The Taxonimic association of mus faberi Jentink with Rattus xanthurus (Gray), a species known only from Celebes (Rodentia: Muridae)

Over 60 named forms of Rattus are recorded from Celebes (Laurie & Hill, 1954). Some of these names were first proposed in the i8oo's. The taxa they represent were sometimes based on only one specimen and were often poorly diagnosed. Consequently, the taxonomie status of the names has been unclear. Such names are stumbling blocks to accurate identification and sound classification of the species of Rattus which occur on Celebes. Mus faberi, named and described by F. A. Jentink in 1883, is a classic example. The name represents a taxon based on a single specimen. The original description of that specimen was short and vague. No other specimens have ever been allocated to M. faberi in the mammalogical literature and the taxonomie status of the name has remained obscure since Jentink proposed it. I had the opportunity of examining the holotype of M. faberi during a recent visit to the Rijksmuseum van Natuurlijke Historie in Leiden. Results of that study are offered in the present paper wherein M. faberi is associated with Rattus xanthurus. ABBREVIATIONS AND METHODS The specimens discussed in this paper are in the collections of the American Museum of Natural History (A.M.N.H.), the British Museum (Natural History) (B.M.), the Rijksmuseum van Natuurlijke Historie (R.M.N.H), the personal collection of H. J. V. Sody (these specimens are housed in the Rijksmuseum van Natuurlijke Historie and will be indicated as "Sody No."), and the United States National Museum of the Smithsonian Institution (U.S.N.M.). Measurements of the length of the head and body and the length of the tail are those of the collectors and were taken from labels attached to study skins. I measured the length of the hind foot of all th

A new genus of arboreal rat from West Java, Indonesia

Kadarsanomys nov. gen. is proposed for Rattus sodyi Bartels, 1937, and contrasted with Rattus and Lenothrix, two genera with which sodyi has been closely connected in the past. Kadarsanomys sodyi is an arboreal rat associated with bamboo on the forested volcanoes of West Java. Kadarsanomys has no close relatives and is the only murid genus endemic to a single island on the Sunda Shelf. Kadarsanomys, Pithecheir and Lenothrix comprise the only endemic genera of Sundaic murids

A new species of Hydromys (Muridae) from Western New Guinea (Irian Jaya)

A new species of the murid Hydromys is named and described, based on skins, skulls and denti tions. The sample comes from the Wissel Lakes region in the Indonesian half of New Guinea (Irian Jaya). In many features, the new species is a miniature version of Hydromys chrysogaster and may be more closely related to that large water rat than to H. habbema. Nothing is known about habits or habitat of the new rat, and it has not yet been collected elsewhere in Irian Jaya or in the eastern half of New Guinea (Papua)
