158 BRITISH FOSSIL CORALS, 



This coral is found at Corwen, near Bristol, and has also been met with at Lee, in 

 Northumberland, by Mr. Phillips, in Westmoreland, in Derbyshire, and in Ireland, by 

 Professor M'Coy, and at Novogorod, in Russia, by M. Keyserling. Specimens are in the 

 Museum of Practical Geology, the Bristol Museum, &c. 



The fossil mentioned by Colonel Portlock, under the name of Favosites fibrosa, 1 and 

 found by that geologist at Armagh, Donaghenry, and Derryloran, in Ireland, appears to 

 belong to this species.

Coral much resembling the preceding species, but having the calices much smaller and 

 less irregular. Diameter of the corallites one tenth or one eighth of a line. 



The specimens here described were found near Bristol, and in Salop, and were 

 communicated to us by the directors of the Bristol Museum and Museum of Practical 

 Geology. The existence of the same fossil is mentioned by Mr. Phillips, at Gordale 

 and Ribblehead, by Professor M'Coy, at Kendal, Westmoreland, by Col. Portlock, at 

 Armagh, and by M. Keyserling, in Petschora.
