    New fossil Cercopithecoidea from the lower Pleistocene cave deposits of the Makapansgat Limeworks, South Africa
    (Bernard Price Institute for Palaeontological Research, 1970) Maier, Wolfgang
    So far about 70 specimens of five species of Cercopithecoids have been recorded from the Makapansgat Limeworks. The present paper adds the descriptions of another 20, some of them being the most complete skulls known of these species: Cercopithecoides williamsi is represented by a nearly complete male skull; its large upper teeth confirm the invalidity of the former species C. molletti. Parapapio jonesi is represented by parts of a young female and two adult males. The male material is the most comprehensive known of this species and made it possible to give a reconstruction of the male skull. Specimen M.2961, described by Freedman (1960) as Parapapio broomi, is referred to P. jonesi. Of Parapapio broomi 7 new specimens are recorded and described. A fragmentary male skull (M.3065) and a very large mandible (M.3067) most probably belong together, giving a good idea of the male skull of this species. Of Parapapio whitei the first fairly complete male skull could be prepared and described. In the light of the new specimen, some of the male specimens, formerly referred to this species (Freedman 1960; 1965) should be removed. Simopithecus darti is represented by a nearly complete and undistorted skull of a sub adult female, with the mandible being in situ. In addition, a nearly complete mandible of a young male and a fragmentary maxilla of an old male could be described. Some of the teeth of these specimens nearly equal those of Simopithecus danieli from 'Swartkrans.

    The anterior of the palate in Euparkeria
    (Bernard Price Institute for Palaeontological Research, 1970) Gow, C. E.
    Ewer (1965) has given a careful and comprehensive description of the anatomy of the thecodont Euparkeria, but erred if anything on the side of caution in her preparation of the material. This is a commendable approach, but it has meant that certain details remained unknown. Recently Cruickshank (1970) has redescribed and reinterpreted the braincase as being surprisingly primitive. The present author's current interest lies in the origin of the lizards, and this necessarily implies an interest in Archosaur origins. In this regard an important element of the skull is the vomer; this will become apparent when recently completed work on the Millerosauria is published (Gow 1971). The important feature is the nature and disposition of vomerine teeth. Not surprisingly the vomer is not known in detail in any "Eosuchian" or early lepidosaur, as it usually lies hidden by the symphysis of the lower jaws and in any event requires delicate preparation.

    Revised classification for Makapania broomi Wells and Cooke (Bovidae, Mammalia)
    (Bernard Price Institute for Palaeontological Research, 1970) Gentry, A. W.
    Details of skull morphology, particularly of the basioccipital, show that Makapania broomi from the Makapansgat Limeworks Quarry, Transvaal belongs to the tribe Ovibovini, and is very like Megalovis latifrons Schaub, best known from the later Villafranchian of Seneze, France. The Ovibovini have only two living species, but in the Pliocene and early Pleistocene they must have been more widespread than hitherto suspected. Makapania broomi is the first clear record from Africa south of the Sahara of a fossil member of the Eurasian and North American subfamily Caprinae.
