lambe. ] CANADIAN PALAEOZOIC CORALS. 197 



This coral has structural characters of so peculiar a nature as to pre- 

 clude its being referred to any described geuus known to the writer. 

 The combination of well developed tabulae enclosed within a distinct wall 

 surrounded by vesicular tissue, is certainly most curious as well as inter- 

 esting, more particularly when the absence of septa is considered. The 

 name of the new genus founded for the reception of this Corniferous 

 coral, is suggested by the locality from which the specimen was obtained. 



The absence of septa and the strong development of vesicular tissue 

 suggest affinities to Cystiphyllum, and for the present at least Cayugcea 

 is placed with the Cystiphyllidce.
