June 24, 1951. Nest occupied by a gravid female, apparently ready to lay. June 30, 1951. Rock covering this nest has been undermined by a mole tunnel, and many nearby rocks are undermined also. The eggs were almost certainly destroyed by the mole's tunneling and may have been eaten by it, since no remains are in evidence. No. 5. At hilltop ledge beside old abandoned road, beneath flat rock nine inches in diameter and about 1-1/2 inches thick, shaded for first half of morning and most of afternoon, but exposed to mid-day sunshine. June 29, 1951. Standing water in bottom of nest chamber 1-1/2 inches below underside of the rock. Some of the eggs are more than half submerged. One egg is 14 × 8 mm. July 21, 1951. Entrance of abandoned nest burrow has been enlarged by running water channelled through in run-off during and after heavy rains; shrivelled remains of eggs present at the bottom of the burrow. No. 6. On grassy hilltop a few yards from ledge under flat rock, 9 × 6 × 2 inches. July 23, 1951. Large female (snout-vent length 75 mm.) with three eggs, 16 × 22 mm. July 27, 1951. Female escaped from nest cavity as rock was raised. Three eggs were still in the nest, and a young skink was partly emerged from one. A second egg not yet hatching was somewhat flaccid, 16 mm. long, heavily coated with dried mud. The third egg much shrivelled, was opened and found to have a dead fetus, perhaps a week short of hatching. July 28, 1951. The flat rock which formerly covered the nest cavity was found to have been raised and displaced, and no trace of the female, eggs or young remained. Of possible predators that might have moved the rock and destroyed the nest, skunk and opossum seemed the most likely, but there was no definite clue as to the predator's identity. No. 7. Two feet northeast of pond rock pile, under rock about one foot square on upper surface with maximum thickness of about eight inches, lying with upper side at 45-degree angle. The nest was under one edge, with approximately three inches of rock over it. The rock was exposed to sunshine throughout the day, except for grass shading its edges. July 23, 1951. When rock was turned, the female darted out of the nest cavity, but in her dash to escape she dropped into a nearby pitfall. When handled, she voided feces which contained the nearly intact shell of a skink egg. Six eggs present in the nest; one selected as typical was 11-1/2 × 8 mm. The eggs were slightly misshapen and might have been damaged from drying. July 26, 1951. When rock was raised, female darted out and escaped. The six eggs still remained in the nest.
