Description. 



Adult. Above, ashy umber, much as in calif ornicum, but up- 

 per tail-coverts and rump more rufescent. Head above with nu- 

 merous sharply defined longitudinal lines of clear white. Spots 

 of nuchal collar conspicuous. Scapulars with concealed, large 

 roundish spots of white ; lower wing-coverts with irregular white 

 spots. Secondaries scarcely darker than the back, crossed by 5 (ex- 

 posed) narrow bands of pale brown becoming white exteriorly ; pri- 

 maries darker than secondaries, outer webs with irregular spots, — 

 those beyond the sinuation of the quill nearly white, the basal ones 

 dull brown; there are seven on the largest quill. Tail, dark brown 

 (considerably darker than the primaries) with seven (d") to eight (?) 

 bands of pure white, the transverse spots forming these bands, not 

 touching the shafts of the feathers, though running out to the edge 

 of the web. Sides of the breast and stripes of the sides and lower 

 tail-coverts paler grayish brown than the color above.
