| In 1944 Miss Dr. A. Schreuder sent me for identification a fossil horncore, which according to the accompanying letter came from a well-boring near Grubbenvorst (province of Limburg). It was found in a coarse sandy layer with gravel at a depth of 61.50 m below the surface; the topographic height of the latter is given as 24.53 m + N.A.P. (N.A.P. = sea-level at Amsterdam). Dr. J. F. Steenhuis, geologist to the Government Geological Foundation, informed me that deep borings for the water-supply of Central-Limburg have been made in the years 1918, 1919, and 1922 S. and S.E. of Grubbenvorst. Evidently we have to do with boring no. I of October 1918, which reached a depth of 83 m, the top being at 24.50 m + N.A.P. (Geological Foundation Index no. 695/4). The... |

| The genus Celebochoerus was based by me (Hooijer, 1948) on two fragments of upper canines of rather large size, different from their homologues in Sus celebensis Müller and Babyrousa babyrussa (L.), the two living species of Suidae of Celebes. The specimens originate from Pleistocene deposits at Desa Beru, Tjabenge (Sopeng district), about 100 km N.E. of Macassar, S. Celebes, and were collected by Mr. H. R. van Heekeren, prehistorian to the Archaeological Survey at Macassar. In the meantime I have received more specimens of upper canines, collected by Mr. Van Heekeren at Desa Beru and also at Sompoh, 12 km N. of Beru. These specimens, like those first described, are surface finds and consequently more or less water-worn. They show a great deal of variation... |

| The genus and species Turkanatherium acutirostratus was proposed by Deraniyagala (1951) for a skull, without the mandible, collected by Dr. H. B. S. Cooke, a member of the Wendell-Phillips Expedition to Africa in 1948, at Moruaret Hill (or Moruorot) near Losodok (or Lothidok) in the Turkana district, Kenya. The holotype is in the Colombo Museum, Ceylon. Dr. Deraniyagala has had the courtesy to send me a series of good photographs of the specimen to supplement his own descriptions and published figures, for which I am very grateful. This has enabled me to identify among material in the Tervuren Museum, Belgium, originating from (Early) Miocene deposits at Karugamania, Lake Albert, Western Rift Valley in Congo, a number of teeth pertaining to the very same... |

| 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... |

| SYNOPSIS A rhinoceros from the Fort Ternan site, Kenya, Late Miocene in age, represents a form distinctly more advanced than the genera and species known from the Early Miocene although it is not directly ancestral to the Quaternary forms. It is a collaterally developed tuskless, two-horned, browsing species from the same ancestral stock as the modern Diceros bicornis (L.), and it is named Paradiceros mukirii. This is the first rhinocerotid filling the gap between the African Early Miocene and the Pleistocene rhinocerotids. Through the courtesy of Dr. L. S. B. Leakey the writer has been priviliged to study the rhinocerotid remains of the Fort Ternan site, housed in the Centre for Prehistory and Palaeontology, National Museum, Nairobi. The site, whence came... |

| A sirenian skeleton, the major part of which was excavated from Miocene deposits at Eibergen near Winterswijk, belongs to Metaxytherium. The temporal crests on the parietals are well separated. The foramen magnum is pointed above. The mandible has a downturned symphysial body with four shallow alveoli on each side. The wide mandibular canal opens some distance behind the alveolus of M3. There are alveoli for one premolar (P4) and for three molars (M1-M3). Only M2 dext. is preserved; it has four main cusps and some accessory cusplets. The humerus, the shaft portion of which is missing, has a wide and marked bicipital groove. The vertebrae, with the exception of the atlas, are fragmentary. The spinous processes are solid, the centra porous. The ribs, a few... |

| The purpose of the present paper is to place on record data on fossil Rhinocerotidae from Africa not included in earlier papers. Material has turned up in Africa in great quantities over the last decade, much from beautifully calibrated sequences especially in Ethiopia and the Baringo area of Kenya. Dreary descriptions of fossil teeth and bones are simply a prerequisite to construct, as is my aim, a sort of phylogeny of the rhinoceroses of Africa comparable to those long established for Europe or America. We have at this moment seven genera and a dozen or so species of Rhinocerotidae from the Neogene and the Quaternary, which will be dealt with below. My research in East and South Africa has been supported by grants-in-aid from the Wenner-Gren Foundation... |

| Although the discovery of the elephantine mentioned in the title of the present contribution dates from the early days of collecting in the Siwalik Hills (Falconer and Cautley, 1845, pl. 2 figs. 5a, 5b, as Elephas planifrons the stratigraphical position of this species within the tremendously thick Siwalik series of continental deposits was first settled only in 1913, when Pilgrim wrote: “There is absolutely no trace of Elephas either in the Middle Siwalik or in the Tatrot zone of the Upper Siwalik. It first appears as the species Elephas planifrons some 2,000 feet above the base of the Tatrot zone” (Pilgrim, 1913, p. 294), that is, within the Pinjor zone. Hence, Pilgrim (1. c., pl. 26) assigns Archidiskodon planifrons (Falconer et Cautley) to the Pinjor... |

| A male skull of Tapirus terrestris (L.) originating from Dutch Guiana (Leiden Museum, reg. no. 11632), received from the Rotterdam Zoological Garden through the kind intermediary of Mr. F. J. APPELMAN on July 15, 1952, is remarkable for the abnormal development of its right P1. The full permanent dentition is in place except for the posterior premolars and last molars, which are in alveolo. The teeth are but little worn and, apart from the right P1, they do not show anv unusual characters. The left P1 has the shape normally found in the Brazilian tapir; the crown is triangular with rounded angles, and bears a continuous outer crest (ectoloph) extending from the front angle (parastyle) to the posterior outer cusp (metacone). The position of the central... |

| 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... |

| 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... |

| The fossil remains of rodents described in the present paper are from various localities. The large extinct musk rat Megalomys occurs in reddish-brown phosphatic “oolite” fillings of irregular cavities in a marine limestone found by Mr. P. H. DE BUISONJÉ in the north-western part of the Duivelsklip, eastern Curaçao, about 50 m above sea-level. The “oolite” also contains scanty remains of lizards, snakes, and of a bat. Fragmentary molluscs present possibly include Cerion uva (L.), a recent, very common, terrestrial species, as well as other gastropods, many opercula of which were found. Samples of a phosphatic “oölite” deposit collected in 1937 by Dr. P. WAGENAAR HUMMELINCK from an escarpment near Fontein, Bonaire, proved to contain jaws, with teeth, of a... |

| The faunas of Lothagam, Kanapoi and Ekora on the west side of Lake Rudolf in Kenya include well-preserved Hipparion material. The most interesting species is represented by a skull from Lothagam that is devoid of a preorbital fossa : Hipparion turkanense Hooijer & Maglio. The upper cheek teeth have small fossette plications and rather wrinkled anteroposterior fossette borders; the lower cheek teeth also show this wrinkled enamel condition, notably on the buccal wall, and sport no ectostylids. The closest resemblances are with certain Chinese "Pontian" forms described by Sefve. An equally large Hipparion with a preorbital fossa occurs at Kanapoi and Ekora. The upper cheek teeth are richly plicated fore and aft, and the anteroposterior fossette borders... |

| The Laetolil Beds in Tanzania, 20-30 miles south of Olduvai Gorge, have been extensively sampled by parties under the leadership of Mrs. Dr. Mary D. Leakey, who very kindly sent me Hipparion material collected in 1974, 1975, and 1976. In a restudy of proboscidean material from these beds described by Dietrich (1942), Maglio (1969) arrived at the conclusion that the Laetolil fauna represents two distinct horizons, one seemingly correlating best with Kanapoi, Yellow Sands (= Mursi Formation), Chemeron, and Kanam, and younger deposits correlating best with the later Omo Beds, possibly antedating Olduvai Bed I but only by a short time interval. This has been confirmed by radiometric dating: the Laetolil Beds with the older fauna are bracketed in time between... |

| The animal remains (mostly of shells, fish, and turtles) collected by Mr. H. R. VAN HEEKEREN and Mr. C. J. DU RY at the Indian site Sint Jan II, Curaçao, in March, 1960, include a few specimens of mammals. As was the case with the Indian site Santa Cruz, on Aruba (HOOIJER, 1960), several forms are represented that are no longer extant on the island, although this does not imply that all of them were strictly endemic at the time of formation of the Indian refuse heaps; they may have been imported for food or other purposes. The material dates from 1000—1500 A.D., and is therefore late pre-Columbian. The following forms are present: |

| Mr. H. R. VAN HEEKEREN and Mr. C. J. DU RY, of the Rijksmuseum voor Volkenkunde at Leiden, entrusted me with the identification of some animal remains collected from Indian sites on Aruba by Professor J. P. B. DE JOSSELIN DE JONG in 1923. These remains relate for the most part to marine turtles (Chelonia mydas L. and Caretta caretta (L.)), indistinguishable from the recent forms today living in the Caribbean Sea, but they do include also a small number of bones of mammals. These comprise a few items which are of sufficient interest to make it worth while placing the specimens on record. Five species of mammals are represented, three of which do not belong to the extant fauna of Aruba. The annotated list is given below. Details on the localities of Santa... |
