GULL.

beautiful white, except a few of the tail coverts, which are barred 

 with dusky. The young are blackish, and the old ones do not 

 become perfectly white under three years. 



Inhabits Hudson's Bay; is scarce along the coasts, but more 

 plentiful in the Islands, and inland lakes, where it makes a slight 

 nest on the ground, of dry grass, and lays four white eggs. This 

 was described to me by the late Mr. Hutchins, under the name of 

 Ivory Gull, but I suspect it to be a distinct species, as it so very 

 much exceeds that in size.
