The outer lip is dilated, particularly towards the base, and forms externally a very thick convex margin, the external part of which is sharp, undulated, and its internal surface furnished with ten or twelve transverse, distant teeth, resembling folds.

The inner lip consists of a smooth plate, convex and white, which partially covers the body of the shell.

The columella presents a pretty deep emargination, above which are observed several transverse thick folds, and some others, less numerous, more oblique, and less distinctly marked.

The color of the animal is of a beautiful white, marked upon its circumference with triangular flames of a violet brown.

The tentacles are long, slender and pointed, spotted with brown, in the form of triple rings.
