Delaware. 



Mr. W. J. Fox reported a few species from Bowers Beach, July 

 30 and 31. Dr. Thomas Barbour gave me a list of eight species he 

 met with off Ship John Light, August 19. With Messrs. Innes and 

 Dorsey I visited Wyoming Pond on August 20. This is formed 

 simply as a wide pond about a mile long, by the dam on the trib- 

 utary of Jones Creek called Wyoming Creek. The water is still 

 and very hard, the banks mostly of sand, shallow and sloping. 

 Along each bank we found wide growths of aquatic vegetation, 

 often as great mats of Ceratophyllum. In the more sheltered 

 small coves the water was often covered with a mantle of green 

 algae, duckweed, etc. Mr. G. MacReynolds sent some notes on 

 food fishes he captured at Delaware City and St. Georges in 1905, 

 interesting in comparison with present conditions. 



Carcharias taurus Rafmesque. About a dozen at Bowers Beach. 



Eulamia milberti (Muller and Henle). Small example at Ship 

 John. 



Sphyrna zygaena (Linne). Small one at Bowers Beach. 



Raja erinacea Mitchill. One at Bowers Beach. 



Dasyatis say (Le Sueur). One at Ship John. 



Ameiurus catus (Linne). Common at Delaware City and St. 

 Georges, reaching about 300 mm. At Wyoming Pond Ameiurus 

 nebulosus, Anguilla rostrata and Perca flavesce?is were reported 

 abundant. Morone americana was said to have been introduced 

 during the past few years, prior to which none were seen for twenty 

 years. 



Abramis crysoleucas (Mitchill). Abundant, all small, in Wyoming 

 Pond. 



Erimyzon sucetta oblojigus (Mitchill). Young very common 

 in Wyoming Pond. 



Esox americanus (Gmelin). One in Wyoming Pond. 



Esox tridecemlineatus Mitchill. Abundant in Wyoming Pond,
