casian Wild Goat and of two species of Deer. — Mr. E. E. Austen gave 

 an account of a journey undertaken by Mr. F. O. Pickard-Cambridge .and 

 the author up the Lower Amazons, on board Messrs. Siemens Bros. Cable 

 S.S. 'Faraday,' for the purpose of making zoological collections on behalf of 

 the British Museum. No terrestrial Mammals were met with, but observations 

 were made on the two species of freshwater Dolphins [Inia geoffroyensis and 

 Sotalia iucuxij or S. fluviatiUs)^ which are extremely abundant in the Lower 

 Amazons. Among the Birds, the only species of special interest collected 

 were a little Goatsucker from Manaos, referred provisionally to Nyctiprogne 

 leucopygia^ and a Woodpecker [Celeus ochraceus) . of which the British Museum 

 previously possessed but two specimens. The Reptiles and Amphibians met 

 with all belonged to well-known and widely distributed forms, and the chief 

 interest of the collections centred in the Invertebrates. Among these Mr. 

 Pickard-Cambridge made a large collection of Spiders, including an exten- 

 sive series of the large hairy Therephosidae, eleven species of which were 

 pronounced to be new. An interesting collection of the nests of some of 

 these forms was also obtained. Mr. Cambridge likewise secured several spe- 

 cimens oi Peripatus. Mr. Austen, who devoted himself chiefly to Insects, ob- 

 tained some 2500 specimens of different, orders, of which it was expected 

 that a fair proportion would prove to be new. Attention was drawn to some 

 interesting examples of mimicry. — Mr. P. Chalmers Mitchell, F.Z.S., 

 read a "Contribution to the Anatomy of the Hoatzin [Opisthocomus crisiatus).'''' 

 He stated that from the characters of the alimentary canal, the Hoatzin might 

 be placed either between the Sand-Grouse and the Pigeons,, or between the 

 Gallinae and the Cuculidae. He described some interesting individual 

 variations in the condition of the ambiens muscle, and referred to other 

 points in the muscular anatomy. — Mr. G. A. Boulenger, F.R.S., gave 

 an account of the occurrence of Tomistoma Schlegeli in the Malay Peninsula, 

 and added some remarks on the atlas and axis of the Crocodilians. — A 

 communication was read from Mr. W. Sc hau s containing notes on Walker's 

 American types of Lepidoptera in the University Museum, Oxford. — Mr. 

 Hamilton H. Druce, F.Z.S., read a paper entitled "Further Contributions 

 to our Knowledge of the Bornean Lycaenidae," in which he referred to about 

 40 species of this family not hitherto recorded from Borneo, A number of 

 these were new, and were now described by Mr. G. T. Bethune Baker and 

 the author. — Mr, F. G. Parsons read a paper on the anatomy of Petro- 

 gale xanthopus as compared with that of otjier Kangaroos. — Dr. J. Ander- 

 son, F.R.S., communicated on behalf of Miss M. E. Durham some notes 

 on the mode of swallowing eggs adopted by a South-African Snake, Dasy- 

 peltis scabra^ as observed in the specimens now living in the Society's Gar- 

 dens, and illustrated by a series of drawings. — Mr. F. O. Pick ard- Cam- 

 bridge read a paper on the Spiders of the family Aviculariidae taken during 

 the expedition up the Amazons previously described by Mr. Austen. — 

 Mr. G. A. Boulenger, F.R.S., read the description of a Gecko which 

 he proposed to refer to a new genus and species as Mimetozoon ßoweri, in 

 honour of Mr. Stanley Flower, who had obtained the specimen at Penang.
