562 PATAGONIAN EXPEDITIONS! ZOOLOGY. 



Tail : Dirty yellowish white, with fourteen or more rather obsolete bars 

 of pale ashy brown and a broad terminal band, an inch and a quarter, of 

 the same color. 



Wings : Primaries, pale ashy brown for the terminal third ; the other 

 two-thirds whitish, more or less distinctly vermiculated and obsoletely 

 barred with pale ashy brown ; secondaries nearly the shade of the upper 

 back, barred with rusty brown of a lighter shade and tipped with dirty yel- 

 lowish white ; tertials much like the secondaries, but with more pro- 

 nounced yellowish white terminally ; upper wing-coverts dull brown, the 

 feathers becoming paler at the ends and often buff in splotches, giving to 

 the whole an irregular mixed brown and dull buff appearance ; under wing- 

 coverts and axillaries deeper seal-brown. 



Lower parts : Dull brown, each feather with a distinct median stripe 

 and an irregular terminus of dirty buff, in some parts nearly obscuring the 

 pattern ; the thighs and flanks darker brown and obsoletely and faintly 

 barred with dull buff; under tail-coverts dirty white, with some obscure 

 brown barring on those nearest the vent. 



Bill : Grey horn-color ; the cere orange-yellow. 



Iris : Hazel-brown. Bare crop-patch orange-yellow. 



Feet: Yellow obscured by lead-color, which prevails on the tarsi. 



Downy young : Covered with a dull white down, often buffy in tone.
