Herpetological Review 50(1), 2019 NATURAL HISTORY NOTES 141 which were captured by hand in the rocky outcrop. These eggs were obtained after we euthanized the animals. On 1 December 2016 (80 days after collection), a juvenile emerged from the field-collected egg; its measurements were: SVL = 23.0 mm; TL = 25.1 mm; body width = 3.2 mm; body height = 2.4 mm; head width = 4.4 mm; head length = 7.4 mm; head height = 2.7 mm; forearm length = 9.0 mm; and hind limb length = 12.2 mm. Dorsal coloration was dark brown, with black rings and white spots along the medial region from head to snout, while the tail region showed alternating white and black rings (Fig. 1). Ventral coloration was light yellow. The eggs from pregnant females ranged in length from 4.5–7.9 mm and width from 4.1– 10.1 mm. By using the formula of volume for an ellipsoid, the eggs showed a mean volume of 63.27 ± 49.5 mm 3 (range = 20.06 – 185.17 mm 3 ; N = 16). Clutch size was invariably two eggs per female, matching most gekkonids and phyllodactylids (e.g., Colli et al. 2003. J. Herpetol. 37:694–706). The hatchling G. darwinii (4845) and its eggshell were deposited in the Herpetology Section, Coleção Herpetológica e Paleoherpetológica da UFRPE, Recife, Pernambuco state. To the best of our knowledge, this is the first record of egg sizes, hatchling sizes and incubation period of G. darwinii.

INTELLIGAMA LESUEURII (Australian Water Dragon); ACRITOSCINCUS DUPERREYI (Three-lined Skink); LAMPROPHOLIS GUICHENOTI (Garden Skink). INTERSPECIFIC COMMUNAL NESTING. Communal nesting is common and widespread in lizards, but their often secretive nesting habits prevent us from understanding its taxonomic distribution, hindering our ability to explain its evolution (Doody et al. 2009. Quart. Rev. Biol. 84:229–252). Field observations remain critical in this regard. Herein I report a mixed-species communal nest of three lizard species. On 15 December 2007, while conducting surveys for Intelligama lesueurii nests at Blue Water Holes, along Clark Creek in Kosciusko National Park in southeastern Australia (35.62262°S, 148.70427°E, WGS 84; 1153 m elev.), I discovered a nest of I. lesueurii in a narrow (ca. 8 cm) crevice in bedrock on an open, north-facing sloping cliff face. The nest was buried under shallow soil (ca. 6 cm), but small amounts of soil on the surrounding rock from the excavating mother served as a clue. While removing and measuring the seven I. lesueurii eggs, I discovered two sets of smaller eggs in the nest. There were eight eggs in a single cluster and four smaller eggs in another (looser) cluster; both clusters were among the water dragon eggs, the latter of which were buried in roughly three layers in the soil. Two eggs from each cluster were brought to the laboratory (University of Canberra) and incubated at a constant temperature of 30°C in Thermoline® incubators. Hatching of all eggs occurred within two weeks; the larger eggs were confirmed to be Acritoscincus duperreyi and the smaller eggs Lampropholis guichenoti. The three clutches of eggs were within the range reported for each species in the literature, suggesting one clutch per species (Pengilley 1972. Systematic relationships and ecology of some lygosomine lizards from southeastern Australia. Ph.D. Thesis, Australian National University, Canberra, Australia; Greer 1982. Rec. Austr. Mus. 64:549–573; Doody et al. 2006. Evol. Ecol. 20:307–330). Communal nesting has been reported in all three species (reviewed in Doody et al., op. cit.), but mixed-species communal nesting has been reported in only L. guichenoti (Shea and Sadlier 2000. Herpetofauna 30:46–47). Mixed-species communal lizard nests are rarely reported (Shea and Sadlier, op. cit.), but may be more common than realized. If incubation requirements are similar among species, then we might expect mothers to add their eggs to those of other species, if they find them. In theory, mothers can save time and energy and decrease their vulnerability to predators by nesting communally if they find nests early in their search for a nest site vs. spending more time searching for their own nest site (Doody et al., op. cit.). Alternatively, in the present case soil for nesting was limited to a few crevices in limestone bedrock; mothers may have had few choices of where to lay their eggs. I suspect that the loosening of the soil by the nesting water dragon mother provided an easy pathway into the soil for the other skink mothers, but I was unable to confirm that the water dragon eggs were deposited first. Importantly, these two scenarios—conspecific copying vs. limited nest sites—are not mutually exclusive, and persistent limited nest sites over many generations at the site may have selected for mothers recognizing and adding their eggs to those of conspecifics or other species, given the similar incubation requirements among species (Doody et al., op. cit.).
