A Harbour Porpoise, Phocoena phocoena, taken from near Shallow Bay, Mackenzie River Delta, Northwest Territories (68°48’ N 136°35’ W) in July 1973 represents a range extension 800 km eastwards from the previous extreme northeastern record on the north Alaskan coast. All 12 Harbour Porpoises so far examined from either the extreme north of the range of the species in the eastern North Pacific Ocean, or from the extreme south of the range in the eastern North Pacific and eastern North Atlantic Oceans, are large animals.

Bree, P.J.H. van; Bosscha Erdbrink, D.P..

The fortuitous discovery, in the collections of the National Museum of Natural History at Leiden, of a probably subfossil right half-mandible of a Grey Seal is reported. A short description of the piece is given and it is compared with some other recent, subfossil and fossil material.

Anomalies in the dentition of the Fox, Vulpes vulpes (Linnaeus, 1758), from continental western Europe

Bree, P.J.H. van; Sinkeldam, E.J..

While studying skulls of Foxes from western Europe for taxonomical purposes, the authors were struck by the high percentage of skulls not showing the normal tooth-formula. However, after a literature survey, it became clear this phenomenon is not rare in Canidae (Colyer, 1936; Hall, 1940; Reinwaldt, 1963, and Fleischer, 1967). But the occurrence of anomalies in the dentition may vary geographically and as such may have taxonomical significance (e.g., in Talpa europaea; see Stein, 1963). Thus it was thought useful to publish our data. Our notes concern samples from three different populations, viz., from the Netherlands, from western France (roughly the area between Rennes and Bordeaux) and from southern France (southeastern slopes of the Cevennes). For the...

Catalogue of the remains of Pinnipedia (Mammalia) in the collection of the Institute of Taxonomic Zoology (Zoological Museum Amsterdam)

Ano: 1969

URL: http://www.repository.naturalis.nl/record/504132

As is usual in university museums, the Zoological Museum of the University of Amsterdam (now Institute of Taxonomic Zoology) had in its collection some representative material of Pinnipedia. Some mounted specimens, some mounted skeletons, a few skulls (mainly from animals, which died in the Amsterdam Zoological Garden “Natura Artis Magistra”, commonly named Artis) and a few flat skins. A growing interest in marine mammals in general, the enthousiastic collecting activity of the late Mr Erik Flipse (a biology student, who sadly was killed at a hold-up in Afghanistan in 1979) and the seal research programme of the Research Institute for Nature Management headed by Dr J.L. van Haaften in the early years of the last decade, enlarged the collection...

Deux exemples d’application des critères d’âge chez la Loutre, Lutra lutra (Linnaeus, 1758)

Ano: 1992

URL: http://www.repository.naturalis.nl/record/505550

A collection of skulls of the Common Otter from western France was studied and compared with skulls of the same species from Denmark and the Netherlands. No significant differences were found. Age and sex composition of the three collections are given. Lutra lutra angustifrons Lataste, 1885, was based on comparison of the skull of a fullgrown Otter from Algeria with the skull of a juvenile Otter from France. Most probably this subspecies (syn. Lutra lutra splendida Cabrera, 1906) does not differ from the nominate subspecies.

Evolution and the pathology of deep diving in the Bottlenosed Dolphin, Tursiops truncatus (Montagu, 1821) (Notes on Cetacea, Delphinoidea V)

Ano: 1968

URL: http://www.repository.naturalis.nl/record/504994

Purves, P.E.; Bree, P.J.H. van.

Cadenat (1959) and Rancurel (1964) produced strong indirect evidence that off the west coast of Africa, the Bottle-nosed Dolphin, Tursiops truncatus, is in the habit of diving very deeply, possibly down to 600 m. Examination of the skulls of fully adult specimens of Tursiops taken off Dakar and St. Helena revealed marked distension and fenestration of bones associated with the accessory air sinuses of the middle ear. The condition suggests a pathological enhancement of the normal processes of evolution of these bones in order to adjust to excessive middle ear pressure sustained intermittently over a long period.

Fossil appendicular skeletal walrus material from the North Sea and the estuary of the Schelde (Mammalia, Carnivora)

Ano: 1972

URL: http://www.repository.naturalis.nl/record/504799

Seventeen fossil, and two recent odobenid remains belonging anatomically to the appendicular skeleton, encountered by us in two public and two private collections since the publication of a number of earlier papers, are described and discussed. Most specimens should be identified as Odobenus rosmarus or simply as Odobenus sp., but in some cases identification as either Odobenus antverpiensis (Rutten, 1907) or as Odobenus huxleyi (Lankester, 1865) appears to be justified.

Fossil axial skeletal walrus material from the North Sea and the estuary of the Schelde, and a fossil Sirenian rib (Mammalia, Carnivora; Sirenia)

Ano: 1999

URL: http://www.repository.naturalis.nl/record/504779

Ten fossil odobenid remains, and a fossil sirenian rib, encountered by us in a public and in a private collection since the publication of some earlier papers, are described and discussed. All fossils belong, anatomically, to the axial skeleton. Most specimens can be identified as Odobenus rosmarus, but in some cases determination as O. antverpiensis (Rutten,1907) may be possible.

Fossil cranial walrus material from the North Sea and the estuary of the Schelde (Mammalia, Carnivora)

Six cranial odobenid remains in a public collection, which have come to our notice since the publication of two earlier papers, are described and discussed. Identification of several specimens with Odobenus antverpiensis (Rutten, 1907) cannot be ruled out.

Fossil Odobenidae in some Dutch collections (Mammalia, Carnivora)

Ano: 1999

URL: http://www.repository.naturalis.nl/record/505041

Eight cranial and five postcranial fossil specimens are described and identified as remains of Odobenidae. Two of these (one, from Rhenen, certainly, and the other tentatively) are ascribed to the fossil, Early Pleistocene Odobenus huxleyi (Lankester, 1865), the others to the recent form, O. rosmarus (L.), while it appears possible to ascribe two of these even to the Adantic subspecies rosmarus. Some critical remarks are made regarding the systematic value of the genera Trichecodon and Alachtherium and the species antverpiensis (Rutten, 1907). The latter may eventually prove to be identical with huxleyi.

Fossil Phocidae in some Dutch collections (Mammalia, Carnivora)

Ano: 1986

URL: http://www.repository.naturalis.nl/record/504965

Bree, P.J.H. van; Bosscha Erdbrink, D.P..

Three cranial and seventy postcranial fossils are briefly described and identified as remains of Phocidae. Three of these are ascribed to the Bearded Seal Erignathus barbatus (Erxleben, 1777), nineteen to the Grey or Atlantic Seal Halichoerus grypus (Fabricius, 1791), and the remainder to the Common or Harbour Seal Phoca vitulina (Linnaeus, 1758). Five specimens were collected on the Meuse levels, an artificial plain South of the Hook of Holland formed from sand sucked up at the locality. All other material comes from the North Sea bottom and was found by fishermen trawling for flat-fish.

Further observations on fossil and subfossil Odobenid material (Mammalia, Carnivora) from the North Sea

Ano: 1987

URL: http://www.repository.naturalis.nl/record/505006

Six cranial and two postcranial fossil and subfossil odobenid remains that have come to our notice since our 1986 paper on the same subject are described and discussed. One of these can, with some confidence, be identified as Odobenus antverpiensis (Rutten, 1907). The others either belong to the recent species, Odobenus rosmarus (Linnaeus, 1758), or should simply be identified as Odobenus species. Some remarks are made on the morphological differences between antverpiensis (perhaps identical with huxleyi) and rosmarus.

The author measured length and breadth (in tenths of millimeters) of 855 Gull eggs from a large colony on the island of Texel (Eendracht). Frequency curves of length (fig. 1) and breadth (fig. 2) are given, as well as the curves on probability paper (fig. 3). Fig. 4 shows the distribution of the respective relations between length and breadth; the data given by de Vries, Jourdain, and Bau have been added.

Neophocaena phocaenoides asiaeorientalis (Pilleri & Gihr, 1973), a synonym of the preoccupied name Delphinus melas Schlegel, 1841 (Notes on Cetacea, Delphinoidea VII)

Ano: 1952

URL: http://www.repository.naturalis.nl/record/505241

The name Delphinus melas, given by Schlegel (1841) to a Finless Porpoise from Japan, is a junior homonym of Delphinus melas Traill, 1809 (now: Globicephala melaena). The generic name Neomeris Gray, 1846 is preoccupied by Neomeris Costa, 1844; the valid nomen novum for Gray’s genus is Neophocaena Palmer, 1899. Neomeris asiaeorientalis Pilleri & Gihr, 1973 belongs to the same taxon as described by Schlegel. Therefore the correct name of the Japanese form described by Schlegel is Neophocaena phocaenoides asiaeorientalis (Pilleri & Gihr, 1973).

Notes on some specimens of the genus Plecotus Geoffroy, 1818 (Mammalia, Chiroptera) from the Netherlands

Bree, P.J.H. van; Dulić, B..

In 1912, MILLER united all the West European bats with very long ears joined across the forehead and with 36 teeth into one species, Plecotus auritus (LINNAEUS, 1758). By doing so he followed BLASIUS (1857), DOBSON (1878) and TROUESSART (1910). This situation, one species without subspecies, remained till 1940. In that year V. & E. MARTINO described a subspecies of the Long-eared Bat, Plecotus auritus meridionalis, based on animals from Slovenia, Yugoslavia. The animals were characterized by having larger skulls than the bats in Northern Europe. In 1957, BAUER studied a collection of bats from Spain. He described a new subspecies, Plecotus auritus hispanicus, on bats from the surroundings of Linares de Riofrio, Salamanca. The bullae auditori of the...

On a Luxation of the skull-atlas joint and consecutive ankylosis in a Grey Seal, Halichoerus grypus (Fabricius, 1791), with notes on other Grey Seals from the Netherlands

Ano: 1963

URL: http://www.repository.naturalis.nl/record/504876

On January 3, 1969, about 1 km south of Zandvoort, Netherlands, a very young female Grey Seal was found on the beach. The animal was exhausted and in a bad condition and could therefore be caught. It was taken to the Amsterdam Zoo where, in spite of good care, it died on February 17 of the same year. While living in the Zoo it was noted that the seal from time to time had convulsions, that it was partially lame, and that its head was positioned in a rather unusual manner. After its death, the Grey Seal was brought to the Zoological Museum of the Amsterdam University for dissection. During the dissection and more clearly afterwards when the whole skeleton was cleaned, a luxation of the skull-atlas joint and a consecutive ankylosis was observed (see plate...

L’examen d’un crâne, dont les mensurations et les dessins sont donnés dans cet article, trouvé à Niodor, Iles du Saloum, République du Sénégal, en 1966, a permis d’identifier un Peponocephala electra (Gray, 1846). Cette espèce, assez mal connue, a été trouvée seulement une ou deux fois dans l’Océan Atlantique.

On extralimital records of arctic seals (Mammalia, Pinnipedia) on the Westeuropean continental coast in the past and at present – a summary

Ano: 1968

URL: http://www.repository.naturalis.nl/record/504836

In the past extralimital finds of arctic seals on the Westeuropean continental coast (northern Denmark to southern Spain) were rarely recorded. At present much more cases are known. According to the author this is due to more naturalists visiting the coasts, more and better identification manuals, the creation of seal rehabilitation centres where ill and abandoned baby seals were brought to and yearly published lists of marine mammals found on the coasts. The last two developments gave rise to networks of interested collaborators and thus to increased awareness.

Within the genus Globicephala Lesson, 1828, only two species can be recognized, namely: Globicephala melaena (Traill, 1809) and Globicephala macrorhynchus Gray, 1846. Globicephala sieboldii Gray, 1846, is a synonym of G. macrorhynchus. Synonymies of the two species as well as a key to both species are given. Whether Globicephala melaena has an antitropical distribution in the Pacific as in the Atlantic is not yet known.
