Descrição:

(Pilsbry, 1896): “Shell obese-ovate, solid, white, with irregular indistinct fleshy or gray-blue streaks and small scattered dots, the latter translucent by transmitted light, these markings often inconspicuous; earliest whorls fleshy or corneous, smooth. Protoconch smooth, with very fine axial striae near the sutures visible only under magnification.

Surface slightly shining, with irregular wrinkles of growth, and seen under the lens to be cut by superficial incised spiral lines into series of long granules, often absent on middle and base of last whorl. Spire short, conic, composed of 5.5–5.75 very convex whorls, separated by deep sutures. Last whorl rotund. Aperture slightly oblique, round-ovate, over half the shell’s length, crimson, rose or red–brown within, becoming light brown in the throat; lip moderately thick but sharp, not expanded, the edge light in color. Columella broadly dilated, its inner edge straight or lightly concave; parietal callus thin, colored. Umbilicus large, colored inside.”
