The caudal vertebra? have slightly concave articular surfaces, which are 

 not bounded by groove or ridge. The neural arches have flat sides; and there 

 is no longitudinal ridge above the diapophyses. The neural spines are ele- 

 vated ; the margins of those of the adjacent vertebrae close together. The 

 diapophysis is very short and wide, terminating in a large oval concavity for 

 the pleurapophyses. Each limb of the chevron-bone is attached to an articu- 

 lar surface on the lower posterior face of (he vertebra at the extremity of a 

 strong inferior ridge. These inferior ridges are rather close together, and 

 distinguish the vertebrae from those of Cimoliasaurus magnus, where they are 

 wanting. They are absent on the anterior seven of the caudal series. The 

 diapophysis is nearer the anterior than the posterior face of the vertebra. 

 The venous foramen is single and median on all but the last six caudals.

Heads of fourteen ribs are preserved, and a great number of shafts. 

 The heads are simple, with elongate-oval articular face. They are oblique 

 in the narrow direction, and frequently in their length also ; the margins are 

 somewhat everted. The extremities of the diapophyses of the larger dorsal 

 vertebrae are transverse, some flattened, the others more oval: the more ante-
