Primaries, secondaries, most of the wing-coverts, and the remnants of the feathers 

 covering the tarsus, white, more or less soiled and abraded, except the new feathers 

 in the win-8. Forehead and crown black, with ferrugineous brown edging; chin 

 smoky blac\, with whitish edging. Middle of breast and abdomen, mcluding the 

 peculiar loose and downy feathering of the latter, and the tibiae, smoky black, the 

 latter whitish at the base and somewhat grayish at the tips, giving these parts a 

 cloudy appearance. The remaining plumage, including the under tail-coverts, dis- 

 tinctly crosswise vermiculated with black and saturated ferrugineous brown, except 

 on the longest upper tail-coverts, and the sides of the abdomen where the design is 

 so indistinct as to become a fine mottling only ; in some of the feathers of the back 

 the terminal or subterminal brown is of a somewhat lighter shade. Tail-feathers 

 black to the base, and the white tips wholly worn away. The inner primaries are 

 new and not yet fully out. They have blackish shafts, while those on the three first 

 priuiaries, still left from the foregoing winter plumage, are almost wholly white.
