  Great 
  confusion 
  has 
  existed 
  in 
  the 
  nomenclature 
  of 
  this 
  and 
  the 
  

   next 
  species 
  arising 
  from 
  two 
  causes, 
  one, 
  the 
  vain 
  efforts 
  of 
  Authors 
  

   to 
  employ 
  the 
  Linnaean 
  name 
  cethiops, 
  which 
  was 
  given 
  to 
  an 
  unde- 
  

   terminable 
  species 
  of 
  Lasiopyga, 
  for 
  this 
  or 
  the 
  following 
  species, 
  and 
  

   the 
  other, 
  the 
  ignoring 
  of 
  Schreber's 
  name 
  cethiops, 
  bestowed 
  upon 
  the 
  

   Mangabey, 
  called 
  by 
  E. 
  Geoffroy 
  some 
  thirty-two 
  years 
  later, 
  

   fuliginosus. 
  As 
  I 
  show 
  in 
  the 
  review 
  of 
  the 
  Linnaean 
  literature 
  of 
  

   Lasiopyga, 
  Simia 
  cethiops 
  Linn., 
  must 
  be 
  ruled 
  out 
  of 
  court, 
  as 
  having 
  

   no 
  standing, 
  for 
  although 
  it 
  probably 
  belongs 
  to 
  the 
  Petaurista 
  or 
  

   ^Lthiops 
  groups 
  in 
  that 
  genus, 
  yet 
  the 
  species 
  it 
  represents 
  is 
  quite 
  

   undeterminable. 
  

  

  Bates, 
  states 
  (1. 
  c.) 
  that, 
  in 
  southern 
  Cameroon, 
  "Monkeys 
  of 
  this 
  

   species 
  are 
  not 
  rare, 
  but 
  are 
  often 
  killed. 
  They 
  differ 
  from 
  those 
  of 
  

   the 
  common 
  kind 
  in 
  that 
  they 
  often 
  descend 
  to 
  the 
  ground 
  to 
  feed. 
  

   Their 
  call 
  is 
  very 
  different 
  from 
  that 
  of 
  the 
  Cercopithecus, 
  (Lasio- 
  

   pyga), 
  monkeys. 
  It 
  is 
  rather 
  shrill 
  and 
  ends 
  in 
  an 
  after 
  sound 
  like 
  

   that 
  made 
  while 
  drawing 
  in 
  the 
  breath 
  or 
  gasping." 
  Kerr 
  was 
  the 
  first 
  

   to 
  bestow 
  a 
  Latin 
  name 
  on 
  this 
  species, 
  founding 
  it 
  on 
  the 
  "Mangabey 
  

   a 
  collier 
  blanc" 
  of 
  Buffon 
  and 
  called 
  it 
  Simia 
  cethiops 
  torquata.
