this region are sometimes dun-coloured at the root, 

 greyish white in the centre, and brownish red, 

 shading into the dark brown tip. The hair on the 

 lips is sometimes of a blackish brown, sometimes 

 whitish, or both colours are found together. The 

 hair growing at the sides of the face is grey below, 

 dark brown or almost black above. On the neck 

 and shoulders the hair is of a grey colour at the 

 root, and gradually becomes lighter towards the tip.

 colour. In others the forearms, hands, slianks, and 

 feet are covered, like the rest of the body, with grey 

 ^and brown hair intermingled.
