144 CLASS IV. 
Genera: Caryocrinites Say, Platycrinites MILL, Actinocrinites 
Mitu., Rhodocrinites Mitu., Cyathocrinites MILL., Poteriocrinites 
Mitt., Melocrinites GOLDF. 
For these fossil genera and others unnoticed we must for want 
of space refer to Mriur’s work already cited, to Goupruss die 
Petrefacten Deutchlands, and other geological works. Comp. also

ornatus in his work Ueber Cystideen, Berlin, 1845, 4to. 
In these and the following pediculate Crinoids, the cup-like part 
at the extremity of the stem and base of the arms is named Calyz. 
The bottom of this part, which is pentangular, and composed of five, 
four, or sometimes three plates, is named by Miter pelvis ; Jou. 
MUELLER names the plates basalia; at the margin of these plates 
are the basal-pieces of the arms, forming the uppermost part of the 
calyx ; there are two or three rows, and the uppermost bears the 
arms. MILLER gives to this part the name of scapula; the two 
pieces situated below are coste. Jou. MUELLER names these pieces 
radialia (radiale primum, r. secundum and r. axillare; his radiale 
axillare is the scapula of the English author). In those now 
named Crinoidea tesselata these parts are joined together without 
articulation. The fossil species of this division are found in the 
transition-limestone and the grey-wacke. 
** Articulata. The rays free directly from the pelvis of the 
calyx, the first radial conjoined to the second, and the second 
to the third by articulation. 
Apiocrinites Mitt. Column incrassated towards the calyx, 
pyriform. 
Sp. Apiocrinites rotundus Mitu. Tab. I-—vit. Apiocrin. Parkinsonit BRonn, 
Lethea Tab. xvii. fig. 15, (MILLER’s figure) fossil from the oolite forma- 
tion, like other species of this genus. 
Encrinus GUETTARD (in part). Column round, not incrassated 
towards the top. 
Sp. Encrinus liliiformis Lam., Encrinites moniliformis MILLER, pp. 37—44, 
Tab. 1—111. ; Exuris Corall. Tab. 37, fig. kK, &c. One of the most character- 
istic fossils of the Muschelkalk. The head, on account of the numerous 
articulations of the arms that lie side by side, resembles an ear of Turkish 
wheat (Zea Mays) ; the joints of the stem, sometimes found in incredible 
numbers, changed into calcareous spar, are named T'rochites?.
