The Myrioiioda, commonly known as Centipedes and Millepedes, form one of the most interesting groups of the whole animal kingdom. In the general structure of the body, which in most of them consists of a considerable number of similar segments, they present a close resemblance to the highest forms of the Vermes, the Annelida, and indeed one type that we must refer to the class {Peripatus) would seem to constitute a complete transition between the two classes; whilst, on the other hand, in the organisation of the mouth, and the presence of only a single pair of true jointed antenna;, we find a transition equally complete towards the time Insecta. Some zoologists have dwelt with perhaps undue force upon the analogy between the Myrio- poda and the larvse of insects with a perfect metamoi-phosis; but too unicli importance can hardly be ascribed to the fact that the youngest I'vse of some of the Myriopods are furnished only. A SCO Id â oS legs. with three pairs of legs, and in other respects much resemble the young of insects with an iiu- perfeet metamorphosis, and above all tlie C'olleni- bolous group of the Thysanura. The Myriopoda may be defined as Arthropods with a distinct liead, and most of the other seg- ments almost precisely similar to one another, with a single pair of antennse, and nearly alwa}'S with simple eyes, with no distinct t
