Shell: The shell is sinistral and show a wide umbilical slit. It is spindle-shaped and slightly swollen, featuring raised, irregular ribs that evolve into densely spaced, regular longitudinal striae. The surface is matte-glossy, violet in color, with a reddish apex, and when fresh, covered with a bluish bloom. The shell has 10 to 10.5 convex whorls, marked by a deep suture. The suture line and the densely wrinkled, prominently swollen neck are white. The aperture is pear-shaped. The lip is continuous, slightly detached, strongly reflexed, and lipped, with the lip being brownish-white and the palate yellow-brown. The lamellae are short and receding. [2]
