Penelope argyrotis, OgilYie-Grant, Cat. B. Brit. Mus. xxii. p. 



501 (1893)- 



Adult. — Easily distinguished from all the other species of 

 Penelope previously described by the tail-feathers, which have a 

 distinet terminal band of rufous. In other respects it most 

 nearly resembles P. sclaferi, but the pale eyebrow-stripes are 

 more marked, and the feathers of the mantle, wing-coverts, 

 and breast are edged with pure white. Total length, 24 

 inches; wing, 10-10-9 ; tail, 10*5 ; tarsus, 2-3 ; middle toe and 

 claw, 2-y 



Eange. — South America; Ecuador, United States of Colombia, 

 and Venezuela. 



XV. THE WHITE-WINGED PENELOPE. PENELOPE ALBIPENNIS. 



Penelope albipennis, Tacz. P. Z. S. 1877, p. 746; Ogilvic- 



Grant, Cat. B. Brit. Mus. xxii. p. 502 (1893). 



Adult Male. — Appears to be most nearly allied to P.jacupeha 



and P. ortoni^ but differs from these and all other species of 



Penelope in having \hQ first eight primary quills ivhite^ with only 



the base and tip dusky, and the ninth quill whitish towards the 



middle. Wing, 13; tail, 13; tarsus, 3-4; middle toe and claw, 



37. 



I have never seen an example of this bird, but from what 



Mr. J. Stolzmann, the original discoverer of the bird, says, it 



is clearly a well-marked species, and not a partial albino, as one 



mid-it at first be inclined to believe.
