BAM. LAR TDZE. 
GUILIES, DERNS: 
LARUS ATRICILLA. Linn. 
LAUGHING GULL. 
Adult Male.— Bill, lake red; hood, grayish black; nape, white, 
forming a sort of collar; upper parts, pearl-gray; beneath, white ; 
outer primaries, dark brown; tail, white; feet, black, with red on 
the webs; iris, dark brown. 
Length 15.50, wing 12.50, tail 5, tarsus 1.90, bill 1.40. 
About the time that the visitors who have been spending the 
winter at Nassau begin to leave for the north, the Laughing Gull 
appears, and may be daily seen passing in and out among the 
numerous vessels anchored in the harbor. We found it abundant 
throughout the whole of the Bahamas after April, and at Inagua it 
was evidently breeding, although our search for its eggs proved 
unsuccessful.
