Original Description

"Shell cylindrical, obese, strong, rimate and perforate, the lower two or three whorls of approximately equal diameter, those above forming a rather short cone with sides diverging at an angle of 85° to 90°.  Whorls 10-11, the earliest 1-2½  white or corneous, several following finely and sharply striated, the remaining whorls nearly smooth; last whorl ascending in front, somewhat tapering below, and generally striated at the base. Brown, marbled with very irre­gular stripes and dots of white. Aperture short, showing a small short parietal tooth and a small columellar fold; peristome white, thickened and convex, reflexed and recurved, continuous, the parietal margin more or less calloused.

Alt. 23½, greatest diam. 13, length of aperture 11 mm.

Alt. 28, greatest diam. 12½, length of aperture 11 mm.

Alt. 24, greatest diam. 11½, length of aperture 10 mm.

Type locality: Port of Vita, Cuba (Francisco E. Blanes).

This species resembles C. dimidiatum, differing in being of less rude texture, less squarely obese form, higher terminal cone, no trace of a keel defining the base, etc.

It has the coloration of C.vulneratum." (Pilsbry & Vanatta, 1899:476)
