Contains a map showing the percent location of light colored shells of the Dog Whelk on and around Mount Desert Island Maine. From Introduction, 'Thais (Purpura) lapillus, the purple sea snail or dog welk, has long been distinguished as the most variable member of the littoral formation of the north European and New England coast, and indeed, with its Pacific homologue, of the littoral formation of the whole boreal region. The skeleton or shell is variable not only in color, but also in size, thickness, shape, and sculpture.' /STUDY LOCATIONS:/ /MOUNT DESERT ISLAND/Southwest Harbor/Seal Cove/ /ISLANDS/Greening Island/
