from painted scenes on parietal surfaces is proved by the painting being 
continued on the side of the fractured slab. The technique and pigments 
are, however, those of the inland Bush, and this alone would go far to 
prove the identity of the Strand Looper with the Bushman as one race. 
The Bush painted and graved ; the Hottentot neither paints nor graves. 
Singularly enough the name Hottentot should apply to that race which is 
now dubbed Bushman. One of the scenes corroborates details of the 
Hottentot (Strand Looper) deportment given by Captain Beaulieu, who 
touched at Table Bay in 1621. 
Mr. S. H. Haughton exhibited an almost complete skeleton of a 
specimen of fossil reptile from the middle Beaufort Beds. 
The specimen exhibited was obtained by Dr. A. L. du Toit in Natal, and 
was associated with portions of skulls of undoubted species of Lystrosaurus, 
Apart from the fact that the skull and lower jaw are associated with the 
larger part of the skeleton, the specimen is of interest in that it seems to 
form a link between some Dicynodons of the Cistece^hahis zone and 
Lystrosaurus proper. The snout is bent down as in the latter genus, but 
it is not so greatly elongate. The relations of the bones of the top of the 
skull are typically Dicynodont. The upper border of the ilium is notched 
as in Lystrosaurus, but there are only two notches instead of three. In 
view of its intermediate character, it has been thought advisable to create 
for it a new genus Prolystrosaurus, which is also considered to include the 
form described as Dicynodon strigo^s. 
Mr. K. H. Barnard exhibited shells collected in Namaqualand by 
Dr. Rogers. 
Examples of most of the known species and varieties of the Dorcasiinae 
were shown together with some specimens of the allied sub-families from 
other parts of the world. Remarks were made on the supposed phylogeny 
of the family according to the recent anatomical researches of Watson and 
on the variation in the Helicoid form according to habitat. 
Dr. A. L. DU Toit exhibited some hybrid graphite-bearing rocks from 
Natal. 
These are found at the Ingeli and near Ladysmitli, and have been 
produced by the intrusion of dolerite into carbonaceous shale. The latter 
has been disrupted, and all stages are seen up to a breccia in which small 
fragments of shale are embedded in an igneous matrix, the sedimentary 
rock having been completely re-crystallised with the development of graphite 
and silicates, while the dolerite by reaction and incorjjoration of silica from 
the inclusions has been acidified and is now pale in colour.
