In a recent note Baerreis (1950) has given critical amplification to the question of possible cultural relations between the southeastern United States Archaic and the archaeologically known culture, or cultures, of the lower Parana River, Argentina. A paper of my own (Willey, 1949), on which Baerreis centers his discussion, focused attention on the Caribbean area and the north of the South American continent, giving only brief mention to interesting southeastern resemblances which may be found along the Parana and in the Sambaquis of southern Brazil. I agree that Baerreis has strengthened the case for cultural connections over and beyond the casual comments which I or others have offered.
