28659. The proximal portion of a rib ; from Brook. Apparently 

 (Fig.) the, one figured by Owen in his * Wealden and Purbeck 

 Eeptilia/ pt. ii. pi. ii. fig. 9. Appears to have been asso- 

 ciated with the vertebrae of the same collection. 



Mantell Collection. Purchased, 1853.

 with the preceding. Same 



28659 b. A similar and apparently associated specimen. 



Same history.

 of Wight. Presented by E. Backhouse, Esq., 1866. 



28628. Anterior portion of the sacrum ; from the Isle of Wight. 

 This specimen appears to have been associated with the 

 above-mentioned posterior dorsal or lumbar vertebrae of 

 the Mantell Collection. Three anchylosed vertebrae remain, 

 of which the first is somewhat flattened inferiorly, while 

 the others are laterally compressed, although to a some-

R. 148. The centrum and base of the arch of a sacral vertebra, 

 perhaps belonging to this form ; from the Isle of Wight. 

 This specimen belongs to a different part of the sacrum 

 from the preceding. Fox Collection. 



28633. An anterior caudal vertebra, wanting the extremity of the 

 (Fig.) neural spine ; from Brook. Figured by Owen, op. cit. 

 pi. xi., as Pelorosaurus, and erroneously stated to be 

 from Sussex. The length of the centrum superiorly is 

 0,102, its vertical diameter 0,225, and the transverse 

 0,198. These dimensions are slightly larger than those of 

 the caudal vertebra (fig. 43) described and figured by
