Dermatoglyphics from two southern Peruvian Indian groups, Nunoa Quechua and Quechua ‘Pooled’, and a North-Central Peruvian group, Vicos Quechua, were evaluated for' digital and a-b palmar interdigital ridge counts. In addition to total ridge counts, the results are presented in terms of ulnar and radial counts and by digital pattern. Ridge counts of the southern Peruvian Quechua groups are similar to each other, but are significantly different from the northern Vicos Quechua; all three Peruvian groups have lower ridge counts than the Chipaya Quechua of Bolivia. Differences between ulnar and radial counts of loops and whorls suggest that lateral evaluation of ridge counts may provide additional polymorphic dermatoglyphic markers which could be utilized in anthropological and genetic studies.
