Combine green pepper, 1 cup mayonnaise, eggs, mustard, pimiento, salt, and pepper in a large mixing bowl; mix well. Add crab meat; mix gently so that lumps are not broken.
Place 8 crab shells or 6-ounce custard cups on a 15- x 10- x 1- inch jellyroll pan. Spoon 1 cup crab meat mixture into each shell. Top evenly with remaining mayonnaise; sprinkle with paprika. Bake at 350° for 15 minutes. Serve hot or chilled.
