T. polybotrys sp. nov. (Prymnesiophyceae) is described on the basis of EM shadowcast whole mounts prepared from water samples collected in the summer of 1977, at localities in the vicinity of Godhavn, western Greenland. The spherical cell has 2 smooth flagella and a somewhat shorter haptonema. The periplast is composed of coccoliths which are goblet-shaped over most of the cell surface. Coccoliths around the flagellar pole are basically similar but unilaterally enlarged. The crystallites are hexagonal plates. An underlayer of small, unmineralized scale is found below the coccolith base-plates.
