Hedberg is probably referring to the Kaiy (alternatively called “Taori-kaiy” or “Taori-Kei”) ethnolinguistic group. See: Ethnologue: Languages of the World, 15th edition (Raymond G. Gordon, editor; Dallas: Summer Institute of Linguistics, 2005, p. 416.), which estimates the 2005 population of this group as 220 persons.
