Dinosaur, and the preacetubular process relatively small. The 

 femur is relatively stout, and has the troclianter quartus small and 

 high up, and the trochanter major almost rudimentary. 



All the remains of any importance are figured in a paper in the 

 Trans. South African Phil. Soc., vol. xvi., pt. 3, 1906. 



GRYPONYX AFRICANUS, g. et sp. nov. 



Recently there was discovered on the farm of Mr. J. L. Harries, 

 Foutani, near Fouriesburg, in the Orange Free State, a considerable 

 number of remains of Dinosaurs, and the more accessible have been 

 excavated by Mr. A. E. Walker, of the South African Museum, 

 with Mr. Harries' assistance. All the remains are from the Eed 

 beds. 



The most important is a large carnivorous Dinosaur allied to 

 Plateosa unis of Europe, but apparently belonging to a new genus 

 and species which I have named as above. The anterior half of the 

 animal has been lost, but Mr. Walker and Mr. Harries were suc- 

 cessful in obtaining both the right and left manus, most of the dorsal 

 vertebrae, the whole pelvis, both hind limbs, and the right pes. The 

 -greater part of the tail had to be left in the rock, as, owing to its 

 passing straight into the cliff, it could not have been all removed 

 except at very great expense. 



The vertebras have not yet been completely developed, but so far 

 as can be seen they appear to agree fairly closely with those of 

 Plateosaunis. 



The radius and ulna are both well preserved in their distal halves, 

 but imperfect proximally. The shapes of the distal ends are seen 

 in the figures. 



In the carpus there are seven elements, and though there is some 

 doubt concerning the determination of one or two, most can be 

 determined with certainty and the others with much probability. 

 The 1st, 2nd, and 3rd distal carpalia are in undisturbed relations 

 with the rnetacarpals, and there can be practically no doubt about 

 them. All the proximal carpals are small, and in the specimen 

 three lie below the end of the radius. These I believe to have been 

 displaced and to be the radiale, the intermedium, and the ulnare. 

 While this seems to be the natural determination of the three 

 proximal elements, it is confirmed by the fact that they can be 

 fitted in their natural position on the proximal side of the distal 

 carpalia. The 7th element is small, and from its situation by the 

 side of the 3rd carpale it is evidently the 4th carpale.
