Original Description
Sethophormida (vel Dicyrtida multiradiata aperta) with numerous curved ribs in the wall of the ovate thorax, the small mouth of which is constricted. Cephalis without horn.

Etymology: From the Greek sethamphora = sieve-pitcher"

Extra details from original publication
The genus Sethamphora differs from the preceding Sethophormis, and from the next following ribbed Sethophormida, mainly in the small, more or less constricted mouth; therefore the thorax is more or less ovate, and its ribs curved, with the convexity external. Sethophormis [Sethamphora] may be divided into two different subgenera, Dictyoprora [Dictyoprona] and Cryptocephalus; in the former the cephalis is perfectly free and well developed, in the latter it is more or less hidden in the uppermost part of the thorax (like Carpocanium).

[It may seem, in accordance with ICZN (1961) art. 23(e,i), that this genus should have been called Cryptocephalus Haeckel 1881a, since here in 1887a Haeckel treats Cryptocephalus as a subgenus of Sethamphora and the other subgeneric name used is of a later date. However, this seems inappropriate, since the type species of Cryptocephalus (by subsequent montypy, C. exiguus RĂ¼st, 1885) is not included here in Sethamphora at the time of its generic definition.
