(1601) Cypsiurus balasiensis palmarum (Gray).
The Western Palm-Swift.
Tachornis batasiensis palmarum, Fauna B. I., Birds, 2nd ed. vol. iv, p. 338.
Cypsiurus batasiensis palmarum, ibid. vol. viii, p. 631.
The Western race of Palm-Swift is found over the whole of North¬-West India as far East as Chota Nagpore and Lohadaga in Western Bengal and to West Bihar. South it is found as far as Belgaum in the Bombay Presidency and the Northern Deccan.
There is nothing one can add about the nidification of this race that has not already been, said about the preceding one.
It breeds during a great part of the year. Thompson obtained eggs in the Mirzapar district in March ; Theobald in Monghyr in June and July ; Bingham at Allahabad in March, April and May and again in July and August ; while Betham found them breeding at Baroda in July.
The full clutch is two or three eggs, and I have never seen more, though Adam informed Hume that he had found five eggs in a nest.
The eggs are quite indistinguishable from those of the other races, but I have measured too few to make the measurements of any value. Some taken by Betham average 17.5 x 11.3 mm.
