with lim bs almost as completely adapted for digging as those 
of a mole. It was first found in South Africa, but is now 
known by many nearly complete skeletons discovered by 
Professor Amalitzky in northern Russia. Its head-bones 
are coarsely sculptured, and the head of an apparently allied 
animal, Elginia, from the Trias of Elgin, is not only Wall-ease 
sculptured, but also armoured with large bony horns or spines 9 - 
(Wall-case 9). 
A diminutive Anomodont, Procolophon (Table-case 30), Table-ease 
from the Karoo Formation of Cape Colony, exhibits much 
resemblance to Pariasaurus, but may perhaps belong to 
another sub-order. Its head-bones are not sculptured, and 
its pineal foramen for the median eye is enormous. A nearly 
similar animal, Aristodesmus, has been found in the Lower 
Trias of Switzerland.

are very similar in many respects to those of Anomodonts. 
The vertebrse and limbs of the reptiles to which they belonged 
are not yet known, but these parts will probably prove to be 
adapted for life in the sea. The teeth are large grinding
