North of Cape Ann this largespecies is of common occurrence in moderately deep water. The deeperbays and arms of the sea which everywhere penetrate the Maine coastare its favorite resorts. A good way to catch pectens is to lower a fishing-line at a spot where the fishermen report scallop-ground, and drag italong over the bottom. Sooner or later it will enter the open shell ofsome pecten, which will instantly close its valves upon the string andallow itself to be drawn out of the water. In Maine these large scallopsare eaten, but they have not found great favor in the city markets. Incolor they vary from reddish through brown to ashen. P. islandicus. A species not so large as the last, with more promi-nently raised ribs (about fifty to one hundred in number), which are cov- PELECYPODS 437. ered wit h a multitude of erect scales. The ribs persist upon the interior ofthe shell. The ears are unequal in size. The color is light orange toreddish-brown, with zonesof darker and richer col-or. One valve is flatterthan the other and morelightly colored. Greatestlength about three inches;height three and a halfinches. This is a Northernshell, belonging to thewaters of Newfoundland,but its valves are fre-quently cast upon the NewEngland beaches. P. iiTiiftitnis. Thecommon shallow-waterspecies of the Atlanticcoast.

This is the true scallop of the Boston and New York markets. Only the adductormuscle is eaten. In this species there is not so marked a difference inthe convexity of the two
