SCIENTIFIC SOCIETIES. 231 



The 18th contribution to the Mollusca of the 'Challenger' Expedition, 

 by the Eev. R. Boog Watson, was read, in which the author treats of the 

 family Tornatellidm, therein describing six new species of the genus Action. 



April 5. — Sir John Kirk, K.C.M.G., Vice-President, in the chair. 



Messrs. R. M. Barringtou, G. E. Comerford-Casey, F. V. Dickins, and 

 E. Cambridge Phillips were elected Fellows of the Society. 



There was exhibited for Mr. R. Morton Middleton a well-marked 

 example of wood showing the extensive ravages of the Isopod Ldmnoria 

 lignorum. The wood was from the pier-piles of West Hartlepool, where 

 the said crustacean's depredations are very destructive. 



Mr. F. W. Phillips read a communication in which he described a new 

 species of fresh-water Infusoriau allied to the genus Gerda, and which 

 provisionally is named G. caudata. 



Other papers read related solely to botanical subjects. — J. Murie. 



Zoological Society of London. 



March 20, 1883.— Prof. W. H. Flower, LL.D., F.R.S., President, in 

 the chair. 



Mr. Sclater called attention to the fact that a living specimen of 

 Macropus erubescens (a species originally described from a single specimen 

 living in the Society's Gardens) was in the Gardens of the Zoological and 

 Acclimatisation Society of Melbourne. 



Mr. Sclater laid before the meeting a set of the sheets of a new List of 

 British Birds, which had been prepared by a Committee of the British 

 Ornithologists' Union, and would shortly be published, and explained the 

 principles upon which it had been constructed. 



Prof. Huxley read a paper ou the oviduct of the Common Smelt, 

 Osmerus eperlanus, and took occasion to remark on the relations of the 

 Teleostean with the Ganoid Fishes. Prof. Huxley came to the conclusion 

 that the proposal to separate the Elasmobranchs, Ganoids, and Dipuoans 

 into a group, apart from and equivalent to the Teleosteaus, was inconsistent 

 with the plainest anatomical relations of these fishes. 



Mr. G. A. Boulenger read a paper containing the description of a new 

 species of Batrachian of the genus Bufo obtained at Yokohama, Japan, 

 during the Expedition of H. M.S. ' Challenger.' The author proposed to 

 describe it as Bufo for mosits. 



A communication was read by Mr. W. N. Parker containing some notes 

 ou the respiratory organs of Rhea macrorhyncha, and comparing these 

 organs with those of the Apteryx and Duck. 



April 3, 1883. — St. G. Mivart, F.R.S., Vice-President, in the chair. 

 The Secretary read some extracts from a letter he had received from 

 Mr. J. Sarbo in reference to the Gayal. The writer observed that Bos
