One entry is for the Turkic Khalaj [klj] language -- well known through Gerhard Doerfer 1988 's publications -- which says they also speak Farsi. The other entry Khalaj [kjf] (which has the same population figure and refers to the same ethnic group) is listed in E16/E17/E18/E19 as a separate Iranian language. But in addition to their Turkic language, the Khalaj speak only Farsi [pes], which already has an entry. See also: Khalaj [kjf], Turkic Khalaj [klj].
