  Passing 
  now 
  to 
  tlie 
  Zovro 
  of 
  Buenos 
  Ayres, 
  an 
  animal 
  

   probably 
  the 
  same 
  as 
  the 
  Agouarachay 
  of 
  Azara^ 
  we 
  find 
  that, 
  

   owing 
  to 
  its 
  liaving 
  been 
  generally, 
  though 
  erroneously, 
  

   known 
  as 
  Canis 
  azarce, 
  no 
  tenable 
  name 
  exists 
  for 
  it. 
  All 
  

   the 
  numerous 
  names 
  put 
  into 
  its 
  synonymy 
  by 
  Burmeister, 
  

   Mivart, 
  and 
  Trouessart 
  are 
  accounted 
  for 
  elsewiiere, 
  and 
  I 
  

   therefore 
  now 
  give 
  it 
  a 
  new 
  name. 
  

  

  As 
  it 
  has, 
  however, 
  been 
  so 
  long 
  connected 
  with 
  Azara's 
  

   name, 
  and 
  the 
  word 
  azanv 
  (being 
  synonymous 
  with 
  brasili- 
  

   emis) 
  now 
  disappears 
  altogether, 
  so 
  that 
  no 
  contusion 
  can 
  

   arise, 
  1 
  propose 
  to 
  apply 
  a 
  term 
  which 
  equally 
  recalls 
  the 
  

   famous 
  Spanish 
  naturalist 
  who 
  first 
  discovered 
  it.

  As 
  shown 
  by 
  Burmeister, 
  this 
  species 
  differs 
  from 
  its 
  

   nearest 
  ally, 
  the 
  " 
  Chilla" 
  of 
  Chili, 
  by 
  its 
  larger 
  size 
  and 
  the 
  

   more 
  broadly 
  expanded 
  frontal 
  region 
  of 
  the 
  skull.
