The type of T. senex Schimper and Pucheran, is in the Paris 

 Museum. It resembles T. gelada in most particulars but is of a pale 

 yellowish brown on sides of head, neck and hind limbs; tail entirely 

 brownish gray with an immense tuft of the same color ; middle of 

 crown, chocolate brown ; abdomen and belly ochraceous ; forearms, 

 hands and feet black; upper part of body and mantle blackish chocolate 

 brown grading into grayish white on borders of mantle ; upper edge 

 of thighs dark brown. The light colors exhibited may be partly due to 

 fading, but the specimen is considerably lighter on head and neck and 

 hind limbs than T. gelada, while the tail shows none of the black which 

 is the prevailing color on the tail of Riippell's species. But, however, 

 as the locality of the specimen is the same as that in which T. gelada 

 is found, and no second example agreeing with T. senex has been 

 procured since it was described, now half a century ago, it may safely 

 be considered that this type represents merely an individual variation 

 and not a distinct species. The skull is in the specimen. 



The Gelada is a very handsome species, and the long heavy mane 

 which covers the shoulders and upper part of the body, gives it a 

 majestic appearance. The bare spot on the chest is very brightly
