"Shell rather thin, cylindrical, the latter three whorls of about equal diameter, those above slowly tapering to form a rather long, convex cone. White, variegated with gray-white. Whorls 10½, slightly convex, two nepionic smooth, those of the cone very finely, sharply striate, the latter four with coarser riblets, much narrower than their intervals. Umbilicus a short, compressed rimation.
Aperture ovate, large and open, white, higher than wide. Peristome expanded and recurved, rather thick; axial fold basal; parietal fold narrow, nearly a half-whorl long; an acccessory fold ascends around the root of the columella, but at the apertural termination approaches close to the main parietal lamella.
Alt. 29, diam. 10½; alt. of aperture 11 mm.
This is an albino form of the Diacerion group, differing from C. rubicundum and its immediate allies in the greater distance between the two parietallamellre within." (Pilsbry & Vanatta, 1896:337)
