own seas. It is chiefly remarkable for the chalky internal skeleton, commonly 
called Cuttle-bone, and much used for the manufacture of tooth-powder. 
This year, 18,5, 1 found eight of these bones on the sands at Margate, and 
all within a space of a few yards square, The one is seen lying on the 
right of the animal. ; : : 
The upper figure is that of the WEBBED SEPIA, an inhabitant of Green- 
land, and very rare. Its colour is violet. ; 
THE species belonging to the fainily of the Octopodide, or Eight-armed 
Cuttles, possess no external shell likc that of the nautilus, its place 
being taken by two short styles or “pens” in the substance of the mantle. 
There are eight arms, unequal in length, and furnished with double or single 
rows of the suckers which have already been described. 
They are solitary beings, voracious to a degiee, and so active that they 
find little difficulty in capturing their prey or in escaping from the attacks 
of their enemies. Even when pursued into the narrow precincts of a rock- 
pool, the creature isnot easily caught. When threatened, or if apprehensive 
of danger, the Polypus, as the animal was formerly called, darts with arrowy 
swiftness from one side of the pool to the other. :

great aquaria at Brighton and the Crystal Palace, where its extraordinary 
movements and great power of the arms are well shown. 
THE family of the Teuthide, popularly known as Calamaries, or Squids, 
are distinguished by their elongated bodies, their short and broad fins. and 
the horny shell or pen which is found in their interior. All the squids are very 
active, and some species called, FLYING SQUIDS by sailors, and Ommastrephes 
by systematic naturalists, are: able to dash out of the sea and dart to con- 
siderable distances. ~ 
Oor present example of this family is the LITTLE SQuiD, or SEPIOLA, of 
which genus six species are known, inhabiting mosi parts of the world, and 
living on our own shores. 
The celebrated “ink” of these creatures, from which the valuable colour 
called “sepia” was formerly obtained, deserves a brief notice. 
This substance is liquid, and is secreted in a sac popularly termed, from 
its office, the “ink-bag.” The sac is filled with a spongy kind of matter, in 
which the ink lies, and from which it can be forcibly expelled at the will of 
the animal, - The ink-bag is not always in the same position, but some
