In this investigation were studied 200 men and 200 women commonly 400 individual of both sexes, according to 16 dermatoglyphic traits, from the regions of Melnik and Petritch. The processing and the analysis of the dermatoglyphic material was done according to the method of Cummins and Midlo (1961). In order to be established significant differences among the studied groups, according to the dermatoglyphic traits, was used the method of t-criterium. It was done race-diagnostic analysis according to the percentage frequency of the studied dermatoglyphic traits and was established that the explored Bulgari an population from these regions belongs as a whole to the europeoid race. Besides, it was established a bimanual with respect to the dermatoglyphic paterns on III interdigital pad, which are more frequently on the right hand, than on the left hand. It was not established a sexual dimorphism (statistically significant) in the studied population from Melnik and Petritch by the dermatoglyphic traits. On the basis of the mathematic-statistical processing, by means of t-criterium, it was established, that by the majority of the dermatoglyphic traits, the differences between the studied population from the regions of Melnik and Petritch are statistically insignificant, witch is an indication for their closenes by this traits. .
