Item 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.Item THE ANTERIOR OF THE PALATE IN EUPARKERIA(BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1970) Gow, C. E.In view of the central position of Euparkeria in the accepted phylogeny of the Archosaurs it was considered necessary to examine the vomer, and to this end one of the skull blocks listed by Ewer (SAM 6050) was prepared in formic acid. This yielded in addition to the vomers, important new information on the internal structure of the maxillae. The vomer stresses the primitive nature of the animal while the structure of the maxilla considerably strengthens its affinities with later archosaurs.Item CONTRIBUTION A LA CONNAISSANCE DES ICTIDORHINIDES (GORGONOPSIA)(BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1970) Sigogneau, DeniseLe materiel d'Ictidorhinide disponible est actuellement limite, rappelons-le, a neuf echantilIons: sept consistent en un crane isole, tandis que les deux autres comportent quelques elements post-craniens. Ce dixieme exemplaire n'apparaft donc pas negligeable, d'autant moins que la plupart des echantillons sont assez mal conserves et qu'en consequence l'anatomie cranienne de la famille reste encore imprecisee; or cette famille constitue certainement l'une des plus interessantes des Theriodontes du point de vue de la morphologie evolutive.Item CONTRIBUTION A LA CONNAISSANCE DES ICTIDORHINIDES (GORGONOPSIA)(BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1970) Sigogneau, DeniseLe materiel d'Ictidorhinide disponible est actuellement limite, rappelons-le, a neuf echantilIons: sept consistent en un crane isole, tandis que les deux autres comportent quelques elements post-craniens.

Le crane etudie ici fut decouvert par Mr. J. W. Kitching, et nous a ete prete avec l'accord du Gouvernement Sud-Africain. Notre dette de reconnaissance envers l'un et l'autre s'en trouve encore accrue.Item EPIDERMAL REMNANTS OF PROTEROSUCHUS VANHOEPENI (HTN)(BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1970) Thornley, A. L.Epidermal remnants from Proterosuchus vanhoepeni are described. The significance of these findings is briefly discussed.Item Epidermal remnants of Proterosuchus vanhoepeni (HTN)(Bernard Price Institute for Palaeontological Research, 1970) Thornley, A. L.NoneItem A new check-list of fossil Cercopithecoidea of South Africa(Bernard Price Institute for Palaeontological Research, 1970) Freedman, LeonardDuring 1970, the opportunity was afforded me to spend several weeks in South Africa, studying and identifying the cercopithecoid fossils which have been found recently. The new specimens have been recovered, in the main, by Professor P. V. Tobias and Mr. A. R. Hughes at Sterkfontein, and by Dr. C. K. Brain at Swartkrans and Kromdraai; in addition, further specimens have been developed from the Makapansgat breccia at the Bernard Price Institute for Palaeontological Research. At the request of Professor Tobias, I have compiled a new check-list of the fossil Cercopithecoidea from South African Pleistocene deposits.Item A NEW CHECK-LIST OF FOSSIL CERCOPITHECOIDEA OF SOUTH AFRICA(BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1970) Freedman, LeonardAt the request of Professor Tobias, I have compiled a new check-list of the fossil Cercopithecoidea from South African Pleistocene deposits. This list is a revision of the check list published in my monograph of 1957. It is based upon all the papers I am aware of, which have been published since then, as well as the results of my recent visit.Item New fossil Cercopithecoidea from the lower Pleistocene cave deposits of the Makapansgat Limeworks, South Africa(Bernard Price Institute for Palaeontological Research, 1970) Maier, WolfgangSo 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.Item NEW FOSSIL CERCOPITHECOIDEA FROM THE LOWER PLEISTOCENE CAVE DEPOSITS OF THE MAKAPANSGAT LIMEWORKS, SOUTH AFRICA(BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1970) Maier, WolfgangSo far about 70 specimens of five species of Cercopithecoids have been recorded from the Makapansgat Limeworks.

A.The purpose of this communication is to establish the presence of a species of Stahleckeriid, hitherto known only from India, in the Zambian Triassic N'tawere Formation and to establish the new specific name of the Kannemeyeria specimen also recorded from the same locality.Item Preliminary report on two Triassic dicynodonts from Zambia.(Bernard Price Institute for Palaeontological Research, 1970) Crozier, E. A.The purpose of this communication is to establish the presence of a species of Stahleckeriid, hitherto known only from India, in the Zambian Triassic N'tawere Formation and to establish the new specific name of the Kannemeyeria specimen also recorded from the same locality. The skulls and some post-cranial material of these two dicynodonts were collected by Mr. James Kitching from the Luangwa Valley, Zambia in 1961. The material comes from Locality 16, of the Lower Fossiliferous Horizon in the N'tawere Formation. One large skull has been assigned to genus and species Rechnisaurus cristarhynchus Roy Chowdhury, 1970. The other skull and the postcranial material has been named Kannemeyeria latirostris sp. nov. One other specimen has been described from this locality, Diademodon rhodesiensis (Brink 1963), which marks it as being of near Cynognathus-zone age.Item A PRELIMINARY REVIEW OF THE BIOSTRATIGRAPHY OF THE UPPERMOST PERMIAN, TRIASSIC AND LOWERMOST JURASSIC OF GONDWANALAND(BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1970) Anderson, H. M.; Anderson, J. M.This review pager was born out of a desire to visualize in some detail the picture of the evolving Gondwana Triassic landscape and the story of life and ecology upon it; a desire to provide a general setting in which to view the details of the work in which we are actively involved at the present-the macro flora (H.M.A.) and microflora (J.M.A.) of the Molteno 'Formation' of the Karroo Basin of South Africa.Item 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.Item Revised classification for Makapania broomi Wells and Cooke (Bovidae, Mammalia)(Bernard Price Institute for Palaeontological Research, 1970) Gentry, A.

H.The Cistecephalus zone pareiasaurs all show skin armour. The fea tures of this armour are described as found virtually complete in a small pareiasaur, identified here as an about half-grown Pareiasaurus serridens. Different in skin structure from this small pareiasaur is the dwarf-form, Nanoparia pricei. A few particulars have now been added to the known skin structure of this species. It is suggested that Cistecephalus zone pareiasaurs can be referred to 2 principal species: the one is Pareiasaurus serridens Owen, to which all the incomplete and variably grown specimens can be assigned such as the genus Propappus and some other species from the genera Pareiasaurus, Anthodon and Nanoparia. The other consists of the single specimen Nanoparia pricei. Further affinities are beyond existing evidence to settle.Item Skin structure of small pareiasaurs. With comments on their taxonomy in the Cistecephalus Zone(Bernard Price Institute for Palaeontological Research, 1970) Findlay, G. H.The Cistecephalus zone pareiasaurs all show skin armour.

F.A short historical review is given of previously described sites where plant fossils occur in Lower Karroo beds at Vereeniging in the Southern Transvaal. Reference is made to the importance of these sites because of the outstanding discoveries made here in the past. Some new material from the same sites is described and several unusual elements in the Glossopteris flora of Vereeniging are recorded for the first time. Leaves of a plant not previously recorded from Gondwanaland are provisionally described under the term cf. Nephropsis on account of a strong resemblance to leaves of the Russian Permian genus Nephropsis Zalessky. The remaining specimens in the assemblage are tentatively placed in the genera Ginkgoites Seward and Psygmophyllum Schimper respectively. Owing to the paucity of material, type numbers are assigned in certain cases, instead of specific names. Specific identification is attempted, however, in the case of four of the specimens, which are provisionally assigned to Psygmophyllum kidstoni Seward.
