A paper was then read by Dr. John Lowe on the specific identity 

 of two forms of parasitic Crustacea, Lerneonema spratta, Sowerby, and 

 L. eucrasicholi, Turton, the only two of the genus which had been hitherto 

 recognised in Britain. A third species had been described by Dr. Salter 

 (Ann. Nat. Hist. 1850, p. 56) from the eye of the Herring, and to this he 

 gave the name of L. Bairdii ; but his figures show clearly that they were 

 drawn from imperfect specimens of L. spratta, which had been forcibly 

 removed from the fish's eye, leaving the head behind. The parasites in 

 question had been found only on the Sprat, Herring, and Anchovy. 



Zoological Society of London. 



February 17, 1891.— Prof. Flowee, C.B., LL.D., F.R.S., President, in 

 the chair. 



Mr. Edward Gerrard, jun., exhibited an extraordinarily large head of a 

 Koodoo Antelope, Strepsiceros kudu, which had been shot by Mr. F. C. 

 Selous near the river Macloutsie, Khama's Country, South Africa, in 

 May last. 



Mr. T. D. A. Cockerell exhibited and made remarks on a curious and 

 rather noteworthy monstrosity of a land-shell (Clausilia rugosa) with two 

 apertures. 



Mr. G. A. Boulenger exhibited and made remarks on the renewed left 

 pectoral fin of an African Lepidosiren (Protopterus annectans), from a living 

 specimen in the Society's Gardens. He also exhibited young specimens 

 and eggs of a South African Siluroid fish (Galeichthys feliceps), sent to him 

 by Mr. J. M. Leslie, of Port Elizabeth. They had been taken from the 

 mouth of the male parent, which carries its eggs in this extraordinary 

 manner. 



Prof. G. B. Howes read a paper on the probable existence of a Jacobson's 

 organ among the Crocodilia, and made observations upon the skeleton of 

 that organ in the Mammalia and upon the basimandibular elements in the 

 Vertebrata. 



Mr. R. H. Burne made some observations on the variation and 

 development of the Leporine sternum. 



Mr. Scott B. Wilson read a paper on Chasiempis, a genus of Musci- 

 capine birds peculiar to the Sandwich Islands. He described one of the 

 species inhabiting the island of Oahu as new, and named it Chasiempis 

 yayi, after Mr. F. Gay, of Kauai. The author further gave a key by 

 which the five species of this genus inhabiting the various islands may be 

 distinguished. Mr. Wilson also read the description of a new bird of the 

 genus Himatione, — based on a single specimen obtained on the island of 

 Maui, — naming it Himatione dolii, after Mr. S. B. Dole, of Honolulu. 



Mr. G. A. Boulenger read a paper on some British specimens of the
