radiolaria - rads_cenozoic - Nephrospyris renilla

Citation: Nephrospyris renilla Haeckel 1887

Taxonomic discussion: Haeckel 1887

Original description: Shell kidney-shaped, one and a half times as broad as long, and three times as long as the deep kidney-shaped sternal incision. Ring with six pairs of branched apophyses, the bars of the apical pair vertical, of the basal pair divergent. The corresponding bars of the two middle pairs (on the frontal and the occipital face) form together on each side a large pentagonal or hexagonal naso-orbital area, which is surrounded by four or five large polygonal meshes; the other meshes become smaller towards the inflated margin. All meshes simple, without arachnoidal framework.
Remarks on original description: Haeckel listed Nephrospyris renilla under the subgeneric name Nephrodictyum, but did not include the subgeneric name in the species name.
Figure description: the text on p.1101 deals with the generic discussion of Nephrospyris in Haeckel, 1887a.
Fig. 7 on pl.90 illustrates Nephrospyris paradictyum in Haeckel, 1887a.[comment from RadWorld database]
