SUPPLEMENT 
ON THE 
CLASS CEPHALOPODA. 
THE division of molluscous animals, however numerous in 
species, is so concisely arranged by the Baron, that it has 
been deemed inexpedient to separate his text by inserting 
our own supplementary observations at the end of each class. 
Having translated this portion of the Régne Animal unin- 
terruptedly, we shall proceed in like manner with the supple- 
ments. 
It would be repetition to speak of the class cephalopoda in 
general after our long preliminary article on the division. We 
begin with the genus SEPIA. 
We are chiefly indebted to the ancient writers for all we 
know respecting the natural history of those remarkable mol- 
lusca. Although the species of this genus appear to have 
been rather neglected by zoologists, it would seem that sepize 
are to be found in all parts of the world, and alike in the 
different zones, frigid, temperate, and torrid. 
It is only in the sea that the sepiz exist, but at some dis- 
tance from the coasts, and probably at all depths. They are, 
in fact, along with the calamary, or Joligo, the only animals 
of the molluscous type which may be regarded as not littoral.
