BIRDS OF BRITISH BURMAH 
America, and appears to be the same familiar bird in that continent that 
H. rustica is in the Old World. It seems to occur often in Eastern Asia. 
Mr. Dresser mentions having seen a specimen from Lake Baikal, and 
I have examined one shot by Mr. Swinhoe in Formosa. 
288. HIEUNDO TYTLEHL 
TYTLER^S SWALLOW. 
Hirundo tytleri, Jerd. B. Ind. App. iii. p. 870; Hume, S. F. iii. p. 41 ; Wald. in 
Bl. B. Burm, p. 127; Wardlaiu Ramsay, Ibis, 1877, p. 466 j Hume 8f Dav. S. I. 
vi. p. 41 ; Hume, S. F. viii. p. 84 ; Simson, Ibis, 1882, p. 84. 
Description. — Male and female. Like H. rustica, but with the underparts 
very dark ferruginous, nearly as dark as the throat. The collar across the 
fore neck is very narrow and indistinct. 
Dimensions about the same as those of H. rustica. 
This species runs very close to H. cahirica of Egypt in the colour of 
the underparts, but the latter has a very distinct broad collar like 
H. rustica. 
Tytler^s Swallow visits British Burmah in considerable numbers every 
winter, but is much more common in some years than in others. Capt. 
Wardlaw Ramsay remarks that it is common in the plains of Karennee. 
Dr. Tiraud states that it is not rare in Cochin China. Mr. Simson, who 
first drew Dr. Jerdon^s attention to this species, writes that it visits 
Dacca in an erratic manner, sometimes abundantly, sometimes in small 
numbers. Col. Godwin- Austen observed it in the Khasia hills, and it 
has been procured also at Darjeeling. A specimen collected by Dr. Jerdon 
in the Khasia hills, and now in the British Museum, is referable to this 
species. 
This Swallow is probably a Central- Asian species, breeding there, and 
visiting Southern Asia in winter. Its habits are precisely the same as 
those of H. rustica, and the two birds are generally seen together ; but the 
deep rufous colouring of the underparts of H. tytleri serves at once to 
distinguish it.
