C. 9329, C. 9230, C. 9332. Atlas, axis, and (?) third cervical vertebrae, presumably associated and 
perhaps belonging to the same animal as the portions of a skull just noticed. Described 
and figured above (text-fig. 83). These vertebrae are in a nearly perfect state of 
preservation. The epiphyses are not fused with the centrum, though still in sitn. The 
dimensions (in centimetres) of these vertebrae are given below : —
