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
Chromatophores two, saucer-shaped at the lateral-anterial side of the cell body. A pyrenoid in the middle part or near the end of the chromatophore. Lucosin smaller at the body end opposite to the flagella. Cells swim relatively smoothly to the opposite direaion of the flagella. Nutrition autotrophic and/or phagotrophic.
Two kinds of scales on cell, the large ones like oval to round saucers, 0.73x0.5 - 0.82x0.6 µm in diameter , one side with tetraradiate sculptures; other side smooth, its margin broad (ca. 0.028-0.035 µm), without sculpture. The small scales, round to oval shaped, 0.38x0.31 - 0.43x0.36 µm in diameter, with same sculptures as that on the large scales, its margin about 0.03 µm wide.

Extra details from original publication
Manton (1967) reported Chrysochromulina chiton var., which appeared different in scale formation from C. chiton, and established it as a synonymous specimen of C. chiton; the sizes of its scales were between C. chiton Parke et Manton and this new variety C. chiton var. minuta, and the morphology of the former was somewhat similar to the latter (this new variety).
