Profile of whorls slightly convex. Spire longer than aperture. Surface smooth, without any sculpture, the growth-lines for the most part very indistinct; but a few spiral lirae on rostrum. Outer lip sometimes with feeble varicoid thickening; no plicae on inner surface. No periostracum. 11X5 mm. Operculum subtriangu- larly ovoid, thickened on inner surface in basal half ( from nucleus onwards), the thickening extending along both lateral margins and also forming a midrib, leaving a semi-oval thinner area between the latter and the margins; midrib not (or scarcely) visible on external surface. White, operculum amber. Radula normal, proximal cusp on lateral plate well separated from the bifalcate Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
