  Collected 
  

   August, 
  1905, 
  by 
  L. 
  Egg. 
  Two 
  specimens, 
  both 
  fully 
  

   adult, 
  with 
  basilar 
  suture 
  closed. 
  

  

  The 
  different 
  forms 
  of 
  the 
  jaguarondi 
  seem 
  to 
  be 
  distin- 
  

   guishable 
  by 
  little 
  but 
  size, 
  as 
  their 
  colour 
  varies 
  exceedingly, 
  

   specimens 
  from 
  the 
  same 
  locality, 
  unquestionably 
  conspecific, 
  

   often 
  differing 
  widely 
  in 
  their 
  tone 
  of 
  gi'ey, 
  blackish, 
  or 
  

   rufous. 
  The 
  variation 
  in 
  the 
  development 
  of 
  the 
  protocone 
  

   of 
  the 
  carnassial 
  is 
  also 
  very 
  striking, 
  and 
  is 
  well 
  shown 
  in 
  

   the 
  two 
  specimens 
  of 
  the 
  present 
  form, 
  the 
  male 
  having 
  it 
  

   reduced 
  (as 
  is 
  common 
  in 
  jaguarondis) 
  and 
  the 
  female 
  having 
  

   quite 
  a 
  large 
  one. 
  

  

  The 
  largest 
  jaguarondi 
  is 
  this 
  one 
  from 
  the 
  Peruvian 
  Andes, 
  

   the 
  central 
  one 
  from 
  Venezuela 
  to 
  Argentina 
  is 
  intermediate 
  

   in 
  size, 
  while 
  the 
  Guianan 
  and 
  Eastern 
  Brazilian 
  form, 
  fur 
  

   which 
  the 
  name 
  oi 
  unicolor 
  is 
  available, 
  is 
  the 
  smallest 
  of 
  all.
