Original descriptions of taxa. For coccolithophores, and many calcispheres, these are pages from the 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 compiled by Prof A. Farinacci 1969-1989 and updated by Richard Howe 2000-2016 - see also this page.

Editors' Notes

Latin Diagnosis
Cellulae diploideae cum coccosphaera, universe mobilis cum coccolithis monomorphis annularibus ex typo cricolithi. Cricolithi elliptici sine fundo caicareo, ex duobus distinctis elementis alternantibus interordinatis incudi similibus compositi. Annulus distalis plus minusve amplus cure elementis imbricantibus aut non imbricantibus.Generatio pseudofilamentosa hapioidea, sine coccolithis, nonnunquam invenitur.

English translation (from Fresnel & Billard 1991)
Coccolith-bearing cells diploid, generally motile with monomorphic ring coccoliths of the cricolith type. Cricoliths elliptical with no calcified bottom, formed from two distinct, alternating, anvil-shaped elements fitted together. Distal ring more or less developed with overlapping or non-overlapping elements. Pseudofilamentous haploid generation, without coccoliths, present or not.
