60O PATAGONIAN EXPEDITIONS I ZOOLOGY. 



lighter markings about the face and each feather streaked broadly with 

 deep brown. The lighter color of the head varies in different individuals 

 from decided fulvous to nearly pure white and the brown areas vary in 

 the amount of cinnamon relieving them. 



Neck : Above and below deep brown, each feather broadly edged with 

 cinnamon, but not tipped with that color, the whole having a streaked or 

 striped appearance. 



Back : Mantle and lower back, as well as rump, deep brown, the feathers 

 narrowly tipped with bright cinnamon or pale fulvous ; this is most ap- 

 parent on the rump ; the upper tail-coverts vary from immaculate white in 

 some individuals to white heavily barred and marked with dull cinnamon 

 in others ; but the white patch is always conspicuous. 



Tail : Tail cinnamon or fulvous, except the two central rectrices, which 

 are slaty ash-blue, much as in the adults in the first breeding dress ; the 

 two central rectrices are crossed by five blackish brown bars and have a 

 broad subterminal band of the same color, being finally tipped with whitish 

 or fulvous ; the rest of the rectrices have the cinnamon or fulvous ground- 

 color, crossed by four dark brown or blackish bars, and by a broad sub- 

 terminal band, all having whitish or fulvous tips. Seen from below, the 

 tail presents a more ashy appearance, the fulvous or cinnamon shade 

 being obscured. 



Wings : All the quills dark brown, tipped with fulvous or dirty white ; 

 the primaries are shaded above on their outer webs with ashy slate, are 

 barred on both webs with deep brown, and, when seen from below, this 

 feature is most conspicuous, the inner webs being light in color and 

 shading into fulvous or pale cinnamon; all the upper wing-coverts are 

 deep rich brown, tipped broadly with bright cinnamon, or duller shades of 

 that color. 



Lower parts: Buffy cinnamon throughout, including the under tail- 

 coverts, the under wing-coverts and axillaries; this ground-color is 

 streaked with dark brown on the neck, chest, breast, sides and abdomen, 

 the effect of the bird, seen from below, or in front, being striped and not 

 barred; the cinnamon ground on the under tail-coverts and legs is barred 

 broadly with a shade of cinnamon-brown ; deep brown prevails on the 

 axillaries, barred with cinnamon ; the under wing-coverts are barred with 

 dull brown on a cinnamon ground, the whole having a mottled appear- 

 ance and being much like the same region in the birds in the first breeding 

 plumage.
