  Two 
  specimens 
  examined. 
  

  

  Apart 
  from 
  its 
  small 
  size, 
  this 
  handsome 
  squirrel 
  is 
  at 
  once 
  

   distinguished 
  by 
  its 
  pale 
  colour. 
  It 
  gives 
  me 
  great 
  pleasure 
  

   to 
  associate 
  with 
  it 
  the 
  name 
  of 
  Mrs. 
  Elbert, 
  who 
  accompanied 
  

   her 
  husband 
  during 
  his 
  expedition. 
  

  

  Acanthion

  Smaller 
  than 
  A. 
  javanicum 
  and 
  with 
  a 
  very 
  different 
  

   skull. 
  

  

  Externally 
  very 
  much 
  like 
  A. 
  javanicum, 
  somewhat 
  paler 
  

   on 
  neck 
  and 
  anterior 
  portion 
  of 
  back, 
  the 
  brown 
  with 
  a 
  slight 
  

   purplish 
  hue. 
  Spines 
  of 
  posterior 
  back 
  with 
  more 
  black, 
  

   usually 
  with 
  black 
  or 
  very 
  short 
  white 
  tips.
