(Original description) The fusiform shell is white, with an olive-gray more or less dehiscent dull periostracum.

In front of it and forming the shoulder of the whorl is a series of about twelve round-topped, slightly protractive, wavelike axial ribs, which only reach the suture in front of them in the earlier whorls, falling short of it in the later ones.

On the basal side of the whorl are numerous rather distant, distinct spiral striae, subequal and nearly equidistant, the interspaces a little elevated and, on the canal, becoming threads.

The outer lip is thin, sharp, with a shallow anal sulcus adjacent to the suture.

[2] This marine species occurs in the Gulf of Panama and off Point Arena, California, United States.
