Careful analysis of early vocabularies of languages surfacing under the name Mayoruna ( David W. Fleck 2013 ) necessitate distinguishing another three extinct languages missing from E16/E17/E18/E19/E20/E21/E22/E23/E24/E25/E26/E27: Mayoruna of the Amazon river ( de Castelnau, Francis 1851 , von Martius, Carl Friedrich Philip 1867 ), Mayoruna of the Jandiatuba river ( de Alviano, Fidelis 1957 ), Mayoruna of the Tabatinga river ( von Martius, Carl Friedrich Philip 1867 ), in addition to the extant Matsés-Mayoruna [mcf] entry. All of them belong to one subgroup of Pano (called Mayoruna) ( David W. Fleck 2013 ). See also: Matsés [mcf].
