[edit]The shell measures 1.6 to 2.0 mm (mean: 1.8 mm) in height and 0.9 1.05 mm (mean: 1 mm) in width. It is oblong ovoid with 4.5 to 5.35 whorls (mean 5). The aperture is sinistral and relatively small. The aperture edge is bent (indented) and slightly thickened and the aperture is slightly notched, the notch continuing outside as a spiral groove.
