QUATERNARIELLA obscura gen. et sp. nov. (Prymnesiophyceae) is described on the basis of EM of shadowcast whole mounts prepared from water samples collected in the summer of 1977, at localities in the vicinity of Godhavn, West Greenland. The new taxon comprises small biflagellate coccolithophorids with a short coiling haptonema. The periplast is composed of at least 2 layers of organic scales of which the outer larger circular scales support crystallite packages, each a group of 4 minute rhombohedrons. Small, unmineralized oval scales are present below the coccolith base-plates.
