In the case of the female abdomen/carapace allometry, the difference between molting and non-molting stages was apparent upon constructing a scattergram (Figure 1) and they could be collected into immature-prepubescent and mature stages for the computation of allometric constants. A preliminary computation based on size classes (shown in the figure) gave some hint of the prepubescent stage, but this was neither distinguishable in individual crabs nor statistically valid for the purposes of computing constants. The males presented a more difficult case, although the immature and prepubescent sizes were rapidly distinguishable in the scattergram, much of their size ranges intergraded imperceptibly. How- ever, the smallest prepubescent and the largest mature sizes were evident beyond the intergrading region, and the very smallest mature sizes were identified by their mature gonads and also by their having three layers of barnacles, an indica-.
