OCCURRENCE. — Recent: Eastern Atlantic ( 50-60 m in the North Sea, much deeper in Norway , the Bay of Biscay and Morocco : 135- 1000 m ) and Mediterranean ( 115-480 m ). DESCRIPTION Cellariiform colony. Internodes short (8-12 zooids). The first ramification arises from the third zooid. Pseudopores elongate and relatively rare. Gonozooid pyriform with a discrete ooeciostome situated near the base of the following zooid. REMARKS This species is poorly known and has rarely been illustrated. It has often been considered as a variety of C. eburnea (Linnaeus) to which it resembles. Harmelin (1990) distinguished a northern (Atlantic) and a southern form (Atlantic coast of Morocco , Mediterranean). The main differences are a higher number of zooids (9-12) per internode and a mitre-shaped gonozooid in the southern form.
