Abstract: The genus Cideina Sirel is characterized by the presence of the orbitoidal lateral chambers on the dorsalside of the shell. Despite of the absence of these lateral chambers, a foraminiferal beast was described and figured as Cideina by Meriç ve İnan. Regarding that the comparisons materials of the authors is very probably a quite differentgenus, the discussion seems to be principally inconclusive. Because of the presence of the orbitoidal lateral chambers onthe dorsal side, Sirtina Bronnimann and Wirz was placed in Lepidorbitoididae by Loeblich and Tappan. Consideringnumerous structural similarities between Sirtina and Cideina, Sirel followed Loeblich and Tappan and placed the Anatolian genus Cideina also in Lepidorbitoididae. In the orginal description, however, Sirel clearly remarked that a distinct family name should be used for such types. These facts also seem to be completely ignored by the authors. On theother hand the name of the type species of Cideina, the terms of the lectotype and paratypes have been used wrong byMeriç ve İnan.
