to their success in hunting them. Three skins have been re- 
ceived, which appear to belong to three different species ; 
the one of middle size being without doubt the true Canada 
goose. The smallest one differs in the form of the bill, which 
is more Bernicle-like ; it resembles B. Hutchinsii ; and Sir 
William Jardine informs me it agrees very exactly in size, &c., 
with a bird from Mexico, described by Cassin, from the Phila- 
delphia Museum, under the name ofparvipes. And he adds, — 
" Its being from Mexico is no drawback, the Philadelphia Mu- 
seum possesses only one specimen, and that would be migra- 
tory." The largest specimen seems also distinct, and does not 
appear to have been described ; and as it is obvious that, 
whether it be really a new species or merely in a different state 
of plumage, it must, when it becomes known, be sooner or later 
described and made identifiable as a variety, if not as a species, 
I think I can do no harm in describing it, and giving it a pro- 
visional cognomen. 
Bernicla leuGolcema, (Murray). (Plate I.) 
Beak black ; head and greatest part of the neck black ; chin 
and throat white, the white extending upwards and backwards 
beyond the ear coverts, and also extending downwards along 
the under side of the neck almost to the end of the black por- 
tion, but tapering away and becoming narrower and somewhat 
interspersed with black feathers as it extends downwards; the 
under eyelid broadly white ; the white on the cheeks, &c., 
without black flecks ; the black on the fore part of the head 
and behind the white space flecked with white ; the back and 
the wing coverts, the secondaries and tertials light brown, 
with lighter coloured edges to the feathers ; primaries dark 
brown ; tail feathers black ; the rump black ; upper tail 
coverts white ; lower part of the neck pale dirty lavender ; 
upper part of breast still paler ; lower part and belly almost 
white, except a broad pale lavender-coloured band across the 
middle, just before the tops of the thighs, or, perhaps, I 
should rather express it as breast and belly pale lavender- 
coloured, with a broad white band across the breast ; vent 
and under tail coverts white ; legs and first phalanges pale 
brown, probably paler when in life ; remainder of the phalanges 
and interdigital membranes bright yellow, sparingly spotted 
here and there with black or brown. Length, 40 inches. 
Its general appearance is very much the same as that of the
