Excerpt from The North American Crinoidea Camerata
Fig.1 is a joint of Pentacrinus; fig. 2 of Rhizocrinus. The stem fragment, fig. 3, belongs to mespilocm'nus figs. 5, 8, 9, 11, and 12 to Platycm'nus fig. 6 to Teleiocrinus, and fig. 7 to Cactocrinus. The specimen fig. 10, which probably belongs to an Actinocrinus, shows beautifully the striations at its upper face, and fig. 13 the connection of the cirrus canal with the stem canal.
