Adult male. Similar to that of N. crecca, but the whitish line 

 which surrounds the green patcli on the sides of the head, and passes 

 down to the base of the bill, is almost obsolete ; the scapulars are 

 uniform pale slate-grey, with no white, and there is a broad whitish 

 crescent on each side of the breast in fi'ont of the shoulder. 



Female. Apparently indistinguishable from that of iV. crecca. 



Hah. Northern America, from Alaska and Greenland, to Mexico, 

 Honduras, and the West Indies : accidentally in Europe.
