TELE0SAURIDJ3. 109 



A. Mystriosaurine Group. 

 The orbits placed more or less laterally ; the posterior nares elon- 

 gated and ovate, the middle line of the cranium more or less convex, 

 and the supratemporal fossae generally not excessively large. 



Steneosaurus heberti, Morel de Glasville ' (fig. 16), from the Lower 

 Oxfordian of Normandy, seems to be the latest representative of the 

 group, but in its large supratemporal fossse approximates to the next 

 group. 



Fig. 16.

 of Normandy, About T V . The bones on the right side of the rostrum are 

 imperfect ; there should have been a line connecting the apex of the frontals 

 with the suture dividing the maxillae ; the preorbital vacuity is not shown.
