  This 
  is 
  a 
  much 
  lighter 
  colored 
  species 
  than 
  L. 
  petaurista, 
  show- 
  

   ing 
  much 
  less 
  black 
  on 
  the 
  upper 
  parts. 
  The 
  type 
  in 
  Berlin 
  Museum 
  is 
  

   a 
  baby, 
  not 
  half 
  grown. 
  Herr 
  Matschie 
  has 
  made 
  this 
  a 
  subspecies 
  of 
  

   L. 
  petaurista 
  Schreb., 
  but 
  as 
  I 
  have 
  never 
  seen 
  any 
  intermediate 
  

   between 
  it 
  and 
  that 
  species, 
  it 
  seems 
  best, 
  for 
  the 
  present 
  at 
  least, 
  to 
  

   accord 
  it 
  specific 
  rank.
