Pecten islandicus (MuUer). 

 (The Arctic scallop. ) 



Casco Bay to Eastport. 

 Pecten magellanicus, Gmelin. 



Pecten tenuicostatus, Mighels, 1842. 

 Chlamys clintonius, Verrill. 

 (The Maine, Great or Giant scallop.) 

 Casco Bay to Eastport. 

 This is the largest Pecten on the Atlantic coast, attaining a 

 very large size, a specimen from Portland Harbor, and now in 

 the Portland museum, measuring 6 11-16 in length by 73-16 in 

 width. The abductor muscle, called by the fishermen the "eye" 

 or "heart," of the scallops, both the common and Maine species, 

 is largely used for food. "Scalloping," or taking the scallops 

 in dredges, is no inconsiderable industry on the Maine coast, 

 pursued by many fishermen. 

 Pecten pustulosus, Yerrill, 1873. 



Gulf of Maine, 115 to 150 fath. (V'errill).

 clam, it is quite palatable. 

 Mytilus edulis var. pellucidus. Pennant. 

 (Rayed or translucent mussel.) 

 Found in company with the type species, but not nearly as 

 abundant. 



Modiolus modiolus, (Linne). 

 (Red or horse mussel.)
