Species of the Genus Pipra. 19 



brown ; iris yellowish white (J. Kalinowski, MS.). Wing 61; 

 tail 27 ; bill 8£ mm. 



? ad. — Agreeing with that of P. mentalis ignifera and 

 P. m. minor in having the under-parts strongly washed with 

 dull olive-greenish, except the pale yellowish middle of the 

 abdomen, but easily known by its distinctly rounded (not 

 square) tail. Wing 61-64 ; tail 27-30; bill 8-9 mm. 



There is no appreciable difference between the males from 

 different parts of Peru, either in size or colour. Some 

 specimens shew a few pale red feathers on the thighs, but 

 the latter are always pale yellow, never red and white as in 

 P. rubrocapilla. The axillaries and under-wing-coverts are 

 usually uniform black, margined only in immature birds 

 with greyish or whitish.

The adult male of P. chloromeros differs from that of 

 P. rubrocapilla, besides having yellow thighs, in its deep 

 black axillaries and under-wing-coverts, in lacking the 

 whitish edges to the inner webs of the secondaries, and in 

 the form of the tail. The latter is distinctly rounded, the 

 outermost tail-feather being the shortest and about 5-6 mm. 

 less than the longest. The shafts of the outer rectrices are 

 stiff and rather thickened at the base, a peculiarity already 

 noticed by Taczanowski l . In P. rubrocapilla and P. mentalis 

 the tail is quite square, and the shafts of the outer rectrices 

 are soft and thin. 



The female is also easily known by its distinctly rounded 

 tail (the outermost rectrix about 5 mm. shorter than the 

 longest) ; while it is quite square in P. mentalis, P. rubro- 

 capilla, and P. erythrocephala.
