appear to be in fairly good health. In their stomachs are the 
remains of worms broken into segments, as in the fully toothed 
individuals. ° 
Though specimens in a similar condition have been obtained 
from other parts of S. Africa, they are rare. 
Chrysochloris asiatica varely suffers with its jaws, but a speci- 
men was exhibited in which the disease had led to extensive 
injury to the bone. 
(4) A skull of Chrysochloris hottentota with only eight teeth in 
each upper jaw, though there are the normal nine on each side 
of the lower. 
A new Thecodont Reptile.

Dr. Broom also exhibited the skull of a new type of Thecodont 
reptile (Youngina capensis) from the Upper Permian beds of 
South Africa, and remarked :— 
“ Hitherto, though there has been some evidence of the occur- 
rence of primitive Thecodonts in the Karroo beds of Upper 
Permian age, no satisfactory skull has been known. Some years 
ago I described the two types, Heleosaurus scholtzi and Heleo- 
philus acutus, both of Middle Permian age, and Watson is 
describing another form of the same age which may be allied. 
Unfortunately, little is known of the skull in any of these types. 
The new form which I ain exhibiting was found by me at New 
Bethesda, Cape Colony, in beds which are in the Cistecephalus 
zone, at least 600-1000 ft. below the Lystrosawrus zone, and most 
probably belong to the Upper Permian age. 
The specimen consists of the almost perfect skull of a small 
crocodile-like reptile, with a considerable series of vertebra, but 
unfortunately with no satisfactory remains of limbs or girdles, 
The skull measures about 60 mm. in greatest length, and is - 
42 mm. in width. The tip of the snout is missing, but as the 
anterior ends of the lower jaws are preserved, very little can 
have been lost. 
The orbits, which are situated near the middle of the skull, 
are large and are directed upwards and outwards. The antero- 
posterior diameter of the orbitis 17mm. The interorbital width 
is about 8 mm, 
Behind the orbit is an infratemporal fossa slightly smaller 
than the orbit, and a supratemporal fossa about a third of the 
size of the infratemporal.
