Kuku-Mangk [xmq] is listed in E16/E17/E18/E19/E20/E21/E22/E23 as an extinct separate Middle Paman language. However, out only information regarding Kuku-Mangk ( von Sturmer, John R. 1978: 171-172 , Sutton, Peter John 1978: 168-171 , Ian Smith and Steve Johnson 2000: 358-361 ) says that some informants equate it with Kugu Iiyanh [wij] while others ascribe it a separate identity. But even if the informants giving it a separate identity are correct, they do not necessarily mean that Kuku-Mangk is not intelligible to Kugu Iiyanh or any of the other Kugu dialects. No form-meaning pairs are available to ascertain any variant of the relationship, and thus there is insufficient basis for ascertaining that Kugu-Mangk [xmq] should be a separate entry.
