parties; but^ as a rule, I found it rare in Kashmir, notwith- 

 standing its name. Is Chelidon lagopoda (Pallas), Swinhoc, B. 

 of China, no. 129, distinct from this bird ? 



95. ACANTHYLTS SYLVATICA. 



Mr. Hume has received specimens of this Swift from Coonoor, 

 Neilgherries, and Gurhwal. 



97. ACANTHYLIS CAUDACUTA. 



This is the Sillianff-tiphi-timbo of the Lepchas of Darjeeling. 

 Dr. Tristram appears to doubt the possibility of this Swift (or any 

 other bird) exceeding Cypselus meJba in rapidity of flight. Mr. 

 Blanford, however, fully confirms my views *, and indeed in- 

 tensifies them considerably ; and Major Godwin-Austen also, 

 in his recent catalogue, states that he saw a large Swift which 

 he presumed to have been Acanth. caudacuta flying with great 

 velocity : " they shot past like lightning." 



98. Cypselus melba. 



Since the publication of ' The Birds of India ' I have seen this 

 species occasionally at Darjeeling. 



99. Cypselus apus. 



Going up the valley of the Sutlej from Simla I first met with 

 this bird at Serahan, and thence occasionally all the way to 

 Pangi ; but it was in the Lipi and Asrang valleys that I found 

 it most abundant. One I killed near Lipi was sent home to Mr. 

 Blythj who recorded it, and gave the specimen over to Mr. Gould. 

 He had previously only seen it from Afghanistan. This last 

 naturalist considers it distinct from the European bird, it being 

 of somewhat larger dimensions, the wing especially being longer. 

 One I measured when fresh was 7 inches long, wing 7^, ex- 

 panse 16|, tail 3^, forked for 1^ inch. 



101. Cypselus leuconyx. 



Stoliczka remarks that in some specimens of this species there 

 was no trace of white on the claws. This character indeed is ex- 

 ceptional, and the name is therefore unfortunate. Dr. S. also 

 states that a shght pale supercilium is generally traceable, and that 

 the head and neck are paler than the back. The wing measures
