Fig. 2 1 . — Local distribution of the purple starfish, Asierias -vulgaris, whose range, on our coast, extends from Labrador 

 to Cape Hatteras, it being rarely found in shallow water, however, south of Cape Cod. A concentration in the colder 

 waters is here evident, though the distribution in Vineyard Sound is fairly general.
