Increase in aggressive tendency of a female following egg-laying. Interactions were observed between this female and the male captured in the cavity with her, except for July 1 when a strange male was introduced. Hatched bars indicate number of aggressive acts directed toward a male that did not involve a strike ; solid bars indicate strikes. "Open bowl" indicates interactions when the female was removed from her cavity and placed with a male; "female in chamber" indicates interactions when the female was in her "home" cavity, and a male was introduced into the bowl containing the cavity. Brief open bowl encounters were observed on June 9 and 10 when both animals were outside the chamber. On June 12 eggs were laid, and the male left the chamber and was removed to another bowl. parently serves to keep the eggs clean since several isolated masses became con- taminated with what are evidently ciliates (R. Kinzie, University of Hawaii, per- sonal communication ) and some algae. \Yhen defending the cavity, the female leaves the eggs in the recesses of the chamber and comes to the entrance. During this defense she may coil and back into the eggs; this has led to the erroneous statement, originated by Brooks (1886), that the females carry the egg mass over the back (cf. Barnes, 1968). The larvae when they hatch are photonegative and attach themselves to any surface they encounter and thus ar
