Names and References; Observations, &c. 




Mariacrinus, Hall. A good genus, closely allied 
to the above, but the two rows of plates in 
the arm separate early, and form distinct 
branches, which again branch, or are rather 
feathered by arms in great numbers. The 
cup is in five pieces. 

Mariacrinus flabellatus, n.s. Named long ago 
by myself in the Fletcher Coll. at Dudley, 
and still unpublished. 
[Actinocrinus, proper, is sure to be found in 
the Wenlock limestone; since we have it 
from the Denbigh flagstone of Wales and 
Westmorland. | 
Platycrinus, Miller. Some little doubt exists 
if this be truly a Platycrinus, since the 
arms are truly simple, not double-jointed. 
Still it is so like, that it is convenient; and 
the species does not belong to Actinocrinus, 
to which it was referred. 
pl. 14, fig. 9). Small cup, the first radials 
large and broad for the size of the creature. 
Plumes short. 
Platycrinus pecten, Salter, n. sp. A much 
larger cup, and long straight comb-like 
plumes to the fingers. 
Glyptocrinus, Hall? Very few plates and very 
short arm-plates. 
Glyptocrinus, sp.1. Like no other crinoid that 
I know. 
Glyptocrinus expansus, Phill. (Siluria, 2nd 
ed. pl. 15, figs. 1, 2). Very doubtfully be- 
longing to this genus. The cup is too 
large, and the series of plates not quite 
exact, as pointed out under G. basalis, in 
p. 45. It is convenient to leave it here 
for the present.
