412 TRANSFORMATIONS OF INSECTS. 
and it would appear, according to Savigny, that they correspond * 
with the three thoracic legs of insects which have very different 
functions, however. 
The Myriapoda are divided into two great orders, which can be 
distinguished very readily. The “Thousand Legs,” which have 
two pairs of legs to each segment of the body, and antenne with 
seven joints, constitute the first order, or that of the Chzlognatha ; 
and the “ Hundred Legs,” which have one pair of legs to each 
segment, and also long tapering antennz, with fourteen or more 
joints, form the second order, or that of the Chzlopoda. 
The Chilognatha are fond of hiding up under stones, in damp, 
dark places, and they live upon decaying vegetable matter and

the tender rootlets and buds of plants. They have not very 
formidable jaws, and the common genus, ¥u/ws, which is to be 
found everywhere in gardens and fields when the upper soil 
is disturbed, may be considered the type. The Fulzde@ have not 
really a thousand legs, but several hundred pairs may exist upon 
the long and cylindrical body, whose twistings and serpentine 
motions impress observers very unfavourably concerning the habits 
and intentions of the creature. 
The Chilopoda, on the contrary, are insects of prey, and chase 
and kill all sorts of small living things, upon which they feed with 
their strong jaws. The Scolopendra is the type of this division, 
and is a very formidable hunter. Its head appears to consist of 
two parts—one a circular shield-like plate, into which are fixed the 
antenne and the eyes, and the other a large and strong segment,
