The White-clawed Swift, Jerdon.

Coloration similar to that of C. pacificus, but dimensions much less, so as fully to justify separation. The feet (not the claws) are pale coloured, almost albescent in some specimens (Hume).

Bill blackish; iris dark brown; feet flesh-colour (Delme Radcliffe).

Length about 6 inches; tail 2.5 ; wing 6 ; tarsus -4 ; the outer exceed the middle rectrices by about .75 inch.

Distribution. Common in the North-western Himalayas at moderate elevations " between the outer ranges and the higher and more interior hills " (Jerdon); probably resident. Jerdon states that he obtained a specimen in the western part of the Deccan and several in Malabar, where it frequents rocky hills, but no one appears to have observed specimens in the Peninsula since Jerdon wrote.
