 With this information, K. Shimizu set out in 1974 to list the languages belonging to the Southern Bauchi Group, to examine their geographical distribution, and to use valid linguistic data to come up with sub-classifications.The survey, published in 1978 and titled "A survey report of The South Bauchi Group of Chadic Languages" came to the conclusion that not all languages listed under the dialect continuum of the South Bauchi Group belonged there and came up with a much more extensive, new classification.This is also the work from which the Barawa subgroup name came from, which was found to be the term used locally in this area to denote the speakers of this dialect continuum.
