NOTES OX THE FAUNA ABOUT THE 

 HEADWATERS OF THE ALLE- 

 GHENY, GENESEE AND SUS- 

 QUEHANNA RIVERS IN 

 PENNSYLVANIA. 



During early June of 1906, the following fishes 

 were found in a tributary of the Allegheny near Port 

 Allegheny, in McKean County: 



Campostoma anomalum, Pi me pi tales notatus, 

 Semotilus atromaculatus, Rhinichthys atronasus, Hy- 

 bopsis kentuckiensis, Catostomus commersonnii, Bol- 

 eosoma nigrun and Etheostoma flabellare. 



The broad valley of this section offers more va- 

 ried conditions than the upper headwaters, which 

 are but small mountain brooks. Plethodon erythron- 

 otus, P. glutinosuSj Desmognathus fusca, both forms 

 of Diemictylus viridescens, Bufo americanus, Hyla 

 pickcringii, liana palustris, R. clamata, P. catesbei- 

 ana, R. sylvatica and Thamnophis sirtalis were also 

 found. Cryptobranchws alleganiensis was reported 

 to occur abundantly sometimes, though not met with 

 on this trip. 



In the summer of 1904*, Gyrinophilus porphyriti- 

 cus, Spelerpes bislineatus, Plethodon erythronotus, 

 Desmognathus fusca, Diemictylus viridescens, Bufo 

 americanus, Rana palustris, R. clamata, R. catesbei- 

 ana and R. sylvatica were found. All of these am- 

 phibians are typical of the hemlock forests. 



In the headwaters of the Genesee in Potter Co. 

 the following were found in June of 1906: Salvclinus 

 fontinalis, Semotilus atromaculatus, Rhinichthys 

 atronasus, Catostomus conimersonnii, Erimyzon su- 

 cetta oblongus, Ameiurus nebulosus Schilbeodes gy- 

 rinus and Cottus gracilis. Only Salvclinus and Rhin- 

 ichthys were found in the very small brooks or rills, 

 and this was also true of those in the Allegheny and 

 Susquehanna drainages. The Genesee Rhinichthys 

 was very dark, inclining largely to a dusky or black-
