External colors are white with occasional brownish spiral stripes, which on some specimens may be absent.

The colors of the aperture, or opening of the shell is pink at the edges and the glossy shield over the columella.

At the top and some of the left side of the shield, the pink merges into a dark chocolate-brown staining, ending at the posterior canal.

Further inside, the shell fades into a porcelain-white with faint, pink tinting.

This species occurs in the Pacific Ocean between Baja California and Peru (but not along the Galapagos Islands).
