it not a very thick columellar lip and two rows of tuber- 
cles around the edges of the whorls. 
Named in MSS. by the Rev. G. R. Leathes, to whom 
also we are obliged for the discrimination of the species. 
It is more rare than the B. granulatum among Crag in 
the same localities. 
BUCC1NUM labiosum. 
TAB. CCCCLXXVIL— ^g. 3. 
Spec. Char. Ovate,, pointed, straightish on the 
sides, transversely sulcated ; columellar lip 
broad and relieved ; aperture oblong pointed 
above. 
A very distinct small shell ; the volutions are rather 
flattened on their sides, especially the last one ; the sulci 
are ten or twelve upon each whorl, and rather broad ; 
the whorls are slightly separated from each other at 
their upper edges. 
Discovered and named by the same gentleman as the 
last, along with which it is found.

This Figure represents a less elongated variety of Buc- 
cinum sulcatum, that might easily be taken for a spe- 
cies : it is smoothened by wear, but we are assured by 
Mr. Leathes, who sent it us, that it is the same species 
as our fig. 2 of Tab. 375.
