PULACUAM INDIANS. In 1690 the Pulacuam (Pulacmam, Pulacman) Indians were encountered by Spaniards on the headwaters of the "Río Medina," which could be either the present Medina River or the San Antonio River. This suggests that their range was along the southern margin of the Edwards Plateau west of the site of present San Antonio. On the Río Medina they were encamped with five other bands, all apparently of Coahuiltecan affiliation. Swanton stated that the Pulacuam Indians may have been Coahuiltecan or Tonkawan in speech, but none of the evidence now available supports a Tonkawan affiliation. Herbert E. Bolton suggested that the Pulacuam Indians may have been the same people as the Sulujam Indians. This is a guess based on presumed phonetic resemblances in the names and is not acceptable.
