the ' Phil. Trans.' 1841, pi. ix. fig. 7, and 1850, pi. xxiii. 

 figs. 11 a, 115, and pi. xxvi., as a premedian of Peloro- 

 saurus, and by Owen in his ' Wealden and Purbeck 

 Reptilia,' suppl. ii. pi. v. figs. 3, 4, under the same 

 name ; its close resemblance to the postmedian caudal of 

 C, oxoniensis figured by Philipps, op. cit. p. 261, fig. 91, 

 is noticed on page 266 of the work quoted ; both showing 

 the absence of distinct postzygapophyses.

 caudal vertebra; from Cuckfield.

 Cuckfield. Same history. 



27500. Three associated bones, comprising the chevron of an anterior 

 caudal vertebra, a posterior caudal vertebra, and a portion 

 of the pubis and ischium ; from Brook. These specimens 

 resemble No. 36559 in their white colour, and may not 

 improbably have belonged to the same individual. In the 

 posterior ca.udal the prezygapophyses are very long, and 

 project far in advance of the centrum. 



Hastings Collection. 



R. 206. A series of associated bones, probably belonging to this 

 species, and not improbably to the same individual as 

 No. 36559 ; from Brook. They comprise portions of the 

 two bones of the second segment of a limb, five meta- 

 podials, and four phalangeals. Fox Collection.
