674 ON ANOMODONT REPTILES FROM SOUTH AFRICA. 



The qiiadra,te and quadrato-jugal ax^e lost from the left side, 

 but preserved in a slightly displaced condition on the right. As 

 in Dicynodon, they are apparently ankylosed, and their displace- 

 ment from the squamosal and paroccipital adds further evidence 

 to observations I have made in Dicynodon, that while the 

 quadrate is fixed to the quadrato-jugal, the quadrato-jugal has a 

 very considerable degree of movement on the squamosal, and 

 thus relatiA^ely to the skull the quadrate is perhaps as freely 

 movable as in the Lizard, in Anomodonts, and also in 

 Cynodonts. 



The palate is similar to that in other Endothiodonts, and does 

 not differ greatly from the Dicynodon type. The periotic 

 processes do not descend to the same degree as in Dicynodon, but 

 are clasped by the basisphenoids in a similar manner, and have 

 each a large foramen ovale for the end of the stapes. Endothiodon 

 differs from Dicynodon in having a large median basisphenoid boss. 



The occipital condyle is flat as in other Endothiodon species. 



The following are the principal measurements of the skull : — 



Greatest antero- posterior lengtli 502 mm. 



Greatest breadth across squamosals .... 400 ,, 



Greatest breadth across jugals 430 ,, 



Breadth across nasals , 180 ,, 



Breadth between nostrils 60 ,, 



Basal leng-th 435 .,
