Description

(Original description) The shell is conically ovate, consisting of six well-rounded whorls. The suture is moderately defined, becoming deeper at the junction with the last whorl. The aperture is small and ovate, while the short columella features a nearly transverse plicate tooth. The shell's coloration ranges from brown to chestnut, adorned with intricate white transverse lines and markings. These patterns, resembling lacework or embroidery, are applied to the epidermis in various designs.
