Hipposideros bicolor sinensis ANDERSEN, 1918 There have been studied 3 specimens of this middle-sized Hipposideros collected at Tuong linh, North Vietnam. Its baculum is a very simple, small and most probably rudimentary structure, resembling that of H, galeritus (Plate VI., figs. 14-20). Total length 0,50-0,61, width of base 0,09-0,15. The proximal end is a more or less simplex knob with a slight ventral cavity. The shaft is ventrally bent, paraUel-sided or with convergent margins towards the tip and with a faint flatness or cavity on the ventral surface. The end portion has a rounded tip. The bone is situated in the very tip of the glans penis, thus mostly protruded during preparation and the drying of the skins, and very likely lost in some cases - a probable cause of its absence in a few other specimens studied - despite the use of the alizarin red staining method. Hipposideros ater ater TEMPLETON, 1848 There was collected a small series of this species from Konarak, Orissa, India. Two of them were dissected for this work. Another specimens were studied from Gwarighat, Central India, and Hingolgadh, South India. Measurements: total length for Konarak specimens 1,68-1,72, for the others 1,50-1,54, basal width 0,31 and 0,25-0,27, respectively. Height of basal cone 0,22-0,25 and 0,25-0,27. In general the bone well agrees with that of some other species in the bicolor group (Plate VTI., figs. 1-7). It has a more or less developed basal cone (as usual, it is less developed in younger animals) and a simple, not bifurcating end portion. Among the species studied, the bone is most similar to that of H. fulvus ? still it can easily be distinguished. It has a more developed basal cone, its shaft is dorsoventrally flattened instead of being laterally flat, and its tip is rounded when viewed dorsally instead of being pointed as in H. fulvus. The ventral bend of the bone is less pronounced as in H. fulvus. The dorsal flatness of the tip is well discernible also from the lateral view. The size differences in the bacula from the three localities are not well explained, and a study of a greater series may show them to be individual deviations. Hipposideros gilberti JOHNSON, 1959 One specimen was secured in exchange from Australia, collected in the Cutta Cave, Katherine, N.T. by T.L. MCKEAN 4 W.WALSH, and identified as H. ater . Over the differences in the dental characters as shown by H. ater , the morpholgy of the Daculum certainly indicates a quite different and good species. Pending a thorough study of its taxonomic position, I apply JOHNSON* s denomination as geographically the nearest one. Measurements: total length 0,86, basal width 0,37 mm. The baculum, disregarding its small size, clearly shows the bifurcating type of the Asiatic species of great body-size, with no relation to the true H . ater , or to any other species of the bicolor group (Plate Vn., figs. 8-10). The basal portion of the bone is relatively small and narrow, but wider than high dorsoventrally . Its proximal surface is moderately carved out. It is dorsally flat, or rather, with a slight concavity at the median line. Ventrally, it displays a concave surface in the median line, the concavity extending to the middle portion of the shaft. The latter is extremely short and its length together with that of the basal portion is less than half of the total
