Species of the Genus Pipra. 15 



Specimens from the Chamelicon River in Honduras and 

 from Chontales and La Libertad in Nicaragua are practically 

 identical with those from E. Mexico and Guatemala. All 

 have the thighs very pale yellow, the axillaries pale yellowish 

 or even yellowish white, and the pale yellow chin-spot fairly 

 extended. The inner webs of the quills always shew very 

 distinct yellowish-white margins. 



In P. mentalis and its southern forms the tail is quite 

 square as in P. rubrocapilla, and is thus very different in 

 shape from that of P. chloromeros. 



The female is very much like that of P. rubrocapilla, but 

 generally the lower parts are rather more greenish and the 

 middle of the abdomen more yellowish. The best character, 

 however, consists of the pale yellowish (not whitish) axil- 

 laries and under-wing-coverts.
