127. Limosa uropijgialis Gould. (549a.) Very common at the 
Yukon mouth, and on the Pastolik marshes to the north of it. The largest 
snipe found in the country. Lays two light olivaceous-spotted eggs, in a 
rounded depression in a sedge tussock, lined with dry grass. Very good

agreed well with the colors and crest of the lapwing, I am induced to 
believe that stragglers of that species may occasionally occur there.
