A. L. Kroeber has contributed to Hokan studies to an extent not usually recognized by nonspecialists. Together with Dixon, he first discovered the genetic relationships of the group, then consisting of Karok, Chimariko, Shastan (including Palaihnihan), Pomo, Yana, Esselen, and Yuman. He later added Seri, Tequistlatec (cf. Kroeber), and (with Dixon 1919) Washo. Kroeber has also contributed important fieldwork: Sapir's early comparative work leans exclusively on Kroeber's data for Chontal, Chumash, Salinan, and Esselen, and heavily on Kroeber's data for Yuman, Pomo, Karok, Shasta, Achumawi, and Atsugewi. Kroeber and other Hokanists have long noted the paucity of data from Achumawi and Atsugewi; the present paper is a result of field work undertaken at his suggestion.
