This Duck is very remarkable for its conspicuous white patch on 

 each side of the face and pure white throat and neck, as well as the 

 large richlj coloured alar speculum. So far as we yet know it is 

 exclusively a western species. According to Philippi and Landbeck 

 t IS common from the Straits of Magellan as far Aorth as Valdivia 

 but is rare in the central provinces of Chili.

This species has a wider range than the last, extending northwards 

 into Southern Peru, where Mr. Whitely obtained specimens in 1867

 of 14 UOO fee . In Chili, Philippi and Landbeck tell us, it inhabits 

 the high Cordilleras in summer, but descends during winter to the 

 plains, and IS found along the coast down to the Magellan Straits 

 where Dr. Cunningham obtained specimens. 



The Crested Duck is common everywhere on the Falkland islands 

 mostly frequenting salt water, though occasionally seen near fresh' 

 water pools Old birds are always found in pairs. They live upon 

 shellfish. They retire inland to breed ; and the duck lays five e^gs 

 m a nest covere^d with down. The eggs are laid from the begindng 

 ot October to the beginning of November. 



The only near ally of this Duck in the Neotropical region is the 

 preceding species, from which it may be at once distinguished by the
