The following new silicoflagellates are described from the Palaeocene and Early Eocene diatomite at Fur, Denmark, and the Late Eocene diatomite on Voering Plateau, Norwegian Sea: Corbisema ova/is, Distephanus norvegiensis, D. rosae, Mesocena concava, Naviculopsis danica, N. punctilia and N. vemae. Species of Navicu/opsis, Corbisema and Dictyocha serve to define seven local silicoflagellate subzones: The N. constricta, N. danica, D. elongata,, C. naviculoidea and the N. aspern subzones in the Palaeocene and early Eocene of Denmark and the N. vemae and N. punctilia subzones in the Late Eocene of the Norwegian Sea.
