GASTEROSTEID.^. 

 Eucalia inconstans (Kirtland). Brook Stickleback. 

 I obtained it in the Allegheny at Foxburg. 



Gasterosteus aculeatus Linnaeus. Two-spined Stickleback. 

 I have no local material, though it has been recorded from the Delaware 

 at Philadelphia by Dr. C. C. Abbott.' It must be rare or extremely local 

 in our limits, as I never met with it away from the coastal region, or far 

 from salt water. To the contrary the late Dr. Bean says "in Pennsylvania 

 Mr. Seal has found this fish abundant in pools and ditches along the Dela- 

 ware," a statement^ which in every way agrees with my knowledge of 

 Apeltes quadracus. 



Apeltes quadracus (Mitchill). Three-spined Stickleback. 

 Delaware basin in Bucks, Delaware, Lehigh, Northampton and Phila- 

 delphia Counties. Jordan and Evermann state "male almost black; 

 ventralswith the membrane red in spring," though of the countless spawn- 

 ing examples I have examined never a black male has been seen, and most 

 all the males at every season of the year had red ventrals. 



APHREDODERID^. 

 Aphredoderus sayanus (Gilliams). Pirate Perch. 

 Delaware basin in Bucks, Delaware and Philadelphia Counties. 



MICROPTERIDiE. 

 Pomoxis annularis Rafinesque. Crappie. 

 Reported from the Monongahela and my material from the Kiskiminitas 

 River. Likely introduced in the Delaware and Susquehanna basins, 

 where frequently met with. 



Pomoxis sparoides (Lac^pede). Calico Bass. 

 Delaware basin in Bucks, Delaware, Monroe, Montgomery, Northamp- 

 ton, Philadelphia and Pike Counties. 



Susquehanna basin in Lancaster and York Counties. 

 Ohio basin in Clarion County 

 Erie basin in Erie County. 



Ambloplites rupestris (Rafinesque). Red-eyed Bass. 



Ohio basin in Beaver, Clarion, Fayette, Indiana, Lawrence, McKean, 

 Warren and Westmoreland Counties. 



Genesee basin in Potter County. 



Erie basin in Crawford and Erie Counties. Introduced in the Delaware 

 and Susquehanna basins.
