Combine crab meat, mayonnaise, parsley, salt, bread crumbs, and beaten eggs; stir gently until well blended. Shape into about 8 crab cakes and refrigerate 30 to 45 minutes. Melt butter in a large heavy skillet over medium low heat; sauté crab cakes until nicely browned on all sides, about 6 to 8 minutes. Serve with lemon wedges or a cocktail sauce.
