•464 THE CANADIAN NATURALIST. [Vol. ix. 



Hitherto the most characteristic species obtained from it have 

 been the reptile Bathygnathiis horealis and fossil wood of a type 

 elsewhere found in the Mesozoic. These are, however, sufficient 

 to distinguish it from the underlying Permian. The fossils now 

 referred to are species belonging to the latter, but found in beds 

 heretofore referred to the Trias. The inference would be that 

 the Permo-carboniferous formation is more extensively distri- 

 buted on the south side of Prince Edward Island than has been 

 supposed. 



The following section observed at Rice Point and vicinity, 

 shows the nature and arrangement of the beds affordins; the fos- 

 sils referred to :
