Class CARPOIDEA

Order SOLUTA

First, Ord ?Tremad: Undetermined Dendrocystitid, probably L. Tremad (Ubaghs 1963b).

Last, Dev Gedinn-Siegen: Rutroclypeus junori Withers, R. victoriae Gill and Caster, R. withersi Gill and Caster, Victoria, Australia; or "Rutroclypeus" globulus (Dehm) Dev Siegen, Germany (Dehm 1934, Gill & Caster 1960).

Last, Ord Ashg: Cothurnocystis elizae Bather, C. curvata Bather, Scotland (Bather 1913).

Order MITRATA

First, Ord Tremad-Arenig: Peltocystis cornuta Thoral and Chinianocarpos thorali Ubaghs, U. Tremad or L. Arenig, S. France (Thoral 1935, Ubaghs 1961).

Last, Dev Eifel-Givet: Dalejocystis casteri Prokop, Bohemia (Prokop 1963).

Last, Ord Carad: R. robusta Hecker, M. Carad, Leningrad region, U.S.S.R. and Estonia (Hecker 1940).

Class CYCLOIDEA

First and and Last, Camb M. Camb: Cymbionites craticula Whitehouse (1941), Queensland, Australia. It is probably an Eocrinoid.

Class CYAMOIDEA

first and Last, Camb M. Camb: Peridionites navicula Whitehouse (1941), Queensland, Australia.

Comment: Probably an Eocrinoid or digitate "carpoid" related to Rhipidocystis.

Class HELICOPLACOIDEA

First and Last, Camb L. Camb: Helicoplacus curtisi, H. gilberti Durham and Caster, California, Nevada (U.S.A.), Alberta (Canada). (Durham & Caster 1963, Durham 1964).
