the comparative proportions of C. montana dalli and C. montana, 

 as represented by a good mounted specimen of each:

The above measurements show that var. dalli is a heavier and 

 stockier form with more conspicuously corrugated horns hav- 

 ing a greater spread, with much longer hair, shorter hoofs and 

 less elevated "dew claws" than its southern relative. 



A comparison of the skulls of these two forms does not dis- 

 close differences which may not be due to age or other purely 

 individual causes. c. c. N.

A head obtained from the Stoneys is among the specimens 

 from Pincher Creek.

Common throughout most of the region visited. The skins 

 are purchased by the Saskatchewan traders for 5 cents each. 

 I do not think that they are traded in the North.
