been referred to the Genus Ampullaria, although they 

 strongly resemble in their general habit, and are found 

 in the same places as the fossil Naticas, 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.
