NOTES ON A COLLECTION OF FISHES FROM THE 

 HEAD OF CHESAPEAKE BAY. 



BY LEWIS RADCLIFFE AND W. W. WELSH.* 



In the course of an investigation for the Bureau of Fisheries 

 in the spring of 1912, in the head of Chesapeake Bay and 

 vicinity, opportunity was afforded to make a small collection of 

 the fishes of the region. The territory covered included the 

 Susquehanna River from Port Deposit to its mouth, the North- 

 east River, the Elk River and its tributary, the Bohemia, the 

 Sassafras River, the Susquehanna Flats, and Chesapeake Bay 

 south to a line from Howell Point to Stony Point. From April 

 8th to May 8th the numerous pound-nets were visited almost 

 daily, and many visits were made to the several large seines in 

 operation during this time. Small collecting seines were also 

 used in Heron Run and the old canal (here connected with the 

 river by a break in the bank) at Lapidum, near Port Deposit, 

 Maryland; in Swan Creek, the Elk and Bohemia rivers, the 

 Sassafras River and Turner's Creek, and at the Bureau of 

 Fisheries station at Battery Island, 31 miles below Havre-de- 

 Grace, Maryland. 



In June, 1882, Dr. Tarleton H. Bean made a small collection 

 of fishes in this region, the results of which were published in 

 the Proceedings of the U. S. National Museum, Vol. VI, 1883, 

 pp. 365-367.
