468 PATAGONIAN EXPEDITIONS: ZOOLOGY. 



Argentine Republic and even more so in Brazil, while it does not 

 appear in Durnford's List. Mr. Hatcher and his assistants did not pro- 

 cure representatives of the species. The five birds in the University col- 

 lections are all from the Province of Buenos Aires in Argentina ; four 

 were taken at La Plata in May and the fifth at Chascomus in November , 

 the bird is therefore apparently resident in this region. 



There are eggs of this duck in the collections of the British Museum, 

 taken in Argentina, in November and also others undated taken in Chili. 

 The birds have bred in the Zoological Gardens in London, where they 

 have been represented for many seasons.
