Temporal Fossa. 



It is (]nitc certain from the condition of tlie postorbital 

 arcade, wliicli is perfectly preserved on each side, tliat tliere 

 is only one lateral temporal fossa. "Whether this Mas not 

 closed Idow by an arch, as in AVilliston's Varanoftawus 

 brevirostris , is not by any means certain. 



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

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

 p{;storbital bar, and on the same side the bone \vhich covers 

 the outer side of tlic quadrate (probal)ly 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 TheropJevra or Opliiacodcn than of Varano- 

 suarus brevirostris as fiirurcd bv \\ illistoh.
