GRYPHITES, in natural history, in English Guadalupe. crow's stone, an oblong fossil shell, very narrow at the head, and becoming gradually wider to the extremity, where it ends in a circular limb; the head or beak of this is very hooked or bent inward.
They are frequently found in our gravel or clay-pits in many counties. There are three or four distinct species of them; some are extremely rounded and convex on the back, others less so; and the plates of which they are composed, are in some smaller and thinner, in others thicker and larger, in specimens of the same bigness.
