(Ernest Edward); Herpetology; Evolution. 246 Advances in Herpetologij and Evolutionary Biology genera diverged from the Anolis stock relatively early (Fig. 1). Chamaeleolis and Chamaelinorops may represent a much earlier invasion of the Greater Antilles than does Anolis itself. If they are relics of an early radiation in which pad morphology, as seen in Anolis, was not fully established, some features of the pad complex, such as setal stalk diameter and the density of setae on the lamellae, may have evolved in parallel in two or three lineages. Differences in pad morphology among Chamaelinorops, Chamaeleolis, and Anolis could reflect alternate pathways in pad evolution. Phenacosaurus is distinct from Anolis, but it may be derived from very early South American anoles (Lazell, 1969; Etheridge, 1960). It could represent yet a third or a fourth lineage in which the pad complex was perfected. The comparisons are designed to determine whether each of the genera can be distinguished from Anolis. In order to minimize the effect of differ- ences in body size or habitat preference on the comparisons, each genus is com- pared with Anolis species which are similar in habitat preference and body size. Ideally the comparisons would also minimize the phylogenetic distance between the Anolis species and the anoline genus, but in practice there are too few data to identify nearest neighbors within Anolis. Chamaeleolis, a large, canopy-dwelling form, is compared with a crown-giant anole ecomorph, A. cuvieri. Cham,aelinorops is a small and.
