"Head, back and cheeks are ash colored, slightly mixed with brown 

 on the hips and rump, the hairs being everywhere annulated with white, 

 and thus partially speckled ; the arms, forearms, thighs, legs and paws 

 are black ; the whole of the chin and throat, pure unmixed white ; the 

 cheeks, whiskers, and head grizzled ash, like the back and sides ; the 

 face apparently grayish blue and the belly ash colored. The tail is 

 about the length of the body, but has lost the greater part of the hair ; 

 what remains, however, is of the same color as the body."
