builders, takes quite a different line, having for 
members mussels and snails, cuttle-fish and oy:, 4 
and dividing into two curious groups : the one of 
the shell-fish with heads, and the other of tl 
without any. 
The fifth division, starting also in its own line by

we shall find it full of curious forms showing strange 
habits and ways.

water, and their weapons arc so varied and numei 
that it will be difficult for us even to gain S 
general idea of them. The other three , the 
centipedes, spiders, and six-legged insects, bn
