Old male kluane covipared with old male latifrons: Size essentially 

 same; frontal region much narrower and more highly arched ; postorbital 

 processes much broader and more strongly decurved ; sagittal crest longer, 

 arched instead of straight; rostrum more elevated and more rounded 

 above; nasals convex instead of flat in cross section. Zygomata less 

 widely outspreading and less bowed; coronoid blade narrower. 



Adult female kluane compared with adult female latifrons: Skull much 

 smaller, shorter, and more delicate. Frontal shield much narrower; 

 vault of cranium more arched over posterior frontals; rostrum lower; 

 zygomata less widely outstanding ; palate much narrower ; lower molars 

 and canines approximately same size; last upper molar much smaller. 

 While the skull of female kluane is much smaller than that of latifrons, 

 the lower jaw is nearly the same size. 



Old male kluane (the type) compared with old male pallasi (the 

 type) : Size decidedly greater; skull about an inch longer and much more 

 highly arched, with conspicuously longer braincase and longer sagittal 

 crest ; crest strongly arched instead of nearly straight ; postorbitals very 

 much larger, broader, and more strongly decurved ; f ronto-nasal region 

 much more elevated and less dished; rostrum much higher, rounded 

 above instead of depressed ; palate much longer, more arched and more 

 concave; lower jaw much longer ; coronoid higher. 



Adult female kluane compared with adult female pallasi : Skulls very 

 much alike in size and appearance (that of kluane slightly larger) but 

 teeth strikingly different. In kluane canines larger; molars very much 

 larger. 



Skull measurements {(? old, type). — Basal length 317 mm.; occipito- 

 nasal length 324; palatal length 177; zygomatic breadth 210; interorbital 

 breadth 85.

 postorbitals. Frontal shield of moderate breadth, shallowly sulcate 

 medially, swollen over orbits, short-pointed posteriorly; rostrum long,
