Taxonomy

Citation: Acropyramida, Haeckel 1882 p. 428
Taxonomic rank: family (new classifi
Taxonomic discussion: See Matsuzaki 2015 for concise discussion.

Acro-; Peri-; Bathy-; Cinclo-pyramis are all probably 1 genus and multiple authors have synonymized them in the past.   Foreman 1978 suggests the earliest? name: Cinclopyramis Haeckel, 1879, p. 705. Type species (by monotypy) Cinclopyramis murrayana Haeckel, 1879, p. 705.   Haeckel 1879 is book 'Natürliche Schöpfungsgeschichte' - Not the 1868 series of lectures with similar title. SFAIK not freely available in digital form yet. Until examined not clear if Cinclopyramis validly introduced in 1879, and thus not clear which genus name Should be used for this group. - dl
