Antlers large and complex, without sub-basal snag, 

 forking in a regularly dichotomous manner, with tlie upper, 

 or posterior prong moic or less exceeding the lower, or 

 anterior, one in size ; metatarsal gland and tvift absent ; tail 

 short ; face moderately long ; face-glands well developed, 

 and gland-pits in skull rather large and deep ; foot-glands 

 not definitely known ; upper canines generally present in 

 adult males; size large or rather small; young uniformly 

 coloured or spotted. The absence of the metatarsal gland 

 and of a sub-basal snag to tlie regularly dichotomous antlers 

 are the most easily recognised features of this genus, which 

 in most other respects resembles Odocoilcus, although the 

 nature of the foot-glands and their presence or absence in 

 the fore-limbs does not appear to be definitely known. . 



The two species are distinguishable as follows : — 



A. Size large, antlers complex, hair on withers directed 



backwards, colour deep rufous B. dichotomus. 



B. Size smaller, antlers simpler, hair on withers 



directed forwards, colour yellowish -brown B. bezoarticns.
