ing from S. Brazil on one coast and the highlands of Peru on the 

 western side down to the Magellan Straits and the Falklands. 



Azara, its original discoverer, gives no particulars respectin"' its 

 history, merely saying that he obtained four similar specimeifs in 

 ^uenos Ayres. It was procured in the adjoining State of Monte 

 Video by feellow, and in the Brazilian province of Sao Paulo by 

 batterer Burmeister says this Duck is not unfrequently found in the 

 lagoons bordering the Parana. In his ' La Plata-Reise' he distin- 

 guishes a western race from the vicinity of Mendoza, for which he 

 adopts Meyens term oxyura. But after comparing eastern and 

 western specimens together, we are of opinion that they beloncr to 

 one species. j a ^ 



In Chili Philippi and Landbeck say that this is the commonest 

 species of Duck. In the Falkland Islands it occurs rather sparingly 

 m the freshwater ponds of the interior, where it resides throughout 

 the year. I he species is also found on the adjoining coast of Pata- 

 gonia; and the specimen in Dr. Cunningham's collection left unde- 

 termined m our first list of his birds ('Ibis.' 1H68, p. Ib9) certainly 

 belongs to it, though not in full plumage. Mr. Whitely has sent 

 several skms of this Duck home from the Cuzcan Andes, obtained 

 on the lake ot 1 ungasuca and on the river near Tinta,
