Clionella striolata is a species of sea snail, a marine gastropod mollusk in the family Clavatulidae.
The size of an adult shell varies between 14 mm and 22 mm.
The squat, bucciniform shell has convex whorls and a rather large aperture. The siphonal canal is barely notched. The anal sinus is very shallow. The arcuate ribs number 14-19 per whorl, but becoming sometimes obsolete on later whorls. The color of the shell consists of patches of yellowish-brown.
Characteristic for this species is that the spiral sculpture shows 4âÂÂ5 well-spaced grooves per whorl. Furthermore, the subsutural cord is feeble.
This marine species occurs in lower mid-tidal rock pools off Namaqualand to Cape Hangklip, South Africa.
