No. 5-] PARIOTICHUS INCISIVUS COPE. 245 



It will be seen that in many places the form here described 

 departs from Cope's description of the type Pariotichus incisi- 

 vus, but it seems best to assign it to the form which the 

 previous fragmentary description most nearly indicates, and 

 avoid the introduction of a new name until it may become 

 necessary.
