-- Shell ovate turreted, whitish-brown, with eleven or twelve longitudinal interrupted ribs forming long tubercles on the centre of the whorls; the whorls with distant impressed spiral lines near the suture, with a rather flattened slightly nodulose band; the mouth rather more than one-third the length of the shell; outer lip thin inside, grooved; tail short, with a linear depression on its columella side; axis ten-twelfths, diameter four-twelfths of an inch.

Cassis achatina, var.Lam.Hist.7 226.
A worn specimen, apparently a variety of this species.

It is entirely smooth, polished, and has the last whorl near the spire slightly concave, edged with a scarcely raised rather nodulous line, the outer lip is very thick, grooved on its inner edge, and the columella is distinctly plaited.
It may perhaps prove to be a new kind; but the species of this genus are so exceedingly apt to vary, that I do not wish to increase the number of the already too much extended lists of Lamarck and others.
