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 
^ distant analogy to those parts in the organiza- 
tion of superior animals from which they have 
lieen denominated. A similar system of plates, 
* “ On the summit of the vertebral column are placed succes- 
sive series of little bones, see PI. 50, Fig. 4, which 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 PI. 48. PI. 49. Fig. 1. PI. 50, Figs. 1, 2), having 
fbe mouth in its centre, and containing the viscera and stomach 
of the animal, from which the nourishing fluids were admitted to 
un alimentary cavity within the column, and also carried to the 
urms and tentaculated fingers.” From the scapula (H) proceeded 
*^lre five arms, (PI. 50, Fig. 1, K) which, as they advanced, sub- 
divided into hands (M) and fingers (N) terminating in minute ten- 
fucula (PI. 50. Figs. 2, 3), the number of which extended to many 
thousands. These hands and fingers are represented as closed, 
or nearly closed, in PI. 48. and PI. 49, Fig. 1. and PI. 50, Figs. 
1,2. In Mr. Miller’s restoration of the Pear Encrinite (PI. 47, 
^Ig. 1) they are represented as expanded in search of food. These 
tentaculated fingers, when thus expanded, would form a delicate 
uet, admirably adapted to detain Acalephans, and other minute 
uiolluscous animals that might be floating in the sea, and which 
probably formed part of the food of the Crinoidea. In the centre 
uf these arms was placed the mouth (PI. 47, Fig. 1), capable 
of elongation into a proboscis. PI. 47. 6, x. 7, x. represent the 
bodies of Crinoidea from which the arms have been removed. 
In PI. 50, Fig. 1 represents the superior portion of the animal, 
''vith its twenty fingers closed like the petals of a closed lily, 
I^*e- 2 represents the same partially uncovered, with the tentacula
