CLASS MYRIAPODA. 



Terrestrial tr ache ate Arthropoda, with a head, followed by a series, 

 usually numerous, of similar somites: with a pair of antennae, mandibles, 

 and maxillae. Limbs 6-7 jointed, ending with a claw. 



The body is elongate, and of nearly the same diameter throughout, 

 and either flattened dorso-ventrally or cylindrical. In the Archipolypoda 

 it appears to have been fusiform. The head is generally somewhat flattened. 

 The numbers of somites in the body varies from five (Eiipaiiropus) to 

 some hundreds in the Gcophilidac (Chilofodd}. In Chilopoda the head is
