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