Comparison of these with the type pes of Massospondi/lus harriesi 

 shows that the phalanges of the digits have almost indentical measure- 

 ments in the two animals. The metatarsals in this animal have 

 different lengths, however, those of M. harriesi being somewhat longer, 

 except in metatarsal I. 



The metatarsals show few distinguishing features. The proximal 

 end of metatarsal II has the plantar edge considerably longer than 

 the dorsal, while the medial and lateral faces are both hollowed out 

 for articulation with the neighbouring bones. Metatarsal I looks almost 

 entirely inwards. Metatarsal IV is a much flattened bone, and its 

 distal end is slightly twisted inwards. Metatarsal V thins rapidly at 

 its proximal end and from the lateral face, and lies almost entirely 

 behind metatarsal IV. Its distal half shows the usual pads for the 

 reception of tendons or muscles, especially on the plantar surface. 



Among the collection of the Durban Museum submitted to me is 

 an incomplete animal from Foutanie, Fouriesburg, O.F.S. (the type 

 Ideality) consisting of a right scapula, a right hurnerus, a left coracoid, 

 a left fibula and digits 1, 2, 3, of a left pes. These closely correspond 

 with the type and must be placed within the species. The right 

 scapula has the ventral edge a little straighter than in the Blikana 

 specimen, being thus closer to the specimen described by van Hoepen 

 as Massospondylus broivni. The left libula has a maximum length of 

 about 285 mm. and a proximal surface 43 mm. long, and 20 mm. 

 wide. The bone is flattened laterally, especially at the distal end. 

 Its inner face at the proximal end is concave, its outer face convex. 

 The proximal end is slightly more slender than in the Blikana specimen. 

 The digits of the left pes correspond very closely to the type in size. 



It seems to me that van Hoepen is probably in error in assigning
