EUNETTA FALCATA. 143 



Genus EUNETTA. 



The genus Eunetta may be at once distinguished from Anas by the 

 sickle-shaped inner secondaries in the male, and by the remarkable length 

 of both upper and lower tail-coverts, which extend beyond the rectrices. 



From Chaulelasmus, Eunetta may also be distinguished by the number of 

 rectrices, which is 16 in the former and only 1-4 in the latter. The females, 

 however, of C. streperus and E. falcata are so much alike that their 

 differences are given in full below. There is only one species in this genus, 

 E. falcata, which occurs throughout Eastern Asia.
