A sirenian skeleton from the Miocene of Eibergen, province of Gelderland, The Netherlands: Metaxytherium cf. medium Desmarest
Provedor de dados: 16
Autores: Hooijer, D.A.
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...

Phocanella minor van Beneden, een kleine fossiele zeehond : nieuw voor de zwarte bottenfauna van de Schelde
Provedor de dados: 16
Autores: Hooijer, D.A.
In 1876 beschreef Van Beneden (1876: 799) resten van een kleine zeehond uit het Scaldisien van het Bekken van Antwerpen als Phocanella minor. Newton (1891: 19/20) meldde een humerus fragment van deze soort afkomstig uit het Nodule Bed van de Red Crag bij Foxhall, 4 mijl Z.W. van Woodbridge in Suffolk. Een fragment van een femur werd door Van Deinse (1927: 1363) gerapporteerd van de Groeve van Wiegerink ten noorden van Zwolle; dit zou tot nu toe de enige fossiele vondst van Phocanella minor uit ons land zijn. Het zwarte botje waarvan hier nu melding wordt gemaakt ontving ik van Dr. P. H. de Buisonjé en is afkomstig van een schelpenzuiger in de Westerschelde. Het is een groot deel van het heiligbeen (sacrum), en de overeenkomst met het sacrum van Phocanella...

Pleistocene vertebrates from Celebes : XI. Molars and a tusked mandible of Archidiskodon celebensis Hooijer
Provedor de dados: 16
Autores: Hooijer, D.A.
The species mentioned in the title of the present contribution was first described on the base of two incomplete upper molars, some fragments, and two portions of limb bones (Hooijer, 1949). The two and only complete molars were described later (Hooijer, 1953a). To this has been added the description of the milk dentition and of three premolars (Hooijer, 1953c). There are, however, important lacunae in our knowledge of the molar dentition to be filled. It remains as yet uncertain whether the type upper molar of 1949 represents M2 or M3, while the smaller of the complete lower molars of 1953 could be either M1 or M2. The prolonged study of the fragmentary molars in the Celebes collection has now made it possible to assemble the full set of upper and lower...

On fossil and prehistoric remains of Tapirus from Java, Sumatra and China
Provedor de dados: 16
Autores: Hooijer, D.A.
The tapir is an extremely rare element in the fossil Mammalian fauna of Java. In the enormous collection of fossil teeth and bones brought together in this island by Eug. Dubois in the years 1890 to 1900, the tapir is represented only by six teeth, originating from three localities in the Kendeng Mts., viz., Kedoeng Broeboes, Kedoeng Loemboe, and Kebon Doeren. Previous to his researches in Java, Dubois collected teeth in a number of caves in the Padang Highlands. In this Sumatran collection Tapirus is not uncommon. We possess one hundred and twenty complete, and a still larger number of broken teeth. Half of this collection originates from three caves, viz., the Lida Ajer cave near Pajakombo, the Sibrambang cave, and the Djamboe cave near Tapisello. The...

Varanus (Reptilia, Sauria) from the Pleistocene of Timor
Provedor de dados: 16
Autores: Hooijer, D.A.
The present note deals with two varanid vertebrae from Pleistocene gravel deposits at Raebia in the Atambua area of Indonesian Timor. The specimens were collected in 1966 by Dr. Th. Verhoeven, who gave them to me for study. Other fossil vertebrate remains from the same site belong to a giant land tortoise, Geochelone atlas (Falconer &amp; Cautley) also known from the Pleistocene of India, Java and the Celebes (Hooijer, 1971), and Stegodon timorensis Sartono, a pygmy proboscidean comparable to those of the Pleistocene of the Celebes and Flores (Hooijer, 1972). No further remains of the varanid have been discovered, and the vertebrae may here be placed on record. There are a thoracic vertebra, with the neural spine broken off and the condyle as well as the...

Pleistocene vertebrates from Celebes : XII. Notes on pygmy stegodonts
Provedor de dados: 16
Autores: Hooijer, D.A.
There is a reason for adding to the series "Pleistocene vertebrates from Celebes", which was brought to a conclusion just a decade ago, and which has since been summarized, with bibliographic references, e.g., in Van Heekeren (1957) and Hooijer (1959, 1960). The discovery of a pygmy stegodont in the island of Flores, Lesser Sunda Islands (Hooijer, 1964) brought me to a reconsideration of the evidence for a pygmy Stegodon in Celebes, which was considered inconclusive at the time, and restudy of all the fragmentary specimens in the Celebes collection not included in the published reports. As a result, all doubt concerning its status is removed; the Celebes Stegodon is decidedly smaller than Stegodon trigonocephalus Martin from Java. The evidence will be...

Three new giant prehistoric rats from Flores, Lesser Sunda Islands
Provedor de dados: 16
Autores: Hooijer, D.A.
The specimens described in the present paper have been collected by Dr. Th. L. Verhoeven at Liang Toge, a cave near Warukia, 1 km south of a hamlet called Lepa, in Manggarai, western Flores. This cave, as well as many others explored in the island by Verhoeven (1952, 1953), contains a Mesolithic flake and blade industry (Van Heekeren, 1957, p. 107). The faunal remains obtained from Liang Toge consist almost exclusively of jaws and bones of large rats, and it is of interest to place these specimens on record as they represent forms that are new to science, different from the one and only giant rat that is still living on Flores, Papagomys armandvillei Jentink). The discovery of new giant rats in a comparatively recent cave deposit such as that of Liang Toge...

Additional Miocene to Pleistocene rhinoceroses of Africa
Provedor de dados: 16
Autores: Hooijer, D.A.
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...

Pleistocene vertebrates from Celebes : XIV. Additions to the Archidiskodon-Celebochoerus fauna
Provedor de dados: 16
Autores: Hooijer, D.A.
A joint Dutch-Indonesian expedition to Celebes in 1970 worked especially in the Beru area whence the first described Pleistocene Celebes vertebrate remains came. In the present contribution I shall describe the most important specimens that have been brought to light. My thanks are due to Mr. R. P. Soejono for permission to take certain specimens with me to the Netherlands for study and comparison. The expedition was financed by the Netherlands Foundation for the Advancement of Tropical Research (Wotro) at The Hague. No further remains of Elasmobranchii (sharks and sting rays: Hooijer, 1954b) were found at Sompoh, so there are no additions on that score. Of the giant land tortoise, originally described as Testudo margae Hooijer (1948), an abundance of...

Note on subfossil teeth of Equus zebra L. from Orange free State
Provedor de dados: 16
Autores: Hooijer, D.A.
Some time ago Dr. L. D. Brongersma, curator of the Leiden Museum, entrusted me for examination some subfossil equine teeth, received from Mr. H. van Hoepen, who had found them between Glen and Mazelspoort, in Orange Free State. The teeth proved to belong all to one and the same individual, and to constitute the entire upper premolar-molar-series of the right side, almost undamaged. The importance of this find is evident, as most of the fossil or subfossil equine species from S. Africa are based on isolated teeth. An inner view of our specimen is given in pl. VI lower figure, the crown surfaces are represented in the upper figure of the same plate. It can be seen, that the P4 is the longest tooth, its height is 72 mm. The mesostyle is prominent, and...

Dental anomaly in Tapirus terrestris (L.)
Provedor de dados: 16
Autores: Hooijer, D.A.
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).

Mammalian remains from an Indian site on Curaçao
Provedor de dados: 16
Autores: Hooijer, D.A.
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:

Hipparions of the Laetolil Beds, Tanzania
Provedor de dados: 16
Autores: Hooijer, D.A.
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 valid name of the Banteng: Bibos javanicus (d'Alton)
Provedor de dados: 16
Autores: Hooijer, D.A.
While studying the collection of recent oxen of the Museum my attention was drawn to the problem of the nomenclature of the Java banteng. I believe to have been able to clear up the confusion that still exists today, as will be set forth in the present note. The wild ox of Java, the banteng, is known variously as Bos sondaicus or Bos banteng, but neither of these is the earliest available valid name. The species should have been called: Bibos javanicus (d'Alton) B[os] Javanicus d'Alton, Skelete der Wiederkäuer, Bonn, 1823, p. (7), pl. VIII fig. c. The earliest reference to the banteng of Java I have been able to find is in Pennant (1800, p. 35): "Mr. Loten told me that wild oxen, of a reddish brown color, with vast horns, and of a great size, are found in...

Hipparions from the late Miocene and Pliocene of Northwestern Kenya
Provedor de dados: 16
Autores: Hooijer, D.A.; Maglio, V.J.
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 &amp; 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...

A further Note on the Canines of Celebochoerus
Provedor de dados: 16
Autores: Hooijer, D.A.
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...

Some remarks on recent, prehistoric, and fossil Porcupines from the Malay Archipelago
Provedor de dados: 16
Autores: Hooijer, D.A.
Few fossil remains of rodents have been collected in Java until now, and they have received little attention. In the reports published during his paleontological researches in Java, Dubois twice records finds of Hystrix remains, viz., at Pati-Ajam in Japara (Anonymus, 1891, p. 12/13), and in the region between Bangle and Djeroek (Anonymus, 1893, p. 12). In a subsequent paper (Dubois, 1907, p. 454) we find mention of the presence of porcupines in the fossil fauna of Java, but in his review of the latter fauna Dubois (1908) bestows no words upon these rodents. The Selenka Expedition to Trinil secured one tooth, which was figured by Stremme (1911, p. 83, pl. XVI fig. 5) as a right M2 of a small species of Hystrix. Finally a tooth of Hystrix from Sangiran II...

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.

Shungura Members G, H, J, Κ and L, and the Kalam Outcrop, have yielded teeth and some postcranial elements assignable to Equus oldowayensis Hopwood, 1937. Member G (earliest Early Pleistocene) has yielded a sample of 21 upper and nine lower teeth and two complete and one partial metapodials. Member Κ (middle to late Early Pleistocene) has yielded nine upper and four lower teeth. The other members have yielded smaller samples. Positive identification of the species from Members G, K, and the Kalam Outcrop are based on series of associated teeth derived from single individuals. The recognition of E. oldowayensis from Shungura Members G-L corresponds to its known temporal range through Bed I at Olduvai Gorge and its existence in East Africa throughout the...

The fossil elephant remains recently discovered in S. Celebes by Mr. H. R. van Heekeren, and entrusted to me by Prof. Dr. A. J. Bernet Kempers, Head of the Archaeological Survey of the Dutch East Indies, belong to a small form of the genus Archidiskodon. These specimens, described and figured in the present paper, give the first evidence of the existence of Proboscidea in the island of Celebes. As stated already in earlier notes on the fossils in Mr. Van Heekeren's collection (Hooijer, 1948a, 1948b, 1948c) this elephant is associated with a fauna containing a peculiar suid (Celebochoerus heekereni Hooijer), a babirusa (Babyrousa babyrussa beruensis Hooijer), an anoa (Anoa depressicornis (Smith) subsp.), and a gigantic land-tortoise (Testudo margae...

INTRODUCTION The fossil remains of Hippopotamus from the Pleistocene "Elandsfontein" site near Hopefield, Cape Province, have already been briefly described by Singer and Keen (1955), who found that the material available at the time was not different from the living Hippopotamus amphibius L. However, it seems worthwhile to review their status since the Hippopotamus material has been considerably increased as a result of recent collecting trips to the site. Not only are there now cranial remains, but also postcranial material, notably carpals, tarsals and metapodials. The purpose of the present note is to place on record all the material at present in the Hopefield collection pertaining to the species in question. The specimens, originally housed in the...

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...

Some remarks on the subspecies of Phalanger ursinus (Temminck) and of Lenomys meyeri (Jentink) from Celebes
Provedor de dados: 16
Autores: Hooijer, D.A.
In connection with a study of an extensive collection of prehistoric mammals from Toalian caves in Southwestern Celebes, a certain number of recent mammal species from Celebes and adjacent islands have been examined. In most cases the recent material for comparison available of a given species was adequate to determine the status of the corresponding cave form. Some of the cave animals (Phalanger celebensis (Gray), Macaca maura (Geoffr. et F. Cuvier), Macrogalidia musschenbroekii (Schlegel), Sus celebensis Müller et Schlegel, and Babyrousa babyrussa (L.)) could be shown to be subspecifically distinct from the living forms (Hooijer, 1950 a). In all of these cases the time that has elapsed since the deposition of the material in the prehistoric caves has...

New records of mammals from the middle pleistocene of Sangiran, central Java
Provedor de dados: 16
Autores: Hooijer, D.A.
Collections of fossil vertebrate remains from the Sangiran area in Java have recently been presented to the Rijksmuseum van Natuurlijke Historie by Mr. H. R. van Heekeren and by Mr. J. H. Houbolt. They form a most welcome addition to the Museum collection of fossil vertebrates made by Eugene Dubois in Java in the 189o's; Sangiran is a site known to but not collected at by Dubois. We are grateful to Messrs. Van Heekeren and Houbolt for their generous gift to the Museum; the more important specimens in the Sangiran collection will be the subject of the present note. The Sangiran dome (for the geology of the area see Van Es, 1931: 55-68, and Von Koenigswald, 1940: 26-39), situated approximately 12 km north of Solo (Soerakarta) between the Kali Brangkal and...

Fossil Rodents from Curaçao and Bonaire
Provedor de dados: 16
Autores: Hooijer, D.A.
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...

On the supposed hexaprotodont milk dentition in Hippopotamus amphibius L.
Provedor de dados: 16
Autores: Hooijer, D.A.
While studying the literature on recent and fossil Hippopotami it became evident to me that a number of authors ascribe a third milk incisor to Hippopotamus amphibius L. Consequently this species, as regards the milk dentition, should be "hexaprotodont" like the Pliocene and Pleistocene species of Hippopotamus from the Siwaliks of India, Burma and Java; and like H. pantanellii Joleaud (1920, p. 18) from Casino near Siena in Italy (vide Pantanelli, 1879, p. 318, pl. IV fig. 5). According to Major (1896, p. 978) young specimens of H. lemerlei Grandidier from Madagascar occasionally are hexaprotodont too. When dealing with Hippopotamus amphibius L. Blainville (1847, p. 32) made the following remarks: "Dans le très-jeune âge, il est certain qu'il y a trois...

Pleistocene vertebrates from Celebes : V. Lower molars of Archididiskodon celebense Hooijer
Provedor de dados: 16
Autores: Hooijer, D.A.
Since 1948 Mr. H. R. van Heekeren, then prehistorian to the Archaeological Survey of the Dutch East Indies, kept up an intermittent search for fossil teeth and bones that occur in association with Palaeolithic artifacts at Beru and Sompoh, near Tjabenge (Sopeng district), about 100 km Northeast of Macassar in Southwestern Celebes. These sites are now known to yield an interesting vertebrate fauna, presumably Pleistocene in age, the first found elements of which were described a few years ago (Hooijer, 1948, 1949). One of the most remarkable discoveries in the Tjabengè area made by Mr. Van Heekeren is a small elephantine that I have named Archidiskodon celebensis (Hooijer, 1949). It was based on an almost complete and unworn upper molar, and on a similar...

Pleistocene vertebrates from Celebes : VII. Milk molars and premolars of Archidiskodon celebensis Hooijer
Provedor de dados: 16
Autores: Hooijer, D.A.
Among the fossil proboscidean remains collected by Mr. H. R. van Heekeren in the Tjabengè area, Sopeng district, about 100 km Northeast of Macassar in Southwestern Celebes there are a number of very small teeth. They can be referred to the species of Archidiskodon of which I originally described two specimens of M2 or M3, some molar fragments, the distal end of an ulna, and the proximal end of a tibia (Hooijer, 1949), to which could later be added a fine M3, and an M1 or M2, both completely preserved (Hooijer, 1953a). Archidiskodon celebensis Hooijer is the smallest species of Archidiskodon known at present. Its molars are only one-half as large in linear dimensions as those of Archidiskodon planifrons (Falconer et Cautley), and they agree with the latter...

Archidiskodon planifrons (Falconer et Cautley) from the Tatrot zone of the Upper Siwaliks
Provedor de dados: 16
Autores: Hooijer, D.A.
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...

Trogontherium cuvieri Fischer from the Neede Clay (Mindel-Riss Interglacial) of the Netherlands
Provedor de dados: 16
Autores: Hooijer, D.A.
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).

Fossil rhinoceroses from Hopefield, South Africa
Provedor de dados: 16
Autores: Hooijer, D.A.; Singer, R.
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...

Elephas Celebensis (Hooijer) from the Pleistocene of Java
Provedor de dados: 16
Autores: Hooijer, D.A.
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...
