DescriptionThe shell is bright white and glossy with irregular bands of brown. There are three strong varices bearing an irregular fluted or wavy edge, and a sharply incurved spine on the varix of later whorls. The early whorls can appear translucent and show a brownish blue color beneath. The varix on the outer lip ends well above the siphonal canal, which is curved, and ends in a wavy flattened edge similar to the varices in shape. The aperture is subovate and the operculum is dark brown. Length 50 mm, width 25 mm.[2] DistributionThis species is found subtidally along the coast of Central America from San Marcos Island and Guaymas to Ecuador in water as deep as 82 m.[3] References1. ^1 {{WRMS species|406257|Purpurellus pinniger (Broderip, 1833)||24 April 2010}} 2. ^Sea Shells of Tropical West America, Second Edition, by A.
