Protoconch of about 1.3­1.5 almost smooth whorls, with exceedingly fine spiral wrinkles or granules, last quarter whorl with a few axial threads. Teleoconch sculptured with fine collabral growth lines and, in some specimens, some are thickened into weak, irregular riblets; base evenly convex; umbilicus narrowly­open to partially closed in some adults. Aperture broadly ovate; peristome slightly thickened in mature specimens, inner lip forms narrow reflexion partially covering umbilicus; outer lip prosocline. Colour: shell semitranslucent to opaque; periostracum pale yellowish­brown to brown.

The whorls are very strongly convex and the shell outline is similar to that of the broadly­ovate forms of
