CHITON.—Puate XII. 
Easily recognised by the marked contrast between the 
colouring of the shell and the scales of the ligament; a 
character which I take to be permanent.

Hab. . 
This very interesting species, the valves of which have 
somewhat the form of those of C. setiger, is distinguished 
by a most elaborate close-grained latticed style of sculpture, 
perfectly distinct from any that I have yet met with. Mr. 
Sowerby’s name exists only in manuscript, but I have 
much pleasure in giving publicity to it, for the sake of 
honouring one of the most intelligent conchological travel-. 
lers recorded in the history of our scientific Expeditions.
