Shell elongate-conic, slender, white with narrow brown bands. Nuclear whorls 2,5, dextral, strongly rounded, smooth, forming an elevated spire. Post-nuclear whorls with a strong shoulder one-third of the distance between the sutures anterior to the summit, the rest well rounded, marked by strong, narrow, sinuous, slightly protractive, axial ribs, of which 10 occur upon the first, 12 upon the second and third, 14 upon the fourth and fifth, and 16 upon the penultimate turn. Intercostal spaces about three times as wide as the ribs. The spiral sculpture consists of moderately broad, low, flattened spiral lirations, separated.by channels a little less in width than the lirations. These lirations grow gradually wider from the summit to the periphery. There are 14 of them between the sutures on the penultimate turn. Base attenuated, marked by the continuations of the axial ribs and about 14 spiral lirations, those of the outer half where the ribs are absent being much stronger than the rest. Aperture almost oval, decidedly expanded at the posterior angle, where the outer lip is somewhat reflected by the shallow channel. Middle of the outer lip slightly inbent, thin; columella sinuous and somewhat twisted, covered by a thin callus which extends up on the parietal wall.
The type has nine whorls and measures: Length, 12.4 mm.; diameter, 4 mm. It and three other specimens, Cat. No. 187004, U.S.N.M., are from Port Alfred (Coll. No. 536). Cat. No. 187005, U.S.N.M., contains two specimens from the same locality (Coll. No. 537).
In some of the specimens, the spiral lirations show a tendency to split.
