his numerous and important memoirs on Fish and Reptiles generally ; and 

 Dr. August Weismann, Professor of Zoology, University of Freiburg, 

 Baden, whose Studies in the Theory of descent, and Embryological researches 

 on Insects and Hydroids &c are acknowledged worthy biological contri- 

 butions to science. — Mr. J. R. Willis Bund exhibited specimens in spirit 

 of the Rainbow Trout [Salmo irideus) which had been reared at the hatch- 

 eries of the Fish Culture Establishment, Delaford Park. He pointed out the 

 great diflference in size of members of the brood which were of the same 

 age having been reared from eggs of the same batch. He mentioned that 

 circumstances tended to show that it Avas a migratory fish ; hence as such 

 the value of its introduction as a supposed Stream trout would materially 

 be diminished. — A Report on the Alcyonaria and Gorgoniae of the Mergui 

 Archipelago by Stuart O. Ridley was read. A number of new forms 

 were described. From the present Collection the author believes that the 

 Alcyonarian fauna of the Burmese Coast is in no way behind that of the In- 

 dian Ocean generally, so far as known. It would seem to be rich in the soft, 

 fleshy Alcyonid section, e. g. Spongodes and Lobophyton &c; while the Gorgo- 

 niae are also fairly represented in new species and one new member of the 

 family Melithaeidae is now added viz. Mopsella plamtoca. — J. Murie.

30*^ March, 1887. — 1) Bacteriological. 2) Contributions towards a 

 knowledge of the Coleoptera of Australia. By A. Sydney Oil iff, F.E.S. 

 No. IV. Description of a new genus and species of Oedemeridae. Mr. Olliff 

 gives the name of Ithaca anthina to an insect captured by himself, about a 

 year ago, in Tasmania. It is chiefly remarkable for the enormous dilatation 

 of some of the joints of the antennae, and its spinous metasternum. — 



3) Second Note on Platyceps WilMnsonii and other fossils from Gosford. By 

 Professor Stephens, M.A., F.G.S. A brief account, with measurements, 

 is here given of two Labyrinthodont fossils, apparently belonging to the 

 genus Platyceps, and possibly to P. Wilkmsoììii, described last December. 

 Some notice is made of the occurrence with them of Ceratodus [fj , Belono- 

 siomus, &c., and of the conditions under Avhich they were entombed. — 



4) Additional evidence on Fossil Salishuria from Australia. By F. Ratte, 

 M.E. — 5) On an undescribed Shark from Port Jackson. By E. Pierson 

 Ramsay, F.R.S.E., &c., and J. Douglas-Ogilby. A detailed description, 

 with measurements, is here given of a well-known Port Jackson Shark, 

 generally known as the »Whaler«, and which has been hitherto looked upon 

 as Carcharias brachyuriis, Günth. It is named Carcharias mac7'urus. — 6) Con- 

 tinuation of list of Mr. Boyer-Bower's collection of Birds made in North 

 West Australia. By Dr. E. P. Ramsay, F.R.S.E., &c. — Mr. Norton ex- 

 hibited a specimen of one of the Myxomycètes, indentified by Mr. White- 

 legge as Stemonitis fusca, ox ferruginea, Ehrenb., found on the trunk of a tree 

 at Springwood. Mr. Wilkinson exhibited a selection from the Gosford Col- 

 lection of Fossils, now amounting to about 400 specimens, comprising a 

 number of new and remarkable forms of Fishes, and he pointed out the im- 

 portance of the evidence which is now accumulating in favour of the view 

 that the Hawkesbury formation is of Triassic age. Dr. Ramsay exhibited 

 an Egg of the Top-knot Pigeon Lopholaimus antar oticus , (Shaw), taken from
