ItemForaminifera from the Upper Cretaceous beds occurring near Itongazi River, Natal.(Bernard Price Institute for Palaeontological Research, 1955) Smitter, Y. H.A small collection of foraminifera is described from the Upper Cretaceous beds occurring near the Itongazi river, Natal. One of the described species is new. The age of the fauna is demonstrated as Maestrichtian by briefly comparing local forms to similar index forms occurringc in Europe and North America where definite age relationships have been established. ItemA foraminiferal fauna from the tertiary sediments of Southern Moçambique(Bernard Price Institute for Palaeontological Research, 1955) Smitter, Y. H.A group of foraminifera is recorded from beds in Southern Mocambique of probable Upper Miocene age. The species listed are briefly compared with similar forms found elsewhere in the world. Three new species and one new variety are described. ItemFossil Hystricoidea from the Makapan Valley, Transvaal(Bernard Price Institute for Palaeontological Research, 1955) Greenwood, MarjorieIn this paper are described three Hystricomorphs from the Australopithecus prometheus layer of the Makapan Valley Limeworks Quarry, Transvaal. Besides Hystrix cf. H.africae-australis, a new genus and species Xenohystrix crassidens and a new species Hystrix major are recognized. ItemImportant new Anomodontia(Bernard Price Institute for Palaeontological Research, 1955) Toerien, M. J.In this paper descriptions are given of three new Anomodont specimens, to which reference was made in another paper on convergent trends in this group. These specimens are introduced as Propelanomodon devilliersi and Proaulacocephalodon miltoni, both new genera and species, and Dicynodon daptocephaloides, a new species. ItemNote 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. ItemOn 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. ItemOn 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. ItemPalaeontologia Africana, Annals of the Bernard Price Institute for Palaeontological Research, University of the Witwatersrand, Johannesburg, Volume III(Bernard Price Institute for Palaeontological Research, 1955)None ItemA study on the skeleton of Diademodon(Bernard Price Institute for Palaeontological Research, 1955)In this work the genus Gomphognathus is declared synonymous with the genus Diademodon. The small skeleton of "Microgomphodon", described by Seely in 1895, is recognised as possibly that of a newly "born" Diademodon. The structure of the skull is described in detail. Information was obtained from a wealth of fragmentary skull material belonging to many individuals of different ages. A special section is devoted to dentition and in another section new specimens are described, D. laticeps and D. parringtoni being introduced as new species. In dealing with the skeleton certain aspects of interest are analysed. An answer is sought for the peculiar arrangement of the lumbar ribs. The girdles are dealt with separately and attention is given to the dimensions of the pelvic girdle, in particular with a view to the probability of viviparity. Attention is also given to features which could throw light on aspects such a blood temperature, breathing, and the characteristics of the skin. ItemUne clavicule et un nouveau fragment mandibulaire d'Australopithecus Prometheus(Bernard Price Institute for Palaeontological Research, 1955) Boné, Edouard L.An acromial fragment of a collar.-bone of Australopithecus prometheus was found at the Limeworks Cave, Makapansgat (N. Transvaal). This specimen, which is the first ever discovered of the Australopithecine clavicle, is described and compared with both human (fossil and recent) and anthropoid bones. A left fragment of a lower jaw with a perfectly preserved and moderately worn third molar of the Makapan ape-man, found during the same sorting operation of the dumps (April 1955), is discussed here: size and pattern emphasize the homogeneity of the prometheus finds, their close relationship to Teianthropus, and their human affinity.
