The name given to a spirit, supposed to reside in the waters. The Shellycoat appears to belong to the class of bogles. When he appeared, he seemed to be decked with marine productions, and in particular with shells, whose clattering announced his approach. He usually ended his mischievous frolics with a horse-laugh.
