BUCCINUM acutum. 
TAB. DLXVI. —Jig. 1. 
Spec. Char. Ovate,, elongated., pointed, smooth ; 
volutions convex ; aperture elongated, pointed 
above, nearly half as long as the shell. 
Somewhat resembling the following, but longer and 
more acute, besides being well distinguished by the sim- 
ple union of the whorls. 
This figure is taken from a large individual obtained 
in Queen’s County, Ireland, where the species occurs of 
various sizes in the Mountain Limestone. 
BUCCINUM imbricatum. 
TAB. DLXVI.— /g. 2. 
Spec. Char. Ovate pointed, obscurely striated ; 
whorls about six, their upper edges blunt, pro- 
duced and pressed against the spire ; aperture 
ovate, elongated, half the length of the shell. 
A nearly smooth shell, that has nothing remarkable in 
its general appearance; but the upper edge of each 
whorl is upon close examination found to embrace the 
preceding whorl in a peculiar manner.
