Abstract: 1. The size distributions of gravid females in the intertidal region for the two species are almost identical, but P. granosimanus carries about twice as many eggs as P. samuelis. 2. For an animal of a given size, there is a large variation in the number of eggs carried. 3. Gravid P. granosimanus smaller than any in the intertidal region are found in the subtidal region. 4. P. granosimanus eggs increase more rapidly in weight than do P. samuelis eggs. 5. P. samuelis increase slightly more rapidly in size, because they become more elongated.
