摘要

本研究描述臺灣麗紋石龍子雌雄異型及其生活史。成蜥的體色、體型和頭部大小皆呈雌雄異型。雄蜥的吻肛長、頭長、頭寬、頭高和第三趾長皆比雌蜥大。麗紋石龍子於三月開始活動，八至九月達到高峰；十二月至隔年二月冬眠。幼蜥的平均生長速度比成蜥快。

Sexual size dimorphism in the five-striped blue-tailed skink, Eumeces elegans, is presented. Adults are sexually dimorphic in coloration, body size, and in head sizes. Males attain a larger size than females in snout vent length (SVL), head length (HL), head width (HW), head depth (HD), and 3rd toe length (TTL). Annual activity begins in March, peaks in August-September; lizards are inactive from December to February. Mean growth rates in SVL of juveniles were greater than those of adults.
