Syn., Apiocrinites (Hisinger) in part ; Millcricrinus (d'Orbigny) in part. 



In 1850 d'Orbigny established this genus to receive two 

 species, which had been noticed and figured by Hisinger as 

 Apiocrinus scriptus and A. punctatus. Only the calj'x was then 

 known, and the generic definition simply stated that this was 

 composed of five depressed basals, five large " subradials " and 

 five "brachials." He placed the genus in the family Melocrinidae, 

 while Pictet, and also Dujardin and Hupe, referred it to the 

 Cyathocrinidae. Angelin makes it a distinct family, and Zittel 

 considers it as belonging to the Crotalocrinidffi. It is clearly 

 separated from the Inadunata by the fact that its radial divisions 

 are connected either by direct union or by interradial plates 

 between the secondary radials. Although Angelin, in his defini- 

 tion of the genus (Icon. Crin. Suec, p. 25), states " interradialia 

 nulla," his figures demonstrate their undoubted presence both on 

 the dorsal and ventral side (PI. xv, figs, la, 3a; PI. xxv, figs. 4, 4a). 

 It appears from these illustrations that in some cases the corres-
