A NEW SPECIES OF CARIBOU 



lower lip silvery white; between the jaws, entire 

 throat and sides of neck and over shoulders 

 varying from brownish gray in calves of the 

 year to white in fully mature examples; backs 

 of ears and along the posterior portion of head 

 and neck light grayish, being gradually displaced 

 by white or yellowish gray towards the shoul- 

 ders; a broad band of grayish buff or buffy 

 white extending diagonally from the color of the 

 shoulders to the region of the elbow and along 

 the sides to flank. (The last named characters 

 vary with the age of the animal, but are pro- 

 nounced in all examples from a calf of the year 

 to fully adult specimens — the markings on the 

 shoulders and sides being the most prominent 

 in young animals, the white neck being acquired 

 upon full development.) A band of dark brown 

 separating light stripe on sides from white of 

 underparts. 



Hoofs, small; antlers, differing in type when 

 compared with osborni and stonei, notably in the 

 length of single brow tine and the formation of 

 the first branch. 



Skull, excessive anterior cleft and flattening 

 of nasals; length and backward curvature of the 

 paroccipital processes; width of lachrymals, 

 smooth and rounded surface of processes above 

 m^ and m^ (see illustration for dentition).
