AS'TRITE
,Noun.
An extraneous fossil, called also asteria and astroit. Astrites are stones in the form of small, short, angular, or sulcated columns, about an inch and a half long, and the third of an inch in diameter, composed of several regular joints, which, when separated, resemble a radiated star.
Astrites are said to be detached articulations of encrinites, a kind of marine polypier.
