Pupa solidula, common name the solid pupa, is a species of small sea snail, a marine gastropod mollusc in the family Acteonidae.[1][2]
The size of the shell varies between 15 mm and 40 mm.
The thick shell is ovate, oblong and cylindrical. It shows slightly impressed, transverse striae, traversed by oblong, brown spots, and often intermixed with other reddish spots, especially upon the whorls. A narrow, white band, surrounds towards the middle, the lowest whorl. The conical spire is pointed. The oblong aperture is narrowed, a little compressed towards its upper third, and dilated at its lower part. Two folds upon the columella, are separated by quite a deep, semicircular groove, the larger, two-lobed.[3]
