   ment 
  at

  World's 
  Columbian 
  Exposition 
  were 
  presented 
  to 
  the

  These 
  Avere 
  labeled 
  ''Guatemala" 
  without 
  definite 
  

   locality 
  but 
  are 
  believed 
  to 
  be 
  from

  and

  repre- 
  

   sent 
  typical

  Aside 
  from 
  the 
  very 
  dark 
  coloration, 
  the 
  coat 
  

   is 
  long 
  and 
  heavy, 
  indicating 
  that 
  they 
  came 
  from 
  a 
  high 
  elevation 
  in 
  

   the 
  mountains. 
  The 
  skulls 
  indicate 
  close 
  agreement 
  with 
  vellerosus 
  

   in 
  size 
  and 
  general 
  details.
