  487 
  

  

  Rio 
  Atrato 
  in 
  the 
  Department 
  of 
  Choc6 
  and 
  north 
  of 
  the 
  Rfo 
  Ranch- 
  

   erla, 
  m 
  La 
  Guajira. 
  The 
  subspecies 
  may 
  range 
  into 
  the 
  Lake 
  

   Maracaibo 
  basin 
  in 
  Venezuela 
  but 
  external 
  characters 
  of 
  the 
  tapir 
  

   there 
  are 
  imknown, 
  (See 
  map, 
  fig. 
  62). 
  H. 
  H. 
  Smith 
  (in 
  Allen, 
  

   supra 
  cit.) 
  stated 
  that 
  on 
  the 
  western 
  slope 
  of 
  the 
  Santa 
  Marta 
  

   region, 
  Magdalena, 
  "the 
  tapir 
  is 
  common 
  from 
  sea-coast 
  to 
  6,000 
  

   feet, 
  and 
  probably 
  higher 
  as 
  I 
  have 
  seen 
  tapir 
  tracks 
  at 
  nearly 
  8,000 
  

   feet." 
  I 
  saw 
  no 
  signs 
  of 
  tapir 
  above 
  700 
  meters 
  on 
  the 
  southern 
  

   and 
  eastern 
  slopes 
  of 
  the 
  Sierra 
  Nevada 
  de 
  Santa 
  Marta. 
  In 
  the 
  

   absence 
  of 
  reliable 
  records 
  proving 
  otherwise, 
  the 
  altitudinal 
  range 
  

   of 
  the 
  species 
  has 
  been 
  determined 
  as 
  sea 
  level 
  to 
  not 
  over 
  1,200 
  

   meters 
  above. 
  The 
  tapir 
  is 
  certainly 
  extinct 
  now 
  in 
  the 
  Department 
  

   of 
  Atldntico 
  and 
  is 
  vanishing 
  from 
  C6rdoba. 
  

  

  Characters. 
  — 
  Distinctly 
  paler 
  throughout 
  than 
  Guianan 
  representa- 
  

   tives 
  of 
  terrestris; 
  slightly 
  darker, 
  less 
  gray 
  than 
  the 
  Mato 
  Grosso- 
  

   Chaco 
  tapir 
  at 
  the 
  opposite 
  extreme 
  of 
  the 
  range 
  of 
  the 
  species.
