New bats (Mammalia: Chiroptera) and new records of bats from Borneo and Malaya J. E. Hill Department of Zoology, British Museum (Natural History), Cromwell Road, London SW7 5BD, United Kingdom C. M. Francis Wildlife Branch, Forest Department, P.O. Box 311, Sandakan, Sabah, East Malaysia Introduction Although numerous bat species are known from Sabah, many records (Medway, 1977) origi-nate in collections made from Mount Kinabalu or from the montane region of which it forms a part. Bats from the lowland areas of Sabah have received less attention and moreover many records are of cavernicolous species. One of us (CMF) has since 1981 been working as a Canadian volunteer (CUSO) for the Wildlife Branch of the Sabah Forest Department. While the principal activity in Sabah has been the management of edible-nest swiftlets (Collocallid) and the study of the rain forest avifauna, it has also been possible to capture and study bats, of which a proportion has been retained as museum specimens for taxonomic and record purposes. Some 65 species have been obtained, including three hitherto undescribed, some, including a new subspecies, representing new distributional records for Borneo, and others of taxonomic or more local distributional interest. This account is limited to the novelties that have been obtained, to those specimens that constitute new records for Borneo, and those that represent taxa so far poorly known. A single new record for Malaya has also been included. The majority of the bats were caught using harp-style traps (Tuttle, 1974; Tidemann & Woodside, 1978). Usually these were placed across narrow trails or streams in the rain forest, or near cave openings. Some bats were also caught in standing mist nets, others by hand or with a butterfly net at their roosts in caves. All trapping has been done at or near ground level, with no work being attempted in the canopy. Most of the collecting has been carried out either at Gomantong or Sepilok. The first of these, several miles north of the Kinabatangan River, about 20 miles south of Sandakan, has a network of limestone caves surrounded by both primary and secondary forest. Large colonies of several species of bats roost in the caves, while many other species are found in the vicinity. Bats from the Gomantong Caves were collected in 1929 by F. N. Chasen, and in 1930 by Senior Forest Ranger P. Orolfo (Chasen, 1931). More recently, Gomantong has been visited by the members of a Japanese group, in 1976 and 1979, the bats collected being reported by Kobayashi et al (1980). These workers also obtained bats at the Madai Caves, whence some of those reported here originate. Sepilok is a virgin jungle reserve located near Sandakan and maintained by the Sabah Forest Department as a research area and wildlife sanctuary. Limited collecting has also been carried out at other sites which are summarized in Table 1 . Many of the more interesting specimens have been donated to the British Museum (Natural History), as have the holotypes of the new taxa described in this paper. All are denoted by their accession numbers, prefixed BM(NH). The final disposition of the remain-der of the specimens examined in London has yet to be decided: all are indicated in this account by their original collector's numbers, prefixed CMF.
