CCELOSMILIA. 21 



Parasmilia variegata Pourt. 

 Plate 1., fig. 13. 



Corallum simjjle, free, conical, often tlefonned ; the irregular shape 

 resulting from the young being originally attached to fragments 

 of the parent, which become gradually covei-ed over and incorpo- 

 rated into the base. No epitheca, co.stge distinct to the base, flat, 

 finely granulated, those of the third order somewhat broader and 

 more prominent than the others. Calicle oval, with moderately 

 deep fossa. Septa in six complete systems of four cycles, consider- 

 ably exsert and very unequal ; those of the first and second order 

 being closely connected at the wall with those of the fourth and 

 fifth respectively, and rising high al)0ve those of the third order, 

 which are the lowest of all. Septa entire on their upper edge, 

 l)ut deeply laciniated in the interior of the calicle, which thus 

 becomes filled with a false columella of curled and twisted septal 

 processes. The primary and secondary septa are colored of a dark 

 purple, which color continues some distance down the corresponding 

 costte. Those of the fourth cycle are lighter colored, with a dark 

 spot on the corresponding costte, a short distance below the border. 

 Those of the third order are white, with the same dark spot on the 

 costa. Dissepiments not observed, none in the upper three fourths 

 of the corallum. 



The young Inul out of the calicle of the parent, which is split 

 in consequence. 



Height 15 to 16 mm. ; diameters of calicle 10 and 13 mm. 



Off Conch Rettf, in 60 fathoms. 

 Off Carysfort Reef, in 63 fathoms. 

 Off Conch Reef, in 77 fathoms. 



CCELOSMILTA M.-Edw. & H. 



Coelosmilia fecunda Pourt. 



Plate I., fig. 12 ; Plate 111., figs. 4 and 5 ; Plate VL, figs. 14 aud 15. 



Corallum elongated, conical, irregularly bent, showing sometimes 

 a succession of slight swellings and contractions, attached by a 

 slightly thickened base. Costte finely granulated, rather obsolete 

 near the base. Calicle circular ^ or subelliptical, with deep fossa. 

 Septa entire, granulated finely, not exsert, in six systems and four
