Assuming that the sex ratio is 1:1 in both species, these lots are not significantly biased in terms of sex. In order to minimize the effect of ontogenetic changes in morphology on interspecific comparisons, this study used the overall length of the smallest ovigerous female in each sample as a criterion for restricting the analysis to adults. This pro- cedure assumed that overall length, age, and maturity were highly correlated so that the probability of females longer than.
