50 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



observations on the history of the Australian Aboriginals. But it was 

 as a palseoconchologist that Etheridge's research work is of chief 

 interest to our Society. His first moUuscan paper was published in 

 1 873, and dealt with shells found in some Shell-marls near Edinburgh ; 

 then came a series of papers based on his studies of Carboniferous 

 Mollusca, which mostly appeared in the Geological Magazine and in 

 the Annals and Magazine of Natural History, including critical 

 notes on the Carboniferous Gastropoda and Pelecypoda figured in 

 Phillips' Geology of Yorkshire, besides recognizing the remains of 

 certain colour-bands of a twinned character on a small Naticiform 

 shell from the Carboniferous of Scotland. A little later he made 

 known some Unioniform shells from the Tasmanian Tertiaries. 

 Palaeozoic Opercula associated with small Gastropods next claimed 

 his attention, this being succeeded by an interesting account of the 

 British Carboniferous Chitonidse read before the Natural History 

 Society of Glasgow, 1881, while in the same year he delivered his 

 Presidential address to the Royal Physical Society of Edinburgh on 

 " The Palaeozoic Conchology of Scotland ". His chief Australian 

 memoirs included descriptions of the Cretaceous Shells of New 

 South Wales, embracing those found in the opalized deposits of 

 White Cliffs, besides which he wrote on the Palaeozoic and Cretaceous 

 Mollusca characterizing the deposits of the Bowen River region of 

 Northern Queensland. Separate memoirs were devoted to the 

 Pelecypod genus Eurydesma and " The Palaeopectens ", occurring 

 in the later Palaeozoic rocks of New South Wales. Much Molluscan 

 information was incorj^orated in the Geology and Palaeontology of 

 Queensland and New Guinea, published in 1892, a most compre- 

 hensive work consisting of nearly 800 pages of text and numerous 

 plates, which was written in conjunction with Dr. Robert Logan 

 Jack, a former Government Geologist of Queensland. Etheridge 

 also wrote a report on the Cretaceous Mollusca of Zululand. He 

 founded some new genera of Pelecypoda, including Unionella and 

 Deltopecten from the Palaeozoic beds of New South Wales, while those 

 from the Cretaceous rocks of the same colony, and Queensland, 

 include Tatella, Cyrenopsis, Fissilunula, Maccoyella, and 

 Pseudavicula. We must look to his Australian colleagues for a more 

 complete analysis of his works, which can be only gathered from 

 a survey of the scientific serial literature of Australasia. 



The memoirs and papers here briefly referred to sufl&ce, however, 

 to indicate that the author was possessed of indomitable energy and 

 unswerving perseverance, valuable attributes which enabled him 

 very largely to build up a considerable fame as one of the leading 

 palaeontologists of his time. Australia recognized these important 

 scientific services by awarding him the Clarke Memorial Medal of 

 the Royal Society of New South Wales in 1895, while the Australian 

 Association for the Advancement of Science bestowed upon him the 

 Mueller Memorial Medal in 1911.
