Whorls 11¼ to 11¾, first 2½ subtranslucent, the remaining whorls porcelaneous. Second to fourth whorls rarely and but faintly mottled. The mid whorls possess nearly parallel sides, first to seventh whorls smoothly and convexly conic. Body whorl sharply rounded below the periphery. Spire pointed and produced at an angle of 56°. Aperture subovate. Mid-parietal wall supporting a well developed tooth, its long axis set at right angles with the face or the aperture.
