ARTIFICIAL KEYS TO THE GENERA OF LIVING STALKED CRINOIDS (ECHINODERMATA)

摘要

Two practical, illustrated, dichotomous keys to the 29 genera of living stalked crinoids are provided: one for entire animals and one for stalk ossicles and fragments. These are accompanied by (1) an overview of taxonomically important morphology, and (2) an alphabetical list by family and genus of the ～95 nominal living species and their distribution by region. This is the first compilation of such data for all living stalked crinoids since Carpenter (1884) recognized 27 species in six genera in his monograph based on the H.M.S. Challenger Expedition collection.
