its under surface from front to back and convex from side to 

 side. 



Nos. 332, 333, 334, 335 are p-obably cervical vertebrge ; 

 but their condition of preservation contributes nothing to 

 knowledge of the type, and I believe they pertain to another 

 species. 



Dorsal Verteh'ce. 



The dorsal vertebrse have the centrum only preserved, 

 though in the specimen numbered 336 the base of the neural 

 arch is seen. These vertebrje, owing to the lateral com- 

 pression of the centrum and the attachment of the neural arch 

 along the whole length of the centrum, have a Teleosauroid 

 aspect ; they measure 2yV inches in length. The measure- 

 ment on the neural canal exceeded that on the ventral border, 

 showing that the back of the animal was arched upward in 

 the antero-posterior direction. The articular ends are laterally 

 compressed, being higher than wide, vertically ovate, 2*2 inches 

 high by 1'7 broad, flattened but slightly concave. The 

 transverse measurement in the middle of the centrum is about 

 ■Yjj inch. The base is markedly concave from front to back 

 and notably convex from side to side. There is only a slight 

 indication of the transverse widening of the neural arch. This 

 vertebra apparently is figured in Cat. Foss. E-ept. Brit. Mus. 

 pt. iv. p. 249, 1890 *. 



Sacral Vertebrce. (Fig. 2.) 



The specimen 346 (fig. 2) I regard as referable to Masso- 

 sjjondylus carinatus. It was referred to Pachyspondylus Orpeni

* The genus there rests partly upon teeth from India named Masso- 

 spondylus Hislopi, from Maleri Gondwana beds, and the 3fussosj}ondylns (?) 

 Mawesi, from the Lameta beds. I am not aware that any teeth from 

 South Africa of the type of Massospondylus have been found. The teeth 

 of HJwpalodon are not unlike those attributed to Massospondylus Hislopi. 

 The Indian bones of Anomodonts hitherto known, however, are from the 

 Panchet rocks.
