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 LARID^E 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 Berk's County, mounted a young 'Kittiwake 

 which had been captured near Lancaster City, in midwinter," and 

 "Dr. A. C. Treichler, of Elizabeth town, 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 to a 

 description of this bird, which I sent to Mr. Robert Ridg way, 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 

 L. 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."
