 of the back black ; middle and lower back, wing-coverts, and 

 scapulars white, with numerous fine undulating black lines ; rump

The female has the crown, nape, and sides of the neck, and the 

 upper part of the back, reddish-brown ; the back as in the male, 

 but the lines less distinct ; throat and forepart of the neck white, 

 mixed with reddish ; breast reddish-brown, mottled with white ;

This Pochard appears to be more abundant in Western India than 

 in Bengal, but occurs throughout the whole country in small parties, 

 generally on the larger and more open tanks. 



It inhabits Northern Europe and Asia, and breeds among reeds 

 and plants, laying twelve or thirteen greenish-white eggs. 



The American representative is now considered distinct, A. 

 Americana, Bonap. ; and there is, besides, in North America, the 

 A. valisneria, or Canvas-back, said to be the best of all the Ducks 

 of the New Continent.
