 P. Z. S. 1870, p. 528 [Int. U.S. Colombia, Bogota]. 



Adult. Diifers from all other species of Penelope in having the 

 tail-feathers tipped with rufous ; it differs chiefly from P. sclateri, 

 to which it is otherwise most nearly allied, in having the pale 

 superciliary stripes, as well as those from the angle of the gape to 

 the ear-coverts, whiter and more strongly defined ; the edgings of 

 the feathers on the chest and breast, as well as those on the mantle 

 and wing-coverts, pure white. Total length 24 inches, wing 10 to 

 10-9, tail 10-5, tardus 2-3, middle toe and claw 2-3. 



Two examples from San Lucas, in Ecuador, differ somewhat from 

 the typical Venezuelan example in having the chin and upper part 

 of the throat feathered, the feathers of the belly and underparts 

 rather distinctly mottled with blackish, while the feathers of the 

 mantle and wing-coverts are almost devoid of white margins ; these 

 birds are probably younger specimens.

15. Penelope albipennis. 



Penelope albipennis, Tacz. P. Z. S. 1877, p. 746 [N.W. Peru]. 



Adult male. Appears to be nearly allied to P. jacupeba and 

 P. ortoni, but is distinguished from these and all other .species of 

 Penelope by having the first eight primaries white with the base 

 and tfp dusky, and the ninth whitish towards the middle. Wing 

 13 inches, tail 13, tarsus 3-4, middle toe and claw 3-7. 



A single specimen of this species was procured by M. J. Stolz- 

 mann near Tumbez, and he states that all the other specimens 

 observed on the wing in this locality had similar white primaries. It 

 would thus appear that this bird is not merely a semi-albino form of 

 P. ortoni or some other allied species, as one might naturally be 

 inclined to believe. 



Hab. Vicinity of Tumbez, Western Peru.

Sexes different. 



Tail composed of 12 feathers, rather long and rounded ; the outer 

 pair being about two thirds of the length of the middle pair. 



1st primary much the shortest ; 8th about equal in length to the 

 10th ; SJih slightly the longest.
