aperture are very large. Its color is reddish-brown, marked with white on the spiral ribs. The small
spire is very short. The four whorls are convex, the inner 1½ are smooth, the rest have strong, separated spiral lirae, the interstices wider than the lirae, rendered pitted by raised, regular rib-striae each interliral interval with a central spiral thread. There are 3 principal lirae on the penultimate whorl. The outer
lip is inserted on the fourth. On the base of the shell there are 8 concentric lirae, alternately larger and smaller, the inner one bounding the
umbilicus and spirally entering it. The large
aperture is oblique, finely sulcate, pearly and iridescent inside. The outer lip is thin. The
columella is arcuate, not toothed, a trifle reflexed above, connected with the upper lip by a short, shining, white callus. The narrow
umbilicus is funnel-shaped.
