A tooth from the top of the Karoo beds, above the Indwe coal, 

 is described and figured. It differs from all known types, but in 

 some respects resembles C. Guilielmi (Plein) from the Muschel- 

 kalk, and G. Hislopianus from the Gondwana beds of Nagpur.

Fossils sent to Mr. Seward came from the Molteno beds of the 

 Southern Transvaal. The beds rest unconformably upon rocks 

 said to be of carboniferous age, and have a boulder bed containing 

 fragments of these older rocks at their base. 



At Boschman's Fontein and Maggie's Mine the plants were 

 . found in shales associated with a coal seam. 



At Casey's Township the fossils occur in an outlier resting on 

 quartzites and conglomerate said to be Table Mountain Sand- 

 stone. 



Near Vereeniging the plants came from a quarry near the 

 junction of the Vaal and Klip rivers. 



At Zwart Koppies the plants occur in an outlier resting on 

 granite and schists. 



The Molteno beds (Triassic) are younger than the Karoo beds, 

 which contain abundant reptiles ; the presence of Sigillaria 

 shows that a typical carboniferous plant of the Northern 

 Hemisphere lived into Triassic times in South Africa.
