uniform oil-greeu above and below, while the male is steel- 

 blue with a large amount of white edgings to the feathers 

 on the breast, upper wing-coverts^ and scapulars. 



The black shaft-lines to the feathers of the otherwise 

 white crest are very conspicuous in the Bolivian bird 2921, 

 an adult from Peru (Gray's type of P. jacquinii), and the 

 bird from Paraguay. The remainder ol: the series have an 

 almost uniform cream-white crest. 



I have measured the wings and tails of the entire series, 

 and find that the southern birds have a slightly larger 

 average measurement in both male and female.

I have compared these examples with a series of nine 

 other specimens in the National Collection from Colombia, 

 Merida in western Venezuela, Ecuador, and Peru. In this 

 series I notice that Colombian and Venezuelan birds show 

 a good deal of oil-green colour in the plumage, while those 

 from Ecuador and Peru have an inclination to steel-blue. 

 This character may denote sexual difference however, as in 

 the case of Pipile cumanensis, but the number of sexed 

 specimens in this series are not sufficient to prove it. The 

 measurements of the wings and tails of this series do not 

 show any great variation.
