(Original description) The shell is sharply conical, composed of six rounded, non-margined whorls with a well-defined suture. The aperture is ovate, with a thin outer lip. The columella features a white, lamellar, twisted tooth.
The shell is predominantly white, roseate, or salmon in color, often retaining traces of a dark brown epidermis. The body whorl is noticeably lighter in color compared to the upper ones.[3]
