'909.] THE CAYUGA LAKE BASIN, N. Y. 413 



Sometime during the spring of 1864, near a marsh on Cayuga Lake, two 

 large birds were seen for several weeks, but one of them left a few days 

 before the other was killed. None of the hunters had ever seen anything of 

 the kind about here before. It proved to be a specimen of the white or 

 rough-billed pelican (Pelecanus erythrorhynchus Gmelin), in good condition, 

 and its wings measured fully eight feet from tip to tip. 



In the late summer about 1888 Foster Parker killed a specimen which 

 is now in the New York State Museum.
