tures, principally the fact that the valleys of the crowns of the upper molars as well as the central fields of the lower ones are delicately rugose. The structure of the teeth crowns resemble in the chief features those described and illustrated by KRETZOI (1902) und SULIMSKI (1964), but they seem to be slightly smaller than in PHopetes hungaricus (KRETZOI gave no measurements, only SULIMSKI). The length and width of some teeth of Osztramos 1. are as follows : M, 1.05 X 1.18 1.26 X 1.46 1.34 X 1.62 1.50x1 36 WEZE/SULIMSKI: 1.4x1.8 2.3 X 1.7 Muscardinidae Grlis minor KOWALSKI, 1956 From both localities (1/b and 1/c) there are about 500 teeth, mandible fragments, and extremity bones of the ,,large" dormouse present, forming the dominant element of the small mammal fauna. The remains of this dromouse are, except for the relatively small dimensions and the lesser reduction of the anterior and posterior teeth, very near the only recent species Glis glis, as well as Glis sackdillingensis. It was therefore described originally as a subspecies of the latter species by KOWALSKI (1956) and was raised only later to specific rank (KRETZOI 1959; KOWALSKI. 1963). Fig. 1.
