47169 a. The centrum of a large cervical vertebra ; from the 

 Cornbrash of Stilton. The centrum is elongated, and the 

 specimen seems to indicate a species closely allied to 

 C. plicatus. Sharp Collection. 



47169 b. The centrum of a later immature cervical vertebra ; from 

 Stilton. This specimen is relatively rather shorter than 

 the posterior cervicals No. 36173 (p. 239) of C. plicatus. 



Sharp Collection. 



32719. The centra of three small and immature associated dorsal 

 vertebrae : from the Oxford Clay of Yaches-Noires. The 

 shortness of the centra suggests reference to C. plicatus. 



Tesson Collection. 



27488. A similar specimen; from Yaches-Noires. 



Hastings Collection. Purchased, 1855. 



47169 C. An anterior dorsal vertebra, wanting the greater portion 

 of the neural arch ; from the Cornbrash of Stilton. This 

 specimen closely resembles the anterior dorsal No. 47880 

 (p. 239), referred to C. plicatus. Sharp Collection. 



47169 d. An imperfect later dorsal vertebra of similar type : from 

 Stilton. Sharp Collection. 



47169 e. An imperfect dorsal vertebra of the same general type ; 

 from Stilton. Sharp Collection. 



47169 f. The centrum of an immature anterior caudal vertebra ; 

 from Stilton. Accords very closely with the caudal of 

 C. richardsoni, No. E. 1263 a. Neither the ribs nor 

 chevrons were anchylosed. Sharp Collection. 



47169 g. A rolled caudal centrum of similar type ; from Stilton.

Cimoliosaurus, sp. 



Very imperfectly known. Of the approximate dimensions of 

 C. truncatus, to which it may be very closely allied. 

 Hab. Europe (France and (?) England).

 ferior Oolite (Lower Jurassic) of Harcourt (Eure), Erance. 

 These specimens comprise a middle and a posterior cervical. 

 The dimensions of the former are : — length 0,068
