Two examples of this singular bird, one from the Upper, the other 

 from the Lower Ucayali. The most nearly allied species is Sclater's 

 Euscarthmus agilis, afterwards transferred by him into the genus 

 Anceretes. But the present bird must certainly be generically sepa- 

 rated from Anceretes ; and perhaps the species last referred to ought 

 likewise to stand alone as a link between the two genera. 



The characters of the genus Stigmatura, as we propose to call this 

 form, consist ( 1 ) in the very short wings, the longest primaries (third 

 and fourth) hardly exceeding the longest secondaries ; (2) in the 

 very long tail, formed by graduated feathers (much as in Anceretes 

 agilis) ; and (3) in the long strong tarsi and short hind claw. Ance- 

 retes agilis has similar tarsi, but the hind claw is much stronger and 

 longer. Stigmatura is further remarkable for the black and white 

 banded tail, which is unlike anything in the whole group of Tyran- 

 nidce ; it is very different in style of coloration to Anceretes, and in 

 this respect comes nearer to Hapalocercus.
