230 LLOYD’S NATURAL HISTORY. 
Total length, 28 inches; wing, 11°8; tail, r1°1; tarsus, 3°2 ; 
middle toe and claw, 3°2. 
Range.—South America; Bahia, Brazil, and British Guiana. 
XIV. THE BAR-TAILED PENELOPE. PENELOPE ARGYROTIS. 
Pipile argyrotis, Bonap. C. R. xlii. p. 875 (1856). 
Penelope montana, Licht ; Bonap. C. R. xlii. p. 877 (1856). 
Penelope lichtensteinit, Gray, P. Z. S. 1860, p. 269. 
Penelope argyrotis, Ogilvie-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 
distinct terminal band of rufous. In other respects it most 
nearly resembles P. sclater7, but the pale eyebrow-stripes are 
more marked, and the feathers of the mantle, wing-coverts, 
and breast are edged with wre white. Total length, 24 
inches ; wing, 10—-10'9 ; tail, 10°5 ; tarsus, 2°3 ; middle toe and 
claw, 2°3. 
Range.—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; Ogilvie- 
Grant, Cat. B. Brit. Mus. xxii. p. 502 (1893). 
Adult Male—Appears to be most nearly allied to P. acupeba 
and P. ortoni, but differs from these and all other species of 
Penelope in having the first eight primary quills white, 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, 
3°76 
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 
might at first be inclined to believe.
