Protoconch smooth, except for minute radial wrinkles, translucent, wide and flattened, of 2.5 successively larger whorls, ~ 0.4 mm; transition to teleoconch unclear, marked by gradual appearance of sculpture. Outer sculpture mostly small, rather prosocline axial cords, each one narrow, from suture to suture, separated from each other by distance 4 to 5 times wider than each cord. Aperture non-deflected, simple, even with last whorl. Umbilicus open, deep.
