Description
editThe shell has an elongate-conic shape. Its length measures .39 inch. The teleoconch contains 15 whorls that are moderately convex and are marked by a well impressed suture. On each whorl there are about 24 stout, obtuse approximate ribs which are obsolete anteriorly. The shell shows finely impressed spiral striae over all the surface except the summit of the ribs. The outlines of the spire are rectilinear. The aperture is subovate. The outer lip is thin. The columella is straight.[1]
Distribution
editThis species occurs in the Pacific Ocean off Panama.
