It is of a diaphanous white. The sutures are indistinctly apparent. The spire is composed of six convex whorls, ornamented at their base with spots of a duller white. The body whorl is as large as all the others, striated at base, and surrounded, towards the middle, with small, distant spots, articulated by a reddish line. The aperture is ovate.
