new to the Society's Collection. — Mr. Scia ter exhibited a skin of Ara 

 glauca, from Mr. Boucard's collection, obtained at Corrientes, and stated that 

 having compared it with the Ara now in the Gardens, purchased in June, 

 1860, and hitherto named A. glauca, he had come to the conclusion that the 

 living bird belonged to the allied form Ara leari. — Prof. Flower called 

 attention to the skull of the female Sealion, which had lately died at the South- 

 port Aquarium, and pointed out that it belonged to Otaria gillespii, and not, 

 as had been supposed, to Otaria stellen. — Mr. C. G. Danford exhibited 

 and made remarks on some remarkable antlers of Deer, which he had ob- 

 tained during his recent journey in Asia Minor. — Prof. Newton exhibited 

 skins of some rare species of birds obtained by Mr. Edward Newton, 

 C.M.Z.S., in Jamaica. — Mr. F. D. Godman exhibited and made re- 

 marks on a drawing of the Manatee by Mr. Wolf, taken from the specimen 

 lately living in the Westminster Aquarium. — Hans, Graf von Ber- 

 le psch, exhibited and made remarks on the skins of two varieties of the 

 Long-tailed Titmouse (Mecistura caudata), which occurred near Cassel, in 

 Germany , one of which appeared to be the same as the British form of this 

 bird. — Dr. J. Muri e read a paper on the Manatee, containing the results 

 of his examination of the specimen which was lately living in the West- 

 minster Aquarium. The peculiar attitudes assumed by the animal in life, 

 the great mobility of the upper lip , and the occasional use of the limbs in 

 feeding were noted. As regards the anatomy, the chief points dwelt on were 

 the shape of the brain and its suppressed convolutions. The vexed question 

 of the number of the cervical nerves and their distribution was also discus- 

 sed. — A communication was read from Mr. A. H. Garrod, on the brain 

 and on other points in the structure of the adult male Hippopotamus, which 

 was presented to the Society by the late Viceroy of Egypt in 1850, and 

 which died in the Society's gardens in March, 1878. — A second communi- 

 cation from Mr. Garrod contained a note on the mechanism of respiration, 

 as well as of the retraction of the head and limbs in certain Chelonia. — 

 Dr. Gwyn Jeffreys communicated the second part of his work on the Mol- 

 lusca of the »Lightning« and »Porcupine« Expeditions, embracing the families 

 from Anomiidae to Arcidae. The number of species noticed was 100, of which 

 4 were new to science, and 15 were hitherto unfigured. Particulars were 

 given of the geographical and geological distribution of all the species, and 

 their synonymy was discussed. Some species of Leda and Malletia were Sici- 

 lian fossils of the Pliocene formation, and had not been previously known as 

 recent or living. These species occurred at great depths, a fact which sho- 

 wed that the sea-bed in that part of the Mediterranean had been considerably 

 raised since the Tertiary epoch. — Mr. Edward R. Alston read a note on 

 the Acanthomas leucopus of Gray, showing that it does not belong to the 

 genus Acanthomys but to Mus proper. As the name leucopus is pre-occupied 

 in the latter genus, he proposed to call the species Mus terrae reginae. — Mr. 

 W. L. Distant read a paper on the African species of Lepidoptera of the 

 genus Papilio. A new species from Magila, East Africa, was described, 

 and the name of Papilio homimani was proposed for it. — A communication 

 was read from the Count T. Salvadori, C.M.Z.S., containing further 

 particulars of the new Pheasant from Western Sumatra which he had re- 

 cently described as Acomus inornatus. — Messrs. Godman and S al vin 

 gave an account of some hitherto unrecorded diurnal Lepidoptera, obtained 

 by the Rev. George Brown in Duke of York Island and New Ireland, to-
