. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. c Fig. 6: Bacula of three species of fruit bat; dorsal (above) and lateral (below) views, a: Latidens salimalii (MM225). b: Penthetor lucasi (), Telok Asam, Sarawak, c: Cynopterus sphinx (), Haldwani, UP, India. Scale = 1 mm. Stereomicroscope drawings by N. M. Thomas. (PM4) and in Ml which does not taper posteriorly. Lower incisor simple and peg- like. Lower canines situated close together, in marked contrast to Cynopterus. Small anterior premolar (pml) smaller in crown area that that of C. sphinx, consequently larger gap between it and second lower premolar (pm3). Posterior cheekteeth all massive, with second lower premolar (pm3) very heavy and with large anterior cusp; third premolar (pm4) is molariform in structure, almost square in outline and with a low elevation in the central valley which fissures with wear (Fig. 5). ml is smaller but otherwise similar in structure to pm4. m2 less reduced than in C. sphinx and with a more squarish outline; exceeds first premolar (pml) in crown area. The dental for- mula used above follows the interpretation of Andersen (1912, page xxvii) for the Cynopterine section. Baculum relatively massive; shaft ovoid and dome-shaped with a hollowed out ventral surface; tip small with a ventrally hooked projection. In Fig. 6, it is compared with Cynopterus sphinx and Penthetor lucasi (Dobson, 1880), a Cynopterine species which L E. Hill (in Thonglongya 1972) considered closely related to Latidens. In both cases, differentiated not only by its much larger size but also morphology. Baculum of C. sphinx has characteristically well developed shoulders and simple unexpanded tip. In P. lucasi, general morphology of shaft is comparable to that of Latidens but tip is simple, essentially similar to that of Please note that these images are extracted from scanned page images that may have bee
