The incubation time of Eumeces chinensis eggs at 30±0.3°C averaged 22.6 days. During incubation, the pliable-shelled eggs of E. chinensis increased in wet mass. Dried shells from freshly laid eggs averaged 4.1% of the entire egg dry mass. No significant difference in shell dry mass was found between freshly laid and hatched eggs with the same wet mass at oviposition. During incubation, approximately 66% of dry mass, 44% of non-polar lipids and 62% of energy in egg contents of the freshly laid egg were transferred to the hatchling, with 34% of dry mass, 56% of non-polar lipids and 38% of energy used for embryogenesis. Fully developed embryos could obtain all magnesium from yolk but withdrew approximately 19% of their total calcium requirements from sources other than yolk.
