Shell small, yellowish white, with a zone of wax yellow, which extends over the central half of each whorl, leaving the posterior half between the sutures and the basal tip white. (Nuclear whorls decollated); postnuclear whorls well rounded, ornamented with strong lamellar ribs of which ten occur upon all the whorls. These lamellae are slender, recurved, and project at their tips considerably above the. strong shoulder of the whorls. The intercostal spaces are scarcely at all depressed, they are about three times as wide as the ribs and are marked by slender and equally spaced spiral threads, of which seven occur upon the first, eight upon the second, and ten upon the penultimate whorl between the sutures. In addition to the above-mentioned sculpture, the spire is marked by numerous, very fine axial lines of growth; summits tabulatedly shouldered; the shoulder crossed by the ribs. Periphery of the last whorl gently rounded. Base quite prolonged, marked by the continuations of the axial ribs which extend quite prominently to the extreme anterior portion of the base, and about fifteen equal and equally spaced, spiral threads, which are equal to those of the spire in strength and spacing. Aperture strongly channeled anteriorly; outer lip reenforced by a very thick varix which is expanded and flattened and is marked by the spiral sculpture; inner lip strongly curved, reflected over and appressed to the base, parietal wall covered by a thick callus.
The type, Cat. No. 227763, comes from Port Alfred. It has four postnuclear whorls, and measures: Length, 0 mm.; diameter, 3 mm. (Coll. No. 858).
