316 PROFESSOR P. M. DUNCAN ON THE 



y Cakyophtllia inskipi, Duncan. 



The corallum is short and curved. It has a small base, which is marked by a fracture 

 of its attachment. 



The epitheca is dense, and covers the whole external surface ; it is granular, and con- 

 forms to the subequal costse, which extend downwards to the base without any marked 

 diminution in their size. Superiorly the costae join the stout and barely exsert septa. 



The calice is subcircular, shallow externally, and deep over the columella. 



The septa are alternately large and small, are largest at the margin, and are granular. 

 There are four cycles in most of the systems, and the higher orders are missing in the 

 half of two systems. 



The columella is very small, and situated deeply. 



The pali are very tall, and rather thick, but small. 



Height of corallum ^ inch ; breadth of calice -^ inch. 



The specimen from which this description is taken was dead, and came up in di^edging 

 No. 9, 539 fathoms, 2nd expedition. I have named it after Commander Inskip, one of 

 the naval officers who contributed so much to the success of the deep-sea di-edgings. 



y Caeyophtllia calveei, Duncan. 



The corallum is short, subturbinate and cylindrical. 



The costse are subequal, flat and granular from their epithecal coveiing. The primary 

 and secondary costee reach highest. 



The calice is circular in outline, is shallow ; and the primary and secondary septa are 

 very exsert and arched. 



The columella is small, and is composed of two or three processes. 



The pali are curved, projecting and twisted ; they are larger than the tertiary septa, 

 before which they are placed. 



The septa are unequal, and are marked by radiating eminences, which depend upon 

 curving of the laminae. 



There are six systems of septa ; and there are four cycles in five, and three in the 

 remaining cycle. 



Height of corallum -^^ inch ; breadth of calice -^ inch. 



I have named this beautiful coral after Captain Calver, to whom the dredging- 

 expeditions owe so much of their success. Dredged up from 292 fathoms (No. 24).

Cartophyllia VEKMipoRMis, Duncau. (Plate XL. figs. 13-16.) 



The corallum has a broad expanded base, a cylindrical and curved stem, and a slightly 

 elliptical shallow calice. 



The costse are distinct near the calice, where they are alternately large and small, flat 

 and granular ; and they are less distinct towards the base, where the granules are still 

 apparent.
