    SYDNEY Linnean Society of New South Wales, June 24.—The following papers were read:—Rough notes on the natural history of the Claremont Islands, by Gervase F. Mathew, R.N. Mr. Mathew gives an interesting account of the fauna and flora met with on these islands, in which he enumerates 23 species of birds and 20 species of Lepidoptera, of which 2 Lycaenæ are probably new. He also gives some notes on the habits of each species enumerated.—An afternoon among the butterflies of Thursday Island, by Gervase F. Mathew, R.N. Mr. Mathew gives an account of a few hours' ramble on Thursday Island, resulting in the capture of 48 species of diurnal butterflies. He gives a detailed description of the larva of Ornithoptera pronomus. He also makes brief mention of the flora and physical geography of the island.—New fishes from the Upper Murrum-bidgee district, by William Macleay, F.L. S. Two new fishes are here described, and two others, probably new, are noticed. The new ones are a species of Murrayia, from the Murrum-bidgee, near Yass, and a very blunt-headed species of Oligorus from the same locality. The two fishes alluded to as probably new are a species of Gadopsis from the Little River and a Galaxias from Yass River.—On a new Diplocrepis, by J. Douglas Ogilby. Mr. Ogilby describes, under the name of Diplocrepis costatus, a species differing considerably from D. puniceus of Richardson, and he points out that the fish is more nearly allied to the New Zealand genera, Diplocrepis and Trachelockismus, than to the Australian genera, Crepidogaster.—Jottings from the Biological Laboratory of Sydney University, by William A. Hasweli, M.A., B.Sc., Lecturer on Zoology and Comparative Anatomy.—On a destructive parasite infesting the oyster. Specimens of diseased oysters from the Hunter River beds were found to have their shells perforated and destroyed by a small boring annelid—Leucodore ciliata—which, by burrowing through the substance of the shell, causes the disintegration of the valves and the death of the oyster.—On some recent histological methods and their application to the teaching of practical histology.—On the minute structure of Polynoē.
