This review is a presentation of progressive knowledge gained on the three subphyla Homalozoa (= Carpoidea), Blastozoa and Crinozoa during the las decade — i. e. after drafting of the manuscripts for the Treatise on Invertebrate Paleontology, vols. S 1(1) and S 1(2) of 1967.Concerning the Crinoidea, the Treatise volume of which has not appeared yet, the accounting period covers two decades.ZusammenfassungFür die drei Subphyla Homalozoa (= Carpoidea), Blastozoa und Crinozoa und damit für das…

Revision of Echmatocrinus from the Middle Cambrian Burgess Shale of British Columbia
Echmatocrinus from the Middle Cambrian Burgess Shale of British Columbia was originally described as the earliest crinoid(?) known from the fossil record. Recently, Conway Morris and Ausich & Babcock
Radiation of Echinodermata
Echinoderms underwent an initial radiation into marine shelf environments in the Early to Middle Cambrian. Within about 45 million years, nine new classes of echinoderms (as recognized in an
In defence of the calcichordates
The present paper answers Philip's criticisms of the calcichordate interpretation and discusses his own proposals and his comments on Ubaghs' views.

SUMMARY “Strobilocystites? kearsargensis Stauffer,” a supposed rhombiferan cystoid from the Kennett Formation, Kearsarge, California, is a diploporite cystoid tentatively assigned to Revalocystis
The Belemnocystitidae; solutan homeomorphs of the Anomalocystitidae
The Belemnocystitidae are Middle Ordovician solutan ("carpoid") homeomorphs of the Anomalocystitidae (mitrate stylophorans) and are characterized by thecae with regu- larized marginal, ventral
On the structure and systematic position of the Genus Rhipidocrinus Beyrich, 1879
A very fine preserved specimen of Rhipidocrinus spec. cf. R. perloricatus W. E. Schmidt, 1905 is described in detail. Special attention in text and figures is drawn to the armstructure. Arms proved
Epizoans on Silurian-Devonian crinoids
Crinoid stems from the Silurian of Gotland and the Devonian of Morocco show a variety of the malformations which in the literature since 1884 have been almost invariably ascribed to myzostomid
New Species of Porocrinidae and Brief Remarks Upon These Unusual Crinoids
Four new species of Porocrinidae include two of Porocrinus and two of the new genus Triboloporus, which seem to have been functional and used in respiration in crinoids.
Bau und Funktion der Scyphocrinites - Lobolithen
In Silurian loboliths (Camarocrinus, bladder-like root of Scyphocrinites) two morphogenetic types are recognized: an older and previously almost unknown ‘cirrus lobolith’, and the familiar

Summary A second specimen of Osculocystis confirms that the genus occurs in the Upper Llandovery (Purple Shales) near Buildwas, Shropshire and adds information on morphology. The subvective system
Cunctocrinus, A New Middle Devonian Calceocrinid Crinoid from the Silica Shale of Ohio
The only calceocrinid crinoid yet discovered in the much studied Silica Shale belongs to a new genus. I t differs from the contemporary Halysiocrinus in having the A-ray radial fused with the B-ray
The types of Roveacrinus alatus, R. communis, and R. rugosus, all of Douglas, are redescribed and reillustrated. A new generic name, Styracocrinus, is proposed for those crinoids formerly referred to
Comparison of comparative morphology clearly indicates the Actinocrinitidae are derived from the Periechocrinitaceae as postulated by Moore & Laudon in 1943, and it is not certain whether the family is monophyletic or polyphyletic.
