A letter was read from Mr. E. L.Layard respecting a specimen of Schomi- 

 cola platyura received by the British Museum from the late Mr. Cuming. 



Prof. F. Jeffrey Bell exhibited some examples of Limnaus truncatulus, 

 lately discovered to be the chief host of the larvae of the Sheep-fluke. 



Prof. Flower exhibited ami made remarks upon the skull of a young 

 Chimpanzee from Lado. in the Soudan, sent to him by Dr. Emiu Bey, 

 which exhibited the deformity called " Acrocephaly," associated with the 

 premature closure of the fronto-parietal structure. 



Mr. H. E. Dresser exhibited and made remarks on specimens of 

 Melittophagus Boehmi, Reichenow, and Mergus Dresseri, Shelley, which he 

 showed to be identical. 



A communication was read from Mr. W. A. Forbes containing some 

 supplementary notes on the anatomy of the Chinese Water-deer, Hydro- 

 potes biennis. 



A communication was read from the Rev. L. Baron, containing notes 

 on the habits of the Aye-Aye of Madagascar in its native state. 



Mr. G. E. Dobson read a paper on the natural position of the family 

 Dipodidce, which he maintained to be with the Hystricine, and not, as 

 generally supposed, with the Murine Rodents, and to be most nearly allied 

 to the ChinchiUidcB. 



Prof. F. Jeffrey Bell read a paper on the genus Psoitis, relating its 

 literary history, and giving an enumeration of the described species. 

 Attention was directed to the extensive distribution of P. Fabricii, and to 

 the variations during growth. After the description of other known forms, 

 two new species (/'. Peronti and P. ambvlata) were described; for the latter 

 a new subgenus was suggested, and the genus itself was divided into three 

 subgeneric groups. 



A second paper from Prof. Bell contained an account of a Crinoid from 

 the Straits of Magellan, obtained by Dr. Coppinger during the voyage of 

 H.M.S. ' Alert,' which was referred to a new variety of Antedon Eschrichti 

 of the Arctic Seas. 



Mr. W. H. Neale read some notes on the Natural History of Franz- 

 Josef Land, as observed in 1881-82 during the stay of the ■ Eira' expedition 

 in that land. 



Dr. Gwyn Jeffreys read the fifth part of his list of the Mollusca procured 

 during the expeditious of H.M.S. 'Lightning' and ' Porcupine.' This part, 

 which embraced the species from the Solenoconchia to the Calyptraidce, 

 comprised sixty-nine species, of which twenty-two were now for the first 

 time described or figured. The geographical, hydrographical, aud geological 

 range of all these species was given, as in his former papers ; and the author 

 especially noticed the points of agreement between the deep-water Mollusca 

 from the American and European expeditions. — P. L. Sclater, Secretary.
