A method for subtyping the interdigital patterns is introduced, which is based upon the direction of the main line terminations as well as the presence of accessory triradii. The palmar patterns of several population samples from our files representing the Caucasians, Negroes, Miconesians and New Guinean groups are evaluted in terms of the introduced calssification and the results demonstrate a number of differences between the major racial groups. In additin, the thenar/I and hypothenar patterns are subtyped according to the classifications of Cummins and Midlo. These data also indicate the inadequacy of the general open/arch, vestige, loop, whorl identification of the plamar patterns. It is hoped that more data will be studied along these lines for establishment of more accurate frequencies among the various racial groups.
