the same, is lighter, and the throat is whitish, mottled 
with dusky spots. Under wing coverts and part of the 
inner webs of wing feathers below, rich silky dark 
fawn; ends of primaries brown. There is the usual 
tendency to form a crest of the head feathers. Beak 
yellowish horn-colour; feet, legs, and iris, clear brown. 
The young before the first moult, according to 
Degland, have the colours brighter, with the feathers 
of the upper parts of the wings and tail bordered with 
grey. 
My figure of this bird is from a female specimen shot 
by Mr. Tristram, in the Northern Sahara, December 
2nd., 1856. The egg is also from a specimen taken by 
the same gentleman in that locality. 
The bird has been figured by Temminck and Laugier, 
pi. color. 24T, fig. 2, from an Arabian specimen.
