E16/E17 lists Kakauhua [kbf] as an extinct Alacalufan language. Caucahue is an ethnonym from colonial sources referring to non-Mapuche (Mapuche [arn], Huiliche [huh]) giant canoemen in the area of the Chonos [-]. There is no linguistic data attributable to Caucahue so the inference that Caucahue is a separate language related to Qawesqar [alc] is wholly illegitimate -- if anything, Caucahue should be equated with Chono on the ethnographic and geographic evidence ( Viegas Barros, Pedro J. 2005 :81 ). See also: Huilliche [huh], Qawasqar [alc], Mapudungun [arn].
