N. B. When Fig. 2 was drawn, the specimen was still partly embedded 

 in an extremely hard concretionary matrix and the thin ridge of bone which 

 connects the successive transverse processes was overlooked and is not 

 shown ; the pits at the base of the transverse processes should have been indi- 

 cated as foramina.
