p. Shell of c. In spirits. 
f. ? Shell dry. (Probably of this species.) 
D’Orbigny, in his description, says the shell is without any 
lateral ridges or thickening, but his specific character is ( lateribus 
incrassatis) . Both our specimens have three or four small cups, 
forming a single line on the angles of the buccal membrane ; and 
they show that the rings, on which M. D’Orbigny appears to place 
much reliance, change their character with the age of the spe- 
cimens. 
** Buccal Membrane without any Cups. 
| Shell very thin , not thichened on the Edges .
