  PITHECUS 
  

  

  third 
  vertebra, 
  so 
  it 
  probably 
  originally 
  had 
  a 
  caudal 
  appendage 
  as 
  long 
  

   as 
  tcheliensis 
  at 
  least. 
  The 
  tufts 
  of 
  hairs 
  on 
  the 
  ears, 
  from 
  which 
  

   this 
  species 
  obtained 
  its 
  name, 
  have 
  now 
  disappeared 
  from 
  the 
  type, 
  

   and 
  the 
  ears 
  are 
  nearly 
  bare. 
  

  

  Macacus 
  tcheliensis 
  of 
  Milne-Edwards, 
  from 
  the 
  Province 
  of 
  

   Tche-li, 
  North-eastern 
  China, 
  was 
  described 
  from 
  a 
  female 
  which 
  is 
  

   in 
  the 
  Paris 
  Museum. 
  It 
  is 
  undoubtedly 
  the 
  same 
  as 
  the 
  present 
  

   species 
  and 
  consequently 
  extends 
  the 
  range 
  of 
  M. 
  lasiotis 
  farther 
  to 
  

   the 
  west, 
  even 
  to 
  the 
  borders 
  of 
  Thibet.
