Teleoconch of about 2.0–2.2 whorls, rounded except for angulations from two prominent carinae, one mid-dorsal, one mid-basal; whole surface with distinct spiral sculpture: on inner dorsal part of shell spirals weak to subobsolete, with linear interspaces; on outer side of dorsal carina spiral lirae have interspaces 2–3 times their width while on periphery lirae slightly weaker, with narrow interspaces; about 4–8 lirae on outer side of dorsal carina and about 9–11 spiral threads on inner side at end of penultimate whorl; irregularly spaced commarginal growth lines cross spirals. Periphery evenly convex, spiral lirae weaker and closer together in middle part of peripheral area, similar in strength and spacing on lower peripheral area and base as on outer dorsal surface. Base evenly convex except for mid-basal carina, umbilicus wide (more than half width of base), basal spiral sculpture continuous within. Sutures moderately impressed. Aperture near circular, with simple, slightly thickened peristome, external varix well developed, narrow, slightly behind edge of aperture. Periostracum light reddish brown, shell white.
