The ischium as preserved has a greatest length of 100 mm. Near 

 its junction with the pubis and ilium it has a width of 45 mm,, 

 while at its narrowest part the width was probably not more than 

 15 mm. 



THECODONTOSAURUS DUBIUS sp. nov. 



Two slabs of Cave Sandstone from Ladybrand, O.F.S., presented 

 to the South African Museum by Mr. van Niekerk contain the larger 

 part of the skeleton of a Thecodontosaitrus which seems to be specific- 

 ally distinct from any yet described from South Africa. A slab and 

 counter slab from the Cave Sandstone of Rosendal, O.F.S., now in 

 the Bloemfontein Museum, which I was kindly permitted to examine, 

 contain remains of a somewhat smaller animal apparently of the 

 same species. 



As usual with the Cave Sandstone fossils the bones are badlv

preserved, and it has only been possible to expose one side of the 

 type specimen. On the larger slab the dorsal and sacral vertebrae, 

 pelvis, and the hind limbs are seen in ventral aspect, while in 

 the smaller slab the caudal vertebrae are seen in lateral aspect 

 mostly as moulds. In the Bloemfontein specimen besides an imperfect 

 pelvis and hind limb there is preserved a very fine series of 54 

 caudal vertebrae. 



In the type specimen 13 dorsal vertebrae are seen on the ventral 

 surface - all crushed and weathered. The length of the posterior 

 vertebrae is 44 mm. each, and the breadth across the articular 

 surface is about 24 mm. Three sacral vertebrae are displayed. The 

 length of each of the first two is 45 mm., and the maximum breadth
