V. testa ovato-oblongd, costatd, postice levi, antice coarctatd, transversim sulcatd, late 
emarginatd ; spird brevi, sub-muricatd, apice sub-papillari : anfractibus conveais, ventricosis ; 
costis distantibus, postice bispinosis: labro tenui, levi; labio antice expanso ; columella 
quinguies plicata. 
Var. ANGULATA (fig. 6 4) testd breviori, latiort, costis numerosioribus ; anfractibus 
angulatis, unica serie spinarum coronatis. 
Shell ovate-oblong ventricose, contracted in front, ribbed, smooth except towards 
the base, where it is transversely furrowed ; spire short, armed with short spines ; apex 
conical, sub-papillary: whorls convex, rounded at the shoulder; ribs distant, extending 
to the middle of the whorls, crowned with two or three rather blunt, nodiform spines, 
which are lost on the last whorl of the fully formed shell. The aperture is effuse, and 
widely notched in front; the right lip is thin, sharp-edged, smooth within; the 
columellar lip thin, widely spread over the front part of the body whorl; columella 
furnished with one prominent very oblique fold in front, and three or four smaller ones 
behind. 
The English specimens agree perfectly with the French shells, and the examination 
of a longer series of specimens than that to which Mr. Sowerby had access, shows that 
individuals occur here, as well as in France, having the spire considerably produced 
(fig. 6 a).
