The shell is rather solid, uniform pinkish buff, 1,5 smooth, moderately convex whorls of the nucleus remain (about one being lost). Seven later whorls are rather strongly convex, with a simple, weakly undulated and scarcely impressed suture. Sculpture of about eight rather sharp axial ribs with wide, concave intervals, the ribs continuous, bulging in the peripheral region but with the crests straight in profile, or on the last whorl a little concave, in the subsutural region, where the very fine lines of growth are arched moderately backward. Near the anterior end there are several weak spiral threads. The siphonal fasciole is convex, ill-defined. The aperture is short Shortly behind the outer lip there is a varix not much stronger than the other ribs. Outer lip broken, but there seems to have been no stromboid notch, and the anal sinus was moderately deep, rounded, the siphonal sinus rather shallow. Inner lip calloused throughout, its edge raised, with a rather thick pad at the posterior angle. Length 12 mm., diam. 5 mm.

The absence of spiral striation except at the anterior end, the strong ribs and lacking anal fasciole, are the chief features of this shell
