ATANAGUAYPACAM INDIANS. The Atanaguaypacam Indians (Atanaguipacane), who were apparently Coahuiltecan in speech, lived on the Gulf Coast near the mouth of the Rio Grande. In the middle eighteenth century their settlements were reported to be along the shores of the numerous small bays and islands near the mouth of the Rio Grande.
