In the second half of the 19th century, the rhinoceros occurred throughout Borneo except southern Sarawak, northwestern Kalimantan and some parts of southern Kalimantan. The animal was extinct in the coastal and other populated areas in about 1930, especially in the southern part of Kalimantan. Presently some small populations remain, scattered over the Sarawak interior (if the rhinoceros survives at all there), northeastern Sabah, possibly also southern Sabah and around Mt. Kinabalu, and the interior of Central and East Kalimantan. It is estimated that some 15 to 25 rhinos are still alive in Borneo. |

The historical background of sixteen taxa in the family Rhinocerotidae is examined in order to assess their types and present status unequivocally. Various taxonomic or nomenclatorial aspects are treated of the following specific names: africanus, annamiticus, asiaticus, brucii, camperi, camperii, camperis, capensis, cucullatus, gordoni, inermis, jamrachi, javanicus, javanus, sondaicus and sumatrensis. A short discussion on the definition of “iconotype” is added. |

INTRODUCTION The first scientific description of the Komodo Dragon (Varanus komodoensis), given by P. A. Ouwens, appeared only as late as 1912. During some time following this event, but little information on the species became available and no specimens were captured. Only in 1926, an American expedition to the island of Komodo, led by W. D. Burden, for the first time succeeded in capturing alive two Komodo Dragons and in transporting these to the U.S.A. Both animals were received at the New York zoological garden on 11 September 1926. One of the specimens, a male, died on 24 November 1926; the other, of unknown sex, died on 19 October 1926 (Jones, 1965: 92). On 14 October 1926, a male Komodo Dragon was received at the Amsterdam zoological garden. It was... |

It has been asserted that Petrus Camper (1722-1789) was the first to distinguish the Javan Rhinoceros as a separate species. This opinion is based on a cursory remark in a posthumously published letter to the Russian scientist Peter Simon Pallas. A careful analysis of Camper’s numerous writings on the rhinoceros, both published and unpublished, has produced not the slightest confirmation of this taxonomic achievement. Therefore, it seems premature to label Camper as the discoverer of the Javan Rhinoceros. As Georges Cuvier made ample use of the material collected by Camper, we have also discussed its influence on Cuvier’s ideas with respect to rhinoceros classification. |

On 6 October 1764, Adriaan Vroeg sold his collection of birds, insects and a few other animals by auction. The sales catalogue was published anonymously, but contained several scientific names of birds, which have nomenclatorial standing. Only three copies of this catalogue are known. The appendix entitled “Adumbratiunculae” has previously been attributed to Peter Simon Pallas, who is quoted as author of the new names of birds. In the present note, the main text is credited to Arnout Vosmaer, on the basis of contemporary references. Where the species names proposed by Vosmaer are synonyms of those published by Pallas in the same volume, the latter are selected, because some names have been validly used before with Pallas as the author. |

Rousettus amplexicaudatus (Geoffroy, 1810) is divided into three subspecies according to size: R. a. amplexicaudatus, R. a. infumatus (Gray, 1870), and R. a. brachyotis (Dobson, 1877). Cynonycteris minor Dobsou, 1873 is synonymized with R. a. infumatus; Rousettus stresemanni Stein, 1933 with R. a. amplexicaudatus; and Rousettus amplexicaudatus hedigeri Pohle, 1952 with R. a. brachyotis. Geography and dimensional variations of the recognized subspecies are discussed. R. amplexicaudatus is recorded for the first time from Celebes, Kisar, Mentawai, Muna and Ndao. The subspecific status of specimens from Celebes, Muna, Peleng and Talisai is left undecided. Other Rousettus species are discussed in so far as they are known to be sympatric with certain R.... |
