CLADOCORA M.-Edw. & H. 



Caryophyllia (pars) Lamk. 

 •ora ( [Kirs) Eiirbg. 

 Caryophyllia (pars) Dana. 



Cladocora brevis Pourt. 



Corallum forming a dense cluster, the corallites rising in part from 

 an expanded base, but chiefly budding from the wall at a very open 

 angle. No epitheca, or only a false one, at the base of the clusters. 

 The corallites very short (5 to 6 mm.), with finely granulated costae 

 distinct to the base. Fossa rather deep. Septa rounded above, slightly 

 exsert, minutely serrate ; the fourth cycle developed in one half of 

 each system generally. Pali well developed and at different distances 

 from the centre. Columella a rather dense mass of papillae with con- 

 cave surface. Diameter of calicle 3.5 to 4 mm. 



Florida Reef, rare. 



This species resembles C. parvistella Duch. & Mich., but differs from it 

 by its fuller development of the fourth cycle, larger size of calicles, 

 more complete pali, etc. The general appearance is very much like 

 Cladocora muMcauUs M.-Edw. & H. (Lithodendron multicaule Michelin), 

 but it has smaller calicles. 



Cladocora arbuscula M.-Edw. & H. 



Carijophijllia arbuscula Lesueck. 



Very abundant ; it is found in quantities on muddy shoals, in com- 

 pany with Pontes furcata, and extends downwards to about 13 fathoms.
