In his ‘Horns and Hoofs,’ Mr. Lydekker casts some doubt as to the real 
distinctness of ©. maria from C. leucotis, but on this point we can assure him 
there is no room for hesitation. No one who examines our beautiful picture 
of this species (Plate XXXVII.), drawn by Smit from Mr. Wolf’s original 
sketch, will fora moment deny its perfect distinctness from Cobus leucotis 
and from every other known species of the group. 
August, 1896.
