1S76.] NEOTROPICAL ANATIDiE. 399 



Judging from the description of Prince Maximilian, his Anas 

 erythrophthalma (Beitr. iv. p. 529), as already suggested by Salvia 

 (Ibis, 18/4, p. 319), would appear to be very closely allied to the 

 present species, if not identical with it. The male, as described, 

 seems to be in immature plumage. T]\e female agrees tolerably 

 well with that of the present bird. Prince Maximilian obtained his 

 two specimens of A. erythrophthalma in a small lake near Villa de 

 Belmonte, in S.E. Brazil, in the month of November. No subse- 

 quent travellers seem to have recognized the species so far north. 



The B.osy-billed Duck has Ijeen successfully introduced into 

 Europe, and has bred on more than one occasion in our Gardens. 

 In the 'Proceedings' for 1870 (/. s. c.) Sclater has given an account 

 of it, and figures of both sexes from the living birds.

 Fuligula, as here considered, is a purely northern form, of which 

 five species occur in winter within the Neotropical Region.

* Fleming puts Alias ferina first on the list ; but A. nyroca should be con- 

 sidered his type, if that bird is separated from Fuliyula.
