or even Henicorhina. Its bill, however, seems to be that of a 

 typical Troglodytes, wholly lacking the notch toward the end of the 

 edge of the upper mandible. 



It is at all events a very distinct, peculiar species, needing 

 comparison with no other known wren, its large feet and long 

 tarsus, its short, slender tail, and the conspicuous white edgings 

 of the primaries, distinguishing it at once from any other Troglo- 

 dytes or from Hemiura.

 dusky — the darker bars on wing coverts very indistinct ; alula dusky, slightly 

 spotted with isabella color ; bend of wing grayish white ; lining of wing gray 

 mottled with dusky; tail chestnut, barred with blackish; throat white,
