OBITUARY NOTICE

CECIL THOMAS MADIGAN

Cecil Thomas Madigan, M.A., B.E., D.Sc., F.G.S., a leading Australian geologist and geographer, a member of this Society for the past 25 years, and a Past President, died at the early age of 57 years on 14 January 1947,

Curtailment of his span of life was doubtless the result of heart strain result- ing from exceptional exertions in the field of sport, exploration and war.

His earlier education was received at the Adelaide High School, Prince Alfred College and the University of Adelaide, where he graduated in Mining Engineering in 1910. As a Rhodes Scholar from South Australia, he then pro- ceeded to Magdalen College, Oxford, to continue with geological studies, which were, however, to be postponed, for late in 1911 he joined the Scientific Staff of the Australasian Antarctic Expedition of 1911-14.

Dr. Madigan’s record during more than two years in Antarctica was out- standing. It includes leadership of a sledging party which reconnoitred the ice plateau in winter time under record adverse climatic conditions. In the summer of 1912-13 he successfully led a sledge journey, charting a great length of new coast line of the territory thereafter known as King George Land. On return to winter quarters, he was selected to be in charge of all land operations pending the return of the Expedition Leader, who at that time had failed to return from a journey across the plateau ice.

His graphic account of the summer sledge journey forms a section of the popular story of the Expedition, published as “The Home of the Blizzard.” He was chiefly responsible for the meteorological record of the Cape Denison Station, which is published as an important section of the Expedition’s Scientific Reports issued from the Government Printing Office, Sydney.

On the advent of war when again in England in 1914, he joined the Royal Engineers and served throughout the whole period with rank of Captain. Later, having finally graduated at Oxford, he was appointed Assistant Government Geologist in the Soudan, This post he relinquished in 1922 to join the staff of the University of Adelaide.

With the outbreak of the Second World War, Dr. Madigan was appointed chief instructor in the School of Military Field Engineering (Liverpool, N.S.W.), attaining the rank of Lieut.-Colonel.

During his long term as lecturer in Geology, he found time to execute a number of important geological investigations dealing with problems relating to South Australia and to Central Australia, It is in the latter field that his work has received most recognition. His explorations in the MacDonnell Ranges and neighbourhood, and in the Simpson Desert, have established him as the leading authority on the Geography and Geology of Central Australia, For this work he was the recipient of wide recognition in scientific circles both in Australia and abroad. He is also well remembered for his zeal in furthering the good work of the Legacy Club and the University Graduates’ Association.

His published scientific works additional to those dealing with his Antarctic activities mentioned above are the following :—

Sensillae ciliated on distal half, with the sensillae bases nearer to each other than to PL and placed slightly anterior of line of PL. Eyes 2+2, on distinct ocular shields, the posterior eyes the smaller. Chelicerae not serrated on inner (dorsal) edge, with the usual small apical tricuspid cap forming the apical tooth, a small subapical dorsal tooth, and a small subapical ventral tooth. Galeal setae nude. Palpi stout, tibial claw bifurcate; seta on palpal femur 2-3-branched; on genu nude, on tibia only the ventral seta branched; tarsi short, with basal and subapical rods, and five or six ciliated setae, one of which is much stronger than the rest and over-reaches the tip of the tibial claw by the claw’s length.

AUSTRALIAN ACANTHOCEPHALA

By T. HARVEY JOHNSTON AND S.J.EDMONDS

Summary

Parasites of this species were found in the fish Callionymus calauropomus, caught in St. Vincent Gulf, South Australia. Five of six fish examined contained this parasite, and in four of them they were abundant. The intestines of all these fish contained crustacean material, especially amphipods and cyprids. The collections examined contained both males and females, the latter being slightly longer and broader than the males. In all the specimens examined the proboscis was protruded, but in no case was the copulatory bursa of the male everted.

The acck portion of the proboscis is very short, The srohoscis is armed with 25 hooks arranged in (en fongitudinal rows, consist- ina af fiye rows each of three hocks alternating will fwe rows each of two hooks (fy. 4.55. The lengths of the hooks, neasured along the curve from the pout ef exivasion to the tip of the hook, are shown in the following table -—

There are six cement glands which are elliptical to pyriform, In most cases they lic pressed closely together, The ducts of the six glands unite to [orm two lateral ducts, which join at their buses to form a U-shaped cement reservoir. Two well-developed diverticula project anteriorly from the bursa. The genital pare is terminal.

Female systeim—The general anatomy of the female system is shown in fig. 6. In a typical spectmen the nterine bell ig O-15 mm. long and is separated from the ulerus by a tiarcaw constriction, O't2 vu, in length. The uterus in the same specimen is 0-35 mm. long and 0: 07 mm. wide at the anterior end, Some of the female specimens contain floating ovaries, while the others bave both ovaries and eges. Mature eges, when mounted in methyl salicylate, measure 50 to 54 long and 13 to 14 wide, The polar extrusions of the middle shell are. well developed. A mamber of fennies bear a copulatory cap at their posterior extrenity,

Systematic position—We consider that this parasite belongs to the species Ifypoechinorhynchis aletcapis, deseribed by Yamaguti (1939, 325), from a Japanese fish, Our measurements agree very closely with those given by him. The hooks of our specimens, however, seem slightly longer, aiid the testes some- what smaller than in his material We regard Mypoccimorhynuchus as a yalid genus of the family Echinorhynenidae. The form of the probosets, as. well as the shape, number and arrangement of its hooks, are sttipeestive of those of Neocclitrorhynchus, but the characters of the cement glinds. are qanle different,

Although the parasites described hy Yamaguli were taken trom Alacups flinthus, he stated that a single immature Temale spechnen was collected from Cullionuyinus altigelis,

‘Thus species necurs in the mullet, Mugil cophalvs. Five of six fish examine irom Port Wihinga in March, 1939, were parasitised, in ome case heavily. The intestine of all the fish contained much plant debris with occasional mollises and small crustaceans. Two other fish taken at American River, Kangaroo istand, by Mr, TT. M, Coaper in January, 1945, also contained the same specics of parasite im considerable mumbers. In the stomach of these fish were gastropods and maumerous crustaceans (prawns, anmhlipods and copepods). Both imate and female specimens were collected. The worms ate long ard eylidrical, the ferale being longer and slightly broader than the male. Both sexes are devoid of hotly spines, Th 2 length of the inale ranges from 3-1 do 11-4 mm., aud the wmuniun width from 0-23 to O61 mm. The feimates are from ta 19*2 ton, Jong and from 0-22 to 0-69 mm. wide. The posterior hali or third of the female is twisted in most cases into two or three spirallike convolutions fig. 19). Thig may be duce to the fixing processes, All incastretictits were mare on anunalé cleared in nicthyt salicylate.

and 2°8 mm. long. Two lemnisci extended back as far as the posterior part of the proboscis sheath, The extreme anterior part of the body bore two sets of hooks, one group surrounding that part of the body adjacent to the proboscis, and the other group lying on the ventral side of the worm. The shape of the hooks is shown in hig. 24, The specimen was filled with unripe eggs which pre- verted the examination of the fernale complex. The largest of the eggs were 0:062 mm. long and 0-012 mm. broad. Three shells were seen, the middle bear- ing well-developed polar prolongations (fig, 25),

The specimen agreed in all essential details with the figures published by Lithe (1911, 44-46, fig, 58-63) and Meyer (1932, 47-48, fig. 23-25). The latter mentioned several kinds of fish as hosts of the parasite’ The species is now recorded for the first time from Australasian waters.
