Hipposideros durgadasi KHAJURIA, 1970 This recently described form has a very characteristic, strongly bant bone, which is quite different from that of H. cineraceus (Plate VÏÏ., figs. 18-20). So we have to treat H . durgadasi not as a subspecies of H. cineraceus but a distinct and good species. I have studied one specimen from near the type-locality, Gwarighat, Jabalpur, Central India. Measurements: distance between tip and basal end 1,27, width of base 0,18, width of shaft 0,09 mm. The bone can be regarded as a very much specialized derivate of the cineraceus type. The basal portion is a simple, ventrally carved widening, instead of a double basal cone with emarginations. The bending of the shaft is towards the ventral side, and reaches an extreme degree: it describes a semicircle. The shaft itselt is a dorsoventrally flattened, rather ribbon-like structure with a pointed tip and a ventral longitudinal depression. Hipposideros calcaratus POBSQN, 1877) A single New Guineán specimen was studied. Measurements: total length 1,86, width of base 0,45, spread of the terminal fork 0,95 mm. On the basis of the morphology of the baculum, this species is related to the Asiatic species of the speoris and armiger groups with an enlarged terminal fork (Plate VIII., figs. 8-10). It seems as if it were a transitional form between a basic type (cine raceu s like ) and the la rvatus stage. The bone has a bulky, shovel-shaped basal portion with no trace of a basal cone. The thickest and narrowest part of it is proximally situated and dorsally bulges out. The shaft is distally diverging to the terminal fork. It is dorsoventrally flattened and dorsally bent to the basal portion. At the transitional point it has a constriction and a ventral depression. The terminal fork expands with widely roundtipped branches which are pointing dorsally. Hipposideros armiger armi ger HODGSON, 1835 There have been studied three specimens of a small series collected at Lopchu near Darjeeling, India. Measurements: total length 1,86-2,08, width of base 0,55-0,63, height of base 0,41-0,50, span of tip 0,72-0,83 mm. The relatively small, short and stout baculum has a terminal fork. (Plate VTO.'", figs. 11-16). However it is straight with a strong ventral bent at the terminal bifurcation. The basal portion is a moderately wide, thick, dorsoventrally flattened structure with a proximally directed strong ventral lobe. A faint emargination is on the proximo-ventral margin of the bone. The dorsal surface of the base is definitely convex, while there is a concavity on the ventral one. The shaft is extremely short. Its narrowest protion, both from the dorsal and lateral views, is at the middle length of the bone. It is dorsoventrally flattened with a convex dorsal surface and a definite longitudinal depression on the ventral side. The terminal fork shows a wide, ventrally carved-out base; the ventrally directed as well as laterally flattened tapering branches enfold the urethra from above.
