All the fossil crocodiles havethis in the posterior part of the column. It further corresponds with the Plesiosaurian verte-brae in having the ribs articulated by a single tubercle, tothe end of the transverse process, the articulating face ofwhich is oblong horizontally; this structure is observedin the crocodiles in the three last vertebrae only. Thespecimen under examination, however, differs from anyspecies of the Plesiosaurus hitherto described, both in.
