SCIENTIFIC SOCIETIES. 153 



Peru. The collections made in the years 1890-93 had been transmitted to 

 the Branicky Museum of Warsaw, and contained examples of 295 species 

 and subspecies, of which an account was given in the present paper. Five 

 species and twenty-two subspecies were described as new. 



Dr. David Sharp, on behalf of the Committee for investigating the flora 

 and fauna of the West India Islands, communicated a paper on West Indian 

 terrestrial Isopod Crustaceans prepared by M. Adrien Dollfus. 



March 17th.— Prof. G. B. Howes, F.L.S., F.Z.S., in the chair. 



Mr. Sclater called the attention of the meeting to the prospectus of the 

 great work of the German Zoological Society, to be called ' Das Tierreich,' 

 spoken of at the last meeting, and gave some particulars as to the mode in 

 which the plan was intended to be carried out. He also called attention 

 to the appointment of a Committee on Zoological Nomenclature at the 

 International Zoological Congress held at Leyden last year. 



A communication was read from Lieut.-Col. C. T. Bingham, containing 

 a contribution to the knowledge of the hymenopterous fauna of Ceylon. The 

 paper was founded mainly on the collections made in that island by Col. 

 Yerbury, R.A., and Mr. E. E. Green, and dealt only with the Monotrochous 

 Hymenoptera, of which 335 species were recorded. Of these seven were 

 now described as new. The author observed that this number was far less 

 than what must actually occur in an island with so varied a climate and 

 flora. Most of the species, as was to be expected, likewise occurred in 

 India. 



A communication was read from Mr. Edward T. Browne on British 

 Hydroids and Medusae. This paper contained descriptions of the early 

 stages, and notes on twenty species of Medusae, of which examples had been 

 collected at Plymouth, and in Valencia Harbour on the west coast of Ireland. 

 It also contained a revision of the synonyms of the species and an account 

 of their distribution. Notes on the hydroids connected with some of the 

 species were added. 



Mr. A. Smith Woodward read a paper on some extinct fishes of the 

 Teleostean family Gonorhynchida. He described a new specimen of Noto- 

 goneus osculus from the Eocene (Green River Shales) of Wyoming, U.S.A., 

 confirming Cope's determination of this fish as a member of the family 

 Gonorhynchida. He also pointed out that the so-called Sphenolepis 

 squamosseus and S. cuvieri, imperfectly described by Agassiz from the 

 Eocene of France, are generally identical with Notogoneus. In proof of 

 this identification, he gave an account of new specimens in the British 

 Museum. The Gonorhynchida were thus shown to have comprised fresh- 

 water fishes in the early Tertiary period both in Europe and North 

 America — P. L. Sclater, Secretary.
