the biggest goose known. It may possibly, however, be the 
B. Hutchinsi, which is said to be distinguishable from the true 
B. canadensis by the possession of stvteen instead of eighteen 
tail-feathers. But the American geese of this form have not 
as yet been clearly differentiated, and it seems impossible to 
furnish a true diagnosis of the supposed species which have 
received the name of B. leucopareia and B. leucolema. 
* Snow Goose (Chen hyperboreus).—A few young birds only have 
been seen, and these more frequently in the Northern Inspectorate 
than in the Southern. Is found also on the west coast of Davis 
Strait. Probably breeds in the far north, but a doubt may perhaps 
be entertained whether the examples killed in Greenland belong to 
the true C. hyperboreus or to C. albatus (if these be really distinct), 
which is said to have occurred in Ireland. 
tAmerican Whitefronled Goose (Anser Gambeli). ‘ Nerdler- 
nak.”—Not rare in fresh water between lat. 66° and 68° 30’, and also 
observed by the German Expedition on the East Coast. Though 
the whitefronted goose of Greenland has been generally assigned 
to the European form, A. albifrons, it would seem to belong rather 
to the larger American A. Gambeli; but the difference between the 
two appears to be that of size only. The true A. albifrons is a 
regular visitant to Iceland, and therefore the specimen obtained by 
Dr. Copeland on the East Coast may well belong to that form, 
though it does not follow that the birds which frequent the West 
Coast are of the same form. 
Wild Swan (Cygnus ferus?) “ Kuksuk.”—The swan which 
occurs occasionally in Greenland has been generally referred 
to the European species (C. ferws), but that which was observed 
at Igloolik, on Parry’s Second Voyage, and is said to breed on 
the Parry Islands (though not numerously), seems more likely 
to be one of the American species, C. buccinator or C. ame- 
ricanus. Hence a reasonable doubt may exist as to which of 
the three the Greenland examples are. 
From the foregoing list it will be seen that, while siaty-two of 
the birds therein enumerated are nothing but stragglers to Green- 
land, the number of those which may be called denizens of the 
country cannot be raised above sivty-three, to reach which we must 
even, in some cases, stretch a point. That Greenland, so far as its 
birds are concerned, bel 2ngs to the Nearctic Region has long been
