The female figured by M. Nilsson so closely resembles 

 the females of the Eider and King Ducks, which arc de- 

 scribed, and the latter represented on the opposite page, that 

 it is only necessary to notice the difference in the wing of the 

 Western female, which has the greater coverts and the secon- 

 daries tipped with white, forming two bars enclosing between 

 them a bluish-black speculum. Our figure of the female 

 Western Duck was taken from M. Nilsson"'s coloured plate.
