Thus far, endemic to the strait of Gibraltar, but its presence in the sea of Alborán and along the shores of the western Cádiz province remains possible; also, little is known about the micro-molluscs of northwestern Africa. Grazer and deposit feeder in the infralittoral, it is found on stones and on sandy bottoms, among photophile algae.

« Shell sub-globose, whitish in colour, dull and frosted in appearance, owing to the entire surface being covered with very numerous, fine, close-set, flexuous striae following the direction of the lines of growth ; on the umbilical area and adjoining part of the base there are also numerous, much stronger spiral lines, finely granulated by the striae just described ; whorls two-and-a-half, convex ; suture very distinct though not deep ; spire but little raised ; mouth nearly circular ; outer lip thin, presenting two shallow sinuations, one at the periphery and one below ; umbilicus rather large ; operculum like that of C. nitens. […] This species was very abundant in the dredgings, many of the specimens still containing the animal. The only species for which it could be well mistaken is C. nitens Philippi, from which it differs in its smaller size, lustre-less and striated surface, basal as well as umbilical striae, and much larger umbilicus. » – op. cit. p.3-4.
