The unworn teeth of the type specimen 3 have compressed crowns,

 pt. v. p. 33. BecTcles Collection. Purchased, 1876. 



48233. A number of similar specimens, apparently belonging to the 

 same form ; from Durdlestone Bay. These specimens in- 

 clude the types of /Saurittus obtusus. Same history. 



48385. Slab showing fragment of mandible, a limb-bone, and dermal 

 scutes ; from Durdlestone Bay. Same history.
