Under this family name Scouler places two tribes, the Kalapooiah, inhabiting “the fertile Willamat plains” and the Yamkallie, who live “more in the interior, towards the sources of the Willamat River.” Scouler adds that the Umpqua “appear to belong to this Family, although their language is rather more remote from the Kalapooiah than the Yamkallie is.” The Umpqua language is now placed under the Athapascan family. Scouler also asserts the intimate relationship of the Cathlascon tribes to the Kalapooiah family. They are now classed as Chinookan.

The tribes of the Kalapooian family inhabited the valley of Willamette River, Oregon, above the falls, and extended well up to the headwaters of that stream. They appear not to have reached the Columbia River, being cut off by tribes of the Chinookan family, and consequently were not met by Lewis and Clarke, whose statements of their habitat were derived solely from natives.
