It is, moreover, to all appearance the production of a carnivorous 
gasteropod, and more strictly referable to the Canaliferous tribe than 
the Cerithia, which, according to Deshayes, are vegetable-feeders, and 
partake in many instances of the freshwater habits of the Melanie. 
Unfortunately Mr. Cuming is not in possession of any information 
respecting the shell, either as touching the animal or its place of 
habitation, and it only remains to add the following description, with 
the hope that the attention of conchologists will be directed to a form 
which appears new and of much interest.

On the characters of this species it may be re- 
marked that there are ten forcibly developed keels 
to a whorl, all of which are concealed from the ob- 
server by the superposition of one whorl upon an- 
other excepting three, these being the most distant 
from each other.
