Its color is cinereous, reddish, or purplish-brown, obscurely clouded, dotted or flamed with white The conical spire is acuminate. There are about seven whorls, slightly convex, spirally striate, microscopically obliquely striate. The lirae are generally subobsolete on the last whorl. The periphery is obtusely angulate. The aperture is rather small, oblique, rounded-quadrate, angled at the base and smooth within. The columella is arcuate above, straightened below.[2]
