Stercorarius parasiticus (37). Parasitic Jaeger. 
Winters along the Atlantic coast from the middle states 
southward. 
Stercorarius longicaudus (38). Long-tailed Jaeger. 
Migrates south along the Atlantic coast to the Gulf of Mex- 
ico and West Indies. 
No doubt all three of the Jaegers occur off our coast, but we 
have no record of them. 
Family Larrp#£—Gulls and Terns. 
Rissa tridactyla (40). Kittiwake. 
“Very rare winter visitant on the New Jersey coast” (Birds 
E. Pa. and N. J., 42). “ About ten years ago the late Henry 
B. Graves, of Berks County, mounted a young Kittiwake 
which had been captured near Lancaster City, in midwinter,” and 
“Dr, A. C. Treichler, of Elizabethtown, mentions the species 
as a straggler in Lancaster County, Pa.” (Birds Pa., 17). 
“Captain Crumb reports this species as a rare and irregular 
winter visitant at Cobb’s Island, but he has never taken a spec- 
imen” (Birds Vas., 41). 
Larus leucopterus (43). Iceland Gull (?). 
On November 23, 1893, I saw a pure white gull in the in- 
ner harbor of Baltimore City. It came within fifty feet of me 
at. times, as I watched it for fully half an hour. In reply toa 
description of this bird, which I sent to Mr. Robert Ridgway, he 
writes: “The gull which you think may be the young of L. 
leucopterus, is undoubtedly what American ornithologists here 
consider and describe as the young of that species. There is a 
question, however, whether it is not in reality the young of 
LL. kumlieni. There are no present means of settling the. 
question, there being no specimens of undoubted young of L. 
leucopterus in any American collection so far as I know.”
