Description
edit(Original description) The shell is globose-conic and moderately thickened, with a brown coloration that shades off to a smoky white along the suture and the periphery of the body whorl. It features rather light growth striae, interspersed with a few spiral series of punctures. The apex is obtuse, and the spire's outlines are variably curvilinear. The shell has slightly fewer than five moderately convex whorls with a well-impressed suture. The body whorl is subplanulate beneath. The aperture is semi-elliptical, compressed above and below, and laterally dilated. The outer lip is sinuate, well-expanded, and reflected except at the extremities, with a slit that is rather wide but not very deep. [2]
