Shell short, broadly conical with the height corresponding to two times the width. Shell wall thick. Protoconch homeostrophic, consisting of around two convex whorls. Teleoconch whorls flat, smooth, separated by shallow sutures. Incremental scars not strongly developed. Aperture small and low, the height corresponding to 38 % of shell height on measured specimen and 1.7 times the aperture width. Outer lip slightly curved in frontal view, in lateral view strongly prosocline, describing a gently convex curve with no central projection. Inner lip curved with no parietal callus.
