long as the shell, and slightly curved towards the hidden spire; 

 the teeth of both the lips are nearlij similar, rather large, and dis- 

 tinct ; columella front deep, slightly concave, rib-striated. 

 Length -^, diameter r~^ of an inch. 



"When young the shell is thin, transparent', and polished ; the lip 

 gradually becomes incurved, and the surface has, before the outer 

 coat is deposited, a quantity of opaque white longitudinal lines, on 

 which the ribs are placed. 



I have been informed, on very good authority, that this shell 

 has been found on the Southern coast of Britain ; but I have not 

 had an opportunity of seeing the specimens. Payraudeau places 

 it in his list of Corsican shells, but he refers only to figures of 

 C. Europcra, although he distinctly describes the dorsal groove ; 

 and Blainville suspects that it is found in the Mediterranean Sea. 

 The variety is smaller and less ventricose ; the ribs are rugose 

 and end in a slight bead near the dorsal line, which is narrow and 

 deep. The back of the shell is mottled with reddish-brown dots, 

 which in some specimens are more crowded, where the spots are 

 placed in the other variety. It may probably prove a species. 



Lamarck and Defrance observe, that they have found at Turin 

 and Angers, a fossil shell which exactly agrees with this in form 

 and size.

 Bennett, Esq.^ F.L.S.^ Sfc. 



Having recently been engaged, in conjunction with Mr. Vigors, 

 in an examination of the Fishes contained in the collection of the 

 Zoological Society, we discovered among them many species 

 which have remained hitherto unnoticed by writers on Ichthyo- 

 logy. The more interesting of these I propose to describe in the 

 successive numbers of the Zoological Journal. On the present 

 occasion my attention will be directed to two new species of the
