Interior Sounds on the west coast of Patagonia.

Molina describes a Chilian duck, anas coscoroba, thus: A. rostro extremo dilatato rotundato; corpore 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 blanco of D'Azara, which the author of the article in the Dict. d'Hist. Nat. xxiii. supposes to be the one and the same with A. coscoroba. Molina gives but a short description of that bird.

Capite colloque canis; dorso superiori corporeque inferiori albis, nigro confertim fasciatis; dorso imo remigibus, rectricibusque nigris; ptilis speculoque albis; tarsis subelongatis.
