5. Chenalopex jubata (Spix) \ Orinoco Goose. 

 Anserjubatus, Spix, Av. Bras. ii. t. 108. 

 Chenalopex jubata, Gray et Mitch. Gen. B. iii. t. clxiv. 

 Hab. Lower Amazonia. 



Introduced, I believe, by Lord Derby at Knowsley, where it bred 

 freely for many years (see 'Gleanings,' vol. ii. sub tab. xv.). It 

 has not bred with us, at any rate of late years, although we have had 

 specimens ever since 1830. 



Genus Anser. 



6. Anser cinereus, Meyer. Grey-Lag Goose. 

 Anser ferus, Gould, B. Gt. Brit. v. t. i. 



Hab. Palaearctic Region. 



The Grey-Lag Goose occurs in the earliest lists (Rep. Council, 

 1831, p. 22), and is recorded as having bred in the Gardens in 

 1842 (April 21st), In 1843, as mentioned in Yarrell's 'Birds' (iii. 

 p. 34), the Grey -Lag crossed with the Domestic Goose in the Gardens. 

 Some of the produce were exhibited by Mr. Bartlett at the " Prize- 

 Poultry Show " held in the Gardens by the Society in June 1845, 

 and obtained a prize. " Cross-bred Geese," probably of the same 

 stock, were also batched in several subsequent years, as will be seen 

 by the subjoined table.
