  now 
  considered 
  to 
  belong 
  to 
  various 
  genera, 
  as 
  well 
  as 
  to 
  

   Lasiopyga. 
  The 
  species 
  of 
  Cercocebus 
  are: 
  

   (C.) 
  atys 
  undeterminable; 
  C. 
  ^ethiops 
  (Schreber), 
  and 
  C. 
  

   fuliginosus 
  Geoff., 
  also 
  = 
  C. 
  ^ethiops

  Like

  Author, 
  the

  one 
  includes 
  the 
  species 
  

   of 
  Cercocebus 
  in 
  Cercopithecus 
  = 
  (Lasiopyga), 
  as 
  follows: 
  

   (C.) 
  fuliginosus 
  = 
  C. 
  jethiops 
  (Schreber); 
  C. 
  ^ethiops

  F.

  = 
  C. 
  ^ethiops 
  (Schreb.) 
  ; 
  

   and 
  C. 
  atys 
  possibly 
  an 
  albinistic 
  individual 
  of 
  C. 
  jethiops, 
  but 
  

   undeterminable.

  redescribed

  the

  however 
  attributed

  have 
  not 
  found 
  that

  I. 
  Geoffroy 
  

   employed 
  this 
  name 
  for 
  the 
  species.
