47338. Fragment of rock showing in a split surface a portion of the 

 {Fig.) left mandibular ramus, with teeth ; from the Karoo system 



on the Bushman's river, below Graham's Town, Albany.

Anthodon (?), sp. 



The following specimen, which presents no characters by which 

 it can be distinguished from Anthodon, indicates a much smaller 

 reptile than adult individuals of the type. Its higher geological 

 horizon tends to confirm its specific distinctness from A. serrarius. 



Hab. South Africa. 



R. 502. Cast of a fragment of rock showing one lateral aspect of an 

 imperfect tooth. The original was obtained from the 

 Wood-bed stage of the Uitenhage system on the Sunday's 

 river, Uitenhage, and is preserved in the Museum of the 

 Geological Society. It is noticed in the ' Quart. Journ. 

 Geol. Soc' vol. xxiii. p. 164.

Genus PARIASAURUS, Owen l . 

 The type genus. Cranium very broad and much depressed, with 

 deeply descending postorbital flanges. Marginal teeth with mode- 

 rately tall, swollen, and narrow crowns, with a few deeply marked 

 flutings descending from the cutting-edge ; roots moderately long 

 and nearly as wide as the crowns; numerous conical teeth on 

 palate. Vertebrae with comparatively short centra, which apparently 

 have flattened terminal faces ; the dorsal ribs articulating with a 

 pedunculate rib-facet on the centrum, and a long transverse process 

 on the arch ; intercentra in dorsal and caudal regions. When 

 known, some 29 vertebrae, of which 18 are presacral. Ischia much 

 produced backwardly. It is suggested that there may have been 

 a dermal armour.
