In our form this is the reverse. Similar differences can be found in the 
foot. 
The lengths of the metatarsalia of Thecodontosaurus shirtopodus show rela- 
tions to each other which differ from those of our form. 
Only the femora are known of Thecodontosaurus Browni. If the femur of 
Thecodontosaurus Browni and that of the present specimen are given the same 
length as that of Dromicosaurus, and the lower end of the femur of Masso- 
spondylus*carinatus be given the same length as the lower end of the Dromico- 
saurus femur, then the other measurements become as tabulated below (in 
centimetres) : 
Dromicosaurus gracilis 
Thecodontosaurus Browni 
Present specimen 
Massospondylus carinatus 
These measurements show that there is a fairly big difference between the 
femora of Dromicosaurus gracilis and of Thecodontosaurus Browni, and also 
between those of our present specimen and of Massospondylus carinatus. The 
difference, however, between the femur of Thecodontosaurus Browni and that 
of the present form is very slight. The difference is so slight that, together 
with the consideration that our specimen is badly preserved, I do not feel 
myself justified in ascribing them to different species. 
The genus to which they belong cannot be Dromicosaurus. Except the 
difference in the femora, there is a great difference in the relation of femur 
and tibia. The tibia is relatively much longer, with regard to the femur, in 
the present form than in Dromicosaurus . As preserved, the articulatio iliaca 
of the ischium of the present form makes a much larger angle with the general 
long axis of the bone than that of Dromicosaurus. It is difficult to conceive 
that this could be the result of pressure alone. The proximal hollow surface 
between the articulatio iliaca and the articulatio ischio-pubica seems to be 
relatively larger in Dromicosaurus . Could the required genus be Massospon- 
dylus ? It is difficult to say. The ileum of Massospondylus carinatus is practi- 
cally the same as in the present form, but the trochanter major lies relatively 
so much lower in Massospondylus carinatus. However, this is the only prin- 
cipal difference which I could find. Considering the bad condition of the 
present specimen I think it will be better to place it in the genus Massospon- 
dylus and keep it there till it can be definitely proven to belong somewhere 
else. 
Some time ago our collector at Harrismith found some Dinosaurian remains 
on the commonage. They consist of a vertebra and some phalangeal bones, 
and although they could not be identified as to genus or species, they are 
here described because they are so well preserved and because the vertebra 
shows a remarkable vertical ridge, running upwards from the articulation 
surface for the capitulum costae. There is no indication whatever that these 
bones belong to one individual.
