This ridge or bar is hardly discernible from occlusal view, although in many others it is well seen as emerging from the flat lingual surface of the crown, or even united with the convex anterior surface of the shaft. This case is seen mostly in those teeth where the basal cross-sectional width is great. In the Beremend specimen the anterior surface is rather narrow. It is continued on buccal side with an obliquely convex surface anteriorly. Further, there is a sharp ridge medially, and a concavely flattening surface posteriorly. A sharp cutting edge is present and there is a small cin­gulum cusp on the posterior end of the crov/n. The basal cross-sectional length/width index of the Beremend specimen is 0.79, which expresses the flatness of the shaft. Besides, the basal cross­sectional outline is obliquely cut on the lingual side posteriorly. This is not so in most of the spe­cimens used for comparison, where it is rounded off, even in those teeth which have more or less lateral flatness. One specimen with 1.22 mm length and 0.97 mm width from Gundersheim also has an index of 0.79, while the others measured are 1.13-1.27 mm in length and 1.02-1.06 mm in width with indices 0.85-0.90. All these have more or less rounded-off posterior portion of cross­sectional outline in occlusal view. In the Osztramos 9 locality, there were also a few similar spe­cimens. One with an index of 0.80 measured 1.18 mm in length and 0.95 mm in width. Some are with 0.71-0.73 indices and with lengths of 1.20-1.36 mm and widths of 0.86-1.00 mm on the one hand, and with indices of 0.86-1.00 and lengths of 1.13-1.31 mm and widths of 1.09-1.18 mm on the other hand. Further specimens of Myotis cf. kormosi from Csarnóta 2 locality have indices of 0.78-0.81, however these are slightly greater (basal cross-sectional length 1.27-1.31 mm, width 1.00-1.09 mm) than the Beremend specimen, and those with lower indices (0.70-0.72) have lengths of 1.18-1,31 mm and widths of 0.86-0.95 mm. One with an index of 0.85 is 1.18 mm long and 1.00 mm wide in cross-section. Myotis blythi (Tomes, 1857) ssp. One left upper M 3, one right lower C collected by D. JÁNOSSY and the author in November, 1981. One injured proximal portion of a right radius obtained by L. KORDOS in 1982. Measurements: Antero-posterior length of upper M 3 1.04 mm, width of M 3 between lingual and parastylar margins 2.50 mm. Length/width index 0.42. Lower C basal cross-sectional length 1.18 mm, width 1.22 mm. Remarks . Comparisons were made with 32 recent specimens from the Carpathian Basin and a series of 53 fossils from the Middle Pleistocene of the Tarkő Rock-shelter. Unfortunately, the earliest known Hungarian pieces of the species from the Pliocene of Osztramos 9 locality lack upper M 3. The Beremend 15 upper M 3 fits between the higher values of the length of 32 recent teeth, being, however, somewhat longer than the mean (0.9771) of these (see: Fig. 1), The measurements and values of 53 fossils from Tarkő are slightly higher with 1.0115 mean of length measurements. As regards M 3 width, the mean of the recent values is the highest with 2.5296 mm, medium is that of the Tarkő fossils with 2.5237 mm, and the width of upper M 3 from Beremend is the smal­lest. A most interesting tendency is seen, however, in the changes of width/length ratio. This is over 0.42 in the Beremend Loc. 15 tooth, between 0.37-0.42 in the Tarkő fossil3 and 0.35-0.41 in the recent animals studied. As it is evident from Fig. 1, the specimen from Beremend 15 locality is difficult to allocate, and in order to see whether it falls into the range of variation of the Tarkő fossils further statistical tests were carried out. Normal probability plots were computed to detect any outlyers. Fig. 2 depicts plots for both the fossil and the recent groups. It can be seen from Fig. 2A that the recent specimens fairly well fit to a straight line, indicating a normal distribution Fig. 3. Variation of dental characters in fossil and recent Eptesicus praeglacialis and E.serotinus. A= lower Ml length, B= lower Ml talonid width, C= lower P4 length, D= lower P4 width, E= upper C cross-section length, F= upper C cross-section width, G= upper Ml length. Measurements in millimeters are given on the vertical axes. For each locality (1= Csarnóta Loc. 2, 2= Beremend Loc. 15, 3= Püspökfürdő, 4= Nagyharsányhegy, 5= Tarkő, 6= Recent), the vertical line represents the observed range; the horizontal line indicates the mean (or single value); the black bar marks one standard deviation on either side of the mean and the rectangle indicates two standard errors above and below the mean. In cases of standard deviation exceeding the range, this is omitted and ranges and means are shown. The sample size for each locality or population is given below the vertical line
