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. A N S E R CINEREUS, Meyer. Grey-Lag Goose. Anser ferus, Gould, B. Gt. Brit. v. t. i. Hab. Palsearctic 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 hatched in several subsequent years, as will be seen by the subjoined table.
