  LASIOPYGA 
  

  

  This 
  is 
  a 
  peculiarly 
  colored 
  monkey, 
  showing 
  an 
  affinity 
  to 
  mem- 
  

   bers 
  of 
  various 
  groups, 
  and 
  yet 
  seems 
  distinct 
  from 
  them 
  all. 
  Mr. 
  

   Pocock 
  in 
  his 
  paper, 
  (1. 
  c.) 
  has 
  made 
  L. 
  thomasi 
  (Matschie), 
  a 
  sub- 
  

   species 
  of 
  L. 
  i/hoesti, 
  but 
  this 
  does 
  not 
  seem 
  to 
  be 
  the 
  proper 
  place 
  

   for 
  that 
  species, 
  as 
  Matschie's 
  type 
  is 
  very 
  like 
  L. 
  preussi 
  but 
  paler 
  on 
  

   the 
  back, 
  and 
  the 
  tail 
  is 
  lighter; 
  the 
  limbs, 
  however, 
  and 
  shoulders 
  

   are 
  black 
  as 
  in 
  L. 
  i/hoesti.

  The 
  type 
  is 
  a 
  young 
  animal, 
  but 
  it 
  is 
  quite 
  different 
  in 
  appearance 
  

   from 
  any 
  of 
  the 
  known 
  species, 
  so 
  different 
  in 
  fact, 
  I 
  hardly 
  know 
  

   where 
  to 
  place 
  it, 
  for 
  like 
  L. 
  i/hoesti 
  it 
  does 
  not 
  seem 
  to 
  have 
  any
