coverts, grey-brown with a vinaceous tinge; longer upper tail-coverts, 
whitish ; wings, deep grey; tail, dark grey, tipped with whitish. 
Breast and abdomen, greyish brown, paler on. the breast; under tail- 
coverts, brownish white. 
Iris, dark brown (Oates), Bill, plumbeous blue, except tip, 
which is blackish. Legs, slate-colour ( Oates ). 
Habits, ete. This is probably a resident species, though I have 
only obtained specimens in July and August. Its flight is strong and 
eraceful, and it spends a considerable part of its time in the air, 
hawking for insects, but when at rest it usually takes up its position on 
an exposed branch of a tree. While on the wing, it has a swallow- 
like appearance; hence its English and Siamese names—the latter 
meaning “ Jungle-Swallow ”. 
Distribution. The only previous record I can find of its 
occurrence in this country is Oates’ statement that it ‘‘ extends into 
Siam.”
