Description

The length of the shell attains 47.8 mm, its diameter 26.3 mm.

(Original description in Latin) The shell is sinistral, imperforate, and ovate-oblong. It exhibits a solid and thick structure. Its surface appears irregularly finely striated and somewhat dull, displaying a pink or tawny base color. It is ornamented with close-set wavy broad chestnut streaks and four upwardly whitening lemon-yellow bands. The spire presents a convex-conical shape with a somewhat acute, black apex. It contains seven somewhat convex whorls. It shows a slight excavation below the suture. The body whorl is scarcely shorter than the spire and is rounded at the base. The columella is thick and white, scarcely twisted above. The aperture lies obliquely and has a semi-oval form, appearing white inside. The peristome is thick, white, and expanded-reflected, with its margins joined by a thick, long-extending callus.^[2]
