  Remarks. 
  — 
  We 
  have 
  long 
  suspected 
  that 
  specimens 
  of 
  this 
  

   type 
  of 
  squirrel 
  from 
  the 
  mountain 
  ranges 
  of 
  the 
  southern 
  

   two-thirds 
  of 
  the 
  Malay 
  Peninsula 
  were 
  not 
  strictly 
  con- 
  

   specific 
  with 
  Sc. 
  rubeculus 
  from 
  Trang. 
  The 
  receipt 
  of 
  a 
  

   series 
  of 
  eight 
  from 
  the 
  mountains 
  of 
  Bandon 
  shows 
  that 
  

   the 
  southern 
  form 
  is 
  sufficiently 
  distinct 
  to 
  merit 
  separation, 
  

   and 
  we 
  have 
  accordingly 
  named 
  it 
  after 
  Sir 
  Arthur 
  Young, 
  

   K.C.M.G., 
  Governor 
  of 
  the 
  Straits 
  Settlements 
  and 
  High 
  

   Commissioner, 
  Malay 
  States, 
  who 
  has 
  recently 
  ascended 
  

   Gunong

  which

  has

  it,

   that 
  the

  animal 
  cannot 
  be
