AMPHITRITE. 
oyster shell. This animal protruded a snow-white plume, sparingly 
stained with some dark specks. It consisted of about twenty-eight 
feathered branchiz, but was never unfolded, nor shewing more than 
about half an inch. The Amphitrite was always extremely strong. I 
preserved it, in hopes of farther disclosure ; but it disappeared in three 
months, without any visible change, having probably wasted away.—
