surements are taken from the specimens which I have received 
from Hudson's Bay, one of each bird, and all these apparently 
full grown : — 
B. Cana- B. leu- B. Hut- 
densis. colcema. chinsii'^. 
Length of bird, from tip of bill to end of ^^^^^^^ I^^^^^' 
tail feathers, measured along the back. 
Length of upper mandible, from tip to 
where the downy plumage begins, 
measured along the middle, . 
Breadth of upper mandible across the 
nostrils, .... 
Height of upper mandible at the nos- 
trils, .... 
Length of head, from base of the middle 
of the mandibles to the occiput. 
Length of wing, from carpal joint to end 
of longest wing feathers, 
Length of tarsus, 
Length of first phalanx of middle toe, . 
There is also a slight difference in the arrangement of the 
scuta on the phalanges of the Canada goose and leucolcema^ 
though not very decided. In the next species this is much 
more marked. 
B . HutcMnsli ? Richard and Swain. (Plate 1).— The pre- 
ceding measurements show that this is a much smaller bird, 
and it will be observed that the proportions are different. The 
bill is proportionally much smaller, narrower, and deeper, 
than in the other two. The colour is much the same as 
in the Canada goose, but darker and richer on the back, 
and with a greater shade of fawn on the belly, instead of 
the lavender colour in the Canada goose, owing to the colour 
of the terminations of the abdominal feathers. The cravat- 
patch wants the black flecking which Captain Ord informs me 
he has found to be a constant character in his specimens of 
the Canada goose. 
There is a marked difference in the mode of arrangement 
of the scuta on the first phalanx of the middle toe. In the 
two preceding species there are three oblique transverse scuta 
at the distal extremity, those further back being broken up into 
polygonal plates ; while in this species there are seven broad
