Note 4 — PART I.—MORPHOLOGY AND PHYSIOLOGY
Reading edition
The term which we proposed for this hypothetical ancestor of insects, “Leptus-like” or “Leptiform,” was an unfortunate one, since the name Leptus was originally given to the six-legged larva of a mite (Trombidium), the origin of the mites and other Arachnida being entirely different from that of the myriopods and insects.
