Description

The height of the shell attains 24 mm. The acute shell contain six gently rounded whorls with fine, revolving, thread-like ribs. Four or five ribs near the suture are granulated. The body whorl is roundly carinated. The base of the shell is flattened, with about twenty-five revolving striae. The thick columella is not reflected, but its base is somewhat grooved or depressed behind it. The aperture is about one-third of the length of the whole shell. It is rhomboidal, pearly, and smooth. The shell has a beautiful light salmon color, ornamented near the suture and carina with alternate patches of light yellow and chestnut-brown.

Distribution

This species occurs in the Pacific Ocean off California.
