本文分析了某些六足动物的运动动作和跳跃逃避反应，并描述了它们的辅助形态。所有六足动物步态的共同特征是因为它们只用了三对腿。叠加的特征是四类无翅类和蝶类的特征。这五个纲中每一纲的相关形态是如此独特，而且相互排斥，以至于表明这五个纲中的六足动物是从具有共同头型的多足动物平行进化而来的，与多足动物不同。没有一个六足类可以是任何其他六足类的祖先。跳虫的形态演化与流体静力学跳跃机制有关，这种跳跃机制与深刻的形态特征有关。缨尾蛾腹部的跳跃步态和跳跃反应也与其独特的形态学特征有关。一个分类单元，Uniramia，建议包括Onychophora-Myriapoda-Hexapoda，Uniramia列为几个节肢动物门之一，Onychophora，Myriapoda和Hexapoda形成Uniramia门的三个亚门。结论见第10节，但没有单独的摘要。
An analysis has been made of the locomotory movements and of the jumping escape reactions of certain hexapods, together with a description of their associated facilitating morphology. Common features shown by all hexapod gaits are due simply to the use of only three pairs of legs. Superimposed are features which are characteristic of each of the four apterygote classes and of die Pterygota. The associated morphology in each of these five classes is so distinct, and mutually exclusive, as to indicate a parallel evolution of the hexapodous state in the five classes, from multilegged animals with a common head type, differing from that of the Myriapoda. No one hexapod class could have been ancestral to any other. The morphological evolution of the Collembola has been associated with a hydrostatic jumping mechanism correlated with profound morphological peculiarities. The jumping gaits and the jumping reactions implemented by the abdomen in Thysanura Machilidae are also correlated with unique morphology. A taxon, the Uniramia, is proposed to include the Onychophora-Myriapoda-Hexapoda, the Uniramia ranking as one of the several arthropodan phyla, and the Onychophora, Myriapoda and Hexapoda form three subphyla of the phylum Uniramia. The conclusions are presented in § 10, but there is no separate summary.
