The Grey Ducks. 149 



white below it. Above the speculum, 

 however, instead of a similar double band, 

 as in the Indian Grey Duck, there is but 

 a single band, of a black colour. Instead 

 of the outer webs of the two long 

 secondaries next the speculum being 

 entirely white, these webs exhibit hardly 

 any white. The Chinese Grey Duck has 

 a wide range, extending from Japan down 

 to China. It is a resident species, but 

 its southern limits are not definitely 

 known. There is no other Grey Duck 

 likely to occur within the limits of the 

 Indian Empire.* 



* There is no genus in which the Grej' Ducks 

 can be placed, and I therefore propose the name 

 Polionetta for them, with Polionctta pcecilorhyncha 

 as the type of the genus.
