Land, and is the only species of Swallow which remains 

 throughout the year, a few couples being always to be 

 found in suitable localities. I once saw a very large 

 number at Hykomkap on the 20th of May. 



This species breeds in the holes of low rocks and clay- 

 banks. The nest is cup-shaped, and built of the usual 

 clay materials ; the eggs are five or six in number, white, 

 tinged with fawn, and spotted with brown. 



The iris in this species is of a very dark brown ; the 

 bill is brown, the upper mandible being darker than the 

 lower ; the legs and toes are brown.

 imagine that it must be partially migratory, as during
