Corallum, simple (sometimes two or three individuals are united by their bases, but 
their union is evidently accidental), turbinate, elongate, slightly curved, and presenting 
rather well marked growth swellings. Zpitheca very strong. Calice deep and with a 
thin margin; one or two rudimentary septal fossule. Sepéa 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 13 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. 
Cyathophyllum 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. pitheca 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
