Description
The shell size varies between 18 mm and 35 mm
The ovate, conical shell is smooth, polished, and whitish. A decurrent band of a rose color is seen beneath the suture, and three others surround the middle of the lowest whorl. That of the middle is broader and more apparent. The spire is composed of seven slightly convex whorls, ornamented with longitudinal ribs formed like folds, numerous and slightly elevated. The upper edge of the whorls is a little flattened. The base of the lowest is accompanied with two distinct ridges. The suture is edged with rounded tubercles situated between each fold, where they form a sort of necklace. The white aperture is ovate, contracted above by a transverse fold of the callosity. The outer lip is subtruncated, somewhat denticulated upon the lower edge, and marked with transverse striae internally. The columella edge is covered by a pretty thick callosity, spreading a little upon the belly of the shell.
