 circling round the Moorish towers of Spain. Its 

 return southward in autumn is apparently by the 

 same route as that chosen for its northward 

 journey in spring, and in this respect it differs in 

 habit from many other species.^ 



In India its place is to a certain extent taken 

 by a non-migratory species, Cypselus affinis, but 

 it has nevertheless been met with in that country. 

 An Indian specimen was received from Dr. 

 Jerdon, presumably from the north-west.^ It 

 has also been forwarded from Afghanistan,* and
