  Temporal 
  Fossa. 
  

  

  It 
  is 
  quite 
  certain 
  from 
  the 
  condition 
  of 
  the 
  postorbital 
  

   arcade, 
  which 
  is 
  perfectly 
  preserved 
  on 
  each 
  side, 
  that 
  there 
  

   is 
  only 
  one 
  lateral 
  temporal 
  fossa. 
  Whether 
  this 
  Avas 
  not 
  

   closed 
  below 
  by 
  an 
  arch, 
  as 
  in 
  Williston's 
  Varanosaiirus 
  

   brevirostris, 
  is 
  not 
  by 
  any 
  means 
  certain. 
  

  

  On 
  the 
  right 
  side 
  the 
  jugal 
  is 
  continued 
  back 
  as 
  a 
  broad 
  

   bone 
  on 
  the 
  side 
  of 
  the 
  skull 
  for 
  a 
  centimetre 
  behind 
  the 
  

   postorbital 
  bar, 
  and 
  on 
  the 
  same 
  side 
  the 
  bone 
  which 
  covers 
  

   the 
  outer 
  side 
  of 
  the 
  quadrate 
  (probably 
  the 
  quadrato-jugal) 
  

   is 
  continued 
  forwards 
  with 
  a 
  horizontal 
  lower 
  border, 
  as 
  if 
  

   to 
  meet 
  the 
  jugal. 
  The 
  condition 
  of 
  this 
  region 
  is 
  much 
  

   more 
  like 
  that 
  of 
  TheropJeura 
  or 
  Opliiacodtm 
  than 
  of 
  Varano- 
  

   saunis 
  brevirostris 
  as 
  figured 
  by 
  Williston,

  Of

  little 
  can 
  be

   There 
  is 
  a 
  splenial 
  entering 
  the 
  symphysis, 
  and 
  the

  is 
  

   very
