Vertebr. Hung. XVI. 1975. Baeula of Some Old World Leaf-nosed Bats (Rhinolophidae and Hipposideridae, Chiroptera: Mammalia)' TOPÁL, György Hungarian Natural History Museum, Budapest ABSTRACT: Descriptions and figures of bacula of 26 bat species and subspecies of Rhinolophidae and Hipposideridae in the collections of the Hungarian Natural History Museum from the Old World (except Africa and Europe) with taxonomic notes and considerations. INTRODUCTION The importance of the morphology of bacula in the taxonomy of Chiroptera is well known, and already discussed in works deeling with bacula of European (MATTHEWS, 1937; LANZA, 1959, 1960) and North American (HAMILTON, 1950; KRUTZSCH and VAUGHAN, 1955) bats. Our knowledge is, however, very limited about the bacula of bats in the greater part of the Old World. This holds especially for microhiropteran species (TOPÁL, 1970). In this paper, I propose to submit the results on the species of the most difficult families (or "genera") of the Hipposideridae and Rhinolo phidae. I used the collections of the Hungarian Natural History Museum and the material I collected in Vietnam and India. The study covers mostly Asiatic species, and for comparisons I included a few other bats from New Guinea and Australia available in the Budapest collection. At present, the African species are fully ommitted. I used the alizarin-red staining method (TOPÁL, 1958). Due to the state of preservation, a proper study of the soft parts could not be carried out. This would need a more adequate, fresh material. DESCRIPTIONS AND RESULTS Rhinolophidae Rhinolophus ferrumequinum proximus ANDERSEN, 1905 I have studied one specimen collected in the Bumzov Cave, Kashmir, India. Total length of baculum 4,94, width of basal cone 1,72, height of basal cone 1,27, width of lancet 1,00 mm. The bone is very similar to that of the nominate subspecies, however, considerably bigger, with a less bent shaft, with a longer and dorsoventrally more flattened basal cone and with a longer lancet when viewed from above. There is a longitudinal ridge on the dorsal surface of the basal cone. The dorsal side of the lancet is flat, and a main median ridge runs on its ventral surf; e. The
