Pallets and shells are generally preserved in one part glycerin to tour parts alcohol (70% grain) to permit later study of the delicate cones in the pallets. Permanent slides can be made by soaking the pallets in 90% alcohol for 1 2 hours, then placing on a slide, covering with a few drops of diaphane or euparol, and adding a long slip-cover. Subgenus Bankiella Bartsch 192 1 Bankia gouldi Bartsch Gould's Shipworm Figures i6; 95d New Jersey to Florida, Texas and the West Indies. Pallets about ^ inch in length. Cones deep-cupped, with smooth, drawn- out edges. Cones not very crowded at the distal end. Do not confuse with B. caribbea. Gould's Shipworm is the most widespread and abundant species in this genus on the Atlantic Coast, and hence is the most destructive. It has been found on the Pacific side of the Panama Canal. It is believed that B. inexicana Bartsch is the same species.
