upper part of the Middle Pleistocene. It has to be mentioned, however, that this feature is not very useful, because - measuring the Sorex mandibles from the Late Pleistocene Istállóskő Cave -1 found same large specimens within that material, too (Table 4). Chiroptera For the determination of the bat remains thanks are due to György TOPÁL (Hungarian Natural History Museum, Department of Zoology, Collection of Mammals). The material shows neither the mild climate nor the older age. A very worn molar was found in layer 6, and was determined as Myotis schaubi. In accordance with the present data this species became extinct in the Early Pleistocene. Both this fact and the strongly worn condition suggest, that the tooth was redeposited from older beds. Rodentia I classified the ground squirrel remains into the Citellus citelloides Kormos species. Many teeth and bones were found in each layer. Measuring the length/width data of the third lower molars (M

), those were smaller without exception than at the recent Citellus citellus L. (Fig. 6).
