Merriam indicates three groups: the Northern, Central, and Southern.

The Northern he lists as Mitchopodo and Notokoiyo, the Central as Kon-kow or Timah, Tahn-kum, Kow-wahk, and Kum-mo-win, the Southern (Nissenan) as To-sim-me-nan, Ho-mah, Nis-sim Pa-we-nan, and Nis-se-nan (page 16).

 The Kon-kow or Timah - just east of the Michopdo - a foothill tribe extending north to Yanah, south to Oroville and east to North Fork Feather River (page 16). The Tahn-kum (may be band of Kon-kow) - north of Honcut region (page 17).

 Kow-wahk - foothills between American River (north of Notomusse and Nis-sim Pa-we-nan) and Yuba River and on northeast to include French Corral, San Juan and Challenge and up into and over Sierras south of Kom-mowin to Middle Fork Yuba Region (page 17).

 Kum-mo-win - drainage of Middle Fork Feather River and South Fork Feather River. West to North Fork Feather River; (Mooretown and Enterprise dialects slightly different) east to Mohawk Valley (Blairsden) (page 17).
