TAB. DCXIV — -fig. 2. 
Spec. Char. Ovate-turbinate, ventricose, trans- 
versely furrowed towards the pointed base ; 
upper part of the last whorl more or less keel- 
shaped; spire short, distinct from the last whorl, 
imperfectly ribbed, each rib divided into several 
spines which are gradually lost towards the last 
whorl ; columella with one large and several 
small plaits ; aperture much elongated, 8-angled ; 
the inner lip tumid above 
Syn. Voluta Labrella, Lam . Hist. Nat. vol. 7. 858.

The French specimens of this species are generally much 
more carinated than the English ones, but even in them the 
keel varies in sharpness: the difference between young shells 
from the two countries is very slight. In the English full- 
grown shell the keel is broad, rounded and not distinct 
from the body of the whorl, which is nearly even and smooth 
except toward the base. The swelled inner lip appears 
to be an important character. 
Specimens of this shell in various stages of grow th have 
been lately collected in Bracklesham Bay, by J. S. Bower- 
bank, Esq. It is a valuable addition to the list of British 
tertiary Fossils, which resemble those of France. It is ac- 
companied by Cerithium Cornu-copia, C. giganteum, 
Ovula tuberculosa, Desk., and many undescribed shells.
