Shell consisting of several valves, arranged longitudinally on the 
back of the animal. 
THE genus Chiton ranks first in the classification 
of shells, and no less than forty species are known; 
some of which are beautifully marked, and some of 
rare occurrence. From the peculiar appearance of 
this multivalve, it is impossible to confound it with 
any other genus; and it may be observed, that all 
the species closely approximate each other.
