Fowler — A List of the Fishes of Pennsylvania. 59 



Lycoming, Mifflin, Montour, Perry, Potter, Snyder, Somerset, Sullivan, 

 Wayne and York Counties. 



Genesee basin in Potter County. 



Ohio basin in Allegheny, Armstrong, Cambria, Clarion, Fayette, Indiana, 

 Jefferson, McKean, Potter. Somerset, Warren and Westmoreland Counties. 



Leuciscus margarita (Cope). Pearl Dace. 



One of Cope's six examples, originally obtained in the Conestoga near 

 Lancaster, 1 remains in the Academy. Ross records this species from Center 

 County, 2 though I have been unable to examine his material. 



Leuciscus carletoni Kendall. Carleton's Dace. 



A single example I obtained in high color July 23, 1899, in McKean 

 County at Cole Grove, is interesting as a new addition to the fauna. 3 It 

 was captured in a small mountain-stream, the surface of which was largely 

 covered with petroleum, so that the fish was not discovered until taken 

 out of the water in a net. Associated were a number of other small fishes 

 as creek chubs, silver-fins and cut-lips. Though I wrongly identified the 

 present example as the pearl dace, as indicated below, it agrees in every 

 way with the present species. 



Leuciscus vandoisulus Valenciennes. Rosy-sided Dace. 



Delaware, Elk and North East basins in Chester County. 

 Susquehanna basin in Cameron, Chester and Lancaster Counties. 



Leuciscus elongatus (Kirtland). Slender Dace. 

 Ohio basin in Crawford, Indiana and McKean Counties. 



Abramis crysoleucas (Mitchill). Roach. 



Delaware basin in Berks, Bucks, Chester, Delaware, Lebanon, Lehigh, 

 Monroe, Montgomery, Northampton, Philadelphia and Pike Counties. 



Susquehanna basin in Cameron, Lackawanna, Lancaster, Mifflin, Sulli- 

 van and York Counties. 



Ohio basin in Clarion and Elk Counties. 



Erie basin in Erie County. 



Ceratichthys vigilax Baird and Girard. Cliola Minnow. 

 Recorded from the Monongahela by Evermann and Bollman. 4 



Notropis bifrenatus (Cope). Bridled Minnow. 



Delaware basin in Berks, Bucks, Chester, Delaware, Lehigh, Mont- 

 gomery, Northampton and Philadelphia Counties. 

 Susquehanna basin in York and Lancaster Counties.
