they are lamellar and well developed, often spiny, Eudotlieca 

 well developed. Exotheca between and usually beyond tbe 

 costse, well developed. Epitbeca may or may not exist. G-em-

(1850). 



This genus has but one species, wMch has all the characters of 



SeliastrcBa, and its septa and costse are exceedingly echinulate. 



Tbe species is Orbicella crispata, Dana,= TJlastrcea crispata, 



Ed. & H., and these are now the synonyms of Heliastrcea crispata, 



Dana, sp. The species is recent, and from the Indian Ocean.

Colony massive, short, convex, or subplane, fixed by a large 

 base. Corallites large, united by their well-developed costse. 

 Calices projecting above a common surface, whicb is formed of 

 much exotheca; and the costse, large, separate, shallow, circular in 

 outline. Columella well developed and spongy, or small and 

 papillary where free. Septa numerous and regularly crenulated. 

 Costse well developed, crenulated, confluent. Endotheca and exo-
