Several other languages, of which nothing is known, are said to be spoken in District
Oum Hadjer [at the time in Wadai]. The people speaking them are known to the Arabs as RA TANING, i.e. 'those who speak the strange language'. The names MIGE or míkí, màkú, and mànyáŋ were recorded.
These names have occasionally appeared in language lists as putative Maban languages.[2]
