    On the scaloposaurid skull of Olivieria parringtoni, Brink with a note on the origin of hair
    (Bernard Price Institute for Palaeontological Research, 1968) Findlay, G. H.
    Olivieria parringtoni was described by Brink in 1965 as a new genus and species. It stands closest, among the scaloposaurids, to Ictidosuchops intermedius (Broom). In general shape and size, their skulls are virtually indistinguishable from one another, but Olivieria comes from the top of the Lystrosaurus-zone (early Triassic) while the type-locality of I. intermedius is the Cistecephalus-zone (Upper Permian). Differences in dentition and differences in detailed skull moulding had argued for the creation of the new genus.

    On the structure of the skin in Uranocentrodon (rhinesuchus) senekalensis, Van Hoepen
    (Bernard Price Institute for Palaeontological Research, 1968) Findlay, G. H.
    In the famous collection of fossil remains of the labyrinthodont Uranocentrodon, housed since 1911 in the Transvaal Museum, the bony skin armour from the ventral surface of the body of at least six individuals has been preserved. In spite of this lavish quantity of material only a few notes on the osseous skin structure were included in van Hoepen' s (1915) description, and all later papers have passed it by almost completely.

    On the Lystrosaurus zone and its fauna with special reference to some immature Lystrosauridae
    (Bernard Price Institute for Palaeontological Research, 1968) Kitching, J. W.
    In the past, collecting from the middle Beaufort Beds or Lystrosaurus zone has been badly neglected by field workers mainly due to the monotonous occurrence of the genus Lystrosaurus. Collecting has mostly been undertaken in such areas as the Harrismith Commonage, Oliviershoek Pass, Bergville or where there was a good possibility of finding either Thrinaxodon, Glochinodontoides or other faunal remains more exciting than Lystrosaurus.

    The lithic industry in the Makapansgat Limeworks breccias and overlying surface soil
    (Bernard Price Institute for Palaeontological Research, 1968) Maguire, Brian
    The excavations directed by Professor Dart at the Makapansgat Limeworks, and conducted mainly by myself at the site since 1960, were concerned during the 1963- 1965 field seasons with an examination of the surface soil overlying the consolidated pink breccias, and of the contents of the abundant solution cavities which penetrate the underlying breccia mass to depths of up to 15 feet or more. The shallow soil , overlying and mainly derived from the consolidated australopithecine breccias, contains an abundance of crude artefacts which are largely composed of chert, a material native to the dolomitic cavern site. The most characteristic tools are various kinds of notched scrapers which are more particularly described. The undoubted relationship of these artefacts to those occurring in the underlying breccias is also discussed.
