Note 65 — Chapter V
Reading edition
A still nearer approach is afforded by the genus Peripatus, which since the above was written has been carefully described, especially by Moseley and Hutton. There are several species, scattered over the southern hemisphere. In general appearance they look like a link between a caterpillar and a centipede. They have a pair of antennæ, two pairs of jaws, and (according to the species) from fourteen to thirty-three pairs of legs. They breathe by means of tracheæ, which open diffusely all over the body.
