  Genl.

  Like 
  L. 
  preussi

  darker. 
  

  

  Color. 
  Hairs 
  on 
  upper 
  parts 
  blackish 
  slate 
  at 
  their 
  bases 
  for 
  over 
  

   half 
  their 
  length, 
  then 
  ringed 
  with 
  dull 
  bufTy 
  and 
  tipped 
  broadly 
  with 
  

   black. 
  Tail 
  at 
  root 
  chestnut. 
  Young 
  female. 
  No 
  dimensions 
  given. 
  

  

  It 
  can 
  hardy 
  be 
  considered 
  that 
  the 
  subspecific 
  distinctness 
  of 
  a 
  

   Fernando 
  Po 
  race, 
  has 
  as 
  yet 
  been 
  well 
  established, 
  the 
  material, 
  one 
  

   immature 
  female, 
  being 
  hardly 
  sufficient. 
  An 
  examination 
  of 
  additional 
  

   adult 
  examples 
  is 
  desirable.
