656 MR. R. BROOM ON ANOMODONT REPTILES 



of the upper surface is unfortunately lost, including both jDOst- 

 orbital arches with the whole of the postorbital bones, practically 

 the whole of the parietal region, and both squamosals. Still, 

 what is preserved shows that it is a strikingly new type, and I 

 have much pleasure in calling it after Dr. Smith Woodward, of 

 the Bi-itish Museum. 



The skull is moderately small, having measvired about 6 inches 

 in length. The snout is long and narrow, the preorbital portion 

 of the skull being nearly as long as the postorbital. The nasal 

 region is imperfect, but there were probably no great bony 

 thickenings. The maxillfe have each a round tusk, the head of 

 which lies under the orbit, and the tusks are relatively farther 

 back from the front of the beak than in most species. 



The frontals are long and moderately narrow. Behind them 

 lies a most remarkably broad preparietal quite unlike that of 

 any other known species. By its sides, are narrow posterior 

 processes of the frontals. The postfrontals lie outside the 

 frontal processes. The postorbitals are lost, but from the con- 

 dition of the posterior parts of the squamosal it is manifest that 

 the temporal region must have been comparatively narrow. 



The following are the principal measurements : — 



Greatest antero-posterior length... about 160mm. 



Greatest breadth perhaps about 110 ,, 



Basallength 145 ,, 



Interorbital width 30 ,, 



Distance between tusks 29 ,, 



DiCYNODON iCTiNOPS, sp. n. (Text-fig. 35.) 



This new species is formed on the nearly perfect skeleton of a 

 small animal found by me about 30 miles from Biesjespoort on 

 the Mui'raysburg Road. While it is quite possible that tiie form 

 is not quite fully grown, it cannot be the young of any known 

 species. 



head is about oj 

 from snout to the tip of the tail about 12| inches. 



The snout is smooth and rounded, without any bony thickening 

 either on the nasals or in the supraorbital regions, except a very 

 slight thickening on the nasal just where it ovei'hangs the 

 nostril. The septomaxillary does not appear to show on the 

 face. The lacrimal and prefrontals are small. In the maxilla? is 

 a small tusk. 



The frontals are large, and a transverse section in the orbital 

 i-egion would show a convex upper surface, while a section of the 

 posterior end would have a concave upper surface. The post- 

 frontals are small, and only a small part appears on the surface. 

 The preparietal is rather small, its anterior end being on the 

 plane of the postorbital arch. The pineal foramen is situated far 

 back. The parietals are small. The postorbitals are very large,
