| Predation pressure, food availability, and activity may be affected by level of moonlight and climatic conditions. While many nocturnal mammals reduce activity at high lunar illumination to avoid predators (lunarphobia), most visually-oriented nocturnal primates and birds increase activity in bright nights (lunarphilia) to improve foraging efficiency. Similarly, weather conditions may influence activity level and foraging ability. We examined the response of Javan slow lorises (Nycticebus javanicus Geoffroy, 1812) to moonlight and temperature. We radio-tracked 12 animals in West Java, Indonesia, over 1.5 years, resulting in over 600 hours direct observations. We collected behavioural and environmental data including lunar illumination, number of human... |

| The Cerro de los Batallones (Los Batallones Butte) is located in the central-northern area of the Madrid Basin, central Spain. Nine vertebrates localities containing a large variety of mammals of Upper Vallesian Age (Late Miocene) have been found associated with the sediments forming the butte. From bottom to top, these sediments consist of magnesian lutite beds (Unit I), paleosols formed of sepiolite and opal (Unit II), and siliclastic, marlstone and carbonate beds (Unit III). The set of ERT profiles developed in Los Batallones Butte have demonstrate that electrical imaging techniques are an estimable tool for the characterization and prospecting of fossil sites developed in fine-grained siliciclastic sequences. These localities contain an exceptionally... |

| The insectivore assemblages from the Ramblian stratotype near Calamocha (Spain) are described, as well as those from San Roque 4A and 4B, two Ramblian localities near the Aragonian stratotype. Two new species are described, the erinaceid Galerix remmerti, and the shrew Clapasorex alvarezae. Both the percentages and the diversity of insectivores are higher in the Lower Ramblian, suggesting more humid conditions in zone Z than in zone A. This is in contradiction with the palaeoenvironmental reconstructions based on rodents. Se describen las asociaciones de insectívoros del estratotipo del Rambliense cerca de Calamocha (Teruel, España), junto de las de San Roque 4A y 4B, dos yacimientos Ramblienses del área-tipo del Aragoniense. Se describar dos especies... |

| 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... |

| INTRODUCTION The present paper contains notes on some recent cats in the collections of the Rijksmuseum van Natuurlijke Historie, Leiden, as well as descriptions of the fossil Felidae in the "Collectie Dubois", Leiden, which its Director Prof. Dubois entrusted to me. The fossils were collected in Java 1) by Prof. Eug. Dubois during his searches for remains of the precursor of man, and with the intention to gather data about the geological age and ecology of this precursor (cf. Dubois, 1888). The age of the deposits from which the fossil cats were collected, has been much discussed. A review of the literature (up to 1931) on this subject has been given by Van Es (1931), who concludes that the Trinilfauna must be referred to the lower plistocene age, while... |

| Reconstructing the body mass of a fossil animal is an essential step toward understanding its palaeoecological role. Length × width (L×W) of the first lower molar (m1) is frequently used as a proxy for body mass in fossil mammals. However, among rodents, Muroidea have no premolar and an elongated m1, whereas other groups have a premolar and a m1 that is not elongated. This leads to an overestimation of body mass in muroids and/or an underestimation in other rodents. To solve this problem we assembled data of upper and lower tooth row length and body mass in extant rodents, and calculated regression equations for all rodents, rodents with premolars, rodents without premolars and for taxonomic groups at superfamily or family level. Data for complete tooth... |

| The 19th-century reports on the occurrence and identity of wild asses in North-East Africa are reviewed, as well as the names applied in various publications by Fitzinger and von Heuglin, respectively. The first published name for the African wild ass, Asinus africanus Fitzinger, 1858, is a nomen nudum. The name Equus taeniopus von Heuglin, 1861 is rejected as indeterminable, as it is based on an animal that cannot be identified and may have been a hybrid between a domestic donkey and a Somali wild ass; the type has not been preserved. The first available name thus becomes Asinus africanus von Heuglin & Fitzinger, 1866. A lectotype is designated: a skull of an adult female collected by von Heuglin near Atbara River, Sudan, and present in the Museum für... |

| 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... |

| The presence of Galerix molars in the South German fossil locality Hammerschmiede 3 is interpreted as evidence for a reimmigration of West European origin into the North Alpine Foreland Basin at the transition of the Middle to Late Miocene. The brief re-appearence of Galerix in southern Germany can be used as a biostratigraphic marker that allows promising correlations between local biostratigraphic subdivisions from Spain and Germany, suggesting that, contrary to previous thought, the Hammerschmiede locality may antedate the hipparionine horses’ appearance event. Based on the supposed climatic adaptation of galericine taxa and lower vertebrate record, it is hypothesized that short term climatic fluctuations occurred in South Germany around the time of the... |

| An investigation was made into the systematics of white-toothed shrews (Crocidura) occurring in Malaya and Indonesia. Most of the forms recorded from this area have been found to represent one of four species: C. fuliginosa (Blyth, 1855), C. attenuata Milne-Edwards, 1872, C. maxi Sody, 1936 or C. monticola Peters, 1870, while the status of a few others remains unresolved at this stage. Each species is discussed and distinguishing features are given in tabular form. |

| Changes in the nomenclature of the Orang Utan recently proposed by Röhrer-Ertl are shown to be unnecessary. The generic name Pongo Van Wurmb, 1784, for the genus, P.s. satyrus Linnaeus, 1758, for the Sumatran subspecies, and P.s. borneensis Van Wurmb, 1784, for the Bornean subspecies, as used by Röhrer-Ertl all are invalid, and should be replaced by the correct traditional names, Pongo Lacépède, 1799, for the genus, P.p. pygmaeus (Linnaeus, 1760) for the Bornean subspecies, and P.p. abelii Lesson, 1827, for the Sumatran subspecies. |
