NEW CARNIVOROUS THERAPSIDS.

divides into a pair of crests which curve round behind the large 

 temporal fossae to meet the squamosals. 



The squamosal is a large bone which forms much of the 

 posterior surface of the skull. It passes well downwards, and 

 covers most of the relatively small quadrate. Internally it meets 

 the parietal above, and is closely articulated to the tabulare. 



The tabulare is a moderate-sized element, but its lower and 

 outer portions are not preserved. It articulates with the parietal 

 above and the interparietal internally, and overlaps the squamosal 

 externally. 



The interparietal is a small median element. 



As Watson has' already described the palate, it will be un- 

 necessary to say anything further about it. 



The genus Scymnosaurus was founded on a large snout in the 

 South African Museum which was made the type of S. ferox. 

 Some years later, a much smaller snout from Natal was named 

 S. warreni. In both these species the dental formula is i°, c\ m 6 . 

 In the new species the formula is i 3 ,c l ,m 3 , and though in the 

 absence of the snout of S. watsoni, and knowing little except the 

 snouts of the others, there is doubt about all belonging to the 

 same genus, it seems safest at present to refer the new species to 

 Scymnosaurus, to which in any case it is certainly closely allied. 



The type is numbered R. 4100 in the British Museum Register. 



SCYMNOGNATHUS PARVUS, Sp. 11. (Text-fig. 7.) 



The type of this new species is a specimen found by Mr. D. M. 

 S. Watson at Kuilspoort, Beaufort West district, and probably 

 from the upper part of the Endothiodon zone.
