Lower Pannonian (Pannonian s. s. ) medium-sized cricetid that are characterized by Neocricetodon schaubi and by the genus classified formerly as Kowalskia. Now it is considered as Neocricetodon fahlbuschi. Neocricetodon schaubi from Csákvár was a nomen nudum in 1930 (KRETZOI, in KADIC and KRETZOI 1930). Later, however, KRETZOI (1954) published the description, denoted its holotype, but gave no figures. From all this we can conclude that the genus and species is valid. On the basis of Neocricetodon schaubi of Csákvár, a continuous evolution in morphology and size can be proved that started at Csákvár and went on through the Sümeg and Kohfidisch finds (Fig. 11). This tendency is interrupted and becomes controversial during the Fig. 11 Evolution of the MN 10-13 ages Neocricetodon and Karstocricetus genera in the Carpathian Basin. The horizontal line is the area of the tooth crowns in mm; the vertical line is time. See the text for explanation process. New variations in size and more intricate tooth morphology containing also ectomesolophid appear. This new trend of evolution is documented and characterized by the genus Karstocricetus found at Eichkogel (formerly Kowalskia cf. fahlbuschi , now Karsto- cricetus skofleki ), Széchenyi Hill in Budapest, and Tardosbánya in the MN 12 zone. All these trends of evolution are well distinguishable even if the chronology of the Csákvár, Sümeg and Kohfidisch sequence would be changed in the future. Such a revision, however, is unlikely and it would contradict the so far generally accepted ideas (KRETZOI 1969, 1983, MEIN 1971). Beside Neocricetodon fahlbuschi the Cricetulus sp. I. also appears at Sümeg. 3. According to the present concept Cricetus kormosi SCHAUB from Polgárdi cannot be considered to have evolved from the Cricetidae living earlier in the Carpathian Basin. Cricetus kormosi differs both from the earlier and later genera (Neocricetodon-Karstocricetus and Kowalskia, respectively). It is of different size, has a high tooth crown, and a characteristic occlusal tooth crown surface. The determination of the place of the Cricetus kormosi no other Cricetidae were found in the Carpathian Basin. Therefore one may suppose that there is no direct phylogenetic relation between the Late Mioecene and the Pliocene taxa. 4. At present no data are available concerning the cricetids living in the earliest MN 14 in the given region. 5. In the zones MN 14 and 15 Cricetus kormosi is already absent. Kowalskia polonica FAHLBUSCH, K. magna FAHLBUSCH and Cricetulus sp. II. appeared in the Osztramos 1 locality (MN 14). In the MN 15 zone at Ivanovce the following taxa could be found together: Kowalskia intermed ia FEJFAR, Cricetus sp., Allocricetus cf. bursae SCHAUB and the
