An important tribe of Shoshonean stock closely resembling the Pima. Their habitat was Ariwna and Sonora, Mexico. They were sedentary and agricultural and skilled in basketry. At enmity with the Apaches they were friendly to the whites. Father Kino founded the mission of San Xaver del Bac in 1681. They are now Catholics and civilized, numbering about 5500, almost all on Arizona reservations.
