This volume, originally published in 1970, presents a survey of the languages spoken in an area extending from the Atlantic coast at the Sengal River eastward to the Lake Chad region. The area covered by this volume is mainly a goegraphical one, so it follows that not all the languages included are related to one another, though a certain degree of homogeneity appears.
