R. 1283. Cast of a smaller middle (?) cervical vertebra. The

canal to the summit of the spine being 0,102 (4 inches). 

 The relatively great height of the neural spine is in

 whole of the sutures are obliterated.

47426. The centrum of an immature dorsal vertebra probably 

 referable to this species ; from the Oxford Clay of 

 Whittlesea, near Peterborough. This specimen is relatively 

 shorter than in the dorsals of C. plicatus, in which respect 

 it agrees with those associated with No. R. 1263.
