The type consists of two femora, 2 cervical vertebrae, a dorsal 

 vertebra, 3 caudal vertebrae, and some foot-bones from the Telle 

 River, separating Herschel from Basutoland. There is some doubt 

 as to whether all the remains are from the same animal, and von 

 Huene in his re-description has classed the vertebrae with Theco- 

 dontosaurus skirtopodus. From von Huene's account, the following 

 are taken as the salient points of the form. 



The femur is small, markedly S-shaped, with a compressed distal 

 end and a sagittal groove which divides the articular surface. The 

 bone is strongly compressed laterally. The fourth trochanter lies 

 wholly in the upper half of the bone. The head is rounded and 

 very thick. The length of the type is 24 cm. 



Von Huene notes that the femur is as large as that of Thecodon- 

 tosaurus cylindrodon, but at the distal end is smaller and has higher 

 and smaller condyles than T. .skirtopodus. The proximal end is 

 smaller and thicker than in T. antiqiius and T. cylindrodon. 



Van Hoepen has described under the name of Massospondylus 

 browni a fairly complete skeleton in the Transvaal Museum. I be- 

 lieve this to be a specimen of Massospondylus harriesi and have 

 discussed it in my description of that form.
