Cominella maculosa, common name the spotted whelk, is a species of predatory sea snail, a marine gastropod mollusc in the family Cominellidae, the true whelks.

The ovate, conical shell has a bluish ash color, traversed by distant lines, articulated and generally formed by oblong black points.

They are slightly convex, and united by a pretty fine and regular linear suture.

The aperture is oblong ovate, slightly longitudinal, smooth and of a chamois-yellow color.
