406 ANATID^. 



reddish-brown, each feather crossed with minute zigzag 

 blackish lines, some of the elongated scapulars falling over 

 the wing-coverts ; lower part of the back hair-brown ; upper 

 tail-coverts brown, barred with pale brown ; tail-feathers 

 uniform brown, slightly elongated and jjointed ; wing- 

 coverts white, slightly varied with brown ; the greater 

 coverts tipped with black ; the primaries uniform brown ; 

 the outer webs of the secondaries forming a green specu- 

 lum, tipped with black ; outer webs of the tertials blackish- 

 brown, inner web hair-brown ; lower part of the neck in 

 front reddish-brown, extending along under the wing to the 

 flanks, which are barred with dark lines ; breast, belly, and 

 vent white ; under tail-coverts brownish-black ; legs, toes, 

 and their membranes dark brown. The whole length is 

 nineteen inches. From the carpal joint to the end of the 

 wing ten inches ; the second quill-feather the longest in the 

 wing, but the first almost as long. 



The female has the whole head and neck yellowish-white, 

 thickly speckled with black, very little rufous on the breast ; 

 the back is dark brown. The young males, as usual, are 

 much like the females during the first season, but the 

 colours are more pronounced and the wing-pattern better 

 defined. They are subject to a regular change every spring 

 and autumn. 



The lower part of the trachea, here introduced from 

 Audubon's work, is, as noticed by Blyth, of small size, and 

 decidedly diiferent in form from that of the European Wigeon.
