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.

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.
