Paperback. Condition: New. Print on Demand. This book catalogs every known species and higher group of living comatulids, scientifically classifying these marine invertebrates in accordance with a system derived largely from the work of the author. The classification used in the book, which covers all 587 species and 100 genera of comatulids, is traced from its inception in 1907 to its final form, achieved by 1910, when the last of the 10 parts was published as part of Volume 1 of the Bulletin of the United States National Museum. Included is an account of the interrelationships of the comatulids and other echinoderms, and a detailed discussion of the homology of the post -radial elements in the comatulids.
