. nov. Plate VI, figs. 1 a, b. Holotype: F. 1976, Queensland Geological Survey Collection. Locality: Bore 4, at 170 feet. Parish of Targinie, County of Deas Thompson, between Gladstone and Rockhampton, Queensland. Geological Horizon: The Narrows Tertiaries. Description: Carapace small, in lateral view elongate-ovate to sub’reniform, highest slightly behind middle. Height slightly greater than one-half of length. Dorsal margin gently arched. Ventral margin nearly straight to slightly concave ' in median region. Anterior extremity somewhat obliquely rounded. Posterior extremity more broadly and evenly rounded. Valves moderately strongly convex. Convexity nearly uniform, but rising rather more steeply from ventral margin than from dorsal, and regularity interrupted by shallow transverse sulcus, crossing 100 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. valve obliquely, generally from in front of middle of ventral to behind middle of dorsal margin, and somewhat deeper dorsally. Position of greatest thickness of carapace located posteriorly, slightly behind middle. Left valve the larger, slightly overlapping right along ventral margin and the two extremities. Hinge somewhat thickened, occupying approxi- mately central third of dorsal margin. In profile acute-ovate, with transverse sulcus showing in median region, and with posterior extremity slightly inflated. In end view oval and tumid. Surface of valves entirely covered with minute, irregularly-arranged, rather inconspicuous tubercles, and shell pierced at intervals with minute punctations — normal pore canals. Four sub central muscle scars conspicuous, set in deepest part of transverse sulcus, generally closer to dorsal margin of shell, arranged in row sloping dorsally and posteriorly, and often contiguous or nearly so. Two central muscle scars larger and more elongate than lateral scars. Shell thin, fragile, chitino-calcareous, and transparent to translucent. Dimensions of holotype: Length, 0.52 mm.; height, 0.27 mm.; approximate thickness of carapace, 0.3 mm. Rema/rks: Cypris Miimduranensis does not closely resemble any of the described fossil forms of the well-known freshwater genus Cypris which today is so abundant in many stagnant pools. The carapace, however, is rather similar in structure to that of a recent, but as yet undescribed, freshwater species that has been collected from ponds and lagoons in S.E. Queensland. It also shows some general resemblance to the common species, Cypris gibba Ramdohr, which ranges from Oligocene to Recent. This is the most abundant species in The Narrows bore-core samples examined and, owing to its small size, a large number of undamaged valves and some complete carapaces were available for detailed study. In fact, the ostracod fauna in some of the samples from The Narrows is almost restricted to innumerable individuals of this species, and it has also been found to be common in the Petrie Series material examined. The specific description, accordingly, is based on a large number of specimens. The outstanding characteristics are the obliquely-sloping transverse sulcus containing the four muscle scars, the small size, and the rather inconspicuous tuberculate and finely punctate ornament — the tubercles under high magnification being seen as small, round, somewhat flattened prominences surrounded by shallow grooves, and each approximately 0.02 mm. in diameter. The variation within the species is not great, the most noticeable feature being in the relative position of the shallow transverse sulcus on the valves. While in most individuals this crosses the valves almost medianly, in some it is located closer to the anterior extremity, and in others closer to the posterior extremity of the valve. In such cases the position of the muscle scars on the valve also varies accordingly. However, after making allowances for apparent variations due to different degrees of crushing, the shape of all mature individuals of this species has been found to be nearly constant. Also, while some very minute and immature forms occur, the size of most individuals approximates to the dimensions given above for the holotype of the species. In some individuals the shell is thin and horny, but in others it is quite calcareous and much more solid. The species has been named after the important locality name of Munduran within The Narrows Tertiary Basin, where it was first found.

Diagnosis: Carapace in lateral view oval to broadly reniform, highest generally at about, or slightly behind, middle. Height consider- ably greater than one-half of length. Dorsal margin strongly arched. Ventral margin almost straight. Carapace valves rather compressed. Valves unequal, left overlapping right anteriorly, posteriorly, and usually ventrally, and right sometimes overlapping left dorsally. Free edges of left valve smooth, with chitinous border broader anteriorly and posteriorly than ventrally. Inner margin of right valve thickly tuberculate. Range: No Tertiary representative of this recent freshwater genus appears to have been recorded previously. Cyprinotus punctatus, sp. nov. Plate VI, figs. 4 a, b. Holotype: F. 1978, Queensland Geological Survey Collection. Locality: Bore 1, at 157 feet. Parish of Rundle, County of Deas Thompson, Queensland. Geological Horizon : The Narrows Tertiaries. Description: Carapace large, in lateral view ovate to broadly subreniform, highest slightly behind middle. Height approximately equal to two-thirds of length. Dorsal margin strongly arched, sloping more abruptly anteriorly than posteriorly. Ventral margin almost straight to slightly concave in median region. Anterior extremity broadly but rather obliquely rounded. Posterior extremity broadly and more bluntly rounded. Valves moderately convex to rather compressed. Convexity regular. Valves unequal, left overlapping right along ventral margin and two extremities. In profile narrow oblong-ovate, with anterior extremity somewhat more pointed than posterior, and greatest width slightly behind middle. Surface of valves polished, smooth except for numerous minute punctations representing closely-spaced normal pore canals. Marginal zone developed along ventral margin and twro extremities. Line of concrescence coinciding with inner margin, and running generally parallel to outer margin of shell. Marginal zone strongly chitinised and transparent, ranging in width to 0.1 mm., pierced by numerous radial pore canals opening internally along line of concrescence, externally near outer margin of shell. Radial pore canals closely spaced, about 0.01 to 0.02 mm. apart, sometimes in two or more series, long and short alternating, unbranched, narrow, each with bulbous enlargement near middle or between middle and outer margin. Shell thin to thick, chitino-calcareous, and transparent to opaque. 102 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. Dimensions of holotype: Length, 2-15 mm.; height, 146 mm.* approximate thickness of carapace, 0-8 mm. Remarks: The high, compressed shell of this ostracod is characteristic of the genus Cyprinotus. In outline it closely resembles Cyprinotus dentato-marginatus (Baird), which has been recorded by Sars (1889) from lagoons near Rockhampton. It differs from this recent species, however, in having the shell much more closely punctate, the valves slightly higher and nearly twice as large, and in the presence of the well-defined marginal zone pierced by numerous radial pore canals. It might be mentioned here that two species of Cyprinotus found in Australia today attain a length of over 2 mm. Although this species is not uncommon in some of the samples from The Narrows, owing to its large size and the subsequent crushing of the material, very few undamaged valves have been found. It has been possible in some cases, however, to reconstruct the shape from various fragments of the valves, and the above description is based in part on the information so obtained. The species is moderately long-ranged, and individually of no value as a zonal index. Moreover, it is generally rare in its occurrence, and in very few of the bore-core samples examined has it been found to be really abundant. The outstanding characteristics are the very finely and closely punctate shell, and the well developed marginal zone pierced by the radial pore canals. Variation in the number and arrangement of the radial pore canals and in the width of the marginal zone has been observed. In some individuals the radial pore canals are all of equal length, but in others Ihey are of two and sometimes three different lengths, though always alternating in a regular manner. Sometimes they are very close together and almost contiguous throughout their length, but in other individuals they are more widely separated. Generally they appear to end in the bulbous enlargement. The width of the chitinised zone also varies in different individuals, and it is usually somewhat wider anteriorly and posteriorly than it is ventrally. It might also be mentioned that in some young and immature individuals no trace has been found of the radial pore canals. In some individuals the shell is thin, rather feebly calcified, and fragile, but in others it is heavily calcified, much more solid, and quite opaque. The recent Cyprinotus is generally considered as a subgenus of Cypris, and belongs to the subfamily Cypridinae, members of which are capable of swimming as well as creeping. The species has been named after the very finely and closely punctate shell of this ostracod. Localities and Age: Bores 1, 3, 4, 5, 6, 12, 13 14 (see species occurrence charts), parish of Targinie and Rundle, county of Deas Thompson, The Narrows, between Gladstone and Rockhampton. This species has a vertical range of at least 182 feet, and its actual range may be considerably greater. Probably Miocene. Genus Ilyodromus Sars, 1894. Genotype: Ilyodromus obtusus Sars, 1894. Diagnosis: Carapace in lateral view oblong. Dorsal margin variously arched. Ventral margin practically straight to gently sinuated.. Valves equal, or left slightly larger than right. Carapace compressed. Hinge short, edentulous, somewhat thickened. Surface of valves usually ornamented with distinct lines or riblets, but sometimes smooth or very delicately striated. OSTRACODS FROM SOME QUEENSLAND TERTIARY BASINS. 103 Range : No Tertiary representative of the recent genus Ilyodromus appears to have been recorded previously. Ilyodromus ? concentricus, sp. nov. Plate VI, figs. 2 a, b. Holotype: F. 1977, Queensland Geological Survey Collection. Locality: Bore 1, at 157 feet. Parish of Bundle,, County of Deas Thompson, between Gladstone and Rockhampton, Queensland. Geological Horizon: The Narrows Tertiaries. Description : Carapace small, in lateral view ovate to elliptical and subreniform, highest at about middle. Height rather greater than one- half of length. Dorsal margin gently and evenly arched. Ventral margin practically straight. Anterior extremity subacute, somewhat truncated dorsally. Posterior extremity more evenly rounded. Convexity of valves moderate, nearly regular, but rising rather more steeply from dorsal margin than from ventral. Position of greatest thiekness of carapace located centrally. Valves subequal, left slightly overlapping right along ventral margin and the two extremities. Hinge somewhat thickened, occupying approximately central third of dorsal margin. In profile acute-ovate. In end view oval. Surface of valves delicately ornamented with elliptical riblets, reticulating to some extent, but generally concentric about apices of the two valves — i.e., the position of greatest thickness of carapace. Ornament somewhat resembling minute plicae or papillary ridges of human finger tip. Shell thin, fragile, ehitino- calcareous, and transparent to translucent. Dimensions of holotype: Length, 043 mm.; height, 0*25 mm.; approximate thickness of carapace, 0.2 mm. Remarks: A search of available literature has failed accurately to place this species generically. In ornamentation and general shape, however, it resembles some species of the recent genus Ilyodromus , and it is here tentatively referred to that genus. However, the carapace is not so compressed and is much smaller than any of the recent species of this genus, so it may be generically distinct. It resembles most closely Ilyodromus ellip\ticus Sars, but differs in having the dorsal margin more strongly arched, the ornament more conspicuous and concentric instead of generally longitudinal, and in its much smaller size. It also shows some resemblance to Ilyodromus obtusus Sars, but here again the differences are quite marked. Both these recent species of Ilyodromus have been recorded from New South Wales (Henry, 1923). This striking and easily recognised ostracod is moderately short- ranged, and a zone in The Narrows Tertiaries has been based on its proved vertical range of 115 feet — the Zone of Ilyodromus f concentricus. Through this interval the species has clearly been observed to increase gradually in abundance from very rare to very common, and, after reaching its acme, to decrease gradually until it becomes extinct. However, although it is very common in some of the samples from The Narrows, relatively few undamaged valves and complete carapaces have been found. This is apparently due to the very delicate and fragile nature of the shell and the fact that the valves are easily separated after death, since the hinge is edentulous. The outstanding characteristics of this species are the ornamentation and the small size. Some variation in outline within the species has been observed, which does not appear to be the result of crushing. While in most individuals the ventral margin 104 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. is either practically straight or slightly concave, in some it appears to be very slightly convex. Some variation in the ornament has also been noted. Although the riblets are generally wholly concentric about the apex of each valve, near the dorsal and ventral margin of some individuals they are arranged almost longitu- dinally. Their number and regularity also vary, and, if the number of reticulations joining them is great, the concentric arrangement may become rather confused. The size of all mature individuals of this species has been found to approximate to the dimensions given above for the holotype. The recent Ilyodromus is known to be a bottom dweller, creeping among the plants and in the mud of lake floors. It belongs to the subfamily Herpetocypridinae, all members of which are incapable of swimming in the adult state. Six species of the genus have been recorded from New South Wales, but only one species has been recorded as yet from Queensland (Henry, 1923) . The species has been named after the characteristic concentric ornamenta- tion of this little ostracod. Localities and Age : In The Narrows Tertiaries: Bores 1, 3, 4, 5, 6, 12, 13, 14 (see species occurrence charts), parishes of Targinie and Bundle, county of Deas Thompson, between Gladstone and Bockhampton. This species has a vertical range of only 115 feet. In the Petrie Series: Houghton’s bore, at about 45 feet, portion 24, parish of Warner, county of Stanley, near Lawnton, between Brisbane and Petrie. The fact that this species has been found at only the one locality in the Petrie Series suggests that it is a moderately short-ranged form. Probably Miocene. Genus Erpetocypris Brady and Norman, 1889. Genotype: Erpetocypris reptans (Baird), 1850, p. 160. Diagnosis: Carapace in lateral view elongate. Height less than, or approximately equal to, one-half of length. Dorsal margin variously arched. Ventral margin sinuated in front of middle to almost straight. Valves rather unequal, left usually slightly larger than right. Surface of valves generally smooth, to punctate. Range: Oligoeene to Becent. Erpetocypris aequalis Chapman, 1935. Plate VI, fig. 3. Holotype: F. 7851, University of Queensland Collection. Locality: Gully on Portions 118, 119, 120, Parish of Bundamba, County of Stanley, about 5 miles S. of Goodna, Queensland. Geological Horizon : Bedbank Plains Series. Description: Carapace medium-sized, in lateral view elongate oval to subreniform, highest slightly in front of middle. Height approximately equal to, or slightly less than, one-half of length. Dorsal margin evenly and gently arched. Ventral margin nearly straight to slightly concave in median region. Anterior extremity broadly rounded, meeting ventral margin with moderately sharp angle. Posterior extremity well, but not so broadly, rounded. Valves moderately convex only, to rather com- pressed. Convexity fairly regular, and position of greatest thickness located slightly behind middle. Valves equal, or very nearly so. In profile acute ovate, with anterior extremity somewhat compressed and posterior roundly inflated. In end view oval. Surface of valves polished, smooth except for few scattered punctations. Seven muscle scars OSTKACODS FROM SOME QUEENSLAND TERTIARY BASINS. 105 conspicuous, five centrally to subcentrally placed forming a rosette, and two slightly removed anteriorly and ventrally, arranged obliquely, one above the other, sloping ventrally. Rosette consisting of three, generally sub-oval, scars in transverse row, with row of two, generally sub-oval, scars slightly below. Muscle scars sometimes very close together, and some almost or completely coalescent. Two scars above rosette generally more elongate and narrower than others. Small accessory muscle scars sometimes present, in addition to fundamental seven. Shell of medium thickness, chitino-calcareous, generally whitish, and translucent to opaque. Dimensions of figured specimen from The Narrows: Length, 1*03 mm. ; height, 0*51 mm. ; approximate thickness of carapace, 045 mm. Remarks : In describing this species from the Redbank Plains Series in 1935, Chapman had at his disposal only one small sample of ostracod- bearing shale, obtained from a surface outcrop. In this rather weathered material he found the carapace valves of this species strongly calcified, and owing to their opacity he was apparently unable to see the muscle scars on the inside of the valves. Recent examination of additional samples from Redbank Plains, however, has resulted in the discovery of a number of these valves with translucent shells clearly showing the muscle scar pattern described above. The species, accordingly, has been found to be identical with that recognised in The Narrows material and, with the additional material available, a more complete description is given. E. aequalis compares very closely in shape with E. strigata (Muller), but differs from this recent European species, in having the extremities rather more broadly rounded, the carapace, particularly the anterior portion, more compressed, and in being approximately only half the size. No reference is made to muscle scars in the description of this recent species. As Chapman (1935, p. 68) has remarked, E. aequalis also 4 ‘nearly resembles E. glacialis Sars, of the European lakes and marshes, in its convex dorsum and evenly rounded extremities.” However, the valves, which are somewhat narrower and more compressed than those of E. glacialis, are highest slightly in front of the middle. E. aequalis is not as narrow or as elongate, although it has the same grouping of seven muscle scars, as Candonocypris assimilis Sars, an (H)erpetocyprid recorded and figured by Chapman (1919, p. 28) from the Pleistocene of Boneo Swamp, west of Cape Schanck, Victoria. The anterior extremity, moreover, is more broadly rounded than that of C. assimilis, and there are also other differences that separate it from this form. This species has been found to be common in some of The Narrows bore-core samples, and in all the ostracod-bearing shale examined from the Petrie Series and the Baffle Creek Tertiaries. Although very few complete, undamaged valves have been found, a large number of valves with shells broken to varying degrees have been available for microscopic study. The outstanding characteristics of this simple, smooth-shelled ostracod are the outline, equality and compressed nature of the valves, and the muscle scar pattern. There appears to be little variation in shape (apart from the effects of crushing), but variation in the number and arrangement of the muscle scars has been noted. In many individuals the two scars closest to the dorsal margin have been found to be almost coalescent and, in some cases, completely fused into one long scar. The addition of a very small muscle scar to the ventral end of 106 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. both transverse rows of the central rosette has also been observed in a number of individuals. Although not definitely observed, indications of the presence of a narrow marginal zone have been seen around the anterior extremity of several valves. It is possible, moreover, that the apparent absence of a marginal zone may be the result of brittleness of the shell, and consequent breaking, especially around the free edges of the valves. In all individuals the shell has been found to be fairly strongly calcified, whitish, and translucent to opaque. The generic name Erpetocypris is written as H erpetocypris by most zoologists, and this genus belongs to the subfamily Herpetocypridinae, the members of which, as the name indicates, are creepers. They are, in fact, incapable of swimming in the adult state, and are only found creeping among the plants, and crawling and burrowing in the mud on the bottom. Localities and Range: In The Narrows Tertiaries: Bores 1, 3, 4, 5, 6, 12, 13, 14 (see species occurrence charts), parishes of Targinie and Bundle, county of Deas Thompson, between Gladstone and Rockhampton. In the Petrie Series: Brecknell’s Bore, at somewhere between 60 and 178 feet,, subdivision 10 of portion 222, parish of Warner, county of Stanley, near Strathpine, between Brisbane and Petrie ; from old well on portion 190, parish of Warner, approximately two miles W. of Strath- pine; Houghton’s Bore, at about 45 feet, portion 24, parish of Warner, near Lawnton; from Simpson’s well, portion 186, parish of Nundah, county of Stanley, near Bald Hills, between Brisbane and Petrie. In the Baffle Creeh Tertiaries: From No. 2 Shaft, portion 30, parish of Warro, county of Flinders, near Lowmead, between Bundaberg and Gladstone; from various depths in the Lowmead No. 1 Bore, in the N.W. corner of the above portion. In the RedbanJc Plains Series: Gully on portions 118, 119, 120, parish of Bundamba, county of Stanley, approximately five miles S. of iGbodna, between Brisbane and Ipswich. This species is definitely a long-ranged form. Since it ranges through much of The Narrows material, and is common in all the Petrie Series, Baffle Creek, and Redbank Plains material examined, its range is probably Oligocene and Miocene.

OSTRACODS FROM SOME QUEENSLAND TERTIARY BASINS. 107 Dimensions of holotype : Length, 0*85 mm. ; height, 0-47 mm. ; approximate thickness of carapace, 0-4 mm. Remarks : A search of available literature has failed accurately to place this species generically. It resembles some species of Erpetocypris, however, in its rather compressed, smooth, moderately calcified valves, but it is not as elongate as most species of this genus, the ratio of maximum height to length having been found to average 56 :100. In certain species of Erpetocypris , however, the height is greater than half the length, and in E. fas data (Muller) the posterior extremity is as narrowly rounded as in this species. Nevertheless, Ef sub triangularis does not resemble very closely any of the described species of this genus. In shape, in fact, it is not unlike some species of the shallow- water marine genus, Pontocypris Sars, such as P. trigonalis Jones and Hinde. It differs from P. trigonalis , however, in having the height greater than half the length, and the anterior extremity more broadly rounded. Although this ostracod is not abundant in The Narrows material, it has been found to be fairly common in some of the samples examined, and it has also been found at one locality in the Petrie Series. Unfor- tunately, however, very few undamaged valves have been found, and in many cases all that remains is an internal cast with small fragments of the shell sometimes present. This is apparently due to the very brittle nature of the shell and the fact that it is not very thick. The outstanding characteristic of this smooth-shelled ostracod is the subtriangular outline with the semicircular anterior extremity and the contracted, acutely rounded, posterior extremity. The species has been named after the characteristic subtriangular shape of the carapace valves. Localities and Age: In The Narrows Tertiaries: Bores 1. 3, 4, 5, 6, 12, 13, 14 (see species occurrence charts), parishes of Targinie and Bundle, county of Deas Thompson, between Gladstone and Bockhampton. In the Petrie Series: Brecknell’s Bore, at somewhere between 60 and 178 feet, subdivision 10 of portion 222, parish of Warner, county of Stanley, near Strathpine, N. of Brisbane. This species does not appear to be a long- ranged form. Probably Miocene. Genus Stenocypris Sars, 1889. Genotype: Stenocypris malcolmsonii (Brady), 1886, p. 297. Diagnosis: Carapace in lateral view very narrow and elongate. Height considerably less than one-half of length, and nearly uniform. Dorsal margin very gently arched to almost straight. Ventral margin concave in median region. Anterior and posterior extremities rounded. Valves subequal, left slightly larger than right. Free edges smooth, inner duplicatures very broad, especially at the anterior extremity. In profile narrow oblong. Range: No Tertiary representative of this recent freshwater genus appears to have been recorded previously. Stenocypris lowmeadensis, sp. nov. Plate VI, fig. 8.

Geological Horizon : Baffle Creek Tertiaries. 108 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. Description: Carapace medium-sized, in lateral view narrowly elongate, highest at about or slightly behind middle. Height consider- ably less than one-half of length. Dorsal margin very gently arched. Ventral margin almost straight, to slightly concave in median region. Dorsal and ventral margins tending to become nearly parallel. Anterior extremity rather subacutely rounded, somewhat truncated dorsally. Posterior extremity more evenly rounded. Valves only moderately convex. Convexity fairly regular, with position of greatest thickness of carapace located slightly behind middle. Valves subequal, left slightly overlapping right along ventral margin and two extremities. In profile narrow oblong-ovate. Surface of valves polished, smooth, and unoma- mented. Shell of medium thickness, brittle, chitino-calcareous, white,, and translucent to opaque. Dimensions of holotype: Length, 1-76 mm.; height, 0-75 mm.; approximate thickness of carapace, 0-65 mm. Remarks: This ostracod compares fairly closely in both shape and size with certain species of S'lenocypris , but does not appear to be identical with any previously described form. It is apparent that this is the ostracod which Chapman in 1985 (p. 70) tentatively determined as cf. Paradox o stoma sp. Unfortunately, he had at his disposal only one small sample of ostracod-bearing shale from the Baffle Creek Tertiaries, and almost all the valves it contained were particularly badly crushed. Furthermore, since, in its outline, this ostracod does show some general resemblance to Paradoxostoma Fischer, it is perhaps not surprising that Chapman tentatively compared it with that littoral, marine genus. This species has been found to be quite common in the Baffle Creek ostracod-bearing shale, and it has also been recognised in the Redbank Plains material. Very few complete, undamaged valves have been found, apparently because of the brittleness of the shell and the fact that all the material has been very crushed. Although slight variations in outline have been observed, the ratio of height to length for most individuals has been found to be 41 :100. Some indication of a marginal zone traversed by radial pore canals has been observed around the anterior extremity of several valves. It is possible, moreover, that the apparent absence of a marginal zone from most valves may be the result of the brittle nature of the shell and consequent breaking, especially around the free edges of the valves. The species has been named after the township of Lowmead in the Baffle Creek Tertiaries near where it was found. One recent species of this genus has been recorded by Sars (1889) from lagoons near Rockhampton. Localities and Age: In the Baffle Creek Tertiaries: From No. 2 Shaft, portion 30, parish of Warro, county of Flinders, near Lowmead, between Bundaberg and Gladstone ; from various depths in the Lowmead No. 1 Bore, in the N.W. corner of the abovQ portion. In the Redbank Plains Series: Gully on portions 118, 119, 120, parish of Bundamba, county of Stanley, approximately 5 miles S. of Goodna, between Brisbane and Ipswich. Probably Oligocene.

Diagnosis: Carapace in lateral view elliptical to strongly ovate and tumid. Height generally greater than one-half of length. Dorsal margin broadly to sharply arched. Ventral margin straight to gently sinuate. Valves subequal, right generally the larger, with greatest overlap in median portion of ventral margin. Hinge short, occupying about one- third dorsal margin, simple, valves separated by narrow, knife-edged slit. Surface of valves smooth to pitted. Muscle scars slightly anteroventral of median point, each scar rather elongated. Range: Permian to Recent. Cypridopsis linearis, sp. nov. Plate VI, fig. 6. Holotype: Ft. 1981, Queensland Geological Survey Collection. Locality : Bore 1, at 135 feet, parish of Rundle, county Deas Thompson, between Gladstone and Rockhampton, Queensland. Geological Horizon : The Narrows Tertiaries. Description: Carapace medium-sized, in lateral view arcuately and broadly ovate, highest slightly behind middle. Height greater than one-half of length. Dorsal margin strongly arched. Ventral margin slightly concave in median region. Anterior extremity well rounded, but somewhat truncated dorsally. Posterior extremity broadly and more bluntly rounded. Valves moderately strongly convex with convexity almost regular. Position of greatest thickness of carapace located slightly behind middle. Valves unequal, right overlapping left anteriorly, ventrally and posteriorly. Surface of valves wholly orna- mented with small flattened tubercles, generally arranged in rows. Tubercles circular to oval in outline, contiguous, and approximately 0-02 to 0-03 mm. in diameter. Ornament somewhat draught-board-like in pattern. Rosette of five, subcentrally placed, muscle scars sometimes conspicuous. Shell thin, fragile, chitino-calcareous, and transparent to opaque. Dimensions of holotype : Length, 1-38 mm. ; height, 0*91 mm. ; approximate thickness of carapace, 0-75 mm. Remarks: The high, tumid shape of this ostracod is characteristic of the genus Cypridopsis. Although it compares closely in shape with certain species of this genus it appears to be distinct from all previously described species. It is not an abundant species in The Narrows material, but in some of the bore-core samples it has been found to be fairly common. Very few undamaged valves, however, have been found, and the above description is based in part on information obtained from fragments of the shell. The outstanding characteristic of this ostracod is the ornamentation. Some variation in outline within the species has been observed, which does not appear to be the result of crushing. While in most individuals the height nearly equals two-thirds of the length, in some cases it is only slightly greater than half the length. Variation in the ornament has also been noted. Although it generally shows a regular linear arrangement, in some individuals the ornament is much 110 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. less regular in its pattern and tends to resemble that of the well-known recent form Newnluvmia fenestrata King. In some individuals, also, the posterior overlap of the right valve appears to be greater than in others. Cypridopsis belongs to the sub-family Cypridopsinae, members of which are capable of swimming as well as creeping, and are most abundant in permanent, shallow, still waters. The species has been named after the ornament which generally is linearly tuberculate. Localities and Age: In The Narrows Tertiaries : Bores 1, 3, 4, 5, 6, 12, 13, 14 (see species occurrence charts), parishes of Targinie and Bundle, county of Deas Thompson, between Gladstone and Rockhamp- ton. This species has a proved vertical range of only 82 feet, but its actual range may be somewhat greater. Probably Miocene. Cypridopsis compressa Chapman, 1935. Plate VI, fig. 7. Holotypc: F. 7852, University of Queensland Collection. Locality: Gully on portions 118, 119, 120, parish of Bundamba, county of Stanley, about 5 miles S. of Goodna, S.E. Queensland. Geological Horizon: Redbank Plains Series. Descnption: Carapace medium-sized, in lateral view arcuately ovate to broadly reniform, highest slightly behind middle. Height greater than one-half of length. Dorsal margin strongly arched. Ventral margin concave in median region. Anterior extremity well rounded, but somewhat truncated dorsally. Posterior extremity more broadly and evenly rounded. Valves only moderately convex, with convexity fairly regular. Position of greatest thickness of carapace located slightly behind middle. Valves subequal, right slightly overlapping left anteriorly, ventrally, and posteriorly. In profile ovate, with anterior extremity compressed and posterior somewhat inflated. Surface of valves smooth and unornamented. Rosette of five muscle scars, placed slightly anteroventrally of midpoint, conspicuous. Shell thin, fragile, chitino- calcareous, and translucent to opaque. Dimensions of figured specimen from the Petrie Series: Length, 1-03 mm. ; height, 0-65 mm. ; approximate thickness of carapace, 0*5 mm. Remarks: In describing this species from the Redbank Plains Series in 1935, Chapman had at his disposal only one small sample of ostracod- bearing shale obtained from a surface outcrop. In this rather weathered material he found the carapace valves of this species strongly calcified, and, owing to their opacity, apparently he was unable to see muscle scars on any of the valves. Recent examination of additional samples, how- ever, has resulted in the discovery of a number of these valves with translucent shells clearly showing a rosette of five muscle scars. The species, accordingly, has been found to be identical with that recognised in the Petrie Series material, and, with the additional material available, a more complete description has been given. As Chapman (1935, p. 68) has remarked, Cypridopsis compressa “ bears a fairly close resemblance to Cypridopsis picta (Straus), a fresh- water form found in Norway, France, and Belgium.” It differs from OSTRACODS FROM SOME QUEENSLAND TERTIARY BASINS. Ill the latter species, however, in its greater height, broader anterior extremity, less inflated posterior, and more compressed carapace. The outstanding characteristics of this simple, smooth-shelled Cyprid are the outline of the valves, and the compressed nature of the carapace. There appears to be very little variation in the outline, and the ratio of height to length for most individuals has been found to be 62:100. Localities and Range: In the Petrie Series: Brecknell’s Bore, at somewhere between 60 and 178 feet, subdivision 10 of portion 222, parish of Warner, county of Stanley, near Strathpine, between Brisbane and Petrie; from old well on portion 190, parish of Warner, approximately two miles W. of Strathpine ; Houghton ’s Bore, at about 45 feet, portion 24, Parish of Warner, near Lawnton; from Simpson’s well, portion 186, parish of Nundah, county of Stanley, near Bald Hills. In the Baffle Creek Tertiaries: Prom No. 2 Shaft, portion 30, parish of Warro, county of Flinders, near Lowmead ; from various depths in the Lowmead No. 1 Bore, in the N.W. comer of the above portion. In the Redhank Plains Series: Gully on portions 118, 119, 120, parish of Bundamba, county of Stanley, near Goodna. Probably Oligocene and Miocene. Supplementary Note. Possibly two other distinct species have also been found in The Narrows material, and one in the Baffle Creek material, but, because of the badly crushed and very fragmentary nature of the valves, accurate identification and systematic description has not been possible. However, some taxonomic work has been carried out and, when better material becomes available, it is hoped to complete the description of these forms. PART III. CORRELATION OF DEPOSITS. A. The Narrows. General Aspects. An extensive diamond-drilling campaign has been carried out recently by the Queensland Department of Mines in The Narrows Tertiary basin, in connection with the possible exploitation of its oil shales. Ostracods were discovered in the bore-cores from this drilling by Mr. L. C. Ball, Chief Government Geologist, and subsequent examina- tion by the Queensland Geological Survey revealed their presence in much of the material. They were seen to persist sometimes through quite considerable thicknesses of the Tertiary shales, and it was thought that their palaeontological study might permit the correlation of the strata in the various bores. An attempt has, accordingly, been made to arrive at a satisfactory correlation, by a detailed micropalaeontological examination of the ostracods contained in collections of samples from eight boreholes on s 112 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. The Narrows. The samples examined were submitted by the Queensland Geological Survey, and were those selected from the regions where ostracods showed in quantity in the cores from Bores Nos. 1, 3, 4, 5, 6, 12, 13, and 14. The Tertiaries of The Narrows, centred 15 to 20 miles N. of Gladstone, occupy a narrow belt of country on both sides of the strait that separates Curtis Island from the mainland. The area on the mainland lies largely within the parish of Targinie, but extends to the S. just into the parish of Calliope, and to the N.W. into the parish of Bundle, while the part of the basin on Curtis Island lies within the parishes of Curtis and Monte Christo. All the above parishes are in the county of Deas Thompson, except that of Calliope, which is in the county of Clinton. Topographically the country is lowland, the surface in most parts being not more than 50 feet above sea level. Associated with the ostracods in these Tertiary shales, many of which are oil shales, gastropods belonging to the freshwater Planorbis group and fragmentary fish remains have been found. The association- of fossil fish with ostracods in the same strata is not unnatural, however, for recent zoological study has shown that they are an important source of food for fish today. Coprolites, which may have come from such freshwater reptiles as crocodiles or chelonians, also have been found in the bore-cores. Although the ostracods are very abundant in many of the samples they have generally been found to be crushed and broken. Some well- preserved individuals, nevertheless, have been found, but these are relatively uncommon, and usually occur in the better quality oil shales. With reference to habitat, in seems that, in most cases, The Narrows fossil ostracods could have no other origin than burial in situ. It has been observed, also, that while they are generally more abundant in the oil shales, they are quite common in some of the non-bituminous shales in the bore-cores. They are, however, rare and completely absent from some of the bituminous as well as the non-bituminous shales. Thus, it is clear that the ostracods themselves have not played the principal role in the formation of the oil shales as such. It is pertinent to mention the fact, however, that freshwater ostracods are known to favour a still, shallow water environment containing sufficient organic material for them to pursue their scavenging habits, and that in such an environment they may be found in vast swarms swimming near the surface, or creeping among the plants and in the mud of the lake floor. Zoological study has also shown that while these minute, bivalved crustaceans are omnivorous, they feed largely on decaying algal material. This is interesting, for many oil shales are now regarded as being primarily of algal origin. Accordingly, it is not unnatural to find ostracods abundant in these shales, since they apparently frequented such an environment as that in which the shales were formed. Their scarcity and complete absence from some of the oil shales, also, may possibly be correlated with the fact that recent freshwater ostracods are very rare in waters extremely high in organic material.

From a study of the above species occurrence charts it will be seen that the vertical range of Ilyodromus ? concentricus is approximately 115 feet. Although in Bores III, XIII, and XI Y the proved vertical range of this species is, respectively, only 61, 65, and 76 feet, it is apparent that these figures do not represent the complete range, since only widely-spaced and relatively small samples from these bore-cores were available for study. In all of the other bores the vertical range approximates to, but does not exceed, 115 feet. From this general persistence a broad zone, some 115 feet in thickness, has been set up. It has been called the Zone of Ilyodromus f concentricus. OSTRACODS FROM SOME QUEENSLAND TERTIARY BASINS. 115 I Text Fig. 1. Diagram of Bores at The Narrows, showing division of strata into zones, and correlations. 116 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. This Zone has been divided into three Snbzones, on the presence or absence of the other ostracod species. In the uppermost of these Subzones, which is approximately 20 feet in thickness, Cypris munduranensis, Ilyodromus ? concentricus, Cypridopsis linearis , and Erpetocypris? subtriangularis are present, while Cyprinotus punctatus and Erpetocypris aequalis are absent. This subzone has been called Subzone A. Underlying it is Subzone B, approximately 50 feet in thickness, and characterised by the presence of Cypris munduranensis, Ilyodromus? concent ricus, Cyprinotus punctatus , and Cypridopsis linearis , and the absence of Erpetocypris aequalis and Erpetocypris ? subtriangularis. This in turn is underlain by Subzone C, which is approximately 45 feet in thickness, and is characterised by the presence of Cypris munduranensis, Ilyodromus? concentricus , Cyprinotus punctatus, and Erpetocypris aequalis, and the absence of Cypridopsis linearis and Erpetocypris? sub triangularis. The Zone of Ilyodromus? concentricus is overlain by Zone I, from which Ilyodromus? concentricus, Cyprinotus punctatus, and Erpetocypris aequalis are absent, but in which Cypris munduranensis, Erpetocypris? subtriangularis, and Cypridopsis linearis are present. This zone is represented only in the samples submitted from Bores III, VI, XII, and XIV, and, because of the long ranges of the species present, it is not possible to divide it into subzones. It is at least 25 feet in thickness. The Zone of Ilyodromus? concentricus — or Zone II — is underlain by Zone III, in which Ilyodromus? concentricus is again absent. In this zone, which is at least 100 feet thick, Cypris munduranensis, Cyprinotus punctatus, and Erpetocypris aequalis are present, but Erpetocypris? subtriangularis, Cypridopsis linearis and Ilyodromus? concentricus are absent. Unfortunately, owing to the long ranges of the three species present, it has not been possible to divide this broad zone into subzones. From this division into zones, based on a study of the eight species occurrence charts, an approximate correlation of the strata in the portions of the various bores examined has been arrived at and the accompanying chart drawn up. For security reasons, no information concerning the exact location, relative position, and depth of these bores is at present available. Accordingly, the accompanying chart does not suggest any structural phenomena, but is one of zonation and correlation only. Although the relative position of the various bores has not officially been disclosed, however, they are known to be quite widely separated from one another, so that little, if any, structure could be deduced with safety from a correlation chart, even if the exact spacing were known. The surface elevation, respectively, at Bores I, III, IV, V, VI, XII, XIII, and XIV has officially been given as 45, 80, 25, 20, 5, 25, 12, and 25 feet, and this variation is shown on the correlation chart (Text Fig. 1). Discussion. In conclusion, it may be said that, although the ostracod species found in The Narrows Tertiary shales have proved somewhat disappoint- ing for purposes of close zonation, the recognition of various characteristic faunal assemblages has enabled the division into zones and approximate correlation of the strata in the various bores. OSTRACODS FROM SOME QUEENSLAND TERTIARY BASINS. 117 Taxonomic work on The Narrows ostracods and the referring of all the species to freshwater genera has also been important, since it indicates a lacustrine origin for these Tertiary shales. Furthermore, since freshwater fish, unionids, freshwater gastropods, and dicotyledonous leaves have also been recorded from this Tertiary basin, it now seems clear that the deposit is wholly a freshwater one. The study and identification of the various ostracods has provided certain information concerning the environmental conditions of deposition and origin of these ostracod-bearing shales. The presence and wide distribution of species which have been referred to the genera Erpetocypris, Ilyodromus and Cypridopsis suggest that the lake was shallow but probably of a permanent nature, that its floor was covered in part with mud, decayed vegetable matter and algae, and that the temperature of the water was probably very close to that found in similarly situated lakes today. Ostracods belonging to the genera Erpetocypris and Ilyodromus are found today only on the floors of shallow lakes and ponds, creeping among the plants, crawling and burrowing in the mud, and feeding mainly on algae. Furthermore, although Cypris, Cyprinotus and Cypridopsis are swimmers as well as creepers, they are known to occur most abundantly in still, shallow waters containing a moderate amount of organic material. Accordingly, it seems clear that The Narrows ostracod-bearing shales were laid down under the above environmental conditions and, since algal and other vegetable material was present in varying amounts, it is not surprising to find that many of these shales arc somewhat bituminous. Certain parts of this Tertiary lake, where the environment was particularly favourable, must have teemed with ostracods at the time. It might also be mentioned that, from the wide geographical and stratigraphical distribution of the ostracods in the basin, it would seem that these environmental conditions must have extended over a fairly considerable part of the lake, and existed intermittently at least for the time necessary for the deposition of several hundred feet of shale. It can be concluded, therefore, that the area was slowly subsiding. The fact that ostracods are scarce and completely absent from some of the shales passed through in boring, however, indicates that the above environmental conditions did not extend over the whole lake and throughout the entire period of deposition. One other environment, in which the amount of vegetable material was so great that the water was probably unsuitable for the presence of ostracods, is suggested by their absence from most of the higher-grade bituminous shales. Another environment, also, in which the amount of vegetable material was very small and ostracods were not abundant, is indicated by their scarcity in the coarser-grained, non-bituminous shales. Since freshwater gastropods have, on the other hand, been found to be more prevalent in these coarser-textured shales, they apparently favoured this environment. Finally, it must be admitted that the ostracods identified have not proved of very great value for the determination of the precise age of The Narrows Tertiaries. It is clear, however, that the fauna is fairly closely allied to the present-day one, since all the species described have been referred to living genera. It is possible, moreover, that some of the forms described may even be identical with living, but as yet undescribed species, or that some may be very closely related to such forms. Until the recent freshwater ostracod fauna of Queensland has been completely 118 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. described and detailed accounts of the structure of the carapace valves have been given, however, no very definite comparisons can be made. The presence of Cypris and Cypridopsis in the material, unfortunately, is of no value for purposes of age determination, since, although both these genera occur mainly in the Tertiary, their ranges extend back to the Jurassic and the Permian respectively. The genera Erpetocypris, llyodromus and Cyprinotus, however, are of some value. They are found only in the Tertiary and Recent and neither llyodromus nor Cyprinotus appears to have been previously recorded from the Tertiary. Erpetocypris , however, has been recorded from the Redbank Plains Series, which is probably of Oligocene age (Hills, 1934), and the known backward range of this genus was thereby extended considerably. Accordingly, it seems most unlikely that the age of The Narrows Tertiaries is pre-Oligocene. The presence of more recent genera than are found in the Redbank Plains Series, in fact, strongly suggests that the age of the beds is post-Oligocene. However, since none of The Narrows species seems to be identical with any of the described recent Australian forms, it is improbable that the shales are of Upper Tertiary age, as Pliocene and Pleistocene ostracod faunas generally are identical with recent ones. Moreover, it has already been shown that certain of The Narrows species were short-ranged, and some members of the fauna are definitely known to be extinct. However, since all but one of the species described have been found to be new, it is apparent that the species themselves cannot at present provide more precise information concerning the age of the strata. All the above information seems to indicate a probable Miocene age for The Narrows Tertiaries. This agrees with Hills’ recent determination (1943), from a study of the fossil fish, that “the age of the strata is probably Miocene.” When more taxonomic work has been carried out on Tertiary and Recent freshwater ostracods, however, and the geological ranges of the various genera and species have been accurately determined, a more precise and definite age determination may be possible. B. Petrie Series. General Aspects. As mentioned above, ostracods have been recorded by Ball (1932) and the present writer (1944) from four places in the Petrie Series, where they were found in shales brought up on putting down wells and bores. The Petrie Series, situated just N. of Brisbane, was named and originally described by Jones in 1927, and a more detailed, supplemen- tary account was given by the present writer in 1944. The series occupies a roughly circular area of some fifteen square miles centred about Strathpine (14 miles by rail N. of Brisbane) and is made up largely of shales, which owing to their soft nature seldom outcrop. As well as the occurrence of ostrocods, unionids, fossil fish and various plant remains have also been found in this Tertiary basin and, on palaeontological and lithological evidence, a provisional Miocene age has already been given to the series (Beasley, 1944). OSTRACODS FROM SOME QUEENSLAND TERTIARY BASINS. 119 Unfortunately, only a small collection of ostracod-bearing shale samples from the Petrie Series has been available for micropalae- ontological examination. A few small samples were obtained from Houghton’s bore at Lawnton, but most of this material was very much crushed and broken up by percussion drilling. Only two samples were found on the spoil heap of the old well on portion 190, parish of Warner and, although more material was collected from Simpson’s well, E. of Bald Hills, it had weathered practically to a soil and almost all the ostracods were present only as internal casts. Most of the material so far collected has, in fact, come from Brecknell’s bore at Strathpine, and this has provided the basis for the micropalaeontological work that lias been carried out. Quantitatively, however, the amount of ostracod- bearing shale available for study even from this bore was not great and, as the material had lain on the surface for several years, it had weathered and become still further broken up. Although much of the ostracod-bearing shale that has been collected is rich in ostracod remains, most of the valves are even more crushed and broken than those from The Narrows. An intensive microscopic search, however, has revealed a number of identifiable forms which have given some indication of the fauna and its affinities. In the collection of samples examined, the species present in order of abundance are: — Erpetocypris aequalis Chapman, 1935; Cypris munduranensis sp. nov. ; Cypridopsis compressa Chapman, 1935 ; Ilyodromusf concentricus sp. nov. ; Erpetocypris f subtriangularis, sp. nov. Discussion. Considered as a whole, the known ostracod fauna of this series shows a very close affinity with that described above from The Narrows Tertiaries. In fact, four of the five species identified — namely, Cypris munduranensis, Ilyodromusf concentricus, Erpetocypris aequalis , and Erpetocypris f subtriangularis — are found in The Narrows Tertiaries. In the presence of the other species, Cypridopsis compressa , as well as of Erpetocypris aequalis, how- ever, some affinity is shown with the fauna of the Redbank Plains Series described by Chapman in 1935. Although Erpetocypris aequalis and Cypridopsis compressa are common members of the Petrie Series fauna, it must be borne in mind that most simple, smooth-shelled Cyprids are long-ranged, so that the occurrence of these species needs not necessarily suggest approximately equivalent ages for the two series. In fact, the presence of these two ostracods in all the Petrie Series ostracod-bearing shale at present available suggests that they are moderately long-ranged forms. Accordingly, in evaluating the Petrie Series ostracods as a criterion of age, it is necessary to consider all members of the fauna. When this is done, there is definitely a much closer relationship between the Petrie Series and The Narrows ostracod faunas than between the former and that of the Redbank Plains Series. From this similarity in their ostracod faunas, and the fact that two of the species common to them are moderately short-ranged forms, it seems that the Petrie Series is equivalent in age to The Narrows Tertiaries. Since a probable Miocene age has already been suggested for The Narrows Tertiaries from a study of its ostracod fauna (see above), a probable Miocene age, then, can also be postulated for the Petrie Series. T 120 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. The recognition in the Petrie Series of so many of the same species as are found in The Narrows Tertiaries also suggests similar environ- mental conditions of deposition for the ostracod-bearing shales in both these Tertiary basins. (For a detailed account of these, see above.) Finally, the discovery of Ilyodromus? concentricus in the material from Houghton’s Bore near Lawnton has been of particular importance, since this species proved to have a vertical range of only 115 feet in The Narrows Tertiaries. Accordingly, the ostracod-bearing shale encoun- tered at about 45 feet in Houghton’s Bore may reasonably be correlated with some horizon within this 115-foot thickness. Furthermore, as this species has been found to be quite common in the Lawnton material, it may be stratigraphically equivalent to an horizon somewhere near the central part of the Zone of Ilyodromus? concentricus in The Narrows Tertiaries. It has, therefore, been possible to correlate a horizon in the Petrie Series at least approximately with an equivalent one in The Narrows Tertiaries. C. Baffle Creek. General Aspects. Immediately before and during the early part of the 1914-1918 war some consideration was given to the possibility of exploiting the oil shales of the Baffle Creek Tertiaries, and a number of shafts and a deep bore — the Lowmead No. 1 Bore — were put down in the southern part of the basin. A small collection of samples from some of these sinkings are now in the Museum of the Department of Geology, University of Queensland, and have recently been examined by the writer. All the shale samples in this small collection are somewhat bituminous in nature, but ostracods have not been found in all the specimens. In some, however, they have been found to be exceedingly abundant, and so closely packed that it is impossible to distinguish the individual outlines of the valves accurately. The Baffle Creek Tertiaries, situated in the upper part of the Baffle Creek valley, about midway between Bundaberg and Gladstone, are known to occupy a belt of country some eleven miles long and one to two miles wide, and to have a probable area of some thirty square miles. They extend from near Lowmead (48 miles N. of Bundaberg) almost to Colosseum (6 miles S. of Miriam Vale) on the main North Coast Bailway. As well as ostracods, Ball (1916, p. 15) has recorded indeterminable carbonised stem fragments, sponge gemmules, freshwater gastropods and chelonian remains from the Tertiary shales, and dicotyledonous leaves and unionids from the associated argillaceous sandstones in the basin. Ball (1914a, p. 21) has also stated that the Baffle Creek “shales closely resemble those of the Oxley district, near Brisbane, not only in lithological characters but in their fossil contents.” The ostracod-bearing shales examined are all from portion 30, parish of Warro, county of Flinders. A number of them are from various depths in the Lowmead No. 1 Bore, which was put down in the N.W. corner of portion 30, about a quarter of a mile from the railway and some two miles W.N.W. of Lowmead railway station. Several of the samples are from No. 2 Shaft, in the centre of portion 30, near the OSTRACODS FROM SOME QUEENSLAND TERTIARY BASINS. 121 bank of Marked Tree Creek, and the remainder are believed to have •come from outcropping shales also on this portion. Unfortunately, all the material that has been available for study is very badly crushed — even more so than that from The Narrows or the Petrie Series — and detailed micropalaeontological work has been particularly difficult. The species identified in the collection of samples, in order of their abundance, are : — Erpetocypris aequalis Chapman, 1935 ; Stenocypris lowmeadensis sp. nov. ; Cypridopsis compressa Chapman, 1935. Discussion. Prom our present knowledge, the ostracod fauna of the Baffle Creek Tertiaries seems to show a fairly close resemblance to that of the Redbank Plains Series. The known ostracod faunas of both these basins are smaller than that of either The Narrows Tertiaries or the Petrie Series, and in both the Baffle Creek Tertiaries and the Redbank Plains Series the forms Erpetocypris aequalis and Cypridopsis compressa are prominent. Since only three species have so far been identified from both of these basins, the similarity in their ostracod faunas is all the more marked. Although Erpetocypris aequalis and Cypridopsis compressa are known to be long-ranged forms, their common occurrence and the absence of several species found in The Narrows and the Petrie Series material show that the faunas of the Baffle Creek Tertiaries and the Redbank Plains Series are distinctly different from those of the above basins, and suggest a somewhat different geological age. It might also be mentioned that a recent examination of the Redbank Plains ostracod-bearing shale has resulted in the discovery of Stenocypris lowmeadensis in that material, so that this long, narrow ostracod also occurs in both the Baffle Creek Tertiaries and the Redbank Plains Series, but has not been found in The Narrows Tertiaries or the Petrie Series. Accordingly, from this similarity in their ostracod faunas, it seems likely that the Baffle Creek Tertiaries are approximately equivalent in age to the Redbank Plains Series. Although the ostracods themselves, in this case, do not give any information as to the exact age of these beds, it might be mentioned that Hills (1934), from a study of the fish remains, has concluded that the Redbank Plains Series is most probably of Oligocene age. It therefore seems that the Baffle Creek Tertiaries also are probably Oligocene in age. The referring to freshwater genera of the ostracods determined from the Baffle Creek Tertiaries has also further supported the concept that the basin is wholly a freshwater one. Finally, mention might be made of the fact that geographically the Baffle Creek Tertiaries and the Redbank Plains Series are centred about the same distance inland from the present coastline, while The Narrows Tertiaries and the Petrie Series, on the other hand, respectively are found adjoining and adjacent to the present coastline. PART IV. GENERAL CONCLUSIONS. Palaeontological work on the above ostracod faunas has clearly demonstrated their stratigraphical value. It has been possible to draw up a broad zonal correlation of The Narrows bores, and to correlate a number of the isolated Tertiary basins. The Narrows Tertiaries and the 122 PROCEEDINGS OF THE ROYAL SOCIETY OF QUEENSLAND. Petrie Series are considered as being most probably Miocene in age, and the Baffle Creek Tertiaries and the Redbank Plains Series as probably Oligocene. This has confirmed Hills’ conclusion (1943), from a study of the fish fauna of two of these basins (Redbank Plains and The Narrows), that the Tertiary deposits of Eastern Queensland are not all contemporaneous. The environmental conditions of deposition for these ostracod- bearing shales indicate that the lakes were largely shallow but probably of a permanent nature, that their floors were covered in part with mud, decayed vegetable matter and algae, that the temperature of the water was probably very close to that found in similarly situated lakes today, and that the lakes were all freshwater ones. Slow subsidence during deposition, also, is indicated by the thicknesses of ostracod-bearing shales that contain a shallow-water fauna. The absence of ostracods from some of the oil shales and their presence in non-bituminous shales show that they are not the principal contributor to the kerogen of the oil shales in these basins. Their common occurrence in them, however, is natural, since they favoured an environment rich in algal material such as that in which these oil shales were formed and, in most cases, they were apparently buried in situ. By partial decomposition of the soft parts of the animal, however, the ostracods may have contributed in some small measure to the formation of the oil shales. A partial animal origin has, in fact, been suggested by Ball (1914b, p. 74) for some of The Narrows and Baffle Creek oil shales, and by the present writer (1944, p. 98) for some of the Petrie Series oil shale. It is probable that the ostracods contained in the shales of some of the Tertiary basins, other than The Narrows, will also prove of value for zonal correlation purposes in the future. Since drilling operations will be necessary for the adequate study of all these basins, more sets of bore- cores should eventually become available and so enable attempts at zonation and correlation of the strata to be made. In conclusion, it may be said that, although the ostracods have not yet proved of very great value for the determination of the precise age of the various deposits, they have already given some indication of their probable ages. When more work has been carried out on Tertiary and Recent freshwater ostracods, and the geological ranges of the various genera and species have been accurately determined, more precise age determinations for some of these basins may be possible.

( Received 2 6th October , 1944; accepted for publication, 30 th October T 1944; issued separately, 29 th June, 1945.) This little Papuan orchid was discovered by the late Rev. Copland King near Ambasi, and was named in his honour by F. M. Bailey, who described it in Queensl. Agric. Journ. xvii (1906), 232, under the name Bulbophyllum Coplandii. The structure of the flower suggests that it would be better placed in Dendrobium. The length of the petals, the large spur, and the trilobate labellum with raised longitudinal lines or ridges, are all more characteristic of the latter genus than of Bulbophyl- lum. In the National Herbarium of New South Wales there are specimens in good condition sent by the Rev. P. C. Shaw from Ambasi in June 1906, and it is from these that a study of the plant has been made by the present writer. The labellum is very long and narrow, and in dried material its details are difficult to distinguish ; but after softening out a flower, the small lateral lobes could be unfolded, and the longitudinal ridges were revealed — one of them apparently continuing along the greater part of the middle lobe. The margins of the lobes are irregularly crenulate-crisped. The foot of the column is very long, corresponding with the length of the large spur, and the labellum is articulate with its apex by a very short claw. Plate VII. Dendrobium Copland] i (Bail.)

J The Royal Society of Queensland. Report of Council for 1943. To the Members of the Royal Society of Queensland. Your Council has pleasure in submitting the Annual Report of the Society for the year 1943. At Ordinary Meetings three addresses were given, two exhibit evenings, and two symposia held, while one meeting was devoted to films and a short address. Six original papers were accepted for publication in the Proceedings. The Chief Secretary’s Department has agreed to pay a £1 for £1 subsidy for printing on papers 1-8 published in Volume LIV. of the Proceedings and judged of value from a governmental point of view. The Council acknowledges this subsidy with gratitude. A large portion of the library, which had been stored in the basement as a precautionary measure during the previous year, was returned to the Royal Society room. A complete recataloguing of the library was undertaken, and this has been completed largely owing to the efforts of Mr. Pennington, whose assistance to the honorary librarian is warmly appreciated by the Council. During the year a deputation consisting of Prof. Richards, Mr. Perkins, and Prof. Bostock was received by the Premier, the Hon. F. A. Cooper, to discuss library facilities in post-war needs. Mr. Cooper gave an assurance that in the planning of a Central Library for the State, favourable consideration would be given to the housing therein of the library of the Royal Society. He also approved of financial assistance being given to the Society for the binding of journals to the extent of £50 os. There are 3 honorary life members, 4 life members, 3 correspond- ing members, 196 ordinary members, and 9 associate members in the Society. This year the Society has lost 2 members by death and 3 by resignation, while 11 have been elected to ordinary membership and 7 to associate membership. The Council would like to place on record its regret at the death of the late Mr. Henry Tryon. Mr. Tryon was an original member of the Society and the first Secretary. He was also one of the first honorary life members, and took an active interest in the affairs of the Society until his death. Attendance at Council meetings was as follows: — J. Bostock 7, D. H. K.
