Choctaw Tribe: Meaning unknown, though Halbert (1901) has suggested that they received their name from Pearl River, “Hachha”. Also called: Ani’-Tsa’ta, Cherokee name. Flat Heads, from their custom of flattening the heads of infants. Henne’sb, Arapaho name. Nabuggindebaig, probably the Chippewa name for this tribe, signifying “flat heads.” Pans falaya, “Long Hairs,” given by Adair.
