The type in the Paris Museum is greatly faded from exposure to 

 the light, and there is not much more than a trace of the original 

 coloring left on the sides of body and shoulders, but more is to be 

 seen on the dorsal line and rump, although these parts are much paler 

 evidently than during the life of the animal. There are no markings on 

 the face, and only a pale narrow reddish yellow line on center of head 

 from between the ears. The hands and feet were probably silvery gray, 

 but now are a dirty or sooty gray, as the accumulated dust of many 

 years has obscured in a great degree the original coloring. The side 

 of the body turned away from the light in the case is darker than 

 the other, and shows more of the reddish or orange tint, but it 

 is impossible to say what was the original color. The head is paler 

 than the body and is a grayish white, same color as the arms and 

 legs.
