In fish markets, there are specialist names for different sizes of this species of clam. The smallest legally harvestable clams are called countnecks or peanuts, next size up are littlenecks, then topnecks. Above that are the cherrystones, and the largest are called quahogs or chowder clams.

Rhode Island is situated right in the middle of “quahog country” and has supplied a quarter of the U.S.’s total annual commercial quahog catch. The quahog is the official shellfish of the U.S. state of Rhode Island. From Wikipedia.org
