This, the largest of the darters, may be distinguished from 

 our other species by the broad interorbital space and pig-like 

 projecting snout. 



I have never seen any New Jersey examples. Dr. Abbott re- 

 ports it, however, and states that his specimens were pronounced 

 by Haldeman himself to be identical with those named Percina 

 nebulosa from the Susquehanna basin.
