  This 
  striking 
  jackal-like 
  dog, 
  by 
  its 
  heavy 
  dentition 
  and 
  

   especially 
  its 
  large 
  carnassial, 
  migiit 
  have 
  been 
  thought 
  to 
  

   belong 
  to 
  the 
  cu/pceus 
  group, 
  but 
  the 
  highly 
  characteristic 
  

   external 
  markings, 
  the 
  blafdc 
  chin, 
  black 
  thigh-patch, 
  and 
  

   brownish 
  (instead 
  of 
  reddish) 
  rump 
  and 
  hams 
  show 
  conclu- 
  

   sively 
  that 
  it 
  is 
  more 
  allied 
  to 
  Azara's 
  fox, 
  the 
  Chilla, 
  and 
  

   their 
  allies. 
  It 
  is, 
  however, 
  readily 
  distinguished 
  from 
  any 
  

   of 
  them 
  by 
  its 
  coarse 
  hair, 
  duller 
  colour, 
  and 
  large 
  teeth.
