Description
The size of the shell varies between 9 mm and 15 mm. The thick, narrowly perforate shell has a conoid shape with an acute apex and 7½ whorls. The first one is rosy, smooth, the rest convex. They are separated by linear sutures. They are spirally lirate with granose lirae;, 6 on the penultimate whorl, of which the 1st, 3d, 5th are entirely reddish, the 2d, 4th, 6th composed of alternating white and black granules. The body whorl is globose, bearing 15 or 16 lirae, somewhat convex beneath. The concentric lirae are uniform yellowish-brown, often in pairs, separated by single alternately white and black articulated lirae. The oblique aperture is rhomboid. The lip is thickened, plicate and dentate above. The columella is oblique, terminating in a large, plicate, contorted, truncate tooth. The narrow umbilicus is profound with a crenulated border. The parietal callus is wrinkled.[3]
