Same history. 



R. 55. A very similar specimen ; from Sussex. Purchased, 1881. 



36510. The terminal phalangeal of one of the lateral digits of the 

 pes, not improbably belonging to this species ; from Cuck- 

 field. Mantell Collection. Purchased, 1853. 



c. Of Uncertain Position. 

 Iguanodon, sp. 



Slightly larger than /. mantelli. Anterior and middle dorsal 

 vertebrae with moderately tall arches, in which the rib-facet does 

 not reach the level of the platform, and their centra moderately 

 short and somewhat wedge-shaped. The sternal (?) bones are like 

 those of the Euiguanodont group ; the scapula approximates to that 

 of /. mantelli, but is larger in proportion to the other bones, 

 and compared with that species the arches of the anterior dorsal 

 vertebrae appear lower, the centra of the posterior dorsals shorter, 

 the inner trochanter of the femur extending further up and down 

 the shaft, the head of the femur placed more obliquely to the shaft, 

 and the astragalus and apparently the ilium of different contour. 



This form probably indicates a new species. 



Hah. Europe (England). 



R. 33. A considerable portion of the skeleton ; from the Wadhurst 

 Clay (Lower Wealden) of Hollington, near Hastings, 

 Sussex ; found in 1880. These specimens comprise frag- 

 ments of the teeth and mandible, a large series of imper- 

 fect cervical, dorsal, and caudal vertebrae ; the sternal (?) 

 bones (one imperfect), the proximal half of the right scapula, 

 radius, and ulna, a metacarpal fragment of an ilium, the 

 right femur, part of right astragalus, the entire second 

 and third and the distal extremity of the fourth right meta- 

 tarsal, and numerous phalangeals. The fragment of the 

 ilium appears to differ very considerably from that of 

 /. mantdli ; the astragalus also diverges from the corre- 

 sponding fragment (No. II. 130) of that of the latter to a
