Geschichte dieser Gattung (BiUings 1856, Zittel 1879, Wachs- 

 muth and Springer 1879, Bather 1900), Beschreibung der vor- 

 hegenden Exemplare, darunter Billings's Typen, Struktur des 

 Calyx und der Arme. Letztere sind pinnulifer. Basis sehr ein- 

 gehend beschrieben. Cleiocrinus dürfte mit Reteocrinus verwandt 

 sein und läßt sich folgenderweise definieren: ,, Calyx large, conical 

 or pyriform; pliant; plates joined by loose suture. Base dicycUc; 

 infrabasals five, invisible exteriorly. Basais and radials not in 

 normal succession, but alternating with each other in a horizontal 

 ring of ten plates surrounding the infrabasals and projecting 

 down ward over the column. No interbrachials, except at the 

 anal side; anals in vertical series, resting on truncate posterior 

 basal, and extending high up between the rays. Rays and their 

 divisions up to the free arms contiguous and interlocking ; brachials 

 bifurcating several times in the calyx, giving off fixed pinnules, 

 which are incorporated by lateral imion with adjacent brachials 

 and become free between the arm bases. Arms simple, uniseriate 

 and pinnulate. Column obtusely pentagonal or nearly round". 

 Die beiden Arten der Gattung (C. regius Bill, und magnificus 

 Bill.) werden beschrieben; Cl. grandis Bill, ist ein Synonym von 

 Cl. regius. — An der Tafel, des Vergleiches willen, auch dargestellt 

 Glyptocrinus Dyeri Meek und Reteocrinus O'Nealli Hall.
