tions of the individual forms and uses of each 
successive series of plates.* 
From the subjoined analysis of the component 
portions of the body of the E. Moniliformis, we 
see that it may be resolved into four series of 
plates each composed of five pieces, and bearing 
a distant analogy to those parts in the organiza- 
tion of superior animals from which they have 
been denominated. A similar system of plates, 
* *' On the siimmitof the vertebral column are placed succes- 
sive series of little bones, see PI. 50, Fig*. 4, v.'hich from their po- 
sition and uses may be termed the Pelvis E, Scapula H, Costal F, 
forming (with the pectoral and capital plates) a kind of sub-glo- 
bular body (see PL 48, PI. 49, Fig. 1. PL 50, Figs. 1,2), having 
the mouth in its centre, and containing the viscera and stomach 
of the animal, from which the nourishing fluids were admitted to 
an alimentary cavity within the column, and also carried to the 
arms and tentaculated fingers." From the scapula (H) proceeded 
the five arms, (PL 50, Fig. 1, K) which, as they advanced, sub- 
divided into hands (M) and fingers (N) terminating in minute ten- 
tacula (PL 50, Figs. 2, 3), the number of which extended to many 
thousands. These hands and fingers are represented as closed, 
or nearly closed, in PL 48. and PL 49, Fig. 1. and PL 50, Figs. 
1, 2. In Mr. Miller's restoration of the Pear Encrinite (PL 47, 
Fig. I) they are represented as expanded in search of food. These 
tentaculated fingers, when thus expanded, would form a delicate 
net, admirably adapted to detain Acalephans, and other minute 
molluscous animals that might be floating in the sea, and which 
probably formed part of the food of the Crino'idea. In the centre 
of these arms was placed the mouth (PL 47, Fig. 1), capable 
of elongation into a proboscis. PL 47, 6, x. 7, x. represent the 
bodies of Crino'idea from which the arms have been removed. 
In PL 50, Fig. 1 represents the superior portion of the animal, 
with its twenty fingers closed like the petals of a closed lily. 
Fig. 2 represents the same partially uncovered, with the tentacula
