(Original description by E.A. Smith) "The depressed shell has an ovate shape with the raised ridge parallel to the row of holes only slightly raised. The upper surface exhibits numerous spiral lirae, minutely squamose through the close elevated lines of growth. The four open holes are rather prominent. The space between the holes and the outer margin is concave or channeled. The color of the shell is brownish-white with radiating blood-red streaks, narrow at the suture and gradually widening outwards. The left outer ledge is crossed by oblique, alternating, dark olive and pale stripes. The interior surface is beautifully iridescent, ridged and grooved. The columellar plate is whitish pearly, flattened, edged externally with a thin red line."
