This is a small thin globose shell with no flare to a thin lip. It has a smooth surface with a low spire that is occasionally eroded. The suture is impressed with a slight overgrowth by successive whorls. There is no spiral structure of cords or ridges and only very faint axial growth striae. The aperture is bluish gray with lighter gray on the parietal shelf. There are no teeth on the straight columella or the outer lip. The parietal shelf is smooth, flat, and occasionally slightly swollen. The bluish gray coloring of the aperture carries over onto the apical (upper) portion of the parietal shelf. The operculum exterior surface is brown with gray staining, especially around the nucleus and along some of the numerous axial growth striae. These striae form small ridges along the columellar (lower) margin or the growth portion of the operculum. The interior of the operculum is gray. There was no evidence of a corneous lamella along the labral margin of the operculum. The apophysis is thin, very slightly flared, longitudinally corded, and swept back at 45°. There is no nuclear tooth, peg, medial tooth, or lateral tooth. The periostracum is very thin, transparent, and easily worn through. The pattern of dark brown zigzag lines crossing lighter brown or yellowish areas is often completely hidden with a shell that looks almost solid brown or black. This pigment layer is thin and rather easily worn away revealing a white shell layer underneath.
