t The specimens procured by Mr. Powell-Cotton have the tail for more than 

 basal half dark gray, and but little white on the buttocks. One is a fully adult 

 male, the other young. Although appearing so different from typical guereza 

 in these respects, for lack of material for comparison I leave them under that 

 name.
