Description – SL: 17.4–60. Spire of low to moderate height, outline convex. Spiral whorls smooth. Shoulder subrounded. Body whorl ventricosely conical, outline convex, smooth with fine ridges at the base. Subsutural flexure asymmetrically curved, of moderate depth. Colour pattern: spiral rows of dashes.
