Adult male. — Forehead narrowly white or pale bufify white; crown 

 slate-gray to slate color; occipital crest of long narrow black feathers; 

 rest of occiput, nape, and anterior interscapulars similar but heavily

 slate color) ; rest of interscapulars, back, lower back, rump, upper tail 

 coverts, and upper wing coverts dark olive-brown ; innermost secondaries 

 and their greater upper coverts similar but internally edged with white

 outer webs ; rectrices fuscous very finely speckled and vermiculated with 

 olive-brown; lores and narrow superciliary stripe white; chin white; 

 throat and cheeks dark bright chestnut becoming blackish under the 

 eye, posterior to the lores, and on the posterior edge of the cheeks and 

 throat, a broad white line from the eye runs posteroventrally to the latero- 

 posterior corner of the throat separating the chestnut area from the slate- 

 gray to slate-color sides of the neck and of the breast; posterior breast 

 feathers slate-gray to slate color very broadly tipped with dark bright 

 chestnut ; sides of lower breast and upper and lateral parts of abdomen dark 

 bright chestnut broadly barred with white, the white bars often proximally 

 edged with blackish brown; flanks tawny-russet with concealed, sub-

°" Doubtfully distinct. This race is an intermediate group combining characters of 

 picta and of confinis. In series it can be made out as a faintly marked aggregate.
