Shell description
The shell of this species is orbiculate-globose, lightly striate, hardly shining, covered with a corneous epidermis. The shell is composed of 5 convex whorls. The spire is obtuse. The suture is hardly impressed, not marginate, bordered below by a blackish band. The last whorl is globose, not carinated, divided by a submedian blackish band above, the upper part having only a few spots near the periphery, the base with numerous brown spots arranged concentrically.[2]
The shell aperture is semilunar and a little oblique. The columellar (parietal) margin is arcuate, convex, and three-toothed. The median tooth is the most strongly developed. The peristome is white, reflexed, and has six equidistant and equal white teeth, which are violet-tinted at their bases.[2]
The width of adult shells is 33 mm, the height is 18 mm.[2]
