The force generated by the primary dactyl was about 8- and 3-fold greater than that generated by extra dactyls a and b, respectively (Fig. 8). The primary dactyl moved spontaneously and asynchronously with the extra dactyls just before the electrical stimuli were applied to the nerve bundles (Fig. 8A. A').

Discussion There have been previous reports of double extra claws developing from the carpus (Bateson, 1894) and coxa (Przibram, 1921) of the crayfish (Astacns fluvkitilis) and from the propodus of the cheliped of lobster (Homarus americanux) (Cole, 1910). Recently, two extra claws that. Figure 5. Innervation and muscles in the propodus of a cheliped with two induced extra claws. The cheliped is the same as that shown in Figure 2C.
