Redescrição:

(Breure, 1978): “Shell narrowly perforate, with straight to slightly convex sides, rather solid. The following colour patterns occur (roughly classified): (a) entirely white; (b) white with 3-6 narrow, interrupted, brown spiral bands; (c) do., but with alternating narrow and broad bands; (d) do., with two broad bands. In all patterns the umbilicus is encircled by a broad brown band. Surface hardly shining, smooth. Protoconch with interrupted low axial wrinkles and numerous fine spiral lines. Whorls moderately convex, especially in the more globose forms; suture well impressed. Aperture (broadly) ovate, the margins more or less converging. Peristome thin and simple. Columellar margin slightly dilated above.”
