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.
Taxa are sorted alphabetically for simple browsing, or you can use search boxes at the top & bottom of the page

Original Description
Description. The small subspherical cell has two flagella and a slightly shorter hapto- nema (PI. VI A). The scales are of two types. The underlying scales are oval flat plates displaying an arrangement of approximately concentric ridges dominated by radiating ridges equally visible on both surfaces (PI. VIB). The outer layer of circular scales are similar in patterning and construction to the underlying oval plates (PI. VI c). The margin of the distal surface is distinguished by a flap of scale material which, in whole mounts, appears to collapse inwards on to the surface of the scale. Sections are required to deter- mine the precise relationship between the scale and margin.

Extra details from original publication
The dimensions of the protoplast have been estimated from cells, similar to that shown in PI. VIA, by measuring the length and width of the scale case. This makes some allowance for shrinkage of the protoplast encountered during the ' drying down' process (see Manton & Leadbeater (1974) for further details of this problem).
