Scallop Scal"lop (?; 277), n. [OF. escalope a shell, probably of German or Dutch origin, and akin to E. scale of a fish; cf. D. schelp shell. See {Scale} of a fish, and cf. {Escalop}.] [Written also {scollop}.] 1. (Zo["o]l.) Any one of numerous species of marine bivalve mollusks of the genus Pecten and allied genera of the family {Pectinid[ae]}. The shell is usually radially ribbed, and the edge is therefore often undulated in a characteristic manner. The large adductor muscle of some the species is much used as food. One species ({Vola Jacob[ae]us}) occurs on the coast of Palestine, and its shell was formerly worn by pilgrims as a mark that they had been to the Holy Land. Called also {fan shell}. See {Pecten}, 2. [1913 Webster]

Note: The common edible scallop of the Eastern United States is {Pecten irradians}; the large sea scallop, also used as food, is {Pecten Clintonius} syn. {Pecten tenuicostatus}. [1913 Webster]

2. One of series of segments of circles joined at their extremities, forming a border like the edge or surface of a scallop shell. [1913 Webster]
