Original Description
Porodiscida with a simple central chamber, surrounded by a single concentric ring, which is divided by radial beams into two to six or more radial chambers, without radial spines on the margin.

Etymology: Greek archidiscus = primordial disk"

Extra details from original publication
The genus Archidiscus begins the long and polymorphous series of the Cyclodiscaria or of those Discoidea which do not possess the peculiar “phacoid shell"" characteristic of the three preceding families, united as ""Phacodiscaria”. As already mentioned above, both these groups are probably of independent origin, derived from the Sphaeroidea in different ways (compare pp. 402, 405, &c.). Among all Cyclodiscaria Archidiscus is the most simple, and probably the common ancestral form, from which the other genera may be derived.

The text on p.402, 405 etc. deals with the suborder Discoidea and is not included herein.
