Nucella, common name dog whelks or dog winkles, is a genus of small to medium-sized predatory sea snails, marine gastropod mollusks in the subfamily Ocenebrinae which is part of the large family Muricidae, the murex snails or rock snails.

(Described as Polytropa) The spire is acuminate. The whorls are foliated or tuberculose. The inner lip is flattened. The siphonal canal is small and oblique. The aperture is narrowed at the forepart. ^[2]
