 with ashy tips to the feathers; the quills all brown of the same tone, 

 shaded with ashy on their exposed surfaces ; the primaries whitish at base 

 and for two-thirds their length, this color obscured by minute flecking of 

 dull brown ; the shafts ivory-white ; the primary coverts white and flecked 

 to a less degree, and crossed by three indistinct brown lines, or narrow 

 bands ; the secondaries brown like the back, and, seen from above, very 

 obscurely barred, or spotted irregularly with dull cinnamon; all the quills 

 from beneath present a strong cinnamon tint on both vanes and this ground 

 color is barred distinctly and rather narrowly with dark brown ; under wing- 

 coverts and axillaries cinnamon, barred with dark brown in narrow bars 

 far apart.
