Hiodon tergisus Le Sueur. Moon-eye. 



Originally described from the Ohio at Pittsburgh, 1 though no recent 

 records given. I found it at Erie. 



DOROSOMID.E. 

 Dorosoma cepedianum (Le Sueur). Mud-shad. 

 Only recorded from the tidal of the Delaware basin, (Andalusia) Bucks, 

 Chester, Delaware and (Bridesburg, Tacony) Philadelphia Counties. Le 

 Sueur originally 2 obtained it in the "market of Philadelphia." 



CLUPEIDjE. 

 Pomolobus chrysochloris Rafinesque. Inland Alewife. 

 Known from Rafinesque's original account, 3 which gives it from the Ohio 

 River and also says "it seldom goes as far as Pittsburgh." "Herring" re- 

 ported formerly in (the Conemaugh River) Indiana County were likely this 

 species. 



Pomolobus mediocris (Mitchill). Fall Herring. 



I have no local material though include this species provisionally, or 

 only on reports of its occurrence in the Delaware River tidal of Bucks 

 County at Tullytown. In late October, 1906, a school of about fifty large 

 examples were reported at this point. When swimming at the surface they 

 produced quite a disturbance, somewhat like a school of menhaden. About 

 eight were taken on hooks baited with our common river killifishes (Fun- 

 dulus), which were fastened to the hook by the upper jaw. When opened 

 the herring were found more or less gorged with killifish. They took the 

 bait with a rush and greatly interested the local anglers who called them 

 "jacks" or "skipjacks." They remained until November. A large herring 

 taken at the same place in December, 1912, was doubtless the same species 



Pomolobus pseudoharengus (Wilson). Alewife. 



Delaware basin, (New Hope) Bucks, Delaware and Philadelphia Counties. 



Susquehanna basin, (Harrisburg) Dauphin, (reported at Clarke's Ferry 

 dam in North Branch 4 ) Lackawanna, (Bainbridge, Fite's Eddy, Marietta, 

 McCall's Ferry, Pequea, Safe Harbor) Lancaster, (Marysville) Perry and 

 (McCall's Ferry, Peach Bottom and York Furnace) York Counties. 



Pomolobus aestivalis (Mitchill). Summer Herring. 



Only found in the Delaware basin in Bucks, Delaware and Philadelphia 

 Counties.
