J. Rodgers - 1942 Ernecea skiltoniana Sept. 18, 4:00pm (cont.) Mus. Vert. Zool., Univ. Calif., Berkeley, Calif. Eggs I in nest no. III was very wet and covered with dirt. I took it on't washed it off. I have suspected before that the moisture that seems to persist on these eggs (see last day of nest no. 1) comes from within them. That is the only way this one (no I) could have gotten that much wetter than the others.

Egg no III was found buried in dirt that had been thrown out of the nest. Egg no I has shrunk apparently to the size of the embryo inside. Nos. IV, V, and VI were wet. No water has been added to put into this cage for the past two week, and the soil around the eggs is barely moist. The moisture must have come from the egg or the skin. Only egg no II appears normal now. Temp inside nest no 3, 9:30am 17.5°; outside, 19° " " " 36.5°, " 28° 1:30 am. All the eggs were opened and the embryos examined. Embryo no 3 was least developed, no I next and the others were all about the same. No II may have
