Shell subglobose, very dark brown, mottled and streaked with yellow horn color. Nuclear whorls two and one-half, well rounded, smooth. Postnuclear whorls well rounded, decidedly shouldered at the summit, marked between this and the suture by broad, depressed, spiral cords, of which live occur upon the first, six upon the second, while, the last whorl has eight, owing to splitting of the primary cords. The spaces that separate the cords are. less than one-half the width of the cords and are very feebly impressed. In addition to the above sculpture the spire is marked with feeble, decidedly retractive lines of growth which pass over the cords and grooves. Periphery of the last whorl subangulated, marked by a slender spiral cord. Base moderately long, well rounded, and openly, broadly umbilicated, marked by 13 subequal and subequally spaced spiral threads which are wider than the spaces that separate them. In addition to the spiral cords, the. base is marked by the continuation of the lines of growth. Inside of umbilicus smooth. Aperture large, subquadrate; outer and basal lips thin, forming a decided angle at their junction; inner lips oblique, smooth, sinuous; parietal wall glazed with a thin callus.
The type and two specimens of the species, Cat. No. 90108a, U.S.N.M., come from the Cape of Good Hope. The typo has three and one-fourth postnuclear whorls, and measures: Altitude, 7 mm.; greater diameter, 8 mm.
