142 DINOSAUKIA. 



Generically undetermine I Specimens, some of which may belong to 

 the present family. 



R. 96. Part of the centrum and one rib of a cervical vertebra in a 

 decomposed condition ; from the Wealden of Brixton, Isle 

 of Wight. The total length is nearly 0,700 (24 inches). 

 In its extremely elongated form this specimen approxi- 

 mates to the cervical vertebrae of Morosaurus, and may 

 perhaps therefore be referable to Cetiosaurus brevis. 



Fox Collection. Purchased, 1882. 



46780. The anterior portion of an apparently similar cervical 

 {Fig.) vertebra ; from the Wealden of the Isle of Wight. This 

 specimen has been longitudinalty cut and polished, and 

 is figured by Owen in his 'Wealden and Purbeck Reptilia ' 

 (Mon. Pal. Soc), suppl. ii. pi. v., as Chondrosteosaurus 

 gigns, of which it is one of the types. Purchased, 1875. 



2239. The centrum and part of the arch of a middle or posterior 

 {Fig.) dorsal vertebra ; from the Wealden of Cuckfield, Sussex. 

 Figured by Mantell in his ' Geology of the South-east of 

 England,' pi. ii. fig. 5, and noticed by Owen in the 'Rep. 

 Brit. Assoc' for 1841, p. 124, and figured by him in his 

 ' Wealden and Purbeck Reptilia,' pt. ii. pi. x., as the 

 quadrate (tympanic) of Iguanodon. Described by Seeley 

 in the ' Ann. Mag. Nat. Hist.' ser. 4, vol. v. pp. 281-282, 

 as one of the types of Ornithopsis huVcei. Figured by 

 Owen in his ' Mesozoic Reptilia' (Mon. Pal. Soc), pt. ii. 

 pi. vii., as Bothriospondylus elongaius, of which species it 

 is the type ; and noticed by Hulke in the ' Quart. Journ. 

 Geol. Soc' vol. xxxviii. p. 375. In the latter notice it is 

 proposed that this specimen should be regarded as the 

 type of Ornithopsis hullcti. The centrum is much narrower 

 and more rounded inferiorly than in the posterior dorsal 

 vertebrae of that species, and the specimen may perhaps 

 have belonged either to Cetiosaurus brevis or Titanosaurus, 

 or to the same form as the undermentioned casts. 



Mantell Collection. Purchased, 1838. 



28701. Cast of an associated left humerus, radius, and ulna. The 

 originals were obtained from the Wealden of the Isle of 

 Wight, and arc in the Collection of Mr. S. H. Bcckles.
