Description
Original description :The shell is deeply chinked, conoid-lenticular, and somewhat solid, with a sharp keel. It is pale, with a narrow chestnut band above the keel and at the suture. The spire is a short cone. There are 5 rather flat whorls, the upper ones slightly striated. The body whorl is irregularly and wavy-ribbed and striated, with a convex base marked with chestnut spots, and is pitted anteriorly. The aperture continues the periphery of the spire and is semicircular, constricted by 6 strong, wavy lamellae. The peristome is white, widely expanded, and reflected, with a large, oblong hole on the right margin at the insertion point.
The length of the shell attains 13 mm, its maximum diameter 24.5 mm.
