118 THE ZOOLOGIST. 



heretofore has only been recognised from young specimens. Of Batrachia 

 two specimens were obtained, viz. Rana esculenta and Bufo viridis, and on 

 the latter a Leech, Aulostoma gulo, was found. Circumstances prevented 

 more than seven species of fish from being procured ; these proved to belong 

 to six genera : two of these species are new to science. Schizothorax inter- 

 medins is interesting, as it was found by GrifiBth in the Cabul river, an affluent 

 of the Indus. In the great eastern drainage of East Turkestan it was found 

 at Youngsi-Hirsar by the second Yarkand Mission. The new species of 

 Schizothorax was only met with in the Hari-rud and its tributaries. Over 

 one hundred species of insects were collected, of which twenty prove 

 new. The greater number of them are typical of the Arabian, North 

 African, and Mediterranean faunas; a few only have Indian and Central 

 Asian affinities. It was observed that the Lepidoptera generally appeared 

 at irregular intervals, only when there was perfect stillness in the air, and 

 then in limited numbers. 



February 17. 1887. — The only zoological paper read at this meeting 

 was by Dr. Hoek, of Leiden, " On Dichelaspis pellucida, Darwin, from the 

 scales of an Hydrophid obtained at the Mergui Archipelago by Dr. John 

 Anderson." As far as the author's knowledge goes, this species of Cirri- 

 pede has not been observed since Darwin published his description from 

 specimens procured in the Indian Ocean and also from a sea-snake. It 

 seems that although somewhat larger in dimensions, and with other slight 

 variations which may be due to difference of age, there can be little doubt 

 of the identity of the Mergui specimens with Darwin's D. pellucida {Monogr. 

 Cirriped. i. p. 125). — J. Mueie.

February 1, 1887.— Dr. St. George Mivart, f .R.S., Vice-President, 

 in the chair. 



Mr. F. Day exhibited and made remarks on a hybrid fish supposed 

 to be between the Pilchard and the Herring, and a specimen of Salmo 

 purpuratus reared in this country. 



Mr. W. L. Sclater exhibited and made remarks upon some specimens 

 of a species of Peripatus which he had obtained in British Guiana during 

 a recent visit to that country, and added some general observations on the 

 distribution and affinities of this singular form of Arthropod. 



Mr A. Thomson read a report on the insects bred in the Society's Insect 

 House during the past season, and exhibited the insects referred to. 



A communication was read from Dr. B. C. A. Windle, containing an 

 account of the anatomy of Hydromys chrysogaster. 



Mr. Martin Jacoby read a paper containing an account of the Pliyto-
