Purpurellus pinniger

The 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.

[2] This 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]
