62 ANOMODONTIA. 



R. 1704 h. Two small and imperfect trunk vertebrae ; from the 

 Cape Colony. The centra are much compressed. 



No history. 



K. 1704 i. Three imperfect and somewhat larger vertebral centra ; 

 from the Cape Colony. These specimens are of a broad 

 and uncompressed type. No history. 



Family uncertain. 



**PLATYPODOSAURUS, Owen \ 



Pounded upon portions of the axial and appendicular skeleton, 

 which do not include the skull, but which appear to be decidedly 

 Pieynodont. The chief distinctive feature of these specimens is the 

 great development of the inferior portion of the delto- pectoral crest 

 of the humerus, which descends lower than in Dicynodon and forms 

 a distinct projection; and also the presence of a smaller process on 

 the opposite or postaxiai border. Scapula approximating to that of 

 Ptychosiagum. 



Prom their general Dicynodont character it would appear pro- 

 bable that these specimens are referable either to Udenodon or to 

 Endothiodon. 



**Platypodosaurus robustus, Owen 2 . 



The type and only described species ; of large size. 

 Hah. South Africa. 



50121. Part of the vertebral column, the right humerus, and the 

 {Fig.) imperfect pelvis ; from the Karoo system 3 of Catelomds, 

 Claremont. These, with the undermentioned associated 

 specimens, are the types. Three of the vertebras and the 

 humerus are figured by Owen in the ' Quart. Journ. Geol. 

 Soc' vol. xxxvi. pi. xvi. figs. 1-3, 7, the figure of the 

 humerus being reversed. Three of the vertebras have been 

 longitudinally bisected, and show the great depth of the 

 terminal cups. In the figure of the humerus there does 

 not appear to be any justification for the prominent angle 

 at the upper extremity of the delto-pectoral crest. When 

 entire the ilium would appear to be of the general type of 

 that of Dicynodon. Presented by E. J. Dunn, Esq., 1879.

3 There is no evidence to show whether these specimens are from the Beau- 

 fort or Stormberg beds.
