Changes in cumulative percentage of females as a function of size during removal. Data for the first three samples combined (open circles) fell into at least four modes (A). Data from the last six samples (closed circles) formed only three discrete modes, displaced upward on the graph due to a later catch of a higher percentage of smaller females (B). The x symbols indicate the relationship for all female size data (N = 2071). The sets of numbers below the lines indicate means, standard deviations, and approximate number (in parentheses) of animals within each mode in Figure 3A, and the numbers above the lines represent the same characteristics for Figure 3B. (See Fig. 2 for separation of modes for the total female data.) samples yielded three modes for the males (Fig. 4B). modes which could be matched quite readily with the three modes representing smaller females in Figures 2 and 3B. On the other hand, data for males obtained in the first three and in the last six samples (Fig. 4) did not show that same parallel relationship found in the female data (Fig. 3). The lines representing the upper mode for males in first and last samples converged. S. R. Haley (personal communication) and M. Page (personal communication) have concluded from laboratory results that males reach a maximum size and cease growth, though they continue molting. Females in the laboratory, according to Haley and Page, showed no such cessation of growth under similar circumstances. The relative percentage of males which fell into each mode also differed markedly in the first and last samples (Fig. 4). The upper (third) mode in the first three samples contained approximately 75% of t
