Description see below. Chiroptera indet. According to oral communication by GY. TOPÁL, there are at least two Rhinolophus and more Vespertilinionid species present.

Otherwise the shape of the molars is very near the recent Sciurus, but the mesostylid and the mesoconid are more strongly marked at lower molars and the same teeth have four roots. The central fields of the crowns are smooth. Sciurus aff

3 without roots, originating from locality 1/c, shows clearly Sciurus features, but it is slightly larger and broader than that of the recent squirrel (anterior width: 2.65; lingual length: 2.82). The protoconid is not separated from the anterolophid, as in Spermophilinus turolensis, but decurrent lingually in a well-marked crest. The mesolophid and the mesostylid are just discernible. The labial side of the posterior cingulum (i. e. the posterior margin of the talonid) is well developed, more so than in Spermophilinus. On the basis of the size as well as the morphological features, the remain stands nearest Sc. wartime SULIMSKI, without speaking of identity. Pliopetes sp. An M
