CLASS III. GASTEROPODA. ORDER II. CYCLOBRANCHIATA. 13 
Chiton fasciatus (Plate CXXXV. Fig. 3, 4 and 5), recently brought from 
the Philippine Islands by Mr. Cuming, the mantle is of enormous size in 
proportion to the body of the animal ; the valves of the shell are distant 
from each other, and the species altogether is highly characteristic. 
The Chitonellus may be described as being elongate, worm-shaped, and 
furnished with eight testaceous valves ; the valves are longitudinal, dis- 
joined, and inserted, independent of each other, along the back of the 
mantle ; they approximate towards the anterior end, and are deeply im- 
bedded within the substance of the skin, which is thick and generally 
coriaceous, often sparkling, when dried, like congealed frost.
