  albigena 
  he 
  left 
  it 
  as 
  probably 
  a 
  subspecies, 
  but 
  without 
  a 
  name. 
  In 
  

   the 
  Berlin 
  Museum 
  he 
  found 
  additional 
  skins 
  and 
  skulls, 
  which 
  proved 
  

   that 
  the 
  form 
  was 
  entitled 
  to 
  a 
  subspecific 
  rank. 
  While 
  the 
  skull, 
  

   according 
  to 
  Herr 
  Schwarz's 
  description 
  given 
  above, 
  does 
  not 
  present 
  

   any 
  very 
  strongly 
  marked 
  distinctive 
  characters, 
  yet 
  the 
  differences 
  

   mentioned, 
  together 
  with 
  the 
  paler 
  coloration 
  of 
  the 
  pelage 
  would 
  

   seem 
  to 
  be 
  sufficient 
  for 
  its 
  recognition 
  as 
  a 
  subspecies.
