FISHES OF THE POQUESSING CREEK 



HENRY W. FOWLER 



This little tributary of the Delaware is one 

 of the most interesting of our smaller streams. 

 It forms the upper boundary of Philadelphia, 

 draining the country between the Pennypack 

 and Neshaminy basins, though of greatly 

 smaller area. But a very short portion of its 

 lower course is tidal and, therefore, but few 

 tidal or lowland species occur. The upper 

 waters are characteristic of the . Piedmont 

 fauna. As many of these species are of in- 

 terest to aquarium students, I give the fol- 

 lowing list, with the localities at which they 

 have been observed. 



ALEWIFE (Pomolobns pseiidoharengus). 

 Occurs at Torresdale, in tidal waters, some- 

 times during the spring runs. 



EEL (AnguUla chrisypa). Torresdale. A 

 large one was taken many years ago above 

 Red Lion. 



FALL-FISH (Semotilus bidlaris). Com- 

 mon, especiallv the young, near Red Lion, 

 Andalusia, Knight's Mill; also in Bj^berry 

 Creek and Walton Run. 



ROACH {Abrmnis crysoleiicas). Torres- 

 dale. 



BRIDLED MINNOW (Notropis bifrenatus). 

 Andalusia and Torresdale. 



SILVER-FIN (Notrovis whipplii aiialo- 

 stanus). Common at Red Lion, Andnlusia, 

 Knight's Mill, and in Byberry Creek and Wal- 

 ton Run.
