  marking 
  on 
  

   muzzle 
  extending 
  back 
  on 
  to 
  the 
  head,

  General 
  

   colour 
  of 
  back 
  bright 
  yellowish 
  red, 
  speckled 
  with 
  black, 
  

   the 
  yellow 
  tint 
  gradually 
  passing 
  into 
  the 
  pinkish 
  brown 
  of 
  

   the 
  flanks. 
  Back 
  of 
  head 
  slightly 
  darker 
  than 
  rest 
  of 
  dorsal 
  

   surface 
  and 
  speckled 
  with 
  bright 
  yellow 
  and

  the

  tips 
  and 
  

   the 
  black 
  to 
  dark 
  roots 
  of 
  the
