The third of these described forms, C. a. rothschildi (1. c.) is also 

 an inmate of the London Zoological Gardens. The locality from which 

 it came is not known, and, as is the case of all these described animals, 

 it is young. This example is not an albino, as the general color of the 

 body and limbs is a uniform black with a slaty tinge on the whiskers, 

 and black eyelids. This appears to be only another phase of coloring 

 differing slightly from the typical style which members of this species 

 exhibit. So far as I am aware no two individuals, having a more or 

 less strong tendency to albinism, have agreed in the distribution of 

 their markings, or in the amount of white or black exhibited, and it is 

 evident that the coloring of their pelage or the lack of it, is purely an 

 individual trait. C. a. rothschildi however, is nearer in its coloring to 

 typical C. aterrimus than any of the styles that have been given a 

 separate name.
