wing a protuberance, which may have had a spur on it at some time. The bill is long, slender, and straight along the culmen, orange-yellow in colour from base to nail; along the culmen, commencing about half an inch from base, there is a remarkable shield-shaped patch of black, wich will be best understood by referring to the figure. The nail is slaty black in colour, and larger in proportion than that of A. segetum. The under mandible is black from the base for three parts of its length, then a band of orange-yellow, and terminated with a black tip. There is a very important feature in connection with the bill. The serrations on the upper mandible are large and distinct, but do not show to advantage in the photograph. On the lower mandible the serrations are remarkable and quite distinct from those of A. segetum; they are large in size, sharply pointed, and directed backward, whereas in the Bean-Geese they are straighter, blunt, and more fused together. This suggests that the bill is adapted to pulling up roots of aquatic vegetation, and is a further valuable proof of the aquatic habits alleged by Strickland. The feet are very large, with the inside nails curiously curved inwards like those of a Swan; the first nail on foot white in colour, second and third half black and white. The legs, toes, and webs are orange-yellow in colour. Iride dark hazel. Weight, 8 lb.; total length, 35 in.; wing, 19 in.; tarsus, 3·55 in.; centre toe, 3·35 in.; bill, 2·60 in.
This bird appears to have been banished from Great Britain for something like a century! it must have found a home somewhere else—but where?
It has been suggested to me that A. paludosus may be identical with Brehm's A. arvensis. A paper on this latter bird has quite recently (Oct. 4th, 1902) been communicated to the 'Field' by Mr. Frohawk, who endeavours to prove that this is the common Bean-Goose of our land. I cannot at present agree with him on several points he raises.
At first I was somewhat inclined to think that. A. paludosus might be identical with A. arvensis, as there is certainly some similarity between the bill of my bird and of that figured by Mr. Frohawk, but more mature study has for the present dispelled the idea. There is a similarity, and that is all. There are differences which would need much explanation. Mr. Frohawk appears to have examined a considerable number of Conti-
