ted along a common line in the diagram. This suggests a strong genetic relation between them, although there is a slight geographic variaiton, as wel. 2.22. The lack of significant (or any) correlation beween the diameter of maxillar M, and body size (CB) is one more reason for regarding the former as distinctive specific characteristic. Body size, wich is dependent on elevation, does not alter the diameter of M.. The correlation coefficient for Talpa romána ehiki and Talpa europaea (Hungary} are г = 0,29 and г = 0,26 (с. f. Tab. 5), whereas in Talpa romána stankovici г = 0,1156, in Talpa romána terra typica г = 0,66 (а slight correlation Р = 1 %). Figure 3. А - Lateral view of the upperset of teeth of Talpa europaea L.

д 2.30. Regression of rostral width on CB 2.31. As the fourth step the rostral width was plotted against CB for the populations mentioned in 2.21. (Figs. 6,7). Linear regression equations were calculated, Concerning rostral width, wich used to be regarded as distinctive specific characteristic the following can be stated: In the case of all the four Talpa romána populations it has much higher correlation with CB, than the diameter of maxillar M, has. In the case of three„of the four populations this relation is significant at a level of 0,1 %, and г vanes between 0,31 and 0,62. This proves indirectly, that habitat factors have strong (30 - 60 %) effect on restral width. 2.32. In the rostral width (CB diagram the isolation of Talpa romána populations can be recognized (c. f. Figs. 6,7). Studying the distance between Talpa romána ehiki and the other three populations it seems to be possible, that Southern French population of Talpa romána could fit into this gap (?). Talpa europaea populations are groupped along a common line. Rostral width of Talpa romána ehiki is somewhat similar to that of S-Italian Talpa europaea population, which can be explained by differences in the habitats, as it was discussed above. 2.40. Regression of the dianreter of maxillar M, rostral width 2.41. As the fifth step ,the diameter of maxillar M, of Talpa romána populations were plotted against rostral width (Fig. 8.). The Same was done for Talpa europaea populations (Fig. 9). The behaviour of these two variables was quite different in the case of the two species. Talpa europaea populations are dist distributed arount a common centre. It is worth mentioning, that the southern the location of the population, the higher the standard deviation around the common centre. 145
