very complex series of ligaments and muscles, which reminds the naturalist of those which unite and move 

 the different segments in the articulated animal. 



The Chiton Chilensis is found in the crevices of rocks, and under stones. Its name is derived from its 

 locality in the neighborhood of Valparaiso, in Chili. 



The Chiton Blainvillii is remarkable for a sort of fringed border. It is found on Inner Lobos Island, on 

 the coast of Peru. 



The Chiton Peruvianus is of a dirty-yellowish green, or yellowish-brown color, inside white. Its border 

 is set with thick, coarse, black hairs. It is found under stones, at low water, in Valparaiso Bay. 



The Chiton Spinosus is found in the South Seas. Its border is wide, and beset with long, sharp, 

 blackish spines. 



The Chiton Spiniferus is found in Chili. It has a thick, broad border, set with blunt spines. 



The Chiton Magnificus grows to the length of five inches. It is found in Chili, often in very exposed 

 situations, attached to rocks beaten by the waves. 



Our engraving of the Chiton Squamosus affords a view of several parts of the animal. In the engraving, 

 u represents the animal and shell, as seen from above ; b the animal seen from below ; c is a side view of 

 the shell and animal, creeping along the rocks, or adhering to them ; and d is a portion of the branchiae 

 magnified. 



In the species Chitonellus the border is highly developed, and the valves very small. They are more or 

 less cylindrical, or vermiform, and the valves being very small, and in some species almost entirely hidden 

 under the skin of the border, give the animal an almost naked appearance. The Chitonellus Lsevis and 

 the Chitonellus Larvseformis are examples of this species. 



The position of the Chitons in the arrangements of the Mollusca, is considered to be near that of the 

 Limpets, (Patella.)
