The dark chestnut shell is variegated with white, especially upon the periphery and inferior portion of the body.

The outer lip is frequently black-bordered.

The want of nodules or spines disagrees with the character of the group; yet the relationship of this species with Vasula deltoidea is tolerably close.

Sometimes the body whorl[2] is, in adults, constricted around the middle.

This marine species occurs off Costa Rica, Panama, Ecuador and the Galapagos Islands.
