Whilst collecting on the farm Hottentots Rivier, Field Cor- 
netcy Gouph No. 3, District Beaufort West, Cape Province, from 
the Pariasaurus zone, I was given a lump of the or diene 
quartzitic sandstone of that horizon showing an extremely sharp 
impression of a small lizard-like reptile. By careful development 
I exposed a perfectly preserved car pus and tarsus with the actual 
bone well preserved, and the specimen now allows of a very 
complete account of the animal’s structure. 
Skull—The skull is represented only by an exquisitely sharp 
impression of the buccal surface of the palate, squeezes from 
which show its structure with perfect clearness. 
The basioccipital is not definitely visible, but it may be 
represented by a rather faint impression behind the basisphenoid ; 
it is, however, equally probable that this represents the atlas. 
The basisphenoid is very broad, the lower surface is shallowly 
concave, the lateral borders being raised into low, sharp-edged 
ridges which shghtly separate posteriorly and end in ill-marked 
tubera. Anteriorly the bone bears two well-marked basipterygoid 
processes which, so far from projecting downwards, lie above the 
general level of the lower surface of the bone; they are directed 
forwards, and their flat articulating surfaces are nearly at right 
angles to the length of the skull. Between these processes the 
parasphenoid projects forward as a very narrow rostrum of 
considerable length ; where it joins the basisphenoid it separates 
distinct grooves on each side of the middle line which lead from 
the palate into the skuJl. There is some evidence that the 
parasphenoid terminated behind in a diamond-shaped expansion 
on the lower surface of the basisphenoid. 
There are no carotid foramina.
