R. 604 a. An imperfect anterior dorsal vertebra: from the Wad- 

 hurst Clay (Lower Wealden), near Hastings, Sussex. This 

 specimen is strongly opisthoccelous, which indicates that 

 its position is earlier in the series than the three vertebraa 

 from Battle figured by Owen in his ' Wealden and Purbeck 

 Eeptilia/ pt. ii. pi. xix. Probably associated with the 

 teeth No. R. 604. Dawson Collection.
