BUCCINUM breve. 
TAB. DLXVI. —Jig. 3. 
Spec. Char. Nearly globose, tuberculated ; upper 
edges of the whorls wavy. 
Each whorl upon the spire, which has only three, is 
furnished with one row of obtuse knobs ; upon the last 
whorl are exposed three similar rows ; the upper edges 
of the whorls are undulated as they pass over a row 
of knobs which they conceal ; the aperture is nearly 
round with a short canal at its upper angle ; the lower 
edge is not notched, but only a little bent back, conse- 
quently it approaches that of the genus Turbo. 
BUCCINUM spinosum. 
TAB. DLXVI — -fig. 4. 
Spec. ChAr. Conical, elongated with a produced 
base ; a sharp furrow winds round each whorl, 
a row of large blunt spines is above it ; a row 
of smaller spines surrounds the base. 
When perfect, this must have been a handsome shell : 
the specimens we have now before us are however so 
mutilated, that it is with doubt we place it among the 
Buccina. 
The three species last described are from the Carbo- 
niferous Limestone (Mountain Limestone) of Bradley, 
near Newton Bushel, Devonshire, and are figured from 
specimens in the cabinet of H. T. De la Beche, Esq., 
who is at present engaged in preparing an account of the 
Torquay Limestones for the Geological Society.
