from both in the enormous size of the septa and remarkable prominence and sharpness of the 

 rosta- of the first two cycles. The septa of these two cycles are even larger than those of 

 C. (Ceratocyathus) zanchca and compressa Seg. 



Corallum unattached, curved and slightly twisted, hardly compressed. 



Costa; ver)- thin, sinuous, those of the first two cycles extremely prominent and trenchant. 



Septa thin, wavy, denticulate, 48 in number in six regular systems : those of the first 



two cycles are equal, and are of enormous size and greatly exsert : those of the fourth cycle 



are a little larger and very much more exsert than those of the third : the surfaces of all are 



rather distantly papillose. 



Pali large, strongly sinuous, strongly but bluntly denticulate, 1 2 in number and placed 

 opposite the septa of the third cycle. 



The columella consists of three or four broad curly ribbons. 

 Soft parts brownish-yellow : corallum snow-white with a thin brownish epitheca.

This species also is related to C. communis Seg. and even more nearly to C.pumila Seg 



Corallum unattached (except when young) curved, hardly compressed. 



The costae in the larger specimens are merely discontinuous striations amid a field of 

 close-set but discrete miliary granules, but in the smaller specimens angular costae corresponding 

 with the first two cycles of septa are very distinct, at least on the convex curve of the corallum. 



Septa thin, 48 in number in six regular systems : those of the first two cycles, which 

 are equal, are conspicuously large and exsert : those of the 4 th cycle are about the same size 

 as, but are a little more exsert than, those of the 3 rd : the surfaces of all are denticulate, and 

 the edges, within the calicular fossa, a little sinuous. 



Pali strongly sinuous, bluntly denticulate, 1 2 in number and placed opposite the septa 

 of the third cycle. 



Columella of a few broad twisted ribbons, small. 



Soft parts brownish-yellow : corallum white, but much discoloured on the outside below 

 the calicular margin.
