Corallum dendroid ; its branches placed wide apart, not coalescent, and about half a 

 line in diameter. Calices somewhat oblique, deep, with the exterior part of their edge 

 rounded or subpolygonal ; walls thick ; some very small calices often situated between the 

 large ones, which are about two thirds of a hue in diameter ; a single line of large pores 

 on each side of the walls. 



Found at Torquay, and, according to Professor Phillips, at Lee Quarry near Combe 

 Martin ; West Hagginton ; Hillsborough near Ilfracombe ; Babbacombe, Hope, Sharkham 

 Point, Mudstone Bay ; in France, at Ferques (Pas-de-Calais), Vire, Chassegrain (Sarthe) ; 

 in Germany at Bensberg ; in America at the Falls of Ohio, and in the Clarke county. 



This coral differs from F. reticulata} and F. cervicornii by the obliquity of its calices, 

 — a character which gives it some resemblance to Alveolites. 



The only British specimen of this species that we have seen belongs to the collection 

 of the Geological Society, but is in too bad a state of preservation to be worth being 

 represented in the plates joined to this Monograph.

Corallum massive, very convex ; sometimes subpyriform or sublobate. CoralUtes 

 prismatical, radiating from the base of the corallum to its surface ; straight, or slightly 

 flexuous, and almost equal in size. Tabula very closely set (12 or 15 in the space of a 

 line). Mural pores large in proportion to the size of the corallites, closely set, alternating 

 with the tabulae, and arranged in single vertical lines at the angles of the prismatical walls. 

 Diameter of the calices about one tenth of a line. 



Found in the Devonian formation at Torquay, and, according to Mr. Phillips, at 

 Darlington near Totness, Sharkham Point, and Babbacombe ; in France, at Vire (Sarthe) ; 

 in Germany in the Eifel and in the Hartz Mountains. Found also in the superior
