Nassarius stolatus is a species of sea snail, a marine gastropod mollusc in the family Nassariidae, the Nassa mud snails or dog whelks.

The pyramidal spire is formed of six or seven distinct, smooth, convex whorls.

These are covered with very prominent, convex, longitudinal folds, intersected only at the base, and upon the two or three upper whorls, by a few pretty deep transverse striae.

A dark red zone borders the suture, and a broader and browner band surrounds also the middle of the body whorl.

[2] This marine species occurs off India (Ratnagiri district, Maharashtra),[3] Sri Lanka, Indonesia and Thailand; in the Mediterranean Sea as an introduced species.
