(Original description) The small shell is lanceolate and contracted at the sutures.

Sculpture : Fine spiral grooves, crossed by still finer radials, ornament the protoconch.

The third whorl has a prominent keel on the shoulder, beneath which is a fainter spiral.

On the fourth whorl the radials first appear as eight prominent round-backed ribs, crossed by two, afterwards three, spiral cords, forming deep meshes by their intersection.

The spirals multiply by intercalation till on the body whorl they amount to twenty-five, but there also they are insignificant compared to their initial stage.
