feathers of the neck and mantle are more conspicuously edged (later- 

 ally) with white, and the middle rectrices are decidedly more coppery, 

 while all are broadly tipped with chestnut, instead of narrowly tipped 

 with buffy rufous, as in argyrotis. The abdomen and tibiae are also 

 decidedly more rufescent than in the latter form. 



Bonaparte's original description of Pipile argyrotis (Comptes 

 Rendus de V Academie des Sciences, XLII, 1856, 875) is very brief and 

 unsatisfactory, but the species was later identified by Messrs. Sclater 

 and Salvin {Proceedings Zoological Society of London, 1870, 528) from 

 an examination of some of his authentic specimens. Meanwhile it 

 had been given two other names. Penelope montana Reichenow 

 (Tauben, 1862, 151, ex Lichtenstein, MS.), and Penelope lichtensteinii 

 Gray (Proceedings Zoological Society of London, i860, 269), both based 

 upon material from Venezuela. 



For comparison I have had five skins of P. argyrotis from Las 

 Quiguas and La Cumbre de Valencia, Venezuela. As yet I have 

 seen no specimens of P. colombiana except from the Santa Marta 

 district of Colombia, but its range may possibly be much more ex- 

 tensive.
