  The 
  type 
  of 
  this 
  form 
  died 
  in 
  the 
  Menagerie 
  of 
  the 
  Jardin 
  des 
  

   Plantes, 
  and 
  was 
  described 
  by 
  Pucheran 
  (1. 
  c). 
  In 
  having 
  the 
  three 
  

   stripes 
  on 
  the 
  head 
  it 
  is 
  nearer 
  trivirgatus 
  and 
  rufipes, 
  than 
  vocif- 
  

   erans. 
  It 
  is 
  a 
  plain 
  little 
  animal, 
  a 
  dull 
  grayish 
  brown 
  constituting 
  

   the 
  general 
  color 
  of 
  its 
  coat. 
  The 
  under 
  parts 
  were 
  probably 
  a 
  deeper 
  

   yellow, 
  as 
  the 
  hair 
  is 
  faded, 
  not 
  only 
  beneath 
  but 
  over 
  the 
  body 
  

   generally, 
  and 
  originally 
  it 
  was 
  probably 
  considerably 
  darker. 
  The 
  

   golden 
  dorsal 
  line, 
  broadest 
  on 
  the 
  lower 
  part 
  of 
  the 
  back, 
  distinguishes 
  

   this 
  form 
  from 
  rufipes 
  and 
  trivirgatus, 
  which 
  have 
  this 
  part 
  reddish 
  

   and 
  chestnut 
  respectively. 
  The 
  continuation 
  of 
  the 
  lateral 
  stripes 
  to 
  

   the 
  throat 
  where 
  they 
  meet, 
  also 
  distinguishes 
  this 
  species 
  from 
  all 
  

   others. 
  The 
  stripes 
  from 
  mouth 
  across 
  the 
  throat, 
  while 
  of 
  the 
  same 
  

   color 
  as 
  the 
  lateral 
  ones 
  on 
  the 
  head, 
  are 
  fainter.
