(Original description by
Paul Bartsch) The height of the shell attains 0.8 mm, its diameter 2.3 mm. The small, semitransparent shell has a planorboid shape. It is closely, spirally striated. The 3½ smooth, shining
whorls are moderately rounded. The succeeding turns increase regularly in size, rendering the
apex considerably lower than any of the succeeding turns. The last is the most elevated. The whorls are well rounded and separated by strongly impressed
sutures and marked by many equally strong and equally spaced, somewhat wavy, incised spiral lines and fine incremental lines. At more or less regular intervals there appear slight constrictions which coincide with the lines of growth. The periphery of the
body whorl is well rounded. The base of the shell is well rounded, very broadly and openly umbilicate to the very
apex, marked like the upper surface. The suboval
aperture is oblique. The outer
lip is thin. The short
columella forms an almost straight line with the faint callus of the parietal wall. ==Distribution==
