J 10 ON THE FOSSIL CORALS OF THE 



Fatosites Ceeyicoenis. — (De Blainville.) 

 This species is one of those included by Groldfuss in his Fawsites 

 polymorpha. The specimen represented by fig. 9 agrees very well 



Fig. 9. — F. cervicornis from Wainfleet, 0. "W. 



"with those figured in the Peirifacta Geronanice, pi. 27, and also with 

 that of Edwards and Haime, British Fossil Corals, pi. 48, fig. 2. "We 

 have other specimens in which the cells are on an average from half 

 a line to one line in width, which cannot be separated from the one I 

 have figured. In some, the branches are nearly two inches in dia- 

 meter, and in consequence of the thickening of the walls, the aper- 

 tures of the cells are often perfectly circular. 



Locality and formation. — ^Eama's farm, lot 6, con. 1, Wainfleet, and 

 near Cayuga, C. "W. 



Pavosites poltmoepha. — (Goldfuss.) 

 These small branching corals have been referred to several species 

 supposed to be distinct by some authors, while according to Mr. 

 Lonsdale and Professor McCoy, they all belong to one natural group, 

 of which the proper appellation is F. polymorpha, Goldfuss. In their 

 description of F. reticulata, British Fossil Corals, p. 216, Edwards 

 and Haime, also have the following remarks :
