Cetaceans stranded in the Netherlands from 1998 to 2007 Naturalis
Camphuysen, C.J.; Smeenk, C.; Addink, M.; Jansen, O.E..
Between 1998 and 2007, 2063 cetaceans were found stranded in the Netherlands, representing at least 14 species. Two species, humpback whale (Megaptera novaeangliae) and Blainville’s beaked whale (Mesoplodon densirostris), are additions to the Dutch list. Apart from the first humpback whales, relatively many balaenopterid whales were found in comparison with previous decades. Range extension of recovering populations may explain part of this trend. However, the decline in strandings frequency in sperm whales (Physeter macrocephalus), another species with a slowly recovering Atlantic population but with a distinct peak in strandings in the 1990s, suggests that the factors underlying these changes are complex. During the 20th century, the strandings frequency...

Has one of Captain Cook’s possums landed in Leiden? The possible holotype of Pseudocheirus peregrinus (Boddaert, 1785) Naturalis
Smeenk, C..
The identity of an old female specimen of Pseudocheirus peregrinus (Boddaert, 1785) in the National Museum of Natural History, Leiden, is discussed and the early descriptions and nomenclatural history of the species are reviewed. The assumption by Temminck (1824) and Jentink (1888) that the animal originated from one of Cook’s expeditions is extensively considered, since in that case it would be the holotype of Didelphis peregrinus Boddaert, 1785 and of some objective synonyms. The documentation of the specimen is insufficient to draw a definitive conclusion. However, the damage to the facial skin of the animal collected at Endeavour River in 1770 mentioned by Pennant (1781) would agree with the state of the Leiden specimen, which must have been badly...

On the type material of Cervus Nippon Temminck, 1836: with a revision of Sika deer from the main Japanese Islands Naturalis
Groves, C.P.; Smeenk, C..
The type material of Cervus nippon Temminck, 1836, present in the Leiden museum, is re-examined ; a lectotype is chosen, and a new description of lectotype and paralectotypes is given. In an attempt to determine the exact type locality or localities, the type series is compared with published descriptions of Japanese Sika and with material present in the British Museum (Nat. Hist.). The characteristics of the type series are in good agreement with those of Sika from southern Japan; the lectotype closely agrees with specimens originating from the main islands of southern Japan (southern Honshu, Kyushu, Shikoku) and may have come from the surroundings of Nagasaki (Kyushu) ; the remaining type series agrees better with specimens from the Goto Islands, where...

On the type material of Mus argenteus Temminck, 1844 Naturalis
Smeenk, C.; Kaneko, Y.; Tsuchiya, K..
The taxonomic history of the Japanese Wood Mouse ("Himenezumi" in Japanese) is reviewed. Two scientific names have been widely used: Apodemus argenteus (Temminck, 1844) and Apodemus geisha (Thomas, 1905). To solve this controversy, the type material of Mus argenteus Temminck, 1844 in the Leiden museum is re-examined. The type series is composite; a lectotype is chosen. The lectotype corresponds in skull characters with the holotype of Micromys geisha Thomas, 1905; the latter name therefore is a junior synonym of Mus argenteus. The two paralectotypes are juvenile specimens of Apodemus speciosus (Temminck, 1844).

Opportunistic feeding behaviour of rough-toothed dolphins Steno bredanensis off Mauritania Naturalis
Addink, M.J.; Smeenk, C..
A small group of rough-toothed dolphins Steno bredanensis was observed at the outer edge of the Banc d’Arguin, Mauritania. The animals were feeding opportunistically around a trawling research vessel. Hunting behaviour and mother-calf interactions are described

Preliminary checklist of Cetacea in the Indonesian Archipelago and adjacent waters Naturalis
Rudolph, P.; Smeenk, C.; Leatherwood, S..
Records of 29 species of cetaceans from the Indonesian Archipelago have been gleaned from published and unpublished sources, representing five families: Phocoenidae (1 species), Delphinidae (16), Ziphiidae (3), Physeteridae (3), and Balaenopteridae (6). The presence of 26 species could be confirmed by material in museum collections, photographs or documentation by specialists. The occurrence of three species is still unconfirmed.

Stranding of sperm whales <i>Physeter macrocephalus</i> in the North Sea: history and patterns OMA
Smeenk, C..
Stranding of sperm whales <i>Physeter macrocephalus</i> L., 1758 in the countries bordering the North Sea has been documented since the end of the 16th century. All known strandings in this area are summarized. There is no clear temporal pattern in the occurrence of sperm whales in the North Sea except that there are very few strandings between the late 18th and early 20th century. All sperm whales of which details are known have been males, ranging from about 12 to 18 m in size. Most strandings occur during the period November-February. It seems likely that the majority of sperm whales enter the North Sea during southward migration. If the animals do not find their way out in time, they become weakened and many will die at sea or become...

The early specimens of the potto Perodicticus potto (Statius Müller, 1776) in the National Museum of Natural History, Leiden, with the selection of a neotype Naturalis
Smeenk, C.; Godfrey, L.R.; Williams, F.L..
The potto was first recorded and figured by Willem Bosman in 1704. The name Lemur potto Statius Müller, 1776 is exclusively based upon Bosman’s account and figure, which are reproduced in full. The type locality is Elmina on the Gold Coast, the present Ghana. No type specimen was collected. The early pottos in the Leiden Museum are listed and their history is given, with special reference to the animals obtained by H.S. Pel. The publications on this material are reviewed. An adult female, RMNH 39375: mounted skin and skeleton acquired by Pel in 1849 at Dabocrom (Dabo Krom) near Sekondi, coastal Ghana, is designated the neotype of Lemur potto Statius Müller, 1776. The neotype is extensively described and figured. Taxonomic notes on the putative (sub)species...

The find of a whale barnacle, Cetopirus complanatus (Mörch, 1853), in 10th century deposits in the Netherlands Naturalis
Holthuis, L.B.; Smeenk, C.; Laarman, F.J..
A specimen of Cetopirus complanatus dating from the 10th century A.D. is described from archaeological excavations at Tiel, the Netherlands. Two vertebral parts of northern right whales Eubalaena glacialis: a vertebral arch and an epiphysis, were also found, possibly dating from the same period. The disc-like epiphysis had been used as a cutting board. The specimens probably had reached Tiel through early trade in whale products. Cetopirus complanatus is only known from right whales of the genus Eubalaena. It has not been found in the Northern Hemisphere since the late 19th century. Its host species in the North Atlantic and North Pacific, E. glacialis, is now very rare as a result of whaling.

The nomenclature of the African wild ass Naturalis
Groves, C.P.; Smeenk, C..
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...
