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 re^ 



cognized 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 U3 (P. Z. S. 1869, p. 635) 



fronrMr. 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 untrust-* 



worthy.
