Adult shell large tor the genus, maximum diameter 12 mm., planorboid, widely and deeply umbilicate. Axial sculpture consists of 15 to 17 strong, rounded cords which encircle the entire whorl. Each cord becomes swollen or nodulose at the point of intersection with each of the 12 spiral, much smaller, rounded cords. The fourth, fifth and sixth spiral cords are almost as large as the axial cords and are situated respectively at the top, middle and bottom of the periphery of the whorl. Within the umbilicus, the* axial cords narrow down and line up into a strongly serrated, rather prominent umbilical, spiral cord. Peristome circular, moderately thickened and bearing the slightly nodulate ends of the axial cords. In fresh material, the entire outer surface of the shell is covered with fine, axial striae or "frosting." Operculum circular, concave from the outside, with a chitinous base on the inner surface and on the outer surface with about 20 multispiral rows of rat her widely-spaced calcareous, round beads.
Height 2.1 mm ; max. diam. 4.2 mm ; min. diam. 3.5 mm

As lippistes acrilla:
Shell thin, white, pianorboid, of three and a half whorls; radiating sculpture of about fifteen ridges, faint on the base and summit, making small nodules where they cross the fine spirals, and prominent and strong on the periphery between the three peripheral carinae. Other radiations are only due to lines of growth which are sometimes slightly elevated. Spiral sculpture of three prominent and strong peripheral ridges, of which the uppermost forms the chief periphery, the others being slightly nearer the axis; between these, nearly square deep reticulations are formed by the radiating ridges before described. Beside these there are three faint spirals on the upper and three on the basal surface, nodulated at their intersections with the radii. Umbilicus ample; inner margin of the aperture nearly circular, the outer part modified by the sculpture. Max. diam., 4.3; min. diam., 3.0; alt., 2.0 mm.
