278 GAME-BIRDS OF INDIA 



Genus PTEROCLURUS. 



The genus Pteroclurus is, as I have already said, scarcely worthy 

 of division from Pterochs, the only difference being that the central 

 tail-feathers of the former genus are produced in long filaments 

 beyond the other rectrices, whilst those of the latter are normal. 



There are altogether four species in this genus, which have further 

 been divided into subspecies. Three species are found in India, of 

 which one, sencgalensis crlaangeri, is a permanent resident, one, 

 alchata, is, practically if not wholly migratory, and the third, 

 senegallus, very rarely breeds within Indian limits.
