Cypsellus leuconyx, Blyth.
101. :- Jerdon's Birds of India, Vol. I, p. 179 ; Butler, Deccan and South Mahratta Country; Stray Feathers, Vol. IX, p. 379.
THE WHITE-CLAWED SWIFT.
Length, 6.25 ; tail, 2.5 ; wing, 6.75. Feet small; claws white, or more or less so. Very similar in color to the last; above glossy blackish-brown, darkest on the head; the rump white ; beneath the chin and throat dirty white ; the rest of the body glossy brown ; the tips of the feathers whitish ; the tail is forked, the outer feathers being about one inch shorter than the central ones.
In the Ibis for 1871-72, Dr. Jerdon considerably modified the above description. I cannot do better than reproduce the passage: :- " Stolickza remarks that in some specimens there was no trace of white on the claws. This character is indeed exceptional, and the name is therefore unfortunate." Dr. S. also states that a slight pale supercilium is generally traceable, and that the head and neck are paler than the back.
Dr. Jerdon obtained a specimen in the western part of the Deccan, and several in Malabar ; it does not appear to have been procured by any other naturalist.
