“ Shell smooth, thick in the middle, brown, with a narrow whitish band; spire striated, the striæ with internal punctures: outer lip crenated; pillar 5 plaited. A species evidently unknown to Lamarck; the upper margin of each whorl is thick and projecting; the striæ on the body whorl are nearly obsolete, but on the spire become deep, remote, and having internally minute hollow dots; the inner margin of the exterior lip is strongly crenated, the aperture smooth, and the pillar with five strong teeth. ”
