The purpose of this volume is to list all systematically treated or illustrated Paleozoic Crinoidea for the years 1986 through 1990. Initially it was planned to include the Coronate Echinoderms; however none were illustrated or systematically treated during the 1986 through 1990 interval. Although I do not agree with the identification of many of the species or genera as indexed, I am not attempting to reassign them. I leave that up to later workers who are systematically treating the species involved. I hope that this compilation facilitates their work as it does my own.
