Some additional Kazukuru data and the only information on Dororo and Guliguli (two short wordlists) were published by Peter Lanyon-Orgill in 1953. Davis (2003) is skeptical that Guliguli ever existed, since the word  has an obscene meaning in the neighboring Hoava language, and there is no memory among Hoava speakers of a neighboring language with that name.
