THE ALPINE SWIFT. 1 99 



Dr. Stoliczka found it at Leh, in Western Thibet. 

 I am aware that some naturaHsts have expressed 

 doubts as to the identity of the Swift found at 

 the Cape of Good Hope with Cypselus apus ; 

 but, after an examination of several examples 

 of the African bird, I have been unable to dis- 

 cover that it differs in any material respect from 

 our well-known summer migrant.

THE ALPINE SWIFT. 



{Cypselus alpinus}j 



O rare a visitant to this country is the Al- 

 pine Swift that not more than a score ot 

 individuals have been met with since the first 

 specimen was captured in 1820. In that year a 

 bird of this species was killed at Kingsgate, in 

 the Isle of Thanet, during the month of June 

 and since that time the following examples are 

 recorded to have been met with : —
