case referred to was as follows. — “ A female hybrid Polish swan (bred 
between this species and the mute swan) paired with a mute swan at 
the garden, Phoenix Park, and during two seasons had eggs, on which 
she sat, but no young were produced. She may have been robbed of 
the eggs before the proper time for incubation, as the nest was found 
empty;” — it is not stated whether in one or both seasons. 
Two adult hybrids between the mute and Polish swan, of which the 
bird just noticed was one, came under my observation in March 1847, 
in the garden already mentioned. The bill and fleshy excrescence at 
its upper base were perfectly similar in colour to the same parts in the 
mute swan, from which the birds, on the whole, differed only in being- 
smaller, and having the legs and feet of a dirty greenish flesh-colour, 
instead of black. * 
Canada Goose ( A . Canadensis ), male, and Common Tame Goose (A. 
ferns'). Islay House (island of Islay), Scotland, January 20, 1849. — 
A male of the former, bred with a tame goose here, and I saw the 
well-marked progeny nearly as large as the male parent, with similar 
markings, but in much fainter and less decided colours ; the mark on 
the cheek, instead of white, being “ whitey-brown,” See. 
Canada Goose and Bernacle {A. bernicla). Islay House , January 20, 
1849. — I saw a couple of very handsome and peculiar-looking birds 
here to day, which were sent from the collection at Knowsley, the 
Earl of Derby’s ; and were said to have been produced between these 
species. Their parentage being partially from the Canada goose, was 
at once evident, as they had its cheek mark, but of a cc whitey-brown ” 
hue : — they were pure white round the base of the bill. Plumage of 
the body generally resembled that of the Canada goose. Their legs 
were reddish-yellow, and one bird had them much lighter in colour 
than the other. The bills were very small and bernacle dike. 
Sandwich Island Goose ( Bernicla Sandvicensis, Vigors), male, and- 
Tame Goose. Islay House , January 20, 1849. — Sandwich Island 
geese, of which I saw a pair, were brought here some years ago. The 
gander deserted his proper partner and “ took up ” with a common 
tame goose, in the neighbouring village of Bridgend. Two young 
were produced the first year and seven the second. The goose was 
unfortunately killed before the third year. The place chosen for the 
nest was on the ground, in the churchyard, beneath the shelter of a 
grave-stone which inclined much from the perpendicular. Here the
