This is a very imperfectly known species, the type consisting of 

 a claw phalanx and the distal end of a metatarsal. 



The species is apparently about four-fifths the size of Gryponyx 

 nfricanus; according to Dr. Broom "it differs in having a much less 

 developed tubercle for the ilexor tendon which makes the flexor surface 

 less curved and gives the whole claw a less hooked appearance". Van 

 Hoepen, however, considers that "the greater part of the tuberositas 

 for the flexor tendon is broken away". He further thinks that the 

 claw belongs, not to the right hand, but to the left; and that it differs 

 from his Massospondylus brotcni (i. e. M. Jutrriesi) in that the proximal 

 end of the lateral side ridge lies relatively much higher with regard 

 to that of the medial side in G. transvaalensis.

The remains forming the type of this new form were discovered 

 in 1915 in the neighbourhood of Fouriesburg, Orange Free State, in 

 an exposure near the top of the Red Beds. They consist of the 

 pelvic girdle and sacral vertebrae found in conjunction. 



Vertebrae. Three sacral vertebrae were found in situ between the 

 two sides of the pelvis, somewhat flattened from side to side. The 

 first centrum is not fused to the second. 



The second and third vertebrae are of equal length, and each slightly 

 longer than the first. The centra are higher than wide with concave 

 ends. The ventral border of the first is more excavate than those 

 of the other two ; the centrum of the third is more excavate post- 

 eriorly on its lower border than anteriorly. The lower border of 

 each is sharply rounded, but not keeled nor pointed. The first centrum 

 is 79 mm. long, the others each 8i mm. The posterior surface of 

 the third centrum is 82 mm. high.
