As to the occurrence of accessory triradii in interdigitum 3 of the human palm.
Analysis of extensive dermatoglyphic data, collected from West Kenya by Doz. E.M. Winkler, showed considerable intergroup variability in the frequencies of accessory triradii in the third interdigital area (interdigitum 3) of the palm. A review of the literature confirmed the universally low frequency of this trait, as well as its racial variability, with the Negroes having the highest frequency.
