Specimen 9. The imperfect middle portion of a skull, ai)i)ar- 

 ently of the tj^pe species. The skull has Ijeen broken across a little

Specimen 10. A 1)adly weathered skull of the same species. 

 The Sfierimen has had the snout broken off behind the canines, 

 anil the mandibles have been almost com[)letely weathered away, 

 l)ut the posterior part is fairly complete, though largeh- unde- 

 veloped and with the temporal arches weathered away. The 

 specimen is of value in showing the structure of the jugal, which 

 is characterised by having a well-marked downward process. This 

 process is much less developed than in Gomphognathus, but 

 relatively more developed than in Cynognathus. It also throws 

 some light on the (juadrate region.
