2. Additional Note on the Upland Goose (Chloephaga 

 magellanica). By Philip Lutley Sclater. 



In my note upon this bird in last year's 'Proceedings' (p. 128), I 

 spoke somewhat doubtfully as to the brown bird figured by Button 

 (PI. Enl. 1006), and upon which Gmelin's term magel/anicus was 

 founded, being really the female of the white bird. The legs of the 

 brown bird are yellow, and of the white bird black, a variation almost, 

 I believe, wit liout precedent in sexes of the same species. I had hoped 

 that the epiestion would have been settled by the pairing and breed- 

 ing of these birds this spring ; but this has not yet taken place, al- 

 though the Chloephaga poliocephala has bred freely for several rears. 

 But the subjoined letter, which I have received in answer to an ap- 

 plication for information made to Mr. James Hunt, the intelligent 

 Ibad Keeper of the Gardens, seems to set this epiestion of their 

 being sexes of the same species quite at rest. 



Zoological Gardens, Regent's Park, 

 _, April 27th, 1858. 



OIR, 



I beg leave to inform you that the person who reared the four 

 Magellanic Geese presented to the Society by His Excellency Go- 

 vernor Moore, when in the Garden on the 5th of April last, stated 

 that these birds were hatched about Get. 1856, from eggs taken 

 from tlie nest of the wild bird by Corporal Brown. 



The eggs were set under a common hen, and four young ones 

 were batched from them, one of which died cpiite young ; the other 

 three are the three at present living in these Gardens. The fourth 

 one that arrived with these three had one of its wings injured when 

 it arrived here. This was a wild bird, taken when quite young ; and 

 the wing was injured in it> capture. 



lie also Mated that the black ami white bird with the black 



is the male, and the two that are with it with the yellow tegl are 

 the females ; that they are all hatched with black legs, and remain 

 with the legs of that colour for some WCekl after they arc hatched ;
