Scallop Shell.

Emblem of St. James of Compostella, adopted, says Erasmus, because the shore of the adjacent sea abounds in them. Pilgrims used them for cup, spoon, and dish; hence the punning crest of the Disington family is a scallop shell. On returning home, the pilgrim placed his scallop shell in his hat to command admiration, and adopted it in his coat-armour. (Danish, schelp, a shell; French, escalope.)
