666 MR. R. BROOM ON ANOMODONT REPTILES 



In fact, the top of the skull differs so greatly from that of 

 typical Dicynodons, that I feel justified in making the specimen 

 the type of a new genus, Pcdemydops. 



The skvill is flat aiKl broad. The snout is very short. Thei'e 

 are no indications of any thickenings of the nasal bones. The 

 maxilla is short and has a well-developed round tusk. The 

 sutures of the snout elements cannot with certainty be made out. 



The frontals are moderately broad, and on the back part of 

 each is a long deep, probabl}^ glandular pit. The postfrontals are 

 large, and form a considerable part of the orbital margin. The 

 postorbitals are very large, and form the whole of the inner wall 

 of the temporal fossa. 



The preparietal is relatively small and narrow. The pineal 

 foramen is small, and lies much behind the plane of the post- 

 oi'bital arches. The parietals are large. 



The following are the principal measurements of the skull : — 



Grreatest antero-posterior length 75 mm. 



Greatest width 67 ,, 



Interorbital width - 16 ,, 



Intertemporal width 20 ,, 



Emydopsis trigoniceps (Broom), gen. n. (Text-fig. 41 A.) 



In 1904 I described a small Anomodont skull as a species of 

 Oudenodon and called it Oudenodoit trigonicej)s. With the much

greater knowledge which ,we now have it became pretty manifest 

 that it could not be a species of Oudenodon, or rather of 

 Dicynodon, the parietal region being quite different from the 

 Dicynodon type.* The specimen is now in the Albany Museum, 

 and Mr. J. Hewitt, the Curator, kindly sent it to me on loan for 

 further examination. I discovered on breaking into the maxilla 

 that there are three or four slender molar teeth. These are long'
