CATALOGUE BIRDS. 



Interior Sounds on the west coast of Patagonia. 



Molina describes a Chilian duck, anas coscoroba, thus : A. rostro 

 extremo dilatato rotundato ; cor pore albo ; but I do not think it can 

 be the same as mine, or he would have noticed its red feet and 

 bill. It certainly is not A. candidus, of Viellot ; the ganso bianco 

 of D' Azara, which the author of the article in the Diet. d'Hist. 

 Nat. xxiii. supposes to be the one and the same with A. coscoroba. 

 Molina gives but a short description of that bird.

Smaller than M. brachypterus. 

 This bird having a smaller body than the first, is enabled to 



fly ; which with the scapulars and the feathers of the throat being 



of a redder hue than those of M. Brachypterus, authorizes its being 



considered as specifically new. 



76. Anas nigricollis.— Ind. Orn. ii. 834. 

 This bird has a wide range on the South American continent 

 It frequents the River Plata, Strait of Magalhaens, and several 

 parts of the Western Coast, as far up as Childe.
