    Trennt man erst einmal nach morphologischen Merkmalen, so muß man sich darüber klar sein, daß die so isolierten Morphotypen unter jedem anderen Gesichtspunkt gesehen immer noch Populationen darstellen können und in den meisten Fällen auch darstellen werden.

    The term morphotype is here introduced for the first time. It is the equivalent of the morphological type or Morphotypus, as used in German. […] it has long been felt among systematic biologists that there are norms (standards) with which actual form-conditions can be compared, in an analogous way as, in the physical sciences, we measure by comparing sizes with standard size units, e.g. the standard meter. In other words, we determnine deviations from an established norm. In morphology, the norm is the morphotype which is an abstraction of the actual form variety within a group of organisms of the same structural plan. It is arrived at by abstraction from the actual form variety within a group (in praxi, usually but no necessarily a systematic category) and thus the actual form conditions can be thought of as being derived from it. Thus, we can arrive at the familiar morphotype of the skeleton of the tetrapod limb disregarding all the numerous peculiarities of form in the inidividual representatives of the group, ancd including only those features thiat are unspecialized and mutually present in all by constructing an extremity consisting proximally of a single, rod-like stylopodium, distally followed by two rod-like elements of the zeugopodium and the latter forming the base of a five-rayed autopodium.
