  Skull. 
  

  

  The 
  back 
  of 
  the 
  skull 
  is 
  quite 
  well 
  preserved, 
  ami, 
  despite 
  

   the 
  presence 
  of 
  many 
  cracks, 
  it 
  is 
  possible 
  to 
  make 
  out 
  the 
  

   main 
  lines 
  of 
  its 
  structure 
  with 
  absolute 
  certainty.

  The 
  parietala 
  extend 
  out, 
  in 
  the 
  postorbital 
  region, 
  to 
  tlie 
  

   edge 
  of 
  the 
  flat 
  dorsal 
  surface 
  ; 
  in 
  front 
  they 
  meet 
  the 
  

   frontals 
  ; 
  just 
  behind 
  the 
  orbits 
  their 
  outer 
  borders 
  have 
  a 
  

   square 
  step, 
  by 
  which 
  they 
  articulate 
  with 
  the 
  postfrontals; 
  

   posteriorly 
  their 
  borders 
  are 
  turned 
  down 
  and 
  covered 
  by 
  

   the 
  interparietal 
  and 
  the 
  tabulares 
  ; 
  at 
  the 
  postero-lateral 
  

   corner 
  they 
  articulate 
  by 
  suture 
  with 
  the 
  supratemporal 
  and 
  

   squamosal, 
  and 
  the 
  rest 
  of 
  the 
  lateral 
  border 
  overlies 
  the 
  

   postorbital.
