596 PATAGONIAN EXPEDITIONS *. ZOOLOGY. 



General color brown of varying shades, mottled with white and cinna- 

 mon and somewhat shaded with slaty above ; barred transversely white 

 and brown below. 



Head : Forehead and loral region white ; recurved hairs on lores. 

 Crown deep brown, the feathers narrowly edged with dirty white and 

 with tinges of cinnamon. A supraciliary stripe of dirty white reaching 

 from the white of the forehead to above the ear-coverts; this stripe is 

 marked with fine hairlike dusky lines. Cheeks and ear-coverts deep 

 brown like the crown and much streaked with buffy white and cinnamon. 

 Facial ruff of dark brown feathers, bordered broadly with white, almost 

 pure in tone. Occiput of white feathers, with heavy deep brown terminal 

 markings almost obscuring the main feather-color. 



Neck : Above and on the sides, much like the occiput in color and mark- 

 ing ; the chin and upper throat buffy or dirty white, obscured by narrow, 

 brown streaks ; feathers of the lower throat brown of a chocolate shade, 

 mottled and spotted with white. 



Back : Deep brown, many of the feathers edged with buffy white and 

 cinnamon, this character becoming more pronounced toward the rump ; 

 the upper tail-coverts white and in most individuals each feather has a 

 small but distinct bright cinnamon spot near its tip, while the lateral ones 

 are crossed by pale cinnamon bars. 



Tail : When closed, from above, slaty blue, crossed by from five to 

 seven narrow bars, and a broad subterminal band, all deep brown, each 

 rectrix being tipped narrowly with white. When spread, the tail is almost 

 like that of the immature male in blue plumage (p. 593) while seen from 

 beneath, it is very similar to the above described phase of plumage. 



Wings : The greater coverts slaty blue, broadly barred with deep 

 brown ; median and lesser coverts deep brown, with pale cinnamon or 

 buffy white edges and spots, the whole having a mottled look, except on 

 the shoulders, where the deep brown feathers are faintly edged with cin- 

 namon ; the scapulars are deep brown, barred with ashy grey and pale 

 cinnamon ; all the quills slaty blue, broadly barred with deep brown and 

 with the subterminal bar very broad and narrowly edged with white ; this 

 edging is wider and more distinct on the secondaries. Seen from below, 

 the quills appear white, with narrower deep brown bars and a broad sub- 

 terminal bar ; the inner webs are shaded with pale cinnamon or buffy. 



Lower parts : The chin and upper throat whitish, with a mid-streak of
