Description

The depressed-conical shell is profoundly umbilicated. The 5½ whorls are slightly convex and ornamented with transverse granulose lirae. The interstices are obliquely longitudinally striated. The body whorl is encircled by a prominent crenulated carina at the periphery. The aperture is subquadrate. The inner lip is reflexed in the middle. The outer lip smooth within. The base of the shell shows a close grnuulose line. The umbilicus is moderate. The color of the shell is pale brown, ornamented with radiating brown patches.[4]
