Oates (1988:6) lists Kungkakuri (D49) as one of five Muruwari D32 groups, the others being Nuntukuri D50, Kuntakuri D53, Thinuntu D52 and Purukuri D51. It is not clear whether these are also names of distinct language varieties. Radcliffe-Brown (1923:434) mentions Kaŋkargari (D49) and Ŋandugari D50 as being local divisions of the Murawari D32 group which probably spoke different dialects of Murawari. Documentation on Muruwari D32 is relevant.
