PLACE OF CRINOIDEANS. 417 
limestone near Bristol, are well known examples 
of strata thus composed ; and show how largely 
the bodies of Animals have occasionally con- 
tributed by their remains, to swell the Volume of 
materials that now compose the mineral world. 
The fossil remains of this order have been long- 
known by the name of Stone Lilies, or EncriniteSy 
and have lately been classed under a separate 
order by the name of Crinoidea. 
This order comprehends many Genera and 
numerous Species, and is ranged by Cuvier after 
the Asteriae, in the division Zoophytes. Nearly 
all these species appear to have been attached to 
the bottom of the Sea, or to floating extraneous 
bodies.* 
The two most remarkable Genera of this family 
have been long known to Naturalists by the 
* These animals form the subject of an elaborate and excellent 
work, by Mr. Miller, entitled a Natural History of the Crinoidea, 
or Lily-shaped Animals. The representations at PI. 48, and PI. 
49, Fig. 1. of one of the most characteristic species of this 
family, being that to which the name of stone-lily was first ap- 
plied ; and the figures of two other species at PI. 47, Fig. 1,2,5, 
will exemplify the following definition given of them by Mr, 
Miller. " An Animal with a round, oval, or angular column, 
composed of numerous articulating joints, supporting at its 
summit, a series of plates, or joints, which form a cup-like body, 
containing the viscera, from whose upper rim proceed five articu- 
lated arms, dividing into tentaculated fingers, more or less nume- 
rous, surrounding the aperture of the mouth, (PI. 47. Figs. 6, x- 
7, x) situated in the centre of a plated integument, which extends 
over the abdominal cavity, and is capable of being contracted 
into a conical or proboscal shape."
