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’ and Lyellia.” Tn a memoir 
published in the ‘Annals of Natural History’ (1849), Professor M‘Coy pointed out the 
existence of infundibuliform tabule as being one of its characters, and figured them very 
distinctly in a woodcut ; but in his latter work, the same author represents the tabulze 
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.” (J/‘Coy, loc. cit.)

“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.” (J/‘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.
