SYSTEM OF INSECTS. 



by Gonyleptes ; or, according to Mr. MacLeay 9 the 

 transit is to both by Galeodes*. But as there is reason 

 for thinking that this last belongs to the Pulmonary 

 Arachnida b , and forms a peculiar type in that Class, I 

 consider the transit from the one to the other as above 

 stated. The folded abdomen of Gonyleptes seems much 

 to correspond with that of the cancriform spiders (Car- 

 kinodes cancriformis, &c.). 



DEF. Metamorphosis complete. 



Body consisting of one or two principal seg- 

 ments. 



Mouth various . 



Antennas obsolete, or represented by mandibles. 

 Legs mostly eight, but in a few six only d . 



Polypods. This suborder consists of Dr. Leach's 

 Class Myriapoda, or the Chilognatha and Chilopoda of 

 Latreille, corresponding with the Linnean genera lulus 

 and Scolopendra. Mr. MacLeay has arranged them in 

 the same Class with the Hexapods, and connects them 

 with the Anoplura by means of certain intestinal worms 

 of an indistinct annulose structure 6 (Entozoa Nematoidea 

 Hud.), in which the sexes are dioecious, and some of 

 which are furnished with lateral spinulae, thus, as he 

 supposes, connected with the Polypods ; and with the 

 Anoplura by others (Epizoaria Lam.) in which appen- 

 dages appear somewhat analogous to the legs of Hexa- 

 pods, as in Cecrops Leach, and which like them are 

 parasitic animals f . But the right of these worms to be
