The colour of the fur in this species varies to an extraordinary 
degree, and before this fact was recognised, a number of sup- 
posed species, founded on the colour of the animals alone, 
were described. In course of time, however, as specimens 
were obtained in greater number, it became evident that the 
variation was only in the colour of the fur, and that there 
was none in their anatomical and osteological structure to 
warrant their being considered distinct species. They have, 
therefore, all been now classified by Professor Milne-Edwards 
and M. Grandidier in their great work on the Natural History
