| Some time ago Mr. G. M. Roding, director of the natural history museum at Enschede, sent me for identification two mandibular fragments with teeth of a large rodent collected in the clay pit at Needse Berg, province of Gelderland, by Mr. Ten Bokkel Huinink, the owner of the pit. The Neede Clay, Needian of Dutch terminology (Van der Vlerk and Florschütz, 1950, p. 149), is characterized by the abundance of the freshwater molluscs Viviparus diluvianus (Kunth) and Valvata naticina Menke; the scanty remains of large mammals found in this deposit, representing Elephas antiquus Falconer, Cervus elaphus L., and Dicerorhinus merckii (Jäger), were described already half a century ago by Rutten (1909). The Neede Clay corresponds to the great Mindel-Riss Interglacial;... |

| The material to be described below forms part of a collection of fossil vertebrates made by Dr. J. Cosijn North of Djetis and Perning in Eastern Java (Cosijn, 1931, 1932). The Cosijn collection has not yet been fully described, some preliminary identifications were made by the late Prof. Dr. J. H. F. Umbgrove (in Cosijn, 1931, pp. 118-119). The collection is preserved in the Geological Museum at Leiden ; I have previously described the remains of rhinoceros (Hooijer, 1946, pp. 3, 55, 73, and 76) and those of hippopotamus (Hooijer, 1950, pp. 66, 69-72, and 87-108). It is a pleasure again to acknowledge my indebtedness to Prof. Dr. B. G. Escher and to Prof. Dr. I. M. van der Vlerk for permission to study this valuable material. Umbgrove's first conclusion... |

| For a study in progress on the fossil Bovidae collected in Java by Eug. Dubois the necessity was felt to create a new genus for the inclusion of the species described as Leptobos groeneveldtii by Dubois (1908, p. 1261). The diagnosis is presented in this place in order that the name may be made available. Epileptobos gen. nov. Diagnosis: Large Bovinae with relatively broad and low skull. Horns in both sexes. Parietal extremely short, forming a sagittal crest that begins opposite the centre of the horn cores, and passes backward into a strong triangular parieto-occipital eminence, much raised above the fronto-parietal suture and overhanging the occipital. Temporal crests prominent. Occiput triangular in back view, the top of the triangle being formed by the... |

| INTRODUCTION The fossil specimens of rhinoceroses recovered at the "Elandsfontein" site, Hopefield, Cape Province, belong to the two living species of Africa, viz., Ceratotherium simum (Burchell) and Diceros bicornis (L.) (Singer, 1954). Both are widely distributed in the African Pleistocene (see Hopwood and Hollyfield, 1954), and their distinguishing dental characters have been described by Cooke (1950). The purpose of the present publication is to place the Hopefield material on record. The general age of the Hopefield fauna is considered to be early Upper Pleistocene, but it is probable that part of the fauna dates from the late Middle Pleistocene (Singer, 1957). In the material recorded below Ceratotherium is about four times less abundantly... |

| In a recent monograph, Maglio (1973) states that Stegodon hypsilophus Hooijer (1954a) must be considered a synonym of Elephas celebensis (Hooijer, 1949). Though Elephas celebensis is smaller-toothed and more hypsodont than the "hypsilophous stegodont" of Java (width of M3 42-52 mm against 62-64 mm; height-width index 106-116 against 87-89: Hooijer, 1954a, b; Maglio, 1973: 46, table 21), Maglio (1973: 47) considers the differences not great when the degree of variation of known samples (in other species) is allowed for. Over the years, I studied molars of pygmy proboscideans from various Indonesian islands, and it never occurred to me that the Java pygmy would be same as that from Celebes until this suggestion was put forth by Dr. Maglio. I had described... |
