| A new ostracod found in the Mississippian of the Cantabrian Mountains shows ornamental features similar to Criboconcha Cooper, hitherto known from Mississippian and Pennsylvanian strata of different parts of the world (especially from the U.S.A.). However, some features of this ostracod are very different from the typical characteristcs of the Healdiidae and support bairdiocyproidean affinities. The new genus Pseudocriboconcha (type species Pseudocriboconcha prinsi sp. nov.) is proposed. This species is distinguishedby distinct pits on the lateral surface; a posterior ridge ending in dorsal and ventral spines; a rounded rim parallel to the borders of each valve; and a spine on this rim, above the anterior end and directed dorsally or anterodorsally. |

| The stratigraphic positions of the Wadi Dukhan and Al Uwayliah formations are reviewed. Diagnostic Maastrichtian larger foraminiferal species from the Wadi Dukhan Formation in well B7 – 41 (Cyrenaica) and in well U2 – 6 (northeastern Sirt Basin) are illustrated for the first time. These species are Omphalocyclus macroporus (Lamarck), Siderolites cf. calcitrapoides Lamarck and Orbitoides cf. media (d’Archiac). Following the rules of nomenclature, the type section of the Al Uwayliah Formation should be considered a composite stratotype. The section east of al Uwayliah village is the holostratotype (upper part of the formation) and the Jardas al Jarrari section is the parastratotype (lower part of the formation). The combined thickness of the two component... |

| The specific diversity of fossil crinoids from the Much Wenlock Limestone Formation at Dudley, Worcestershire, and in Shropshire differ by an order of magnitude. The latter are relatively depauperate and include only about six nominal species. Over 165 years ago, a specimen from Coalbrookdale, Shropshire, was identified as Cyathocrinites tuberculatus Miller (= the taxocrinid flexible Protaxocrinus tuberculatus (Miller)). This specimen, although indifferently preserved, is distinct from other Silurian crinoids of the British Isles and is described herein as a monobathrid camerate, Macrostylocrinus? jefferiesi sp. nov. This species has a moderately large, conical dorsal cup with at least 20 arms, broad primibrachials, a granular surface sculpture and no ray... |

| A partir de l'étude des Cricetidae de Vieux-Collonges (Rhône, France) les auteurs sont arrivés à une nouvelle conception de la systématique des Cricetidae tertiaires de l'Europe. Les principaux changements sont les suivants: Le genre Democricetodon est rangé parmi les Cricetinae, et non plus parmi les Cricetodontinae. Pour les hamsters oligocènes les nouvelles sous-familles Eucricetodontinae et Paracricetodontinae sont érigées. Les Cricetodontinae dans leur nouveau sens restreint sont subdivisés en plusieurs tribus. Le genre Cricetodon est subdivisé en quelques sous-genres nouveaux. |

| A number of species of Drupinae, all quite unusual faunal elements, which up to now have been assigned to such genera as Taurasia, apparently confined to the South European Miocene, or Preangeria, Acantinella and Acanthinucella of the Southeast Asian Miocene are reconsidered. On the basis of their unique columellar features it is presently proposed to unite Acantinella, Preangeria and Taurasia, the last name taking priority. Two new species are described: Taurasia niasensis and T. pendopoensis, from Indonesian Plio-Pleistocene and Miocene, respectively. A living Indo-Western Pacific species, called Purpura buccinea since 1844, is reclassified as presumably the only representative of Taurasia in the Recent fauna known to date. |

| 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... |

| A lectotype has been assigned for Placosmilia? robusta Umbgrove, 1925. This taxon, although fitting into the original diagnosis of Placosmilia, is not defined by the emended diagnosis of Alloiteau and later authors. Specimens from the Upper Maastrichtian of The Netherlands, that were formerly wrongly attributed to Galaxea fasciculata (Lamarck, 1816), a homonym of the extant species Galaxea fascicularis (Linnaeus, 1758), belong to Placocoenia macrophthalma (Goldfuss, 1826). The specimen depicted as P. macrophthalma by Umbgrove does not belong to this taxon and is placed in open nomenclature. |

| Over two hundred bones from the Upper Miocene of Gargano are recognized as belonging to 13 different species of birds. All of them are land birds representing four orders: Falconiformes (5 species), Galliformes (1), Strigiformes (6), Passeriformes (1). One new genus (Garganoaetus) and four new species are described. Among the birds of prey Garganoaetus freudenthali nov. sp. is an eagle of great size, and Tyto gigantea nov. sp. an owl of gigantic dimensions, comparatively speaking. |

| In April 1961 the present author made a study of the fossil Carnivora from Java in the Dubois Collection, of the Rijksmuseum van Natuurlijke Historie, Leiden. Among a lot of unidentified specimens, one was found to represent a sabre-toothed cat of a type not hitherto known from the Pleistocene of Java. The only sabre-tooth so far known from the Pleistocene of Java is Homotherium zwierzyckii (Koenigswald), which occurs in the Djetis fauna. The new form is certainly not a Homotherium, and may be identified as a member of the genus Megantereon. Thus it can be shown that both of the characteristic Pleistocene Old World forms of machairodont cats were represented in Java. Though the genus Megantereon does not survive in post-Villafranchian times in Europe, as... |

| In this paper, a revision of the Pliocene and Quaternary Lutrinae from Europe is presented. Such a revision, including fossil material, has not been published since the work of Pohle (1919). Three tribes within the Lutrinae are recognized: the Lutrini, the Aonyxini and the Enhydrini. The latter comprises both Enhydra and the Enhydriodon group. The genus Nesolutra, consisting of three insular species, is not retained. Two are included in Lutra and for N. ichnusae a new genus, Sardolutra, is proposed. The genus Isolalutra is not retained either. Its only species, I. cretensis, is included in the genus Lutrogale. Some new material of this species is described. A number of well-preserved fossils of Cyrnaonyx antiqua are described, such as the hitherto unknown... |

| Fossil and extant suids from Indonesia, ranging in age from Pliocene? to Recent, are revised. All material is ascribed to the genus Sus, except two species found on Sulawesi (Celebes) which belong to Babyrousa and Celebochoerus, respectively. From the ten Recent species and subspecies recognised, one from the Island of Flores - Sus heureni - is described as new. The Recent species are compared with the fossil ones on the basis of the same morphological characters. As a result uniformity is achieved in the classification of the extant and fossil suids. Based on this classification, the phylogeny, evolution and biostratigraphy of the various Javanese species of the genus Sus are discussed. |

| Ostracodes are reported for the first time from epimetamorphic, strongly tectonized Triassic rock sequences from the internal part of the Betic Cordilleras. Three ostracode-zones have been established. The lower and middle zones are attributed to the Late Ladinian (Longobardian) and the upper zone to the Early Carnian (Cordevolian). Several new species and subspecies are described (Acratina muelleri, Judahella pulchra posterospinosa, Falloticythere mulderae, F. rondeeli, Lutkevichinella? egeleri, Mostlerella blumenthali blumenthali, M. b. minuta, Leviella sohni) and a new genus (Falloticythere). The microfaunas — and especially the ostracodes — appear to be very helpful for a precise dating of the Triassic sequences in the Betic Zone. This has allowed... |
