may be thought by some that this difference of length may be the result of age; but this cannot be maintained, as its bill is small and weak, suited to its aquatic habits—very unlike the short bill of the Bean-Goose, suited to its granivorous and herbivorous feeding."
Here then we get the crux of the whole matter. A Goose of aquatic habits would need a long swan-like neck and large swanlike feet, the two characters which are so striking in my bird! In the illustration which accompanies this paper, I publish for the first time the head and neck of Anser paludosus, side by side with that of a typical A. segetum. For their portraits to be taken the birds were placed opposite each other on exactly the same level, so that a glance will show the extraordinary disproportion in the length of neck in each bird; at the same time the difference in shape and the remarkable colouration of bill in paludosus are apparent. I feel sure that no one who may critically examine these figures will fail to be convinced that the birds are of totally distinct species. A question which may have to be discussed in the future will be, whether the bird should not be placed nearer to Anser cygnoides than A. segetum. It is almost incredible that a bird so handsome and striking in appearance as this is should have so completely escaped observation, not only here, but on the Continent as well. I can only ascribe this to the extreme rarity of the species, for it is certain that if Count Salvadori had ever seen the bird he would not have passed it over.
As no complete description of this species has ever been published, so far as I can discover, I here append one:—
As before stated, the bird is of very large size, equalling a fine Grey-lag. The general tone of colouration of plumage resembles that of the Bean-Goose, but is much bolder and decisive-looking. The head is blackish umber from sides of bill, fading into a dark drabish umber for rest of head and upper neck; at base of bill the faintest possible trace of white, curiously exaggerated by the camera in figure (p. 445); the middle and lower neck has a distinct rusty brown tinge. Mantle deep dusky brown, broadly margined with pale drab and light brown. Back and rump dark slaty brown. Upper tail-coverts white, the middle ones clouded with drab. Tail of eighteen feathers, long and broad, of a rich seal-brown, each distinctly fringed and very broadly terminated with white. Breast
