270 BRITISH FOSSIL CORALS. 



From Wenlock, Benthall Edge, Gleedon Hill; Ardaun and Cong, Galway (M'Coy). 



Specimens are in the Collections of the Museum of Paris, of the Museum of Practical 

 Geology, of the Bristol Museum, of the Geological Society, of Mr. Fletcher, of Mr. J. 

 Gray, &c. 



This fossil was placed by Mr. Lonsdale in the genus Monticularia (Hydnophora), 

 which it resembles in some of its exterior characters ; but it differs most essentially, not 

 only from Hydnophora, but also from all the other corals belonging to the large family of 

 the Astraeidse, by existence of its well-developed tabulae, and rudimentary state of the septal 

 apparatus. This mode of structure is characteristic of the group of Favositidae. It has 

 great affinity with Chsetetes, but differs from that genus by the mode of termination of its 

 walls, and constitutes, in our system of classification, a new generical division, which we 

 have dedicated to our celebrated friend, Sir Henry de la Beche, to whom geology in 

 general, and more especially the geology of England, is most deeply indebted.
