Corallmn, simple (sometimes two or three individuals are united by their bases, but 

 their union is evidently accidental), turbinate, elongate, slightly cm-ved, and presenting 

 rather well marked growth swellings. Epitheca very strong. Calice deep and with a 

 thin margin ; one or two rudimentary septal fossulae. Septa delicate, alternately larger 

 and smaller but not differing much in size, narrow at their upper end, straight, and not 

 extending quite to the bottom of the central fossula which, as well as the interseptal loculi, 

 is somewhat vesicular. The number of the septa varies, according to the size of the corals, 

 from 60 to 120. The large individuals are sometimes 6 inches wide, with the calice 

 about 3 inches in diameter, and 1^ or two inches deep, but most specimens are not more 

 than two inches in diameter. 



Found at Torquay, and according to Prof. M'Coy, at Newton Bushel. In the Eifel 

 Mountains in Germany. 



The only British specimen of this species that we have seen is the one figured in this 

 Monograph ; it is a young individual in a very indifferent state of preservation. 



Cyatliophyllum ceratites differs from the other simple species of the same generical 

 group by the depth of its calice, its rudimentary septal fossula, and its septa being almost 

 equally developed.

Corallum simple, conical, elongated, curved, and free. Epitheca presenting some 

 prominent folds, principally on the side of the convex curve. Calice almost circular, 

 large and deep, 74 or more. Septa alternately somewhat thicker or thinner, very closely 

 set, not exsert, denticulated, narrow, slightly arched at their upper edge, and extending to
