the mandible of Erythrosuchus and not that of Euskelesaurus. And 

 there is reason to suppose that the short cervical vertebra is also 

 that of Erythrosuchus. 



Orosaurus of Huxley was changed to Orinosaurus by Lydekker, 

 and the specific name capensis added. Huene has fully re-examined 

 all the Euskelesaurus remains, and gives a restoration of the 

 animal. He regards Orinosaurus capensis as but another species 

 of Euskelesaurus. 



HORTALOTARSUS SKIRTOPODUS, Seeley. 



MASSOSPONDYLUS BROWNI, Seeley. 



Hortalotarsus skirtopodus is founded on a fragment of the hind 

 limb of a small Dinosaur from Barkly East. Originally most of the 

 skeleton was in the rock, and it was regarded by the farmers as the 

 skeleton of a Bushman, but it is said to have been destroyed through 

 fear that a Bushman skeleton in the rock might tend to weaken the 

 religious belief of the rising generation. Huene is of opinion that 

 H. skirtopodus really belongs to the European genus Thecodonto- 

 saurus. 



In 1905 I described the hind limb, w r ith pelvis and some vertebrae 

 of a specimen which I thought might be referred to Hortalotarsus 

 skirtopodus, thinking the differences in size might be due to this 

 specimen being immature. If, however, Huene is right in regarding 

 H. skirtopodus as really a species of Tliecodontosauni*, and there is 

 little doubt that Hortalotarsus is at least allied to Tliccodontosaurus, 

 then the South African Museum specimen which I referred to 

 Hortalotarsus must be placed in a new genus. 



Massospondylus broivni is, like Hortalotarsus skirtopodus, only 

 known from a few remains. The femur, however, is well preserved, 

 and seems to show that the species belongs to Tliecodontosaurus, as 

 is maintained by von Huene. 



GYPOSAURUS CAPENSIS, g. et sp. nov. 



This new genus and species is founded on the South African 

 Museum specimen which I had referred to Hortalotarsus skirtopodus. 

 The two animals are of practically the same size, but the pelvis and 

 femur of the South African Museum specimen are very different 

 from those of Tliecodontosaurus, and must belong to a new genus. 



Among the chief characteristics of this new genus the most note- 

 worthy is the remarkable shape of the ilium. The iliac crest has 

 a greater anterior extension than in any other known carnivorous
