MR. R. BROOM OX ANOMODONT REPTILES 



The septomaxilla is nob satisfactorily preserved, but is relatively- 

 small. 



The maxilla is a ver}^ remarkable bone, quite unlike that in 

 any other known Dicynodont. The bone of the left side has lost 

 the subnasal portion, but is otherwise nearly complete, and it is 

 so remarkably shallow that one would fancy the palatal half had 

 been removed ; yet if part of the bone has been removed, it must 

 have been done dui-ing the animal's lifetime. There is no tra,ce 

 of a tusk, yet there are the remains of the socket of a large tusk.

Skull of Sainia peavoti Broom. 



A not improbable explanation of the peculiai-ity is that the 

 animal is aged and has lost its tusks, and that in consequence 

 the palatal portions of the bone have become absorbed, as is seen 

 in aged human and other mammalian jaws. 



The prefrontal is a relatively small trianguar bone which has 

 a small and not very prominent boss above the front of the orbit. 



The lacrimal is small.
