  as 
  no

  in

  it 
  cannot 
  be 
  recognized, 
  

   especially 
  as 
  the 
  very 
  brief 
  description,

  On

  (Vol. 
  I.) 
  the 
  geographical 
  range 
  of 
  N. 
  malai- 
  

   anus 
  is 
  said 
  to 
  be 
  " 
  Chitragong, 
  through 
  Arakan 
  as 
  far 
  south 
  

   as 
  Tringganu, 
  Lower 
  Siam." 
  

  

  It 
  is 
  obvious 
  that 
  two 
  local 
  races 
  cannot 
  occupy 
  the 
  same 
  

   area, 
  and 
  it 
  may 
  also 
  be 
  remarked 
  that 
  Trengganu, 
  a 
  pro- 
  

   tected 
  state 
  in 
  the 
  central 
  section 
  of 
  the 
  Malay 
  Peninsula, 
  

   is 
  not 
  " 
  Lower 
  Siam/^ 
  and 
  that 
  the 
  range 
  of 
  N. 
  malaianus 
  

   extends 
  over 
  the 
  whole 
  of 
  the 
  Malay 
  Peninsula 
  as 
  well 
  as 
  

   the 
  islands 
  of 
  Singapore 
  and 
  Penang, 
  and 
  is 
  not 
  restricted 
  

   to 
  the 
  northern 
  half, 
  as 
  Dr. 
  Elliot 
  would 
  appear 
  to 
  infer. 
  

   Specimens 
  from 
  Johore, 
  collected 
  by 
  Dr. 
  W. 
  L. 
  Abbott, 
  are 
  

   recoided 
  by 
  Lyon 
  (Proc. 
  U.S. 
  Nat. 
  Mus. 
  xxxi. 
  p. 
  5<37, 
  

   190G). 
  

  

  Pithecus 
  rufescens. 
  (Vol. 
  II. 
  p. 
  193.) 
  

  

  It 
  is 
  only 
  the 
  females 
  and 
  immature 
  of 
  this 
  species 
  that 
  

   are 
  bright 
  red 
  ; 
  the 
  adult 
  male 
  is 
  seal-brown 
  with 
  very 
  long 
  

   hair 
  on 
  the 
  shoulders. 
  

  

  The 
  range 
  is 
  from 
  Muleyit 
  in 
  Tenasserim 
  to 
  Trang 
  and 
  

   Patelung 
  in 
  the 
  northern 
  parts 
  of 
  the 
  Malay 
  Peninsula, 
  the 
  

   former 
  locality 
  having 
  been 
  duly 
  recorded 
  by 
  Bonhote 
  

   (P.Z. 
  S. 
  1900, 
  p. 
  871). 
  

  

  Pithecus 
  adustus. 
  (Vol. 
  II. 
  p. 
  206.) 
  

  

  This 
  form 
  can 
  only 
  doubtfully 
  be 
  maintained, 
  as 
  animals, 
  

   even 
  from 
  the 
  south 
  of 
  the 
  Malay 
  Peninsula, 
  are 
  frequently 
  

   annnlated. 
  Dr. 
  Elliot 
  gives 
  it 
  as 
  representing 
  the 
  Suuiatran 
  

   animal 
  in 
  Tenasserim, 
  but 
  on 
  the 
  preceding 
  pages 
  gives 
  the 
  

   range 
  of 
  that 
  form, 
  P. 
  nemestriaus, 
  as 
  Southern 
  Burma, 
  

   Malay 
  Peninsula, 
  &c. 
  If 
  sufficient 
  variation 
  from 
  the 
  

   typical 
  Sumatran 
  form 
  should 
  be 
  proved, 
  all 
  mainland 
  

   specimens 
  will 
  probably 
  have 
  to 
  bear 
  the 
  name 
  adustus, 
  but 
  

   existing 
  material, 
  which 
  is 
  considerable, 
  tends 
  to 
  show 
  the 
  

   contrary. 
  

  

  In 
  1908 
  the 
  Federated 
  Malay 
  States 
  Museums 
  undertook 
  

   a 
  collecting 
  expedition 
  of 
  some 
  months' 
  duration 
  to 
  the 
  

   llhio-Lingga 
  Archipelago 
  and 
  the 
  adjacent 
  parts 
  of 
  Johore 
  

   and 
  Singapore 
  Island. 
  

  

  The 
  collection 
  of 
  mammals 
  obtained 
  was 
  very 
  large, 
  

   &nd 
  a 
  fully 
  representative 
  set 
  was 
  presented 
  to 
  the 
  British
