[93]. At the same date (March, 1869) we independently suggested that the insects had originated from some form like the hexapodous young of Pauropus and Podura. In November, 1870, we suggested that the Thysanura and the hexapodous Leptus may have descended from some Peripatus-like worm. Afterwards (1871) we proposed for the ancestral form the term leptiform, which was later abandoned for Brauer’s term Campodea-form.
