Acareful review of field notes and collections from Tiahuanaco, Chiripa, and Pariti and comparison with the preliminary reports by Kidder on Pucara and M. Tschopik on the north Titicaca basin suggest a change in the position of Chiripa in the Bolivian sequences previously reported. The evidence for this change is briefly reviewed.

The Chiripa mound has four major levels: (1) top soil, from 0 to .50 meters; (2) post-house level, from .50 to 2.0 meters; (3) house level, from 2.0 to 3.0 meters; (4) pre-house and premound levels, from 3.0 to 5.0 meters. The house and pre-house levels, (3) and (4), contain unmixed Chiripa materials. The post-house levels, (1) and (2), show a continuation of Chiripa materials plus an intrusive Decadent Tiahuanaco, represented by burials, sherds, a semi-subter-ranean temple, and a facing wall.
