much darker ; the ends of the primaries and the ends of their shafts 

 black, their tips white, of which color are the eyelids ; feet carmine. 

 Length fourteen inches and a half, wing ten and a quarter. Young 

 with the forehead white ; crown and upper portion of the hind 

 neck, mottled with dusky ; other parts of the neck white, tinged 

 with grayish-blue ; lower parts white ; tail the same color, with a 

 terminal band of black, which disappears after the second moult ; 

 neck and wings grayish-blue, with a few spots of bi-own on the lat- 

 ter; a spot of dusky on either side of the neck, which is a strong 

 distinguishing character for the young of this species. 



In plumage this species resembles L. atricilla, but differs ma- 

 terially in size as well as in the color of the bill. With us, during 

 some seasons, the young are quite common, though the adult is by 

 no means so. It is a handsome and strongly marked species, and, 

 when flying, utters a peculiar shrill and rather plaintive cry.
