Pcrijxiivg Edward- sii Blanch., P. cajjeni^is Gr. Class IV.âMYRIAPODA.* Tracheata with separated head and numerous fairly similar seg- ments. They have one ^yair of an- tennce, three pairs of jaivs, and numerous pairs of legs. The M}i-iapoda of all the Arthro- j)oda present the greatest resem- blance to the Annelids, in the serial similarity of the segments, in the possession of an elongated, some- times cylindrical, sometimes flat- tened body, and in the mode of locomotion. In fact, they bear njuch the same relation to the An- nelids that the Snakes do to the vermifonn fishes amongst the Vertebi-ata, * J. F.
