coloration is not so bright. From P. ruficaudatus (Berlepsch) they 

 differ only in the tail being browner and distinctly barred. The 

 exact relationships of the various members of this group are involved 

 in much obscurity, which the material I have examined is insufficient 

 to dissolve, but it would not be surprising if P. macrurus should turn 

 out to be only subspecifically separable from P. mystacalis. 



Troglodytes solitarius sp. now 



Type, No. 37,359, Collection Carnegie Museum, adult male; 

 Paramo de Rosas, Estado Lara, Venezuela, March 21, 191 1 ; M. A. 

 Carriker, Jr. 



Description. — Above plain brown (between mummy-brown and 

 Prout's brown), becoming more rufescent on the upper tail-coverts; 

 wing-coverts like the back; wings dusky black, the outer webs of the 

 remiges with brown spots, giving the effect of bars in the closed wing, 

 the tertiaries with both webs thus barred; tail grayish brown, irregu- 

 larly barred with dusky black, as are also the longer upper tail-coverts; 

 a broad buffy superciliary stripe, separated from the buffy (and more 

 or less rufescent) cheeks by a broad postocular patch of rufescent 

 brown; orbital ring (incomplete posteriorly) buffy white; cheeks with 

 some dusky mottling; below dull white, the throat, breast, and sides 

 tinged with buffy; flanks wood-brown; under tail-coverts white or 

 buffy white, conspicuously barred with dusky black; under wing- 

 coverts pale buffy; "iris brown; feet light brownish horn; bill black, 

 whitish flesh-color basally below."

Remarks. — This very distinct species seems to find its nearest 

 relatives in T. solstitialis Sclater and T. ochraceus Ridgway. From 

 the former it differs in being without any trace of barring below 

 (except on the under tail-coverts), and from the latter in its much 

 larger size, different proportions, whiter under parts, and deeper 

 rufescent color above. Like the other members of this group, it is 

 apparently confined to the higher elevations of the Venezuelan Andes, 

 the three examples above listed all coming from the Paramo de Rosas,
