AbstractThis paper is a revision of Cystoidea specimens collected late in the XIX century, by Drs. J. Almera and M. Faura at several Ordovician outcrops near Barcelona, that are currently inaccessible. These Cystoidea were classified by Ch. Barrois in 189 1 as Echinosphaerites cf. balticus EICHW.a, nd belong to the paleontological collections of the Geological Museums of Barcelona (Museo Municipal & Museo del Seminario Conciliar). The main conciusion of the study is that none of the specimens belongs to Heliocrinites (Echinosphaerites) balticus, but that al1 of them should be referred to Caryocrinites: one specimcn has been clasiified as Caryocrinites aff. europaeus QUENST.a, nd the rest of them should be referred to as Caryocrinites rugatus (FORBES)A. s a result, the geological age of the outcrops must be Ashgil1 instead of Caradoc, as was supposed by M. Faura.
