  ears. 
  This 
  species 
  often 
  presents, 
  in 
  various 
  degrees, 
  different 
  stages 
  

   of 
  albinism, 
  and 
  certain 
  individuals 
  thus 
  lacking 
  in 
  color 
  have 
  been 
  

   described 
  as 
  distinct 
  species, 
  and 
  have 
  added 
  considerably 
  to 
  the 
  

   synonymy. 
  I 
  have 
  seen 
  all 
  these 
  so 
  called 
  forms, 
  and 
  some 
  others 
  differ- 
  

   ing 
  slightly 
  which 
  happily 
  had 
  escaped 
  baptism. 
  The 
  first 
  of 
  these 
  albinos 
  

   was 
  the 
  C. 
  congicus 
  of 
  Sclater 
  (1. 
  c). 
  The 
  type 
  of 
  this 
  form 
  was 
  

   living 
  in 
  the 
  Zoological 
  Gardens 
  of 
  Antwerp, 
  presented 
  in 
  1899 
  by 
  M. 
  

   F. 
  Fuchs, 
  the 
  then 
  Governor 
  of 
  the 
  Congo 
  Free 
  State. 
  It 
  was 
  a 
  female 
  

   and 
  was 
  conspicuous 
  for 
  the 
  prominent 
  crest 
  arising 
  from 
  the 
  top 
  of 
  

   the 
  head 
  and 
  the 
  long 
  hair 
  on 
  the 
  cheeks. 
  It 
  resembles 
  somewhat 
  in 
  

   the 
  coloring 
  of 
  the 
  head 
  C. 
  hamlyni, 
  but 
  the 
  body 
  is 
  all 
  black. 
  This 
  

   specimen 
  died 
  and 
  is 
  now 
  in 
  the 
  Museum 
  of 
  the 
  Royal 
  Zoological 
  

   Society 
  in 
  Antwerp. 
  On 
  a 
  recent 
  visit 
  to 
  the 
  Antwerp 
  Gardens 
  I 
  saw 
  

   another 
  example, 
  the 
  third, 
  as 
  I 
  was 
  informed 
  by 
  M. 
  l'Hoest, 
  the 
  

   Director, 
  that 
  they 
  had 
  received. 
  It 
  was 
  a 
  male 
  and 
  about 
  half 
  grown, 
  

   and 
  differs 
  somewhat 
  from 
  the 
  type, 
  in 
  having 
  the 
  chest 
  black, 
  not 
  

   white 
  ; 
  the 
  flesh 
  colored 
  face 
  and 
  ears 
  were 
  much 
  blotched 
  with 
  black- 
  

   ish 
  brown, 
  and 
  the 
  flesh 
  colored 
  hands, 
  and 
  general 
  appearance 
  of 
  the 
  

   animal, 
  strongly 
  suggested 
  albinistic 
  coloration. 
  It 
  is 
  more 
  white 
  than 
  

   black, 
  and 
  may 
  be 
  described 
  as 
  follows: 
  General 
  color 
  white; 
  top 
  of 
  

   head 
  and 
  pointed 
  crest, 
  chest, 
  and 
  abdomen 
  black 
  ; 
  inner 
  side 
  of 
  fore- 
  

   arm 
  and 
  back 
  blackish; 
  rest 
  of 
  body 
  and 
  tail 
  white; 
  face, 
  ears, 
  hands 
  

   and 
  feet 
  flesh 
  color, 
  the 
  first 
  two 
  blotched 
  with 
  brownish 
  black. 
  Crest 
  

   standing 
  upright; 
  whiskers 
  very 
  large 
  partly 
  covering 
  the 
  ears, 
  and 
  

   standing 
  outward 
  from 
  the 
  head. 
  

  

  The 
  individual 
  representing 
  the 
  type 
  of 
  C. 
  hamlyni 
  Pocock 
  (1. 
  c.) 
  

   is 
  living 
  (1909) 
  in 
  the 
  Gardens 
  of 
  the 
  Zoological 
  Society 
  of 
  London, 
  

   and 
  is 
  a 
  female 
  only 
  partially 
  white. 
  It 
  is 
  stated 
  to 
  have 
  come 
  from 
  

   the 
  "Upper 
  Congo," 
  very 
  likely 
  from 
  Stanley 
  Falls 
  or 
  its 
  vicinity.
