Larus marinus (47). Great Black-backed Gull. 



"Rare winter visitant along the New Jersey coast, a few, 

 however, probably occur every year" (Birds E. Pa. and N. J., 

 43). "Has been taken (including the adult) at Cobb's Island, 

 where on the authority of Capt. Crumb it is not common, 

 though seen every winter" (Birds Vas., 41) ; "south coastwise 

 in winter to Florida" (Key, p. 743). On January 27, 1895, 

 at Holly Point, I saw one of these birds circling over the 

 mouth of Gunpowder River, but it kept considerably out of 

 range. 



Larus argentatus smithsonianus (51a). American Herring 

 Gull. 



In Baltimore harbor this species is a common winter resident, 

 common over the Basin at Light and Pratt streets, where they 

 live on the refuse. During the latter part of September I 

 could not find any, but quite a number were at hand on October 

 5, ('94). On May 1, ('95), a number were observed, and on 

 May 6, ('95), two were in Canton Hollow. They also occur 

 on all our waters, but not in numbers as they appear in our 

 harbor. "Common in winter at Washington" (Richmond). 



Larus delawarensis (54). Ring-billed Gull. 



At Washington "seen over the river during the winter 

 months, more frequently than the Herring Gull" (A. C., 108). 

 "Winters abundantly -on the coast of the Middle States, I saw 

 it continually during two winters over the harbor of Baltimore 

 where it flies among the shipping, with Bonaparte's Gulls and 

 several kinds of terns" (Birds N. W., 638). 



However the above may have been when Dr. Coues was at 

 Fort McHenry, I have been unable to substantiate the state- 

 ment, a stray tern being of very unusual occurrence above the 

 Fort, while Bonaparte's Gull, as a rule, keeps below it. My only 

 spring notes are of two near Holly Point over Gunpowder River 

 on March 25 ('94), and a few in the lower harbor on March
