Whorls slightly to moderately convex. Protoconch with a very fine (hardly visible at 40 times magnification), densely placed, continuous, shallow, vaguely outlined spiral striation, and sometimes with fine, moderately spaced, shallow radial grooves towards the teleoconch only. Teleoconch with very fine (just visible at 40 times magnification) only slightly spaced, continuous, shallow, rather vaguely outlined spiral grooves on the upper surface; similar, but more densely placed grooves on the lower surface. This spiral sculpture is inconspicuous and patchy in some shells. Radial sculpture teleoconch: inconspicuous growth lines mainly, sometimes a few scattered, slight grooves. Umbilicus open, narrow, inner wall with an obtuse periomphalic edge; umbilical region distinctly concave. Dimensions: Height up to 1.1 mm; width up to 1.9 mm; diameters of the first three whorls 0.4-0.5 mm, 0.8-0.9 mm, 1.4-1.5 mm respectively; number of whorls up to 3 3/4; height aperture up to 0.8 mm; width aperture up to 1.0 mm.</paragraph>
