3. On FasTIGIELLA, A NEW GENUS OF SHELLS OF THE LAMARCKIAN 
Famity CananiFerRaA. By Lovett Reeve, Ese. 
The shell which I am about to describe, from the collection of 
Hugh Cuming, Esq., is of an entirely new form, differing generically 
as well as specifically from any of the class to which it belongs. It 
is of an elongated turreted growth, and may be said to partake in 
almost equal proportions of the characters of two genera somewhat 
removed from each other in the system, Turritella and Cerithium. 
As in Turritella, the shell is of a solid spirally-ribbed structure, with- 
out any indication of varices, a condition not to be found in Cerithium; 
whilst it possesses a character which excludes it from the family 
Turbinacea, in having a short umbilicated twisted canal, different 
from that of Cerithium, for the passage of an elevated fold of the 
mantle. At the base the shell is not much unlike some species of 
Buccinum, but it is remarkable for its elongated Turritella-like growth.
