160 BRITISH FOSSIL CORALS. 
Middleham, Florence Court, and Arran, by Professor Phillips; in Derbyshire, at Kendal, 
in the Isle of Man, at Kulkrag in Fermanagh, at Clogher and Benburn, (Tyrone,) by 
Colonel Portlock, and in Belgium. <A specimen, in a very bad state of preservation, that 
belongs to the collection of the Geological Society, was met with in the Llandeilo Flags 
in Marloes Bay, and appears to be specifically identical with the above-described car- 
boniferous fossils. 
C. tumidus can easily be distinguished from the other species of the same genus which 
have a similar form, by the very small size of their calices, their thick margin, and almost 
circular form. 
We are inclined to think that the fossil described by Professor M‘Coy, under the 
name of Verticillopora dubia,’ may belong to this species. The Lamose milleporite of 
Parkinson,” appears also to be referable to it. This last-mentioned fossil was found in 
Wiltshire. 
2. Genus BEAUMONTIA.® 
1. Beavmontia Eczrtoni. Tab. XLV, fig. 1. 
Braumontta Eaurront, Milne Edwards and Jules Haime, Pol. Foss. des Terr. Palzoz., 
p. 276, 1851. 
Corallum forming a tall, lobate mass. Corallites basaltiform, somewhat flexuous, and 
showing distinctly costal striz under the epitheca. Calices very variable in size; the 
largest about three lines in diameter. Zwéule closely set, mostly horizontal, and very 
slightly convex, some incomplete and subvesicular. 
The specimen here described belongs to the collection of the Geological Society of 
London, and was found by Sir P. Egerton, at Sracrapagh, Fermanagh (Ireland). 
The genus Beaumontia has been established by us since the publication of the first 
part of this Monograph ; it is, therefore, necessary to mention here that it comprises the 
Favositidee with non-perforated walls and a more or less vesicular endotheca. This division 
has the same relation to Chaetetes as Michelinia has to Favosites. 
Beaumontia Eyertoni differs from B. venelorum* and B. laxa, by its tabule being 
mostly horizontal, and but very slightly convex. In a fourth species, #. Guerangeri,’ the 
calices are much more irregular, and smaller.
