The tribes of this family have been carefully studied by Powers, to whom
we are indebted for most all we know of their distribution. They
occupied the eastern bank of the Sacramento in California, beginning
some 80 or 100 miles from its mouth, and extended northward to within a
short distance of Pit River, where they met the tribes of the
Palaihnihan family. Upon the east they reached nearly to the border of
the State, the Palaihnihan, Shoshonean, and Washoan families hemming
them in in this direction.
