Definitions
from The Century Dictionary.
- A class of Echinodermata containing globular or cup-shaped echinoderms, having, normally, jointed arms furnished with pinnules, and stalked and fixed during some or all of their lives: so called from the resemblance of their rayed bodies, borne upon a jointed stem, to a lily or tulip.
- The typical order of the class Crinoidea, having the body cup-shaped or calyx-like. the dorsal or aboral surface furnished with hard calcareous plates, the ventral or oral aspect coriaceous, and the body stalked and rooted, at least for some period if not continuously, and provided with five or more radiated segmented arms bearing pinnules and disconnected from the visceral cavity.

-
In the department of zoology, we see, first, traces all but certain of infusoria [shelled animalculæ]; then polypiaria, crinoidea, and some humble forms of the articulata and mollusca; afterwards higher forms of the mollusca; and it appears that these existed for ages before there were any higher types of being.
-
It is true that we first see polypiaria, crinoidea, articulata, and mollusca, but not exactly in the order stated by the author.
-
They abound most in calcareous rocks, which is precisely what might be expected, since lime is necessary for the formation of the shells of the mollusks and articulata, and the hard substance of the crinoidea and corals; next in the carboniferous series; next in the tertiary; next in the new red sandstone; next in slates; and lastly, least of all, in the primary rocks.
