Abstract: In this study; some new observations are discussed on Cideina soezerii (Sirel) identified in the UpperMaastrichtian outcrops around the Niksar, Reşadiye, Koyulhisar, Elazığ and Malatya areas in Turkey. The tests surfacesof this foraminifer are ornamented by honeycomb shaped hexagonal hols, but notwith net like figures. This teststructure, trochospiral coiling and ombilical fillings suggest that this genus be identified in the Rotaliidae family, butnot in the Lepidorbitoididae family as assumed by Sirel (1991). Lectotype and paratypes are shown on plates.
