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, mostly asymmetric knife-shaped, 10–16 μm long, 3–6 μm wide. Two equal to subequal flagella, 14–26 μm, inserted at the cell apex. Haptonema 4–10 μm, noncoiling. Cells covered by two types of scales. Scales of the inner layer elliptical, 0.35 × 0.18 μm, with a narrow inflexed rim, and a radial pattern. Scales of the outer layer rhomboidal, 1.1 × 0.6 μm, with upright rim (50–80 nm), two projections, and a radial pattern. Rhomboidal scales do not overlap. Two pale yellow chloroplasts, lateral and parietal, are displaced horizontally, each with an immersed pyrenoid. The flagellar transitional region with a terminal transitional plate.

Size:

Etymology:
The generic name refers to the colour and unique asymmetrical cell shape (chryso = golden, culter = knife)
