226 BRITISH FOSSIL CORALS. 
CYATHOPHYLLUM DAMNONIENSE, Milne Edwards and Jules Haime, Pol. Foss. des Terr. 
Paleeoz., p. 371, 1851. 
CysTIPHYLLUM _ M‘Coy, Brit. Paleoz. Foss., p. 71, 1851. 
Corallum simple, elongate, subturbinate, and almost straight. Sepa (100 or more) 
somewhat unequal in size alternately, closely set, very slender exteriorly, thick towards 
their inner part, and slightly curved. Déssepiments very closely set, vesicular, somewhat 
irregular, smaller and more numerous towards the outer part of the visceral chamber. 
Some small ¢aéule somewhat irregular, and very closely set, at the centre of the coral. 
Height sometimes 3 inches. 
Found at Torquay, Newton Bushel, Plymouth, and also, according to Professor 
Phillips, at Sharkham Point and Babbacombe. Specimens are in the collections of the 
Geological Society of London, of Dr. Battersby, and Mr. Pengelly. 
The fossil Coral designated by the name of CyarHopHYLLUM CELTICUM,' and found in 
the Devonian deposits of Cornwall and Devonshire,’ is as yet so imperfectly known that 
we are not able to characterize it m a satisfactory manner. The specimens met with are 
only natural casts from which the real coral has more or less completely disappeared ;_ they 
show, however, that the sep/a, (to the number of 36 or 48), must have been alternately 
of unequal size, and that the principal ones extended to the centre of the visceral 
chamber, where they became somewhat twisted. 
We have given the name of CyarnopHyiiuM Bucx.annr to a species which Professor 
M‘Coy described under that of Petraia gigas, but which is quite distinct from the 
Cyathophyllum gigas, previously described in MM. Yandell and Shumard’s Paper on the 
Geology of Kentucky, and therefore could not retain the same name. It is a simple coral 
like the preceding ones, and is known only by the casts it has left in the surrounding 
rock. ‘Till some better preserved specimens be met with, we therefore do not think it 
necessary to have this fossil figured in our Monograph.

Professor M‘Coy describes this fossil in the following terms :—“‘ Corallum elongate, conic, gradually 
increasing, (at an angle from the apex of about 30° externally), slightly oblique ; section apparently elliptical, 
the axes in the proportion of 70 to 100; internal cast obtusely conic, expanding at an angle of about 50° in
