Fragm. Min. et Pal. 9. 1979. Fossil Bats of the Rhinolophus ferrumequinum Group in Hungary (Mammalia: Chiroptera) György TOPÁL Hungarian Natural History Museum. Zoological Department. Budapest ABSTRACT. A detailed comparison of fossil bats of the Rhinolophus ferrumequinum group from Hungarian localities, some from Poland and France, as well as recent specimens in the collection of the Hungarian Natural History Museum is given. Five new fossil taxa: Rhinolophus kowalskii n. sp., Rhinolophus estramontis n. sp. , Rhi nolophus postdelphinensis n. sp. , R

hinolophus macrorhinus anomalidens n. ssp. and Rhinolophus ferrumequinum tarkoensis n. ssp. are described. K. ANDERSEN (190 5) revised the family Rhinolophidae and also the recent forms of Rhinolophus ferrumequinum of his time. He described Rh. f. regulus and Rh. f. proximus as new subspecies of the Great Horseshoe Bat. From then a series of new forms were described as: Rh. f. insulanus BARRETT-HAMILTON 1910 from England, Rh. f. iráni CHEESEMAN 1921 from Iran, Rh. f. mikadoi OGNEV 1927 from Japan, Rh. f. quelpartis MORI 1933 from Quelpart Island off shore of Korea, Rh. f. korai KURODA from South Korea. Recently, FELTÉN et Al. (1977) summarized the taxonomy of the western forms of Rh. ferrumequinum. The fossil species and forms belonging to the ferrumequinum group were rather neglected as only Rhinolophus delphinensis GAILLARD 1899, Rhinolophus lemanensis REVILLOD 1919, Rhinolophus pleistocaenicus YOUNG 1934, Rhinolophus csakvarensis KRETZOI 1951, Rhinolophus ferrumequinum mellali LAVOCAT 1961, Rhinolophus macrorhinus TOPÁL 1963 and Rhinolophus ferrumequinum topali KRETZOI 1977 were described. Practically all the other palaeontological works dealt with Rhinolophus delphinensis"

and could not recognize sufficient or had not enough material to classify the position of the different fossil populations. During the recent years a good number of new fossil localities also with more or less remains of some Great Horseshoe Bats become known from Hungary. The necessity of identification and later that of revision of them, become a more and more important task. Therefore I took the opportunity to study these along with the material of some foreign localities and a few recent populations too. MATERIAL AND METHODS Localities La Grive.

. The fauna was recently studied by VIRET (1951). Some cranial and other fragments of Rh. delphinensis have been received by the courtesy of Dr. P. MEIN, Csákvár. KRETZOI (1951) had studied the fauna of this Mio-Pliocene site. The same author described Rh. csakvarensis of which the type material was used in this work. Podlesice. KOWALSKI (1956) has studied the fauna of this Pliocene locality in Poland and described it in details. He identified Rh. cf. ferrumequinum there. Later (KO-
