Genus ANAS. 

 This genus contains seventeen species, some of which are practically 

 cosmopolitan and others confined to comparatively small areas. India 

 possesses but two species, Anas boscas and A. pcecilorJiT/ncha, the 

 former of which is cosmopolitan, whereas the other belongs to our 

 local avifauna. The genus is recognized by its broad but not spatulat- 

 ed bill, which is about the length of its head ; moderate tail, of which 

 the central tail feathers are not lengthened ; 

 secondaries and dark grey wing coverts. 



Ket/ to Species, 

 Speculum purple-blue or violet ; no white on 



outer webs of inner secondaries ...
