tip has a lateral widening, rather flat dorsoventrally. It is acutely pointed in most cases, when viewed laterally. The morphology of the penis bone in this species can be regarded as more primordial than that of Rh. affinis. The two species stand close to each other in this respect. Rhinolophus sinicus ANDERSEN, 1905 I have studied two specimens from Ta phinh (extreme North of Vietnam), and another one from Cue phuong, south of Hanoi. All' specimens were collected by me. There is a certain degree of similarity in the morphology of the baculum to that of Rh. rouxi (Plate I., figs. 9-14, Plate n., figs. 1-15). but with well established differences. Measurements: total length 2. 31-2,45. width of basal cone 0,59-0,72, dorsoventral height of basal cone 0,55-0,59 mm. The bone is a rather lightly built structure with a double curvature, and is slightly shorter than in Rh. rovxi . The dorsoventrally flattened basal cone is evidently smaller than in the former species, still, the emargination s on the proximal edge are the same, nor are the outer surfaces with a dorsal knob and a ventral depression different. The shaft is laterally compressed. Its proximal ventral constriction is immediately at the basal cone. In the distal portion of the bone, there is another bend, at two-thirds length, and thus the bone shows an elongated S shape (more pronounced in the Cue phuong specimen) from right lateral view. The ventrally bent tip is with a dorsal sagittal widening and with a double ventral point in the Ta phinh specimens, while it is without such in the Cue phuong animal. In the dorsal view, the tip is narrowly rounded. All these differences, along with those in the cranial and dental characters, pernr.t a differentiation from Rh. rouxi at the species level, while there is no full explanation for the differences between the animals of the two populations studied. Rhinolophus midas ANDERSEN, 1905 I have studied a single specimen collected in the Bumzov Cave, Kashmir. India. Total length of the bone 3,52, width of base 0,50, height of base 0,63 mm. The morphology of the baculum shows a certain similarity to that of Rh. hipposideros , however, the differences suggest a distinctness at species level (Plate HI., figs. 1-3). The baculum is somewhat longer than the maximum size in Rh. h ipposideros studied previously (TOPÁL, 1958). The basal cone is much smaller, higher than wide, with slight and narrow incision on its ventral margin, and a longitudinal median concavity on the ventral surface, with two slight ridges. The proximal margins of the basal cone are thickened. The distal portion of the base is shorter than the ventral one and bulging into a ridge on the dorsal surface. This continues on the dorsal surface of the shaft up to its half length. The distal half of the shaft shows a flat ventral surface. The whole shaft has a lateral compression and a much stronger ventral curvature than in Rh. hipposideros. The tip is with a longish, laterally flattened knob and a slight terminal up-turn at the very end of the bone.
