CCELOSMILIA. 21 



Farasmilia variegata Pourt. 



Plate I., fig. 13. 



Corallum simple, free, conical, often deformed ; the irregnlar shape 

 resulting from the young being originally attached to fragments 

 of the parent, which become gradually covered over and incorpo- 

 rated into the base. No epitheca, costge 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; closelv connected at the wall with those of the fourth and 

 fifth respectively, and rising high above those of the third order, 

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

 but 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 

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

 spot on the corresponding costae, 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 bud out of the calicle of the parent, which is split 

 in consequence. 



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

CCELOSMILIA M.-Edw. & H. 



Coelosmilia fecunda PorRT. 



Plate L, fig. 12 ; Plate IIL, figs. 4 and 5 ; Plate VI., figs. 14 and 15. 



Corallum elongated, conical, irregularly bent, showing sometimes 

 a succession of slight swellings and contractions, attached by a 

 slightly thickened base. Costae 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
