 Mr. Cuming has shown me a young shell which he brought from 

 the mountains of Tanhay in the Isle of Negros, where it was taken 

 on the leaves of trees. I thought at first that it might be the young 

 of Helix Harfordii, but the sculpture of the shell and the quality of 

 the epidermis correspond so closely with those of the adult shell 

 just described, that though there is some difficulty arising from the 

 capture of the two shells in different islands, I am inclined to be of 

 opinion that it is probably the young of Helix cretata.

Var. a. Albens brunneo et nigi-o pulchemme fasciata. 



Of the whitish class of variety (a) there are variations without 

 end, according as the bands are more or less present or absent. In 

 some the whitish epidermis is only relieved by a brown sutural line 

 and a deep submedial band on the body-whorl, which is more or less 

 interrupted and ribanded with white and light brown towards the 

 base. 



Var. b. Brunnea albido et nigricante concinne fasciata. 



The same maybe said of this section, which varies as much as var. 

 0. This imperfect description was drawn from six of each class ; 

 but at least treble the number of each would be requisite to give a 

 correct idea of the infinite variations of this beautiful species.

A collection of birds from Newfoundland, presented by E. Moore, 

 Esq., was exhibited : it consists of specimens, in different states of 

 plumage, of the Willow Ptarmigan {Tetrao Saliceti), a specimen of 

 the Pin-tailed Duck {Bafila caudacuta) , the American Teal {Querque- 

 dula Americana), and the Black-backed Gull (Larus marinus). The 

 collection also contains a foetal Esquimaux preserved in spirit. 



A paper by G. B. Sowerby, Esq., was read, in which the author 

 proceeds with his descrij)tions of the new species of shells collected 

 by H. Cuming, Esq., in the Philippine Islands. The following 

 species were described and exhibited : — 



Helix matruelis. Hel. testd depressiusculo-subglobosd , tenuius- 

 ctild, Icevi, castaned, epidermide opacd, pallescente, hydrophand 

 indutd ; spird subdepressd, anfractibus quutuor subrotundatis, til-
