Protoconch of a little more than 1/2 whorl, smooth, with a diameter of about 220 mu. Columella very short and sloping, with a strong denticle on its upper part and a very strong tooth at its base. Inside the outer lip there are 6 strong spiral ridges and an anal tooth somewhat larger than the others. Umbilical border with 2-3 thin crenulations. In the spaces between cords, there are very fine spiral threads (between 2 and 5 on last whorl), crossed by fine oblique growth striae. Dimensions: The largest shell studied is the holotype of 8 mm.
Radula studied from specimens from Santa Maria, Angola. The rachidian tooth is trigonal with lateral margins more elevated and less rounded; cusp blunt and not very elon¬gate, with an evident M-shaped profile.

The studied specimens from the type locality have 5 1/2 whorls, the protoconch is pinkish, the first 2 1/2 whorls of the teleoconch are coral red, and the subsequent ones dark brown, with 5 subsutural white blotches on the last whorl (8 in the holotype). The number of nodulose spiral cords is lower in some specimens in our material (only 16 on the last whorl, 7-8 at the periphery, and 8 at the base) than in the holotype. C. pseudocorallinus differs from C, corallinus because the lower tooth of the columella is large but not bifid as in C, corallinus; also, because the basal cords are finer and more numerous (C. corallinus has only half the number, and they are more widely separated).

South of Angola, Benguela and Namibe provinces. Infralittoral species, living between 1 and 10 m, on rocky bottoms carpeted with encrusting calcareous algae.
