  — 
  The 
  trunk 
  and 
  limbs 
  agree 
  with 
  those 
  of 
  

   its 
  congener, 
  but 
  the 
  skull 
  is 
  very 
  different, 
  owing 
  to 
  the

  more 
  extensive 
  dermo-ossification 
  of 
  the 
  post-orbital 
  

   region, 
  which 
  forms 
  a 
  complete 
  roof 
  over 
  the 
  prootic, 
  

   only 
  the 
  posterior 
  portion 
  of 
  the 
  latter 
  being 
  visible 
  

   from 
  above. 
  This 
  roof, 
  which 
  completely 
  closes 
  the 
  

   orbit 
  behind; 
  is 
  formed 
  by 
  the 
  fronto-parietal 
  and 
  the 
  

   squamosal; 
  the 
  latter 
  bone 
  has 
  a 
  convex 
  posterior 
  

   border, 
  separated 
  from 
  the 
  likewise 
  curved 
  posterior 
  

   border 
  of 
  the 
  fronto-parietal 
  plate 
  by 
  a 
  notch, 
  the 
  

   angle 
  of 
  which 
  corresponds 
  to 
  the 
  suture 
  between 
  the 
  

   two 
  bones.
