  Mr. 
  Hollister 
  made 
  this 
  animal 
  a 
  subspecies 
  of 
  L. 
  pygerythra, 
  but 
  

   it 
  would 
  seem 
  that 
  its 
  coloring 
  and 
  the 
  black 
  chin 
  would 
  give 
  it 
  more 
  

   properly 
  a 
  place 
  between 
  L. 
  rubella 
  and 
  L. 
  centralis. 
  The 
  general 
  

   hue 
  of 
  the 
  pelage, 
  especially 
  on 
  the 
  dorsal 
  region, 
  is 
  much 
  too 
  dark 
  

   for 
  L. 
  pygerythra, 
  in 
  fact 
  it 
  is 
  not 
  of 
  the 
  same 
  character, 
  but 
  is 
  much 
  

   nearer 
  the 
  more 
  tawny 
  hue 
  of 
  L. 
  rubella 
  ; 
  and 
  its 
  black 
  hands 
  and 
  feet 
  

   are 
  quite 
  unlike 
  those 
  of 
  L. 
  pygerythra. 
  Its 
  distinctive 
  characters 
  

   prohibit 
  it 
  from 
  being 
  regarded 
  as 
  a 
  subspecies 
  of 
  any 
  described 
  form.
