SUPPLEMENT 



ORDER MYRIAPODA 



The characters of this order have been amply detailed in 

 the text, and our supplementary notice of it must be slight 

 indeed. There is little of any interest to be found, at least 

 in a popular point of view, in the insects which compose it. 



The myriapods live and grow for a longer time than the 

 other animals of this class, as has been mentioned in the text. 

 They can scarcely be considered as undergoing metamor- 

 phosis, unless we regard the development of additional feet 

 and rings, in proportion to age, as such. This is what M. 

 Latreille calls " ehauchee,"" or a mere imperfect sketch of 

 transformation. The myriapods may thus be considered as 

 forming a passage from the insects to the Crustacea. In ex- 

 ternal forms they approximate to the latter, but their inter- 

 nal organization, the only proper basis of methodical divi- 

 sions, associates them to the former. It is just thus that the 

 trachean arachnida resemble in exterior the pulmonary 

 arachnida, but are nevertheless closer to the insects in all the 

 relations of internal structure.
