By Linnæus this genus was classed with the Voluta, though they are more
closely allied to the Murex; differing, however, from them by having no
varices.
Shell generally turbinated, but sometimes turreted, rugged, and thick;
spire variable in form; aperture elongated, terminated by a straight
canal, often rather short; the left edge almost straight, and formed by
a callosity which hides the columella; the right edge entire and sharp;
the columella with two or three unequal, almost transverse plaits.
