The base of the shell is produced, much exceeding the spire, which is low and gradated.

The shell contains four whorls, the first minute, unsculptured, the others rapidly increasing in size, parted by channelled sutures.

Sculpture : the upper whorls carry three thick, elevated, spiral ribs, divided by broad, deep grooves.

These vanish on the body whorl, which is entirely covered by dense, microscopic spirals so crossed by radials as to give the effect of fine punctures over the whole surface.

The umbilicus has superiorly a narrow spiral perforation, inferiorly a trough hollowed between the columella and the funicle.
