 Gavan Breen provisionally includes Minkabari and the 'Ngura' dialect Pitjara/Bidjara/Bitharra, which together have been called the Bulloo River language.Gavan Breen is partly responsible for the variation in the spelling of the name 'Kalali'.The forms "Garlali" and "Galarli" are due to what he now considers a non-distinctive instance of retroflex "rl", and he prefers the spelling "Kalali".
