Extract

The new genus here proposed is based on nine specimens. All are more or less complete crowns. The best preserved example (Plate III, figs. 1, 2, 3, 5) was previously illustrated in Trans. Roy. Soc. Edin. as Synerocrinus incurvus (Trautschold) (Wright, 1939–1940, pl. xi, fig. 8). Later, the discovery of another well-preserved specimen caused some doubt about this interpretation and led to further cleaning and developing not only of the first mentioned specimen, but of others in my collection. Some of these were labelled as Synerocrinus incurvus (Trautschold) or the kindred species Amphicrinus scoticus Springer. From a study of all these specimens it is now evident that we are here dealing with a crinoid which differs in certain aspects from Synerocrinus or in fact from any other described Ichthyocrinid. Two specimens previously figured as Amphicrinus scoticus Springer (Wright, 1914, pl. xix, fig. 4, 1939–1940, pl. xi, fig. 2) are now here referred to the new genus.
