Hog Fish. Sand Perch. 
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.
