E16/E17/E18/E19/E20/E21/E22/E23/E24/E25/E26/E27/E28 has an entry Buruwai [asi] which, following Anceaux, Johannes Cornelis 1958 , groups the language of the villages Gaka and Guriasa with the language of villages further southeast such as Kambala and Edor. The two village clusters speak two different but closely related languages, of which the language of Kambala-Edor, also known as South Kamrau, is somewhat more closely related to that of the villages northeast, also known as North Kamrau and represented by the Kamberau [irx] entry. The three are mutually unintelligible (see Walker, Roland 1978: 8 and Timothy Usher and Edgar Suter 2020: 152-153 ) and thus a separate entry for South Kamrau is missing. See also: Buruwai [asi], North Kamrau [irx].
