Description

The height of the shell attains 4⅓ mm, its diameter 2½ mm. The shell is limpet-like, but with a recurved beak projecting beyond the posterior outline of the aperture. The shell is very convex, sloping convexly toward the front margin. The surface of the shell is lusterless, showing under a lens rather rude concentric growth lines, and very numerous, close, fine striae, radiating from the apex to the margins. The coloration consists of narrow red stripes obliquely descending from the median line to the borders, forming a series of V-shaped markings. The beak is rolled forward and a trifle inclined laterally, but the (dextral) apical
