This and the next race are dark-coloured mountain 

 caribou, with antlers of the Barren-Ground type, but the 

 bodily size much greater than in R. t. arcticus. 



The present race is characterised by the brown colour of 

 the autumn coat and the large amount of white on the rump 

 and the hind half of the under surface of the body; the 

 whole neck and shoulders, as well as the back and limbs, 

 being much lighter than in the Selkirk race. As the antlers 

 correspond in form and proportion with those of the Barren- 

 Ground caribou, they serve to connect the Selkirk race with 

 the latter.
