226 BRITISH FOSSIL CORALS. 



Cyathophyllum damnoniense, Milne Edwards and Jules Haime, Pol. Foss. des Terr. 



Palseoz., p. 371, 1851. 

 Cystiphyllum — M'Coy, Brit. Palseoz. Foss., p. 71, 1851. 



Corallum simple, elongate, subturbinate, and almost straight. Septa (100 or more) 

 somewhat unequal in size alternately, closely set, very slender exteriorly, thick towards 

 their inner part, and slightly curved. Dissepiments very closely set, vesicular, somewhat 

 irregular, smaller and more numerous towards the outer part of the visceral chamber. 

 Some small tahulm 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 Cyathophyllum 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 in 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 septa, (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 Cyathophyllum Bucklandi 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 

 hke 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
