Hab. Paraguay (Azara) ; Buenos Ayres (Hudson). This fine Duck, for our first knowledge of which we are indebted to Azara, is rather scarce in collections, and has yet only been recognized in few localities. Azara obtained examples of both the somewhat dissimilar sexes in Paraguay, and described them under different names, as was first pointed out by us (P. Z. S. 1869, p. 635) from Mr. Hudson's specimens collected near Buenos Ayres. Philippi and Landbeck (Cat. Av. Chil. p. 94) deny the occurrence of this Duck in Chili, which Sclater had given on the authority of certain specimens in the French national collection marked " Chili, Gay." But we now know full well that Gay's localities are utterly untrustworthy. 10. QUERQUEDULA BRASILIENSIS. Anas brasiliensis, Briss. Orn. iv. p. 360, unde A. brasiliensis, G m . S.
