CLASS MYRIAPODA. 



The best known animals of this small class are the Scolopendrce, 

 or Centipedes. Their body is formed of a great number of rings, 



Scolopendra. 



which are all alike, except the first and last. Each of these rings 

 is furnished with a pair of legs, and the animal advances with the 

 aid of all its legs, which are sometimes a hundred or even more 

 in number. Our small native centipedes live under stones, and are 

 almost innocuous ; but the large centipedes of hot countries 

 inflict very painful and dangerous wounds with two hooks placed 

 on each side of their head.
