Note that both scales are logarithmic. calculated for these paired variables (Table I). Capsule length accounts for 55% of the variations in egg counts (r-, ). However, capsule size accounts for only 25% to 28% of the variations in embryo counts. Several capsules were deposited in the laboratory, and these contained more embryos (; , ; N, 16) than capsules from the field (Fig. 1). The late embryos in these capsules were also significantly smaller (mean shell length, mm; , ; N, 14 embryos) than those found in capsules from Tomales Bay (mean, mm; , ; N, 24; Fif3o = , P < )..
