Bree, P.J.H. van; Gallagher, M.D..

Three recently found skulls of Delphinus tropicalis are discussed and compared with other skulls of the same taxon. The occurrence of Delphinus delphis in the same area as Delphinus tropicalis makes it plausible that D. tropicalis is a distinct species and not a subspecies of D. delphis. A dolphin collected in the South China Sea, probably near Pontianak, by W. L. Abbott in 1907 also belongs to Delphinus tropicalis. The species therefore has a wider distribution than was originally believed.

Orshoven, Jo van; Bree, P.J.H. van.

A collection of Megachiroptera captured in mistnets at Kankasili (10° 11' N, 12° 29' W), Republic of Guinea, Africa, during 1966—1967, is described. The following species were represented: Rousettus aegyptiacus (10 specimens), Lissonycteris angolensis (2 specimens), Epomophorus gambianus (1 specimen), Epomops buettikoferi (13 specimens), Micropteropus pusillus (104 specimens) and Nanonycteris veldkampi (4 specimens). Measurements, as well as descriptions of the colours and of the palatal ridges of the bats are given.

On the moult in the Stoat, Mustela erminea Linnaeus, 1758, from the Netherlands

Ano: 1968

Soest, R.W.M. van; Bree, P.J.H. van.

1. A detailed study was made of the subsequent stages in the colour change of the Stoat, Mustela erminea Linnaeus, 1758. 2. Starting and finishing date of both Autumn and Spring moult were determined, based on the examination of 300 pelts from the Netherlands. 3. An indication was found for the existence of a difference in finishing date of the Spring moult in male and female Stoats. The examinations showed that female Stoats complete their summercoat a good month earlier than males. 4. It appeared that there is a remarkable difference in number of completely white animals between warmer and colder parts in the Netherlands. The colder regions hold much more completely white animals. This indicates that temperature has an influence on whether Stoats turn...

On a skull of Peponocephala electra (Gray, 1846) (Cetacea, Globicephalinae) from Sénégal

Ano: 1969

Bree, P.J.H. van; Cadenat, J..

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 skulls of Stenella longirostris (Gray, 1828) from the eastern Atlantic (Notes on Cetacea, Delphinoidea IV)

Ano: 1968

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

Measurements of skulls of Stenella longirostris (Gray, 1828) from South Africa, the Ivory Coast, Liberia and Sénégal are published along with some other particulars. According to the author the dolphins from near the Goto Islands, Japan, described by Mizue et al. (1964) probably do not belong to some undescribed species but to Stenella longirostris.

On two skulls of Delphinus dussumieri Blanford, 1891 (Notes on Cetacea, Delphinoidea I)

Ano: 1971

URL: http://www.repository.naturalis.nl/record/504910

Two skulls of Delphinus dussumieri in the collections of the British Museum (Natural History) are discussed and their dimensions given. They represent the first ones known about 140 years after the description of the species, based on one skull from the Malabar Coast.

On three specimens of Lagenorhynchus albirostris Gray, 1846 (Mammalia, Cetacea)

Ano: 1971

Bree, P.J.H. van; Nijssen, H..

Recently the Zoological Museum in Amsterdam came into possession of three specimens of the White-beaked Dolphin, Lagenorhynchus albirostris. As data on this species are rather scarce, it may be useful to publish a few notes on these animals. The first dolphin, a female, was caught in the North Sea at 7.3 miles N.N.W. from IJmuiden (about 52° 34’ N, 4° 30’ E) at the end of November 1958 by a commercial fish-trawler. The animal was obtained by the Netherlands Whale Research Group T.N.O. (Prof. dr. E. J. Slijper and Drs. W. L. van Utrecht), Amsterdam, for anatomical studies. Afterwards the skull and the complete skeleton were presented to the Zoological Museum. The dolphin was pregnant, its fetus weighed 1.5 kg. This specimen bears the registration number ZMA...

On the dimensions of three skulls of the species of dolphin Lipotes vexillifer Miller, 1918 (Cetacea, Platanistoidea, Iniidae)

Ano: 1964

URL: http://www.repository.naturalis.nl/record/505163

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

The dimensions are given of three skulls of Lipotes vexillifer, the only specimens preserved in collections outside of China. At the same time drawings of the Lipotes vexillifer skull in the British Museum (Natural History) have been made and published with a photograph of the London specimen before it was dissected. Reasons are stated for refuting the affinity of Lipotes with Platanista, as postulated by Hinton & Pycraft (1922).

Short notes and reviews On a mounted skeleton of apparently the extinct Cape Lion, Panthera leo melanochaita (Ch. H. Smith, 1842)

Ano: 1975

URL: http://www.repository.naturalis.nl/record/504787

Recently, the skeleton of apparently a Cape Lion was discovered in the Zoological Museum of the University of Amsterdam. The history of the specimen as far as known is summarized and its attribution to Panthera leo melanochaita is elucidated with some measurements taken from the skeleton and the study of fur colours and manes’ development on an oil painting of the same animal in the Rijksmuseum Amsterdam. Both the animal and the painting once belonged to King Louis Napoleon Bonaparte of Holland.

On the taxonomic status of Delphinus pernettensis de Blainville, 1817 (Notes on Cetacea, Delphinoidea II)

Ano: 1998

According to the author insufficient proofs exist to consider Stenella plagiodon (Cope, 1866) a junior synonym of Delphinus pernettensis de Blainville, 1817 or of Delphinus pernettyi Desmarest, 1820. To avoid further confusion the International Commission on Zoological Nomenclature is requested to use their plenary powers to suppress for the purposes of the Law of Priority but not for those of the Law of Homonymy the following specific names: a. pernettensis de Blainville, 1817, as published in the combination Delphinus pernettensis; b. pernettyi Desmarest, 1820, as published in the combination Delphinus pernettyi.

On the presence of first premolars in skulls of badgers, MeleS meles (Linnaeus, 1758), mainly from the Netherlands

Ano: 1971

URL: http://www.repository.naturalis.nl/record/504897

Harmsen, B.J.; Bree, P.J.H. van.

The Eurasian badger (Meles meles) shows much variation in presence of first premolars. In this study a collection of badger skulls, mainly from the Netherlands, was examined for the presence of first premolar elements. The distribution pattern of first premolars, in skulls from the Netherlands, was compaired with data, presented in literature. Our results indicate that there are differences in distribution between different populations and that there might be differences between males and females in presence of first premolars. From a subset of 50 skulls, several measures were taken to see which factors are highly related with presence of first premolars. The amount of direct space for the first premolar to develop (distance between the canine and the...

Sex and age composition of a Stoat population (Mustela erminea Linnaeus, 1758) from a coastal dune region of the Netherlands

Soest, R.W.M. van; Bree, P.J.H. van.

The age composition of a sample of a Stoat population from the Netherlands was studied. Various relative age criteria were tested on their validity in separating age groups. The study of the layered cemental deposits contributed the most important part to the final conclusions. By using also the data on the sexual cycle of the Stoat, a theoretically expected age pyramid was calculated, which was compared with the actually found age composition.

Variations in length and breadth of eggs from a colony of black-headed gulls (Larus r. ridibundus Linnaeus) on the island of Texel

Ano: 1970

URL: http://www.repository.naturalis.nl/record/505124

An investigation was made in order to ascertain the mode of variation of length and breadth of eggs of the black-headed gull (Larus r. ridibundus) from a colony on the northeastern side of the island of Texel in the Netherlands. The colony can be divided into two ecologically different areas. A difference could be shown in the measurements of eggs collected in these areas. Two possible explanations of this coincidence are given. Methods of egg collecting and measuring are discussed, and data and tables of the findings during 1950, 1951 and 1952 are furnished. On account of the flood and disaster of 1953 the investigation was broken off before its completion. The fact that mean measurements and weights must be used with due caution is emphasized.

On Globicephala sieboldii Gray, 1846, and other species of Pilot Whales (Notes on Cetacea, Delphinoidea III)

Ano: 1957

URL: http://www.repository.naturalis.nl/record/505079

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.

On the remains of some Carnivora found in a prehistoric site at Vlaardingen, the Netherlands

Ano: 1971

URL: http://www.repository.naturalis.nl/record/504880

The excavation of a prehistoric site at Vlaardingen, about 10 km W. of Rotterdam, yielded among ceramics and other man-made objects, many remains of zoological origin (GLASBERGEN, 1960). Mr. P. J. VAN DER FEEN and Miss M. R. WALVIUS, who were in charge of the zoological material found at Vlaardingen, trusted the author with the identification of the remains of the Carnivora, with the exception of the remains of at least 5 Dog-like animals, which were sent to Prof. Dr. A. E. VAN GIFFEN at Groningen. The prehistoric settlement at Vlaardingen is provisionally dated as between 2300 and 2100 B.C. The settlement was situated along the border of a creek or river, which later on silted up. The bank on which the habitation level was found, was rather low and the...

Skrjabingylus nasicola (Nematoda) in skulls of Mustela erminea and Mustela nivalis (Mammalia) from the Netherlands

Ano: 1961

URL: http://www.repository.naturalis.nl/record/505071

Soest, R.W.M. van; Land, J. van der; Bree, P.J.H. van.

The occurrence of the skull parasite Skrjabingylus nasicola (Leuckart, 1842) in Stoats and Weasels from the Netherlands has been studied extensively. A redescription is given of certain morphological characters of the parasite, which includes the discovery of hitherto unknown peribuccal papillae. The genus Skrjabingylus is discussed. The extent of infection and the damage caused by the parasite in Stoats and Weasels has been assessed by studying collections of preserved skulls. Detailed comparisons are made between the infection percentages in both species of mustelids in different areas of the Netherlands and in different European countries. Also the relation between infection and age and sex has been studied. In the discussion an attempt is made to...

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

Ano: 1972

URL: http://www.repository.naturalis.nl/record/504864

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.

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

Ano: 1968

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

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).

On the correct Latin name of the Indus Susu (Cetacea, Platanistoidea)

Ano: 1973
