Current identification/main database link: Archiperidium Haeckel 1881

Original Description
Archiperida (vel Monocyrtida triradiata clausa) without internal columella, with an apical horn.

Etymology: From the Greek peridium = small pouch"

Extra details from original publication
The genus Peridium (or Archiperidium, Prodromus, loc. cit.) and the two following nearly allied genera form together the small group of Archibursida, differing from the four preceding genera (the Euscenida) in the absence of an internal free columella. The three basal feet have therefore no direct connection with the apical horn. Peridium, the ancestral form of the Archibursida, may have originated either from Euscenium by reduction and loss of the columella, or directly from Tripospyris by loss of the sagittal ring and the longitudinal constriction.

[By referring back to p.429 of his Prodromus and stating above ""Peridium or Archiperidium" Haeckel obviously means Peridium to be an emendation of the name Archiperidium, which is unjustified according to the ICZN (1961) art. 33a. Peridium is thus a junior objective synonym of Archiperidium Haeckel 1881a.
Description: The ""two following nearly allied genera"" refers to Archipera and Archibursa; the ""four preceding genera"" refers to Euscenium, Cladoscenium, Archiscenium, and Pteroscenium in Haeckel, 1887a.]
