They are ornamented with transverse black lines, dividing them into unequal spaces, the coloring of which is less deep than that of the interstices of the ribs.

The ribs are of a grayish or brown tint, of little variety, with wide spots, which sometimes form bands of a bloody purple.

The outer lip is marked by brown spots internally, and bordered externally by the last rib which is denticulated in a portion of its length.

The columella is slightly arched at the base, almost covered in its length by three very distant violet or brown spots.
