152 BRITISH FOSSIL CORALS. 



We have not seen any specimens of this fossil Coral, which constitutes, together with 

 the following species, a small genus nearly allied to Propora 1 and Lyellia? In a memoir 

 published in the 'Annals of Natural History' (1849), Professor M'Coy pointed out the 

 existence of infundibuliform tabulae as being one of its characters, and figured them very 

 distinctly in a woodcut ; but in his latter work, the same author represents the tabulae 

 as being horizontal, without explaining in the text the reason of this change.

" Cell-tubes two thirds of a line in diameter, and about their own diameter apart ; 

 their walls thick, of concentric layers, with closely placed funnel-shaped internal 

 diaphragms; interstices minutely vesicular; four to six rows of vesicular cells between 

 each pair of tubes. 



" Rare in the Carboniferous Limestone of Derbyshire." {M'Coy, loc. cit.) 



2. Genus Propora, (p. lix.)

" Discoid, convex ; surface with large, circular cells, in quincunx, about one third 

 their diameter apart ; sides of the cells radiatingly striated ; intervening flat spaces with 

 minute, irregular, curving ridges." [M'Coy, ' Carb. Foss. of Ireland,' loc. cit.) 



The fossil is known to us only by the figures and very brief descriptions given of it by 

 Professor Phillips, and more recently, by Professor M'Coy. It appears to be very nearly 

 allied to the Corals that form our genus Propora, and provisionally, at least, must be 

 referred to that group. It is the only species of Propora that has, as yet, been found in 

 the Carboniferous Deposits ; all the others belong to the Silurian Formation. 



Professor Phillips discovered this Coral in Northumberland, and Professor M'Coy 

 mentions its existence in Ireland, at Hook Point, Wexford.
