general and historical introduction to this group of Nudibranchs, i.e., those which bear the branchiæ upon the dorsal surface, more or less surrounding the arms, and allusion was made to all the observations which had been made upon these animals. The second part consisted of definitions of the larger divisions and of the genera, with the enumeration, synonyms, and habitats, as far as possible, of every species hitherto recorded. In the last general list, viz., that by H. and A. Adams, but 163 forms were mentioned; this list included 457. The third part contained descriptions of forty-one hitherto undescribed species belonging to the genera Doris, Chromodoris, Hexabranchus, Acanthodoris, and Doridopsis.
A communication was read from the Count Salvadori, containing notes on some birds mentioned by Dr. Cabanis and Mr. Reichenow as collected in Papuasia and in the Moluccas during the voyage of the 'Gazelle.'
March 20, 1877.—Dr. E. Hamilton, Vice-President, in the chair.
Mr. Sclater called the attention of the meeting to an article in 'The Oriental Sporting Magazine' for May, 1876, in which it appeared that a two-horned Rhinoceros had been killed in February, 1876, at a place some twenty miles south of Comillah, in Tipperah. Mr. Sclater said that this was the third recorded occurrence of a two-horned Rhinoceros north of the Bay of Bengal.
Mr. Sclater also called attention to the fact that Mr. W. Jamrach had just imported a young living specimen of the Rhinoceros of the Bengal Sunderbunds, which was either Rhinoceros sondaicus or a very closely-allied form.
Mr. Sclater exhibited a small living Amphisbænian (Blanus cinereus), which had been accidentally brought to England in the roots of a hot-house plant from Port St. Mary, Spain, and was found at Clapham.
Messrs. Charles G. Danford and Edward R. Alston read a paper on the Mammals of Asia Minor, based principally on collections made by the former in that country. The list included one species of Bat, two of Insectivores, twenty of Carnivores, seven of Ungulates, and fourteen of Rodents. Spermophilus xanthoprymnus, Benn., was re-described, and the name Mus mystacinus was proposed for a new species of Field Mouse.
Mr. A.G. Butler read a paper on the Myriopoda obtained by the Rev. G. Brown in Duke of York Island. The species sent home were two in number, both of them allied to but distinct from previously described species. Mr. Butler proposed to designate them as Heterostoma Brownii and Spirobolus cinctifes.
A communication was read from the Rev. O.P. Cambridge, in which he gave the description of some Spiders collected by the Rev. G. Brown in Duke of York Island, New Britain, and New Ireland. Two of these
