This paper is a revision of the generic nomenclature of a few radiolarian genera whose species are good zone and index fossils. The following genera are revised more or less extensively: Sethamphorus, Sethocephala, Dictyocephalus, Theocampe, and Tricolocampe. The following names are reduced to synonomy: Dictyocryphalus, Cryptocephalus, Dictyoprora (1882), Platycryphalus, Dictyoprora (1887), Theocamptra, Theocampana, Tricolocampium, Tricolocamptra, and Theocampula. Diabolocampe is described as a new genus.
