been referred to the Genus Ampullaria, although they 
strongly resemble in their general habit, and are found 
in the same places as the fossil Naticse, such as A. acuta, 
and A. acuminata ; the want of a callus upon the colum- 
mellar lip, however distinguishes them all from the 
genuine Naticae, and it seems desirable to establish a 
distinct Generic name to arrange them under. On the 
other hand, the shell before us is so closely related to its 
companion, which may perhaps hereafter be separated 
from Turbo, that it appears advisable at present to keep 
them together as links that may serve to connect two 
apparently very distant Genera, the Turbo and Natica. 
We are of course totally unacquainted with the habits 
of these animals, but judge from their associates that 
they were inhabitants of Salt-water.
