[This is from the root of shell, scale; coinciding with scalp.]

1. A shell fish, or rather a genus of shell fish, called pecten. The shell is bivalvular, the hinge toothless, having a small ovated hollow. The great scallop is rugged and imbricated with scales, grows to a large size, and in some countries is taken and barreled for market.

2. A recess or curving of the edge of any thing, like the segment of a circle; written also scallop.
