the same suborder as the Dicunodo)itid<i'. Seeley on the other 

 hand would place the Endothiodonts with the Theriodouts rather 

 than with the Dicynodonts. 



Within the last two years I have been fortunate in discovering 

 the greater part of a skull of a large Endothiodoiit — })robably 

 Endutluodon hathystoma^ two fairly complete skulls belonging to 

 two species of a new genus, and a small skull of a second genus. 

 With one of the small skulls I found the greater part of the 

 anterior half of the skeleton. This additional evitience i)roves 

 that the Endothiodonts are exceedingly closely allied to the 

 Dicynodonts. In fact, it is doubtful if there is any character in 

 the skull apart from the presence of small teeth on the maxillaries 

 and dentaries by which they can be distinguished from the true 

 Dicynodonts. 



PRODICYNODOX PEAR8T0NEXSIS, gen. nov. et. S^). nov. 



The type of this new genus and species is unfortunately in a 

 very imperfect condition. It is the anterior half of a small skull 

 broken across through the orbits and very badly weathered. On 

 hasty examination it would appear to be the skull of a small 

 Dicynodon^ and such I considered it to be for some months after 

 I found it. It was only on examining it minutely with a view to 

 determining the species that I discovered behind the large canine 

 a number of small pointed teeth both in the upper and lower 

 jaws. Had the specimen not been badly weathered these teeth 

 would not have been seen, and the specimen would undoubtedly 

 have been referred to as a species of D/cyiiodon, with which it 

 agrees in other respects most closely. 



Owing to the very weathe'-ed condition of the skull, it is 

 impossible to give a very satisfactory description of the bones. The 

 premaxillary is more developed than is usual in Dicynodon, and 

 is relatively broader and flatter. It extends on the upper surface 

 of the skull backwards between the nasals and the prefrontals, 

 and articulates with the frontals. 



The nasals are comparatively small, and are widely separated 

 from each other by the premaxillaries. 



Immediately behind the nasal is the prefrontal, a bone about 

 the same size as the nasal. 



The frontals are long and narrow, but are considerably broader
