Numbers and Localities. 


Cyathocrinus (sp. 7) scoparius, MSS. s. Much 
like the last, but the arms more subdivided, 
and even apparently tufted; and the terminal 
stomach plates appear to have also ended 
in brush-like tufts. 
Cyathocrinus punctatus (Apiocrinus punctatus, 
Hisinger, Leth. Suec. p. 89, t. 25, fig. 2). 
Cyathocrinus (sp.8) Ichthyocrinoides. Like 
young punctatus, but with very short close 
arm-joints, and (smooth? pelvis). 
Cyathocrinus (sp.9) arboreus, MSS. Much 
branched, with round arms and fingers, and 
minute pelvis. 
Cyathocrinus (sp. 11). Like arborens, but 
greatly branched above. 
Taxocrinus, D’Orbigny. Distinguished from 
Cyathocrinus, which it much resembles, by 
the want of any subradial plates; the arms 
are simple, not double; and there are in 
general only a few interradial plates (a) in 
the cup. On the anal side only are those 
interradials brought down to the cup. 
Taxocrinus tuberculatus, Miller (Siluria, 2nd 
ed. pl. 14, figs. 5,6). The commonest species 
of the genus, easily discriminated by the 
strong tubercles all along the plates and 
arm-joints. Specimens of all ages shew 
that young crinoids have much fewer arms, 
or rather fingers, than old ones. 
Taxocrinus tesseracontadactylus, Hisinger, sp. 
(Leth. Suecica, t. 25, fig. 4). It is very 
doubtful if the Zazxocrinus simplex of 
Phillips be not this Swedish species. 
Taxocrinus simplex, Phill. (Sil. Syst. pl. 18, 
fig. 8). 
Taxocrinus marmoratus, Salter, n.s. The 
plates of the cup and the basal portions of 
the arms roughly tubercular.
