Considerable amounts of skeletons ofD. spinosa (Defl.) Gleser were found by us in the Lower Oligocene (?) deposits of the southern part of the Taz peninsula. In addition, this silicoflagellate has been reported from the Late Eocene —Early Miocene deposits of Barbados Island (Lesser Antilles). The latter form is known from the Late Eocene of the basin of the Irgiz River, the Late Oligocene of the Mangyshlak peninsula and Austria. (188. FIGURE 12.
