(A dim. of corallium, coral,) mus-cus marinus, corallina anglica, corallina alba, sea coralline, and white wormseed.

It is a marine production, common on rocks and shells in shallow water. It resembles a small plant without leaves, consisting of several jointed branches, generally of a greyish colour, sometimes greenish, yellowish, or reddish; of a brittle stony substance, friable betwixt the fingers, and crackling between the teeth. It hath commonly been supposed a vegetable; but is really of animal origin, and the habitation of an animal belonging to the class of polypi. The corallines formerly were a very extensive groupe, including the tubulariae sertulariae, the alcyones, sponges, etc.; but we are indebted to Ellis for more correct ideas, and more accurate distinctions. For the corallina officinalis, see Ellis, Pi. 24, Fig. A. Its height is about two or three inches.

It ought to be entire, of a strong sea smell and salt taste. Worms will live in a strong infusion of it for several days, notwithstanding it has been styled an anthelmintic. By calcination in a strong fire, it becomes true quicklime, and consequently resembles other testaceous marine bodies. See Neumann's Chem. Works, Lewis's Mat. Med. Cullen's Mat. Med.

Corallina helmintho corton, a species of con-serva, found chiefly in Corsica, and employed as an anthelmintic.
