  Those 
  taken 
  by 
  the 
  collector 
  in 
  the 
  

   flesh 
  were:— 
  Total

   The 
  emendation 
  is 
  not 
  in 
  the 
  direction 
  of 
  accuracy, 
  as 
  no 
  

   full-grown 
  monkey 
  in 
  this 
  group 
  has 
  so 
  small 
  a 
  foot 
  as 
  

   indicated 
  by 
  Dr.

  Pygatkrix

  Elliot 
  (Vol. 
  III.

  55), 
  is 
  a 
  pure 
  

   synonym 
  of 
  P 
  y 
  gathrix 
  siamensis 
  , 
  Miiller 
  & 
  Schlegel 
  (Vol. 
  III. 
  

   p.

  Schlegel, 
  in 
  his 
  monograph 
  on 
  tlie 
  monkeys 
  (Alus. 
  

   Pays-Bas, 
  1876, 
  p. 
  38), 
  expressly 
  states 
  that 
  the 
  types 
  were 
  

   collected 
  by 
  Diard 
  in 
  Malacca, 
  and 
  the 
  locality 
  Siam 
  was 
  

   ascribed 
  to 
  them 
  in 
  error, 
  as 
  it 
  also 
  was 
  to 
  certain 
  specimens 
  

   of 
  Pygatkrix 
  ohscura 
  obtained 
  by 
  the 
  same 
  collector 
  (p. 
  49). 
  

   The 
  locality

  Kcka,^' 
  given 
  by 
  Dr. 
  Elliot 
  for 
  his 
  type 
  of 
  

   P. 
  nub/gena, 
  is 
  merely 
  the 
  native 
  name 
  of 
  the 
  species, 
  as 
  

   noted 
  by 
  Dr. 
  Cantor 
  on 
  the 
  label. 
  The 
  specimen

  Museum

   (Vol.

  the

  Pygathrix 
  rhionis

  has 
  notliing 
  to 
  do 
  with 
  

   P. 
  obscura 
  as 
  stated, 
  but 
  is 
  closely 
  allied 
  to 
  P. 
  siamensis 
  and 
  

   P. 
  dileda, 
  and 
  its 
  affinities 
  are 
  correctly 
  given 
  by 
  Miller

  original 
  description. 
  

  

  Pygathrix 
  cristata 
  (Vol. 
  III. 
  p. 
  79) 
  is 
  a 
  common 
  monkey 
  

   in 
  suitable 
  localities 
  along 
  the 
  western 
  coast 
  of 
  the 
  Malay 
  

   Peninsula, 
  and 
  is 
  not 
  confined 
  to 
  Sumatra 
  as 
  stated. 
  

  

  Dr. 
  Elliot 
  cites 
  Muleyit 
  in 
  Tenasserim 
  as 
  a 
  locality 
  for 
  

   Pygathrix 
  obscura 
  (Vol. 
  III. 
  p 
  53), 
  and 
  then 
  describes 
  the 
  

   speciuiens 
  which 
  are 
  the 
  authority 
  for 
  this 
  locality 
  as 
  a 
  new 
  

   species, 
  Pygathrix 
  crepuscula 
  (Vol. 
  III. 
  p. 
  84), 
  which 
  may 
  

   be 
  valid 
  if 
  regarded 
  as 
  a 
  subspecies 
  of 
  P. 
  obscura. 
  

  

  The 
  type 
  of 
  Pygathrix 
  crepuscula 
  wroughtoni 
  (Vol. 
  III. 
  

   p. 
  85), 
  which 
  one 
  of 
  us 
  has 
  examined, 
  is 
  jjractically 
  identical 
  

   with 
  specimens 
  of 
  P. 
  obscura 
  from 
  the 
  Patani 
  coast, 
  N.E. 
  

   Malay 
  Peninsula. 
  Judging 
  from 
  the 
  dimensions, 
  it 
  is 
  almost 
  

   certainly 
  a 
  female, 
  and 
  should 
  not 
  have 
  been 
  described, 
  except 
  

   on 
  a 
  reasonably 
  large 
  series. 
  

  

  Passing 
  to 
  the 
  llylobatidre, 
  or 
  Gibbons, 
  we 
  may 
  note 
  that 
  

   the 
  Malay 
  Peninsula 
  is 
  omitted 
  from 
  the 
  distribution 
  of 
  

   H. 
  agilis 
  (Vol. 
  III. 
  p. 
  160), 
  though 
  its 
  occurrence 
  has 
  been
