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. 244, fig. 2, from an Arabian specimen.
