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

Cells solitary, motile, dorsiventrally compressed metabolic, circular in dorsal aspect, oblong or obovate in lateral aspect, 6.0 x 4.8 x 4.0 µm. Two unequal heterdynamic flagella and a haptonema arising ventrally. An anterior long flagellum, 9-12 µm long, sinuately coiled when at rest, clad with very small spherical knob-scales approx. 0.02- 0.03 µm in diameter. A rudimentary short flagellum, generally flexed backwards and hook-shaped. Haptonema 0. 75 µm proximal expansion and 1 µm distal extension.

Chloroplasts, one parietal, yellowish green, markedly two lobed: Without pyrenoid and stigma. Nucleus anterior. Two vacuoles with reserve materials in the posterior part of the cell.
