mentioned under the head of Tapinocephalus in its flattened 

 hasmal and lateral surfaces ; and since those vertebras are 

 associated with lumbars of the type of No. R. 1706 (p. 84) 

 it would appear that the present specimen cannot belong 

 to the same form as the latter. 



Presented by W. G. Atherstone, Esq., M.D., 1872. 



R. 1709 a. An imperfect anterior dorsal vertebra ; from the same 

 (Fig.) locality as the preceding, and apparently associated. 

 Figured by Owen in his ' Catalogue of the Fossil Reptilia 

 of S. Africa,' pi. xi., and referred to Pariasaurus, the 

 locality being incorrectly given as Vers Fontein. This 

 specimen, which has. .been longitudinally bisected in a 

 horizontal plane, has the costal facet partly on the centrum 

 and partly on the arch, and the centrum is more rounded 

 than in the preceding specimen. 



Presented by W. G. Atherstone, Esq., M.D., 1872. 



R. 1709 b. A very imperfect dorsal centrum, showing the rib- facets ; 

 from the same locality, and probably associated with the 

 preceding. 



Presented by W. G. Atherstone, Esq., M.D., 1872. 



R. 1709 c. An imperfect dorsal centrum of the same type; from 

 the same locality. 



Presented by W. G. Atherstone, Esq., M.D., 1872. 



R. 1709 d. Four imperfect caudal vertebras ; from the same locality, 

 and probably associated with the preceding. 



Presented by W. G. Atherstone, Esq., M.D., 1872. 



R. 852. Two imperfect centra of large trunk-vertebras ; from the 

 Karoo system of the Gouph district, near Beaufort West. 

 In their constricted and carinated form these specimens 

 approximate to the later dorsals of the series noticed 

 under the head of Tapinocephalus. 



Purchased from T. Bain, Esq., 1880. 



R. 851. Three associated imperfect dorsal centra of the same type 

 as the preceding ; from the Gouph district. 



Purchased from T. Bain, Esq., 1880. 



47106. The imperfect neural arches and spines of three dorsal 

 vertebras of a large form ; from the Karoo system of the 

 Cape Colony. The height of the neural spine and the
