13. On the Dinosaurs of the Stormberg, South Africa. By E. 

 BROOM,' M.D., D.Sc., C.M.Z.S. 



(Plates XIV.-XVII.) 



THOUGH the first South African Dinosaurs were discovered nearly 

 sixty years ago, only a very few forms have hitherto been described, 

 and these from very fragmentary remains. 



MASSOSPONDYLUS CABINATUS, Owen. 



In 1853 Mr. J. M. Orpen, Government Surveyor, discovered on 

 the farm Beaucherf, Harrismith, a series of fairly large bones, and 

 on the Harrismith commonage some smaller bones. These he 

 forwarded to his father, the Eev. C. E. H. Orpen, of Colesberg, who 

 transmitted them to Professor 0\ven. Owen apparently believed 

 that all the bones came from one spot, and regarded them as 

 belonging to these different genera and species which he named 

 Massospondylus carinatus, Pachyspondylus Orpenii, and Leptospon- 

 dylus capensis. No figures were given by Owen, but in 1895 Seeley 

 redescribed and figured the principal remains, and regarded all as 

 probably belonging to one species. Huene has recently very fully 

 described and figured all the specimens, and agrees with Seeley that 

 all belong to one species, but recognises a larger and a smaller 

 individual. Mr. J. M. Orpen has recently given me particulars of 

 the finds, and it is quite evident that there are two individuals 

 represented, and probably only two. Unfortunately the remains of 

 the smaller individual are very unsatisfactory, and Owen's genera 

 Pachyspondylus and Leptospondylus are founded on vertebras so 

 imperfect that it is doubtful if either can be regarded as satisfactory 

 types even if distinct from Massosponclylus, and it is pretty certain 

 one at least is founded on remains of Massospondylus carinatus. 

 The small individual possibly belongs to the species I am describing 

 as M. harriesi.
