They are marked with numerous fine, slightly retractive, incremental lines, and exceedingly fine, spiral striatums. The periphery of the body whorl is well rounded. The base of the shell is slightly produced, well rounded, and marked like the spire. The aperture is subquadrate. The posterior angle is obtuse. The outer lip is thin.
