Cheirocrinus Fletcheri, n.s. (C. sp. branched | a. 388, Dudley, F. C. 
arm) Fletcher Coll. Siluria, 2nd ed. App. 
p. 535. The finest and most curious of 
all the species. It has repeatedly branched 
nodose arms, and is the largest of all, and 
will shew us the affinities with other genera | 
at present obscure. 
FC 
b. Crinoids with double rows of plates in 
the arms. 

Marsupiocrinus, Phillips. The arrangement 
of the plates in the broad cup is that of 
Eucalyptocrinus, Goldfuss, and of Hypan- 
thocrinus. But the proboscis is not gigantic 
and solid as in the latter genus: and we 
do not know enough of Goldfuss’ figured 
genus. 


FC p. 54. Marsupiocrinus celatus, Phill. (Siluria, 2nd ed. | a. 667, with Pseudocrinus ; 
Gd pl. 14, fig. 1, and p. 247, woodcut 55, figs. | a. 389, Dudley, F.C.; a. 
1—3). A fine series, shewing young and | 390, feeding on Acroculia, 
old cups, arms, interior of arms, stomach | Dudley, F. C.; a. 391, 
surface retracted in rest, or produced into | Dudley, interior of arms, 
proboscis for feeding on the Gasteropoda, | Ketley Coll.; casts of Gray’s 
Mr John Gray found that Actoculia Ha- | specimens (Brit. Mus.). 
| liotis was the favourite food. See woodcut 
in Siluria, Foss. 55, as above. 

Syriocrinus, Hall. Very much resembles Mar- | 
suprocrinus, if it be not the same genus. 

Hypanthocrinus, Phillips (Sil. Syst.), Zucalyp- 
tocrinus, Salter, &¢. in Siluria, 2nd ed. 
There is no ground for so altering the gene- 
ric name: though I myself was the first to 
propose it. The Devonian genus has a 
much shorter calyx, and several genera 
are now found to have the conspicuous 
star-like arrangement of plates round the | 
interradials b.
