Corallum dendroid ; its branches cylindrical, somewhat flexuous, scarcely ever 

 coalescent. Calices closely set, not prominent, much elongated transversely, or even 

 almost linear. The upper margin concave, and presenting a small medial process. The 

 under edge deeply emarginated in the middle, and presenting a small obtuse process on 

 each side. Ccenenchyma not very abundant. Diameter of the branches about 2 lines ; 

 large diameter of the calices about two fifths of a line ; and about four times their diameter 

 in the opposite direction. 



Dudley and Russia. Mr. Hall mentions its existence at Lockport, Niagara county. 



Specimens are in the Collections of Mr. Fletcher and M. de Verneuil. 



It is not without some hesitation that we place the genus Ccenites in the class of Polypi ; 

 the form of the calices resembling very much what is met with in certain Bryozoa. In 

 the present state of our knowledge concerning the structure of these fossils, their zoological 

 affinities cannot be determined with certainty, but we are inclined to think that they are 

 allied to the Favositidae. 



C. intertextui resembles C. juniperinus in its dendroid form, but differs from it in 

 the form of the calices.
