 and median terminal spot of the same; primaries clove brown, the inner 

 webs uniform, the outer ones barred with pale pinkish buff to pale 

 ochraceous-salmon ; upper back just posterior to the interscapulars dark 

 fuscous-black edged and barred with narrow lines of auburn, the bars 

 widely spaced ; back and lower back pale huffy brown with a slight olive 

 tinge, each feather with several small black subterminal flecks ; lower back, 

 rump, and upper tail coverts similar but darker — cinnamon-brown on the 

 rump and darkening posteriorly to dark cinnamon-brown, the feathers of 

 the rump and the upper tail coverts finely vermiculated with blackish, 

 the black flecks extended laterally to form somewhat heavier wavy bars

 rectrices clove brown to dark mummy brown crossed by widely spaced 

 narrow bars pale cinnamon-brown; lores and circumocular area bare, 

 crimson in life; an indefinite band from the forehead over the eye to 

 the upper side of the auriculars dark auburn; cheeks and auriculars 

 brighter auburn; chin and line of the gape narrowly paler auburn; 

 throat, breast, and sides cinnamon-brown, slightly washed with olivaceous 

 anteriorly, the feathers of the throat slightly duskier subterminally ; those 

 of the breast and sides subterminally narrowly banded with one or tw9 

 bands of blackish, the more posterior feathers with these bands heavier 

 and distally edged with pale cinnamon-brown to almost whitish; flanks 

 like the sides but more heavily and coarsely marked with black and pale 

 subterminally ; middle of abdomen dull buffy brown with indistinct dusky 

 cross bars, darkening posteriorly to almost olive-brown ; thighs dark olive- 

 brown indistinctly barred with cinnamon-brown under tail coverts olive-
