Hipposideros alongensis BOURRET, 1942 There have been studied two specimens from a series, of 21 males collected in Cue phunong, Vietnam. The baculum resembles that of H. armiger and H. gilberti, and shows no close relation to the penis bone of H. larvatus (Plate rx., figs. 1-9). Thus, BOURRET' s original assumption has no ground regarding the taxonomic status of the present animal. Measurements: total length 1, 50-1, 63, basal width 0,45-0,52, height of basal portion 0,36-0,40, greatest span of terminal fork 0,55-0,57 mm. The relatively small bone is situated in the terminal half of the glans penis, with its narrowest portion at the middle length (just as in H. armiger) but with a shorter shaft and a longer terminal fork as well as basal portion. It displays a weaker ventral bent than H. armiger, but at middle length (lateral view). The incision on the proximo-ventral margin is stronger than in the preceding species. The dorsal surface of the basal portion and that of the terminal fork at the bifurcation reveal a definite concavity. The ventral median depression reaches its deepest section on the ventral surface of the base. The branches of the terminal fork are roughly cylindrical and tapering towards the bluntly pointed tip. They are deviating distally, then converging from the minddle length, as in H. gilberti. The main difference between these two species is in the direction of the terminal fork. Hipposidros galeritus brachyotus pOBSON, 1874) I have studied one specimen from Ajanta, India. The baculum of this animal is a trifle bigger than that of H. bicolor sinensis, with a resemblance to the latter (Plate IX., figs. 10-12). Measurements: total length 0,40, width of base 0,13 mm. Its proximal portion is wide but very low. It shows a trace of a basal conical cavity, and it is slightly two-lobed when viewed from above. There is a faint asymmetry in the shaft, having sharp margins both on the upper right side and on the lower left one. A flat surface can be seen from the base up to the middle height of the shaft on ventral side. From the lateral view, the bone is almost quite straight. The end portion exhibits a dorsoventrally flattened, slightly up-turned, knob-like tip. Aselliscus tricuspidatus (TEMMINCK, 1835) One specimen, collected in New Guinea, was used for this study. Measurements: total length 0,95, width of base 0,22, width of tip 0,20 mm. A strong asymmetry appears in the shape of the baculum unique among the Old World Leaf-nosed Bats studied, as the bone is S-shaped in the right lateral view while the ventrally projecting apical lappet turns sharply to the left (Plate IX., figs. 13-14). The basal portion is dorsoventrally flattened and with a dorsal knob. The shaft is distally tapering to the widening base of the strongly flattened, truncate apical lappet. Coelops frithii inflatus MILLER, 1928 A single specimen was studied from a small series collected at Gia phu, North Vietnam. The baculum is similar in some respects to those of H. fulvus and H. ate r (Plate IX., figs. 15-17). Measurements: length 1,95, greatest width 0,13, width of
