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.

Figures i6; 95d
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.
