NEW ENGLAND ZOOLOGICAL CLUB 
THE LABRADOR SPRUCE GROUSE. 
BY OUTRAM BANGS. 
WHILE at Hamilton Inlet, Labrador, in the summer of 1895, 
Mr. C. H. Goldthwaite collected a series of nine skins of spruce 
grouse. Although I always thought these birds represented a form 
different from true Canachites canadensis, they have lain in our 
collection until now, awaiting an opportunity for actual compari- 
son with breeding birds from other places. Lately Mr. William 
Brewster and I compared them carefully with his fine material, 
which includes a set of breeding birds from Lake Umbagog, 
Maine. ‘The Labrador form proves to be different, the differences 
being most noticeable in the females. ‘The Labrador birds are 
constantly much less suffused with buffy or ochraceous through- 
out, being more nearly gray and black above and much whiter 
below. The males are closer to true C. canadensis, but show 
rather more white below, especially on the border of the throat. 
The Labrador bird may be called 
Canachites canadensis labradorius subsp. nov. 
Type, from Rigoulette, Hamilton Inlet, Labrador, 9 adult, in breeding 
plumage, no. 1501, coll. of E. A. and O. Bangs, collected July 31, 1895, by 
C. H. Goldthwaite. 
Subspecific characters.— Size of true C. canadensis or a little larger; adult 
male, summer plumage, similar to true C. canadensis, except that white markings 
on under parts and on border of throat are rather heavier, and gray markings
