R. 1706. A nearly entire lumbar vertebra ; from the same locality

as the type, and from the nature of its mineralogical con- 

 dition and peculiar colour, as well as from its somewhat 

 rolled condition, doubtless belonging to the same indi- 

 vidual. This specimen (woodcut, fig. 18) is noticed by 

 Owen in his ' Catalogue,' p. 10, no. 19, as a late dorsal or 

 lumbar of Pariasaurus. Facets for a free rib, or trans- 

 verse process, at the junction of the arch with the cen- 

 trum, show the presence of autogenous lateral elements 

 in the hinder part of the presacral series. The centrum 

 has a flattened hsernal surface, with the lateral surfaces 

 also flattened and having an angulated junction with the 

 former. The width of the centrum is 0,138 (5'5 inches).

 specimen, in all probability referable to the same indi- 

 vidual. Figured by Seeley in the • Phil. Trans.' for 1889,
