  But 
  Linnaeus' 
  Simla 
  cethiops 
  is 
  a 
  Lasiopyga, 
  and 
  has 
  nothing 
  to 
  do 
  with 
  

   the 
  members 
  of 
  the 
  present 
  genus, 
  and 
  there 
  is 
  no 
  law 
  known 
  that 
  

   forbids 
  the 
  same 
  specific 
  name 
  to 
  be 
  given 
  to 
  two 
  species 
  of 
  different 
  

   genera. 
  C. 
  ^ethiops 
  (Schreb.), 
  is 
  therefore 
  perfectly 
  applicable 
  to 
  a 
  

   Cercocebus, 
  and 
  ^ethiops 
  Linnaeus 
  to 
  a 
  Lasiopyga, 
  if 
  the 
  species 
  

   can 
  be 
  determined, 
  which 
  in 
  this 
  case, 
  unfortunately 
  cannot 
  be, 
  and 
  the 
  

   confusion 
  that 
  has 
  existed 
  among 
  Authors 
  in 
  regard 
  to 
  this 
  name, 
  has 
  

   arisen 
  from 
  the 
  supposition 
  that 
  Linnaeus 
  and 
  Schreber 
  referred 
  to 
  

   animals 
  in 
  the 
  same 
  genus, 
  which 
  is 
  not 
  the 
  fact.

  Pocock, 
  (1.

  and

  make 
  this 
  species 
  the 
  

   same 
  as 
  C. 
  cethiops 
  GeofTroy, 
  (E. 
  Geoffroy 
  I 
  suppose 
  is 
  intended). 
  This 
  

   is 
  not 
  the 
  fact, 
  for 
  the 
  C. 
  cethiops
