Description

The length of the shell varies between 13 mm and 17 mm.

This species is remarkable for its very slender form and the punctate striae between the ribs. The folds on the columella correspond to the oblique ridges between the sulci on the cauda of the body whorl. These ridges are spotted with pale brown.

Distribution

This marine species occurs in the Indo-Pacific; also off Australia (Northern Territory, Queensland, Western Australia)
