The Warped Shells

Genus DISTORSIO, Bolt.

This genus differs from Triton in its distorted spire, and its irregular, contracted, thin, flaring aperture. It has three species distributed widely in warm seas. D. cancellinus, Roissy, is the type.

D. anus, Linn., has a very small aperture, from which the enameled lips flare into a white ruffled border, almost as wide as the body of the shell. There is scarcely any canal. The surface is cancellated, with brown bands on a white ground. Length, 2 to 3 inches.

Habitat.--Red Sea Indian Ocean, Philippines.
