Species of the Genus Pipra. 37 



Count Berlepsch's collection proves beyond doubt that young 

 males have the crown duller and of a less shining blue than 

 the adults. Consequently, the specimens from Chyavetas 

 and Rio Huallaga cannot be young males of P. coronata, as 

 considered by Sclater and Salvin. 



The following references pertain to this doubtful form : — 



Pipra cyaneocapilla (nee Halm !) Scl. & Salvin, P. Z. S. 



1866, p. 190 [Upper Ucayali] ; iid. I.e. 1867, p. 751 



[Chyavetas] ; Iheriug, Revist. Mus. Paul. vi. (1905) p. 435 



[Rio Jurua, W. Brazil]. 



The measurements of the three specimens examined by me 



are as follows : —
