" Description. — Above grayish bistre, rather darker on head, somewhat 

 more rufous on rump, the feathers there with more or less concealed 

 white spots ; upper tail-coverts hair brown, obscurely barred with black- 

 ish. Wings fuscous, the secondaries marked on external webs, the 

 innermost ones on both, with alternate bars of brownish olive and 

 blackish ; primaries indented basally on outer webs with buffy ; lesser 

 and middle coverts like the back; greater series barred on exterior webs 

 and tipped with this same color. Central rectrices and exterior webs of 

 all but outer pair like the back in color, but regularly barred with black; 

 tips of the feathers hair brown, indentations on distal portion of exter- 

 nal webs of outer pair dull white; remainder of tail black. Superciliary 

 stripe white; lores and cheeks grayish white mixed with dull brown; 

 postocular streak brownish olive; sides of neck brownish gray, under 

 surface dull brownish white, most nearly pure white on chin and throat; 

 sides washed with brownish gray, flanks strongly tinged with the same ; 

 under tail-coverts slightly washed with ochraceous and heavily barred 

 with black ; lining of wing grayish white. 



" This new subspecies may be distinguished from charienturus by the 

 darker, more rufescent coloration of the upper surface, sides and flanks ; 

 the tail also averages appreciably shorter. It is noticeably lighter and 

 rather more grayish than spilurus, besides having a somewhat longer 

 culmen. From drymcecus it is without difficulty separable by the notice- 

 ably darker and rather more sooty color of the flanks and upper surface. 

 The tail also averages slightly shorter."
