on board the s. s. ' Ottoman ' in October last, during the voyage from Boston 

 to Liverpool, as mentioned at a former meeting (November 7th). 



Mr. A. Rolfe gave an abstract of a paper entitled "A Revision of the 

 genus Vanilla," in which some fifty species were enumerated, seventeen of 

 which were described as new, though five of them had been previously 

 confused with older forms. The paper was illustrated by a series of 

 carefully-made drawings. 



Mr. E. S. Goodrich communicated a Report on the collection of Cephalo- 

 poda in the Calcutta Museum. He explained that this collection had been 

 forwarded from Calcutta to Prof. Ray Lankester, at whose request he had 

 undertaken to examine and report upon the species. It contained 162 

 specimens, almost all of which were collected in the Indian seas from 

 the Persian Gulf to the coast of Australia, during the cruise of H.M.S. 

 * Investigator.' Fifteen genera were represented, and several new species 

 were described belonging to the genera Cheiroteuthis, Histiopsis, Abralia, 

 Voliolus, and Faonius. The paper was illustrated by original drawings.

December 3rd, 1895.— Sir W. rl. Flower, K.C.B., LL.D., F.R.S., 

 President, in the chair. 



The Secretary read a report on the additions that had been made to the 

 Society's Menagerie during the months of October and November, 1895, 

 and called attentiou to the acquisition of a specimen of the Wild Goat of 

 the island of Giura, in the iEgean Sea (Capra dorcas). 



Mr. Tegetmeier exhibited a Crab with a supernumerary claw. 



A communication was read from Dr. G. S. Brady, containing a supple- 

 mentary report on the Crustaceans of the group Myodocopa obtained during 

 the ' Challenger' Expedition, to which were added notes on other new or 

 imperfectly known species of this group. 



Mr. F. E. Beddard communicated some points in the anatomy of Pipa 

 americana and on the diaphragm and the muscular anatomy of Xenopus, 

 with remarks on the affiuities of these two anomalous Batrachians, which 

 he considered as correctly placed together in the system. 



Mr. W. Bateson gave an account of the colour variations of a variable 

 Beetle of the family Chrysomelidce (Goniocteiia variabilis) statistically 

 examined. It was shown that the individuals are chiefly red spotted with 

 black, or else greenish grey striped with black. Intermediate forms occurred, 

 but were less common than the type-varieties. These facts illustrated the 

 phenomenon of organic stability* 



A communication from Mr. R. Lydekker contained remarks on the 

 affinities of the so-called extinct Giant Dormouse of Malta, to the effect that 

 this extinct rodent did not belong to the Myoxida, but rather to the Sciuridce,
