13 (/2) Calices in process of intratentacular division rare (most calices, even 

 terminal ones, appear discrete); septa not hexamerally arranged; 

 calices up to 15 mm in calicular diameter; coenosteal costae rarely 

 extend more than 5 mm from calicular edge (Fig. 16) Lophelia prolifera

 from part of a larger colony. Scale: 5 cm.
