(Smithsonian miscellaneous collections, Vol. 61, Nr. 15; Smithsonian Institution, Publication 2242).This edition is a taxonomic revision of the museum's extensive collection of comatulids. Based on a visit in 1910, Clark documented unnamed specimens, defined new species, and revised established taxa based on earlier work by P.H. Carpenter and F. Jeffrey Bell. Clark reorganized various groupings of stalked and sessile crinoids and defined and established new subgenera such as Florometra. He made detailed notes of previously published data so that specimens were accurately identified according to the standards of marine zoology of the early 20th century.
