specimen of the Decapod Crustacean Alpheus megacheles, obtained by Mr. 

 Spencer at Herrn, Channel Islands. — Mr. Martin Jacoby communicated 

 the second portion of his paper on the Phytophagous Coleoptera of Japan 

 obtained by Mr. George Lewis during his second journey, 1880 — 1881. 

 The present part treated of the Halticinae and Galerucinae of Mr. Lewis's 

 collection. — Mr. A. G. Butler read a paper containing an account of two 

 collections of Lepidoptera recently received from Somali-land. Mr. Butler 

 considered that the Lepidopterous fauna of Somali-land was essentially Ara- 

 bian in character. — Mr. L. R. Lydekker, F.Z.S., described a last upper 

 molar of a Mastodon, which had been obtained by Mr. A. H. Everett^ 

 C.M.Z.S., in Borneo, and referred it to a small race oi M. latìdens, pre- 

 viously known only from the Pliocene Siwaliks of India and Burma. The 

 specimen was of much interest, as increasing our knowledge of the eastern 

 range of the Siwalik mammals. — Mr. W. T. Blanford. F.R.S., read a 

 monograph of the genus Paradoxurus. After a critical examination of a large 

 series of specimens, Mr. Blanford came to the conclusion that it would be 

 necessary to reduce the numerous so-called species of this genus to about 

 ten well-marked forms. — Mr. W. T. Blanford, on behalf of Mr. J. A. 

 Murray, read a paper containing the description of a new species of Mtis 

 from Sind, proposed to be called Mus Gleadowi. — Mr. F. E. Bed dard, 

 F.Z.S., read an account of the specific characters and structure of some New- 

 Zealand Earthworms of the genus Acanthodrilus. — P. L. Sclater, Secre- 

 tary.

5th November 1885. — Sir J. Lubbock, Pres, in the Chair. — Mr. 

 A. E. Heath showed a Golden Eagle in its characteristic plumage of the 

 2nd year. — The first part of an exhaustive Monograph on Recent Brachio- 

 poda, accompanied by illustrations, by the late Dr. Thomas Davidson was 

 read by the Secretary. In this part of his Contribution, the author reviews 

 the labours of his predecessors in the field, both with regard to the shell, to 

 the anatomy of the adult, and to the embryology. As regards the perplexing 

 question of affinities he remarks : — »Now although I do not admit the Bra- 

 chiopoda to be Worms, they may as well as the Mollusca and some other 

 groTîps of invertebrates, have originally diverged from an ancestral vermi- 

 form stem, such as the remarkable worm-like mollusk Neomenia would de- 

 note. He lays stress on the Brachiopodous individual being the product of 

 a single ovum and not giving rise to others by gemmation. He considers 

 that the shell, the palliai lobes, the intestine, the nerves, and the atrial 

 system, afford characters amply sufficient to define the Class. The greatest 

 ■depth at which a living species has been found alive, has been 2990 fathoms. 

 As to Classification he groups the recent species into two great divisions : 

 — I. Anthropomata (Owen = Clistenterata (King) , II. Lypomata (Owen,- 

 = Tretenterata (King). The Anthropomata he groups in 3 families : — 

 1st Fam. Terebratulacea with 7 subfamilies and 13 genera and subgenera, 

 70 species, and 21 uncertain species: — 2nd Fam. Thecideidae with 1 genus 

 and 2 species : 3rd Fam. Rhynchonellidce, 1 genus, 1 subgenus and 8 species. 

 The Lypomata he also groups into 3 families, 1st Fam. Craniidee with 1 ge- 

 nus and 4 species, 5 genera and subgenera, 23 species and 7 uncertain spe- 

 cies: — 2nd Fam. Discinidae with 1 genus, 1 subgenus und 8 species: —
