The diameter of the shell attains 25 mm.

The shell presents a notable wide umbilicus and possesses a relatively thin texture. The shell is closely rugosely plicate above. It exhibits a brownish hue. The suture is impressed. The shell comprisis 8 whorls, each slightly convex. The body whorl descends shortly towards the front with a subtly angular periphery accented by white banding. The base of the shell maintains a convex shape with visible striae. Its outer lip is thin featuring a slight angular reflection.[2]

Distribution
