THE MYBIAPODA. In these Arthropods, the body is di- 

 vided into many segments, the most anterior of which takes 

 on the characters of a distinct head ; and almost all these 

 segments bear articulated limbs terminated by claws. In 

 the Centipedes ( Chilopoda), the segments of the body have 

 broad sterna, and the bases of the limbs are far apart ; but, 

 in the Millipedes (Chilognathd), the sternal region is rudi- 

 mentary, and the bases of the limbs are close together. 



Pro. 95. A. Scdopendra borbonica (Chilopoda). B. lulus flavozonatus (Chtio- 



gnatha). 1 



Moreover, in the latter group, the majority of the segments 

 of the body bear two pairs of limbs, and probably represent 

 two somites.
