E16/E17 lists Imeraguen [ime] as an unclassified language of Mauretania spoken by an ethnic group traditionally subsisting on fishing. Presumably based on a blanket statement by Gerteiny, Alfred G. 1967 :56 , E16/E17 reports that it is ``Reportedly a variety of Hassaniyya structured on an Azer (Soninke) base''. However, it is unclear what Gerteiny, Alfred G. 1967 :56 's statement is based on and no data or other evidence for the Azer-Ḥassāniyya mix is adduced. Other ethnographers with field experience, notably Fortier, Corinne 2004 , say they speak Ḥassāniyya with some special vocabulary related to fishing. The specific forms of the fishing vocabulary are cited and they clearly derive from a Berber (not Azer) source, and there is no ethnohistoric evidence for an Azer origin either ( Fortier, Corinne 2004 ). Since there is insufficient evidence to posit a past or present separate language for the Imraguen, the entry is spurious.
