Its colour is crystalline white, with or without a dorsal blot and zone of ochraceous-orange only on the body whorl.

The radials are wide spaced, prominent, flexuous, perpendicular, and continuous ribs, which diminish at the shoulder and gradually vanish on the base.

The spirals are extremely fine and close threads, evenly distributed over the whole surface, and microscopically beaded.

From the varix a thin lip projects, curving forwards at the periphery, and followed beneath by an insinuation.

On the inner lip a small tubercle rises opposite the sinus, and the columella is smooth.
