- ItemThe species relationships and stratigraphic distribution of Southern African upper Cretaceous Epistomina(Bernard Price Institute for Palaeontological Research, 1958-06-01) Smitter, Y. H.Briefly set forth are the phylogenetic inter-relationship of the various species of the foraminiferal genus Epistomina occurring. in the upper Cretaceous of Southern Africa. The known stratigraphjc ranges of the forms as they occur in Southern Africa are presented.
- ItemOn the significance of tuskless specimens of Dicynodon grimbeeki Broom(Bernard Price Institute for Palaeontological Research, 1958-06-01) Barry, T. H.It has hitherto been accepted that Dicynodon grimbeeki, a species of the extinct Karroo mammal-like reptiles, possesses canine tusks in the males only. This theory is discussed in detail. An investigation is also made of the extent of the influence of sexual dimorphism on the dentition of extant forms. It is concluded that the evidence against the theory that the males only are tusked is such that it cannot be accepted.
- ItemOn the skeleton of Aneugomphius ictidoceps Broom and Robinson(Bernard Price Institute for Palaeontological Research, 1958-06-01) Brink, A. S.The skeleton of Aneugomphius ictidoceps was not taken into consideration with the original description and became separated from the type skull. After the present author had submitted a more detailed description of the type skull for publication, the skeleton was discovered where it had been kept in store. Subsequently the skeleton was cleaned and is described and figured in this paper. A dorsal and a side view of the reconstructed skeleton are also given.
- ItemStruthiocephalus kitchingi sp. nov.(1958-06-01) Brink, A. S.In this paper a new species of the Tapinocephalid Dinocephalian Struthiocephalus (S. kitchingi) is described, based on a good skull without lower jaw, adding not only to our knowledge of the structure of the skull of this genus, but also exhibiting more pronounced features on the strength of which some idea may be formed regarding the mode of living of the animal. This specimen differs appreciably from the known species, S. whaitsi, S. rheederi, S. milleri, and S. akraalensis, but where some of the differences appear even to transgress the generic boundary, it is considered that previous descriptions are not based on absolutely perfect material. Even the present specimen does not exhibit its structural detail so clearly that a wrong interpretation should be considered as excluded.
