The size of the shell varies between 10 mm and 14 mm. The narrowly umbilicated shell has a conoid-depressed shape with 5 whorls. The first whorl is roseate, eroded, the following convex above, depressed beneath, whitish or rosy, flammulated with brownish-violet radiating maculations, obliquely striate and spirally lirate. The lirae are flat, narrow and not granose. The body whorl is dilated, subangulate above, depresso-carinated at the periphery, convex beneath and ornamented with 9 concentric reddish lirae. The aperture is oblique and subquadrate. The lip is simple. The columella is arcuate, denticulate at base, slightly calloused above, almost covering the umbilicus.[2]
