Original descriptions of taxa. For coccolithophores, and many calcispheres, these are pages from the Farinacci & Howe Catalog of Calcareous Nannofossils. In other cases (e.g. non-calcifying haptophytes) the data is directly compiled on this site. The "Catalogue of Calcareous Nannofossils" was originally compiled by Prof A. Farinacci 1969-1989, since 2000 it has been updated and extended by Richard Howe - see The Farinacci and Howe Catalog - an Introduction.

Original Description

Motile cells with an easily visible (light microscope) scaly covering; encased cells, usually elongated, cylindrical, clavate or fusiform, occasionally ovoid, with flagellar end often obliquely truncate, when without visible scale-covering cells generally pyriform. Cells strongly metabolic; 14-20 (exceptionally 12-24) µm in length, 5-8 (exceptionally 4-9) µm in breadth. Two flagella and one haptonema arising close together centrally from one end; the flagella subequal to equal, smooth, fairly robust, homo- dynamic, 1½-2 times body length; the haptonema, capable of attaching along its whole length, half the thickness of the flagella, commonly 1-2 times body length when fully extended, but occasionally longer than the flagella. Scales in two layers, the lining layer of ovate plate-scales (average dimensions 17 x 1-3 µm), the outer layer of ovate spined scales (spine 1-1.5 µm long on base 1.9 x 1.4 µm), the spine attached to the edge of the ovate base by four arched struts. Terminal spines very large (12-20 µm long on bases c. 2 µm wide), commonly 3 (2-4) at flagellar pole and 5 (3-6) at non-flagellar pole. An inconspicuous group of small two-layered plates (0.8 x 0.5 µm) present near the flagellar bases.

Chromatophores usually two or four, occasionally one, golden brown, oblong sometimes lobed and bifid towards the non-flagellar end, parietal, each with an internal pyrenoid. Lipid and chrysose (leucosin) produced. Ejectile muciferous bodies distributed in peripheral cytoplasm, usually more frequent towards the flagellar end. Nutrition phototrophic and/or phagotrophic.

Non-toxic to fish. In motile phase asexual reproduction by fission into two daughter-cells, usually of equal size; other stages unknown.
