Riparia chinensis chinensis, Riley, U. S. Nat. Mus. Bull. 172, 1938, p. 264 (Hang 

 Turn Kai, Mae Hiak [localities on the Salwin] ). 



This diminutive swallow is, at least locally, very common on the 

 Salwin, the Mae Kok (Chiang Kai), and the Mae Khong but has 

 never been found elsewhere in our provinces (although it occurs in 

 small numbers on the Mae Ping below the Gorges) . 



Gyldenstolpe has noted (1916) that the flocks rest on the sand bars, 

 often crowding the branches of the scattered bushes growing in such 

 places. 



Specimens taken by Smith, January 15, 1933, on the bank of the 

 Salwin, were captured at night in holes, which may indicate that 

 breeding was in progress at that time. 



This species has the upperparts gray-brown, distinctly paler on 

 the rump and upper tail coverts; the entire throat and breast pale 

 gray-brown, changing to white on the remaining underparts.

 area, from the plains to about 5,500 feet.
