The main territory of the Kulanapan family is bounded on the west by the Pacific Ocean, on the east by the Yukian and Copehan territories, on the north by the watershed of the Russian River, and on the south by a line drawn from Bodega Head to the southwest corner of the Yukian territory, near Santa Rosa, Sonoma County, California.  Several tribes of this family, viz, the Kastel Pomo, Kai Pomo, and Kato Pomo, are located in the valley between the South Fork of Eel River and the main river, and on the headwaters of the South Fork, extending thence in a narrow strip to the ocean.  In this situation they were entirely cut off from the main body by the intrusive Yuki tribes, and pressed upon from the north by the warlike Wailakki, who are said to have imposed their language and many of their customs upon them and as well doubtless to have extensively intermarried with them.

KUSAN FAMILY.

  = Kusa, Gatschet in Mag.  Am.  Hist., 257, 1883.

Derivation:  Milhau, in a manuscript letter to Gibbs (Bureau of Ethnology), states that “Coos in the Rogue River dialect is said to mean lake, lagoon or inland bay.”

The “Kaus or Kwokwoos” tribe is merely mentioned by Hale as living on a river of the same name between the Umqua and the Clamet.[65] Lewis and Clarke[66] also mention them in the same location as the Cookkoo-oose.  The tribe was referred to also under the name Kaus by Latham,[67] who did not attempt its classification, having in fact no material for the purpose.
