Zamba (or Dzamba) is a language of the Ngiri area of DRC ( Motingea Mangulu 1996: 16 , Kamanda Kola, Roger 1991: 1-3 ). Consistent with the impression from sociolinguistics, lexicostatistical figures indicate that Zamba is not intelligible to the varieties around it ( Bastin, Yvonne and Coupez, A. and Mann, Michael 1999: 205 ). The language is missing from E16/E17/E18/E19/E20/E21/E22/E23/E24/E25/E26/E27/E28.
