THE most striking feature in this animal is the size 

 of the head j and the effect is heightened by the short 

 or shorn-like white hairs which cover it ; the breast 

 and belly, sides of the cheeks, and whole front before

 of black and brown, disposed in irregular patches, 

 covers the back and rest of the body. F. Cuvier was
