CRAG SWALLOW. 187 



blackish; iris hazel, or, according to M. Roux and M. 

 Crespon, gold-colour. 



According to Degland, the young before the first 

 moult have the feathers of the upper parts bordered 

 with russet; those of the inferior parts of a yellow 

 russet, and the throat spotted with brown on a white 

 ground. 



My figure is after a specimen kindly sent me by 

 Mr. Tristram, marked "Kedron, near the Dead Sea, 

 March, 1858." 



The bird has also been figured by Naumann, pi. 

 146; Vieillot, Faun. Ft., pi. 39; Roux, Ornith. Provence, 

 pi. 142; Bouteil, Ornith. du Dauph, pi. 38, f. 6; Gould, 

 B. of E., pi. 56.
