FOSSILS OF TIIK ACADIAN GliOUl', 



657 



Mr Ilartt recognises several other species of Paradoxides, but 

 lias not found time to work out their characters in detail ; and this is 

 rendered particularly difficult by the circumstance that the thin crusts 

 of these creatures appear to have suffered even more from distortion 

 than the other fossils imbedded with them. 



The descriptions above given, with the fact that some of the layers 

 arc perfectly loaded with fragments of Trilobites, will serve to show 

 the exceeding richness of this ancient fauna, and to indicate its 

 relations to Primordial life in other parts of the world. These 

 remarkable fossils deserve, however, much more full and detailed 

 illustration than that which I have been able to give them ; and 

 many additional species will no doubt be found.
