234 Mr. W. R. Ogilvie-Grant on American Gallinae. 
Canachites canadensis canace (Norton) op. cit. p. 152 
[Canada, Northern United Spates, and New Brunswick]. 
I. Mr. Bangs attempts to shew that the Canadian Grouse 
from Labrador differ constantly from birds obtained in Maine, 
and names the former C. c. labradorius. He states that the 
upper parts in the females of the former are much less 
suffused with buff or ochraceous throughout the plumage, 
and are more nearly grey and black. 
He compares females killed between the 12th of July and 
the 9th of August^ i. e. still in entire or partial worn breeding- 
plumage, with nearly freshly-moulted females from Maine 
shot between the 16th and 27th of August. 
Our specimens shew that there is no difference in plumage 
which is not due to season or age. A female from Nipissing 
Dist., Ontario (September), and a female from Quebec 
(October), agree exactly with a female from TJngava (De- 
cember) ; all three have the upper parts mostly black and grey, 
which was supposed to be characteristic of Labrador birds. 
II. Mr. Bishop follows by separating the Canadian Grouse 
inhabiting N. British Columbia and Alaska from those met 
with in Maine. 
He says the female of C. c. osgoodi in breeding-plumage 
differs from the females found in Maine in having all the 
bars on the plumage cream- buff and greyish white instead of 
ochraceous white. 
Specimens in the British Museum Collection disprove 
this statement; for females fromNulato, Fort Simpson, and 
Jasper's House are indistinguishable from females from Maine 
and New Brunswick. 
III. Lastly, Mr. Norton correctly points out that C. c. 
labradoriusis a mere synonym of typical C. canadensis (Linn.), 
which was founded on birds from Hudson Bay ; but he is 
of opinion that birds from New England and parts of Canada 
are distinct and should bear the name of C. c. canace (Linn.). 
As already stated, I cannot admit this distinction, all 
the alleged differences in plumage being fully accounted 
for by season or age, and being in no way dependent on 
locality.
