II. Diplopoda. 



The Millipedes, Class Diplopoda, are invertebrate animals 

 found in all temperate and tropical regions, herbivorous, slow- 

 moving and incapable of biting a human being, some are nearly 

 10 inches (254 mm.) in length. Head. The head is distinct 

 and has a pair of short antennas (composed of seven or eight 

 segments) in front and two pairs of jaws on its lower surface. 

 Body. The body is more or less elongated and consists of from 

 9 to over 100 segments, all much alike in structure. The 

 majority of species are nearly cylindrical in cross section (but 

 some are flattened), each segment being cased in a horny ring. 

 Legs. The bases of the legs are almost in contact in the middle 

 of the lower surface of the body, there are two pairs to most of 

 the segments, the last pair of legs are never elongated.
