Shell small, yellowish white. Nuclear whorls small, one and a half, smooth, forming a very small, well-rounded, white apex. Postnuclear whorls with a very strong sloping shoulder, which is bounded anteriorly by a strong tuberculated spiral cord. In addition to this cord, the whorls arc marked by three additional cords, which decrease in strength successively from the strong cord at the shoulder, to the suture. The space between the strong shoulder and the summit of the shell is marked by a strong spiral thread. Base of the last whorl marked by a peripheral cord, about as strong as the one adjacent to it posteriorly and two others as strong as this, having the same spacing as those on the spire. The columella is provided with four cords, of which the fourth, which marks the anterior limit of the columella, is as strong as the first, while the two intermediate ones are less strongly developed. In addition to the spiral sculpture, the whorls are marked with rounded, low, quite regularly spaced, axial ribs, of which 10 occur upon the first and second, and 14 upon the last turn. These ribs render the spiral cords tuberculated at their junction with them. In addition to these strong axial ribs, the entire surface of the shell, between the sutures and the anterior half of the base, is marked by numerous, quite regular, closely spaced, axial threads, which are best shown in the spaces between the spiral cords and on the tabulated summit of the whorls. Aperture rather large, scarcely channeled posteriorly; outer lip very thick, rendered denticulate on the outside by the spiral cords; inner lip and parietal wall glazed with a thin callus.
The type, Cat. No. 250463, U.S.N.M., comes from Port Alfred (Coll. No. 1336). It has four post-nuclear whorls and measures: Length, 3.1 mm.; diameter, 1.5 mm.
