Moore, of the Falkland Islands, in 1857 ; and a second pair was re- 

 ceived in 1861. The first young birds were hatched in 1863; and 

 the species has since bred with us with tolerable regularity, as will 

 be seen by the following list.

We first received examples of this form of the ^lagellanic Goose 

 in 1871. The female having died, the male was lent to a corre- 

 spondent, who j)Iaced it along with a female B. magellanica. In 

 1875 this pair bred and produced hybrid birds, of whicli a pair were 

 received in exchange by the Society (see P. Z.S. 1876, p. 365, 

 where they are figured). 



We have since received several pairs of the pure bird from South 

 America.

The first examples of this Goose were received in 1833. It 

 bred frequently in the Gardens from 1852 to 1869, when we unfor- 

 tunately lost most of our stock. We have quite lately succeeded in 

 obtaining some newly imported birds, and hope now to begin breed- 

 ing them again.
