  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.
