  The 
  type 
  is 
  a 
  young 
  animal 
  with 
  a 
  black 
  nose, 
  but 
  some 
  adults 
  

   have 
  a 
  white 
  nose 
  patch. 
  This 
  species 
  is 
  not 
  nearly 
  allied 
  to 
  L. 
  

   petaurista 
  as 
  some 
  writers 
  have 
  believed, 
  the 
  only 
  similarity 
  in 
  color- 
  

   ing 
  between 
  them 
  being 
  the 
  black 
  frontal 
  band 
  going 
  around 
  the 
  head. 
  

   It 
  is 
  nearer 
  in 
  coloring, 
  so 
  far 
  as 
  the 
  dorsal 
  region 
  is 
  concerned,
