BIRDS OF EGYPT. 121 



the only Swallow, there replacing H. Biocourii ; for on our 

 return journey in 1870 we did not meet with a single specimen 

 of the latter bird south of Girgeh, where in the beginning 

 of May these two species were equally abundant. 



Forehead and throat deep rufous-brown, remainder of the 

 upper parts steel-blue ; quills almost black ; tail black, with 

 large white spots on the inner web of all but the two centre 

 feathers ; a steel-blue collar at the base of the throat ; re- 

 mainder of the underparts cream-colour ; beak black ; legs 

 and irides dark brown. 



Entire length 8 inches; culmen 0"3; wing, carpus to 

 tip, 5 ; tarsus 0"4.

80. HiRUNDO RiocouRii, Audouin. Oriental Chimney- 

 Swallow. 



This species is resident in Egypt, and very abundant. It 

 differs from the last species in not being migratory, and it 

 keeps more exclusively to the neighbourhood of houses, 

 usually selecting the inside of some native mud-hut for its 

 nest, which it begins to construct in February. 



Upper plumage and collar round the throat steel-blue ; 

 forehead and throat chocolate-brown ; under surface of the 

 body ferruginous brown ; all the tail-feathers, except the two 

 centre ones, having a large rufous-white spot on their 

 inner web. 



Entire length 7 inches ; culmen 0'3 ; wing, carpus to tip, 

 4-8 ; tarsus 0*45.
