CommentThe only Cryptoblepharus with interparietal distinct from the large, single frontoparietal shield. Cogger et al (1983) noted “common in household gardens and road- side vegetation between Flying Fish Cove and Rocky Point; basks on stone or brick walls, fences, ornamental trees, shrubs and coconut palms; also seen on fallen tree trunks as- sociated with clearings in primary rainforest; iridescent blue tail is a feature of both sexes and is brightest in juveniles, the intensity of colour diminishing in large adults”.

Conservation: Extinct in the wild fide Tingley et al. 2019. 
EtymologyNamed after HMS Egeria, which visited Christmas Island (1887).
