  rostral 
  portion 
  of 
  skull 
  are 
  relatively 
  greater, 
  this 
  being 
  cor- 
  

   related 
  with 
  the 
  greater

   num.

   greater,

  a 
  triangular 
  patch 
  on 
  the 
  

   nape, 
  bifurcates 
  well 
  forward, 
  and 
  extends 
  backward 
  as 
  two 
  narrow 
  

   white 
  stripes 
  which 
  are 
  continued 
  on 
  to 
  the 
  sides 
  of 
  the 
  tail 
  and 
  meet 
  

   about 
  the 
  middle 
  of 
  its 
  upper 
  surface. 
  The 
  rest 
  of 
  the 
  caudal 
  hair
