  Misled 
  by 
  the 
  unfortunate 
  geographical 
  teriu 
  " 
  Lower 
  

   Siam/^ 
  he 
  has 
  described 
  another 
  "• 
  species," 
  F. 
  capitulis 
  

   (Vol. 
  II. 
  p. 
  235), 
  as 
  inhabiting 
  Trong 
  and 
  Telibun 
  Island. 
  

  

  Trong, 
  or 
  rather 
  Trang, 
  is 
  a 
  district 
  on 
  the 
  mainland 
  o£ 
  

   the 
  Peninsula, 
  about 
  50 
  miles 
  north 
  of 
  Langkawi, 
  and 
  

   Telibon 
  an 
  island 
  off 
  its 
  coast, 
  separated 
  by 
  an 
  exceedingly 
  

   shallow 
  channel. 
  

  

  According 
  to 
  our 
  author, 
  therefore, 
  despite 
  the 
  fact 
  that 
  

   (pp. 
  iv, 
  V, 
  Preface) 
  "intermediates 
  between 
  what 
  are 
  re- 
  

   corded 
  as 
  species 
  have 
  rarely 
  been 
  found 
  in 
  this 
  order,^' 
  and 
  

   that 
  " 
  on 
  the 
  mainland 
  where 
  there 
  is 
  no 
  evidence 
  of 
  a 
  

   gradation 
  from 
  one 
  form 
  to 
  another 
  subspecies 
  may 
  not 
  be 
  

   accepted,^^ 
  we 
  have 
  the 
  extremely 
  curious 
  case 
  of 
  discon- 
  

   tinuons 
  distribution 
  of 
  Macacus 
  irus 
  * 
  separated 
  in 
  a 
  

   continuous 
  land-area 
  by 
  an 
  intrusive 
  form, 
  P. 
  capitalis, 
  which 
  

   presumably 
  does 
  not 
  intergrade, 
  as 
  it 
  is 
  named 
  binomially. 
  

  

  There 
  is 
  the 
  further 
  case 
  of 
  discontinuous 
  distribution 
  

   of 
  M. 
  fascicularis 
  met 
  with 
  on 
  Sumatra 
  and 
  the 
  islands 
  of 
  

   Terutau 
  and 
  Langkawi. 
  

  

  In 
  reality, 
  the 
  whole 
  treatment 
  of 
  the 
  group 
  forms 
  a 
  most 
  

   admirable 
  example 
  of 
  the 
  danger 
  of 
  working 
  with 
  insufficient 
  

   material 
  and 
  with 
  imperfect 
  knowledge 
  of 
  the 
  geography 
  of 
  

   the 
  area 
  dealt 
  with. 
  

  

  Genus 
  Pygathrix 
  [Presbytis 
  or 
  Semnopithecus) 
  . 
  

  

  Dr. 
  Elliot 
  has 
  thrown 
  the 
  section 
  containing 
  the 
  species 
  

   lately 
  known 
  as 
  femoralis 
  {uomen 
  nuduni) 
  into 
  hopeless 
  

   confusion. 
  

  

  The 
  specimen 
  on 
  which 
  the 
  name 
  femoralis 
  was 
  founded 
  

   was 
  originally 
  obtained 
  somewhere 
  in 
  Sumatra 
  by 
  Raffles, 
  

   though 
  in 
  his 
  paper 
  in 
  Trans. 
  Linn. 
  Soc. 
  vol. 
  xiii. 
  (1822), 
  

   are 
  given, 
  evidently 
  in 
  error, 
  the 
  localities 
  Pulau 
  Peuaug 
  

   and 
  Singapoie. 
  Later, 
  Miiller 
  and 
  Schlegel 
  described, 
  and 
  

   figured 
  as 
  Semnopithecus 
  sumatrana, 
  a 
  form 
  from 
  Mount 
  

   Ophirin 
  the 
  Padang 
  Highlands, 
  W. 
  Sumatra 
  (subsequently, 
  

   however, 
  referred 
  by 
  the 
  latter 
  to 
  S. 
  femoralis) 
  f, 
  which 
  is 
  

   clearly 
  distinguishable 
  from 
  the 
  form 
  inhabiting 
  the 
  Peninsula 
  

   and 
  adjacent 
  islands, 
  which 
  is 
  P. 
  neglecta 
  (Schlegel) 
  %. 
  

  

  The 
  Bornean 
  representative 
  is 
  described 
  by 
  Miiller 
  and 
  

   Schlegel 
  as 
  P. 
  chrysomelas. 
  

  

  In 
  dealing 
  with 
  what 
  he 
  calls 
  P. 
  femoralis 
  (Horsf.) 
  

  

  * 
  We 
  ourselves 
  do 
  uot 
  possess 
  any 
  examples 
  of 
  the 
  Common 
  Macaque 
  

   from 
  Burma 
  and 
  Tenasserim, 
  and 
  are 
  therefore 
  not 
  in 
  a 
  position 
  to 
  deny 
  

   the 
  statement 
  that 
  the 
  M. 
  irus 
  occwvs 
  there.
