Syrnium bartelsi Finsch, Bull. B. O. C. xvi. p. 63 (1906). 



Adult female. Upper parts uniform dark chocolate-brown, 

 crown somewhat darker ; longest upper tail-coverts with equi- 

 distant cross-bars of lighter brown ; wing-coverts dark brown 

 (like the back), the greater coverts with indistinct lighter 

 cross-bars, which become more marked on the coverts of the 

 secondaries ; spurious wing uniform dark brown ; coverts of 

 the primaries distinctly cross-barred with light brown (the 

 light bars as wide as the dark) ; the first primary uniform

 remaining primaries and still more so on the secondaries ; the 

 longest primary (which is the 5th) crossed with about seven- 

 teen dark and as many light equidistant cross-bars ; longest 

 shoulder-feathers rufous on the inner web, white on the outer,
