222 LLOYD'S NATURAL HISTORY. 
claw, 2°3. As already noted, this species is peculiar in having 
the chin and throat more or less covered with feathers, in which 
respect it is approached by some examples of the nearly allied 
P. sclateri and P. argyrotis. 
Range.—South America; Venezuela, United States of Colom- 
bia, and Ecuador. 
III. SCLATER’S PENELOPE. PENELOPE SCLATER?. 
Penelope sclaterz, G. R. Gray, P. Z. 5. 1860,. p. 270 ; Ogilvie: 
Grant, Cat. B. Brit. Mus. xxii. p. 493 (1893). 
Adult.— Differs chiefly from P. szonfagnit in having the 
feathers of the chest and breast margined with whitish oz the 
sides only; the eyebrow-stripes and feathers on the- cheeks 
whiter and more marked; and the rump browner. In most ex- 
amples the chin and upper part of the throat are almost naked, 
but in some these parts are partially feathered. Total length, 
22 inches ; wing, 9°5-10°2* ; tail, 9°4; tarsus, 2°4; middle toe 
and claw, 2°3. 
Range.—South America; Peru and Bolivia. 
Habits—Dr. J. Stolazmann found this species particularly 
common in Northern Peru and to the west of the Marafon. It 
is rarely met with above 7,500 feet, but at Tamiapampa it was 
very common at 9,000, and appeared to be found right up to 
the limits of forest growth. It is more noisy than the Adurria 
(Aburria aburri), and, when flying, gives vent to a sound like 
“Klou-klou-klou,” much like that made by Turkeys, and it is pro- 
bably from this cause that it derives it local name of “ Calaluja ” 
in the provinces of Chota and Jaen. In the department of 
Cajamarca it is said to nest at the same time as the Adurria, 
that is in the months of December and January. Asa rule it 
is not a very shy bird, and easily obtained. 
* No examples in which the sex has been ascertained have been ex- 
amined. Possibly the smaller birds, with a wing measuring 9°5 inches, 
are females.
