    Note on a very tiny specimen of Thrinaxodon liorhinus
    (Bernard Price Institute for Palaeontological Research, 1955) Brink, A. S.
    This paper describes a specimen of Thrinaxodon liorhinus, evidently a mature female, with a very tiny specimen closely associated with it in the same nodule. Attention is largely given to tooth replacement. The conclusion arrived at is that Thrinaxodon has not yet reached that stage in evolution where light is thrown on the development of the typical mammalian arrangement of dental succession.

    On Nanoparia Broom
    (Bernard Price Institute for Palaeontological Research, 1955) Brink, A. S.
    New information on the types of Nanoparia pricei and Nanoparia luckhoffi are given in this paper. Differences between the two species recognised previously are disputed and a number of different distinguishing characteristics is suggested. The new information could be revealed as a result of further development of the specimens. The type of N. pricei includes a portion of the skeleton, developed after the skull was described. This portion reveals an interesting arrangement of dermal scutes.

    On the Cynognathidae
    (1955) Brink, A. S.
    In this paper attention is drawn to the fact that the family Cynognathidae is as a whole very badly known and in need of taxonomic revision. Unfortunately the author had too little material available to attempt a proper revision, but some suggestions are made. The paper starts with a brief historical account and continues with descriptions of a lower jaw of a Cynognathid, evidently belonging to the genus Lycaenognathus. This specimen belongs to the Bernard Price Institute. Attention is further drawn to the complete absence of convincing characteristics for distinguishing between the genera Cynognathus and Cynidiognathus, but they are nevertheless acknowledged as distinct genera. Four specimens are described as Cynidiognathus merenskyi , one of which belongs to the Bernard Price Institute and the other three to the National Museum, Bloemfontein.
