The rock lizard Agama atra atra from Namaqualand differs in both body size and reproduction from other populations of this species occurring elsewhere in southern Africa. Both sexes from Namaqualand are significantly larger than their counterparts in the south-western Cape. While reproduction in this species is stiongly seasonal elsewhere, it is apparently continuous in Namaqualand. Females with vitellogenic ovarian foll icle6 and/or oviducal eggs were collected during the winter monlhs, a time when females are typically reproductively quiescent in other populatlons. Aseasonal reproduction and large body size ol this species in Nimaqualani do not correlate with prevail ing environmental condil ions in the area. The presence ol at least one other species with continuous reproduction and two others with tropical aif init ies in the same general area, suggests that the Namaqualand population of A. a. atra may be a tropical relict. Die bloukopkoggelmander,Agama atra atra, wat in Namakwaland voorkom, verskil in beide l iggaamsgrootte en voortplanting van ander populasies van hierdie spesie wat elders in suidelike Af rika aangetref word. Beide geslagte van die Namakwaiandse vorm is aansienlik groter as hul eweknieii elders. Voortplanting by hierdie ipesie is elders uitgesproke seisoenaal, maar in Namakwaland is dit oiinskynlik aaneenlopend. Wylies me
