of the same character and colour as that on the top 

 of the head ; tarsi whitish at the base, grizzled with 

 white and dark brown in the middle, and the hairs 

 over the toes are of a very dark brown colour almost 

 black ; a transverse whitish mark is observable on 

 the haunches ; about three inches of the tail, at the 

 base, is covered with fur of the same texture and

 ingly clothed, the hairs are very small and rather
