LXVII. — On some Reptilian Lower Jaics. 

 By D. M. S. Watson, M.Sc. 



The object of this paper is to describe the lower jaws of 

 some fossil reptiles and amphibians of Permian and Triassic 

 age from South Africa, and to discuss briefly the bearing o£ 

 their structure on some morphological questions. 



Deinocephalta, 



The structure of the Deiuocephalian lower jaw has been 

 briefly described by Seeley (1896) and Broom (1910, 1911), 

 but is not completely known. No known specimen shows 

 the splenial or covonoid. 



The outer aspect is very like that of Dinietrodon, and the
