* Slab of sandstone ; from the Kentish Eag (Hythe beds of 

 {Fig.) Lower Greensand) of Maidstone, Kent. This specimen 

 may be taken as the type of the species, and was dis- 

 covered by W. H. Bensted in 1834 ; it shows the impression 

 of a tooth, a number of trunk and caudal vertebrae, ribs, 

 a sternal (?) bone, and most of the bones of the scapular 

 and pelvic girdles and fore and hind limbs. Noticed in 

 the ' London and Edinburgh Philosophical Magazine/ 

 July 1834, figured by Mantell in his ' Wonders of Geo- 

 logy,' 1st ed. pi. iii. (1844), and by Owen in his ' Creta- 

 ceous Eeptilia ' (Mon. Pal. Soc.) pt. i. pis. xxxiii., xxxiv. 

 (1851). The right humerus is figured by Mantell in the 

 4 Phil. Trans.' 1849, pi. xxxi. fig. 20 ; and two dorsal 

 vertebrae are figured by Owen, op. cit. pis. xxv., xxvi. 



Mantell Collection. Purchased, 1838. 



2160. An imperfect anterior dorsal vertebra ; from Cuckfield. 



(Fig.) Noticed by Owen in the ' Eep. Brit. Assoc' 1841, p. 128, 

 and figured by Mantell in the ' Phil. Trans.' 1849, pi. 

 xxviii. figs. 7 a, 7 b. The arch is very tall, and the rib- 

 facet long. Since this specimen seems to be adult, it is 

 referred to the present species rather than to a young 

 individual of /. bemissartensis . Same history. 



2137. An imperfect later dorsal vertebra; from Cuckfield. The 

 arch is lower, and the rib-facet must have been shorter. 

 This specimen apparently agrees precisely with the first 

 of the four dorsals in apposition on the right side of the 

 top of the type slab. Same history. 



143 C. An imperfect anterior or middle dorsal vertebra, not impro- 

 bably belonging to this species ; from the Isle of Wight. 

 The arch has been crushed down. Fox Collection. 



2124. The centrum and base of the arch of an anterior or middle 

 dorsal vertebra provisionally referred to this species ; from 

 Cuckfield. Mantell Collection. Purchased, 1838. 



37711. Avery similar centrum ; locality unknown. 



Saul Collection. Purchased, 1863. 



28940. A rather larger centrum of similar type : from the Isle of 

 "Wight. Mantell Collection. Purchased, 1853. 



28939. The centrum and base of the arch of a very similar specimen ; 

 from the Islo of Wight. Same history.
