Though for many years reptilian bones liave been known 

 to occur in the Karroo beds of Xatal, until a few months 

 ago nothing definite has been known concerning them. Mr- 

 William Anderson, lately government geologist of Xatal, 

 recently submitted to me a small collection of reptilian 

 remains for examination. Though most of the specimens 

 were extremely fragmentary, those that could be identified 

 were all Anomodonts, and for the most part belonged to the 

 genus Lyst rosaurus. A second collection has just been 

 sent me for examination by Dr. Warren, and comprises speci- 

 mens belonging to the Grovernment Museum, Pietermaritzburg. 

 Though the collection is small, and many of the specimens 

 very imperfect, almost all the fragments can be identified, 

 and the collection proves to be of considerable interest. 

 Most of the specimens belong to a large Dicy no don, which 

 proves to be a neAv species, and there is also a specimen of a 

 new species of Therocephalian. These two new species I 

 have much pleasure in describing. Three Natal species are 

 now known, and though they belong to Avell-known genera 

 they are all very distinct from the species known in Cape 

 Colony. This is a little reniarkable, considering that the forms 

 from the Western Karroo beds are identical with those from 

 similar horizons in the Eastern Province. Very likely the
