VERTEBRATA HUNGARICA TOM. XXIII. 1989 p. 33.55 Tertiary and Early Quaternary remains of Corynorhinus and Plecotus from Hungary (Mammalia, Chiroptera) By Gy. TOPÁL (Received 23 February, 1987) "Tertiary and Early Quaternary remains of Corynorhinus and Plecotus from Hungary (Mammalia, Chiroptera)" - Topái, Gy. - Vertebr. hung., 2jS: 33-55. 1989. Abstract: Plecotus (Corynorhinus) atavus from the Upper Miocene (MN 13) of Polgárdi Loc. 4, Hungary and Plecotus (Plecotus) pliocaenicus, from the Lower Pliocene of Osztramos Loc. 9, Hungary are reviewed. These species are compared with recent Plecotus (Corynorhinus) townsen- dii, Plecotus (C. ) sp. from Osztramos Loc. 9 and with the holotype (Betfia) and the recently found specimens of Plecotus (C. ) crassidens from the Lower Pleistocene of Beremend Loc. 17 on the one hand, and with Plecotus (P. ) cf. abeli from Osztramos Loc. 9, Plecotus (P. ) abeli from Beremend Locs 1617 and recent Plecotus (P. ) auritus from Europe, Korea, Mongolia and recent Plecotus (P.) austriacus from Europe on the other hand. HANDLEY (1959) discussed the evolution and faunal history of plecotine bats in his comprehensive work. The evolution of these bats has also been studied by WILLIAMS et al. (1970) and FEDYK and FEDYK (1971). Since the publication of HANDLEY's work the existence of two Plecotus (Plecotus) species in Eurasia has been proved and later generally accepted by BAUER (1957), TOPÁL (1958), HANÁK (1966), STEBBINGS (1967) and others. Regarding the European fossil big-eared bats KORMOS (1930), KOWALSKI (1956, 1962) and RABEDER (1974) published important data. While HANDLEY (op. cit. ) ranked the American genus Corynorhinus as a subgenus of Plecotus, RABEDER (op. cit. ) erected the new subgenus Pa- raplecotus to include Plecotus crassidens Kormos. Amongst the numerous fossil bat remains found during the recent decades in Hungary, plecotines have always been relatively rare. Still, these furnished important data on the Miocene, Pliocene and Pleistocene history of the Corynorhinus-Iike (

Paraplecotus) bats and that of Plecotus (Plecotus) in the Pliocene and Lower Pleistocene of Hungary. Two new species were described by TOPÁL (1988). LOCALITIES, MATERIAL AND METHOD Polgárdi Locality 4 (both lower and upper localities). - A very rich and in many respects relatively intact vertebrate material aged Upper Miocene (MN 13) (about six million years old) was collected here in 1984-1985 for the Hungarian Geological Institute by Dr. L. KORDOS. There are some publications on the mammalian remains by KORDOS (1985, 1987, FREUDENTHAL and KORDOS (1987). Amongst the numerous - unpublished yet - insectivores, rodents, etc., the bats seemed but additional elements. Still, a good number of Rhinolophus
