"Description. — Above uniform dull rufescent hair brown, the rump 

 with more or less concealed white spots, the tail-coverts slightly grayer 

 than the back, obsoletely barred with darker brown. Wings fuscous; 

 innermost secondaries and outer webs of remainder broadly barred with 

 the color of the upper surface and somewhat with blackish ; wing-coverts 

 like the back; primaries edged basal ly with buffy. Middle rectrices 

 hair brown, barred with black; exterior webs of succeeding p'air and 

 basal portion of exterior webs of remainder, excepting outermost pair, 

 like the middle feathers; outer pairs tipped with dull gray, external 

 webs of outermost pair indented terminally on exterior web with white; 

 tips of the other feathers hair brown; rest of tail black. Superciliary 

 stripe white; lores and cheeks white, somewhat mingled with brown; 

 postocular streak like the crown; sides of neck pale brownish gray; 

 lower parts grayish white, adventitiously washed with brownish, lightest 

 on the throat, the flanks and sides tinged with smoke gray; this deepest 

 on the former ; under tail-coverts tinged slightly with ochraceous, and 

 barred with black; lining of wing grayish white." 



" Thryomanes b. drymcecus may be distinguished from T. b. charien- 

 turus by rather paler, decidedly more rufescent flanks and upper surface, 

 together with somewhat shorter tail. Compared with eremophilus, it 

 is darker, more rufescent above, with a somewhat more prominent 

 superciliary stripe, and decidedly shorter wing and tail. The charac- 

 ters which separate drymcecus from cryptus consist in rather darker 

 flanks and upper surface, rather more conspicuous superciliary stripe, 

 somewhat more heavily and regularly barred crissum, much shorter 

 wing and tail. It differs from leucophrys in much more rufescent color 

 above, more heavily barred crissum, and much shorter culmen."
