According to Rieppel (1984c) the postfrontal acts as a lateral brace for the otherwise highly kinetic frontoparietal joint. An elongate, blunt-ended process projects ventrolaterally to form the posterodorsal border of the orbit. The shape of the postfrontal is general for car- phodactylines but also occurs in several other gekkonid lineages (Häupl 1980). In Uroplatiis fimbriatus the lateral prong of the element is extremely elongate and, as in some carphodactyhnes, it is connected to the mandible by a calcified postorbital liga- ment. In most species the element changes shape ontogenetically. Initially the limbs of the post frontal are narrow and the bone as a whole is "y'-shaped. With age the limbs thicken and broaden and the element becomes more "v'-shaped. Primitively in the Car- phodactylini the lateral limb of the postfrontal curves somewhat downward as it does in many of the members of the outgroups. In Rhacodactylus auricidatus and R. leachianus, however, the process is so downcurved as to be oriented nearly vertically (Fig. 7) (character 6). Character 7: Posterior border of parietals distinctly emarginate (0), or complete — roofing entire occipital region (1). Character 8: Parietals as a unit approximately as long as wide (0), or short and very wide (1). Character 9: Frontoparietal suture straight (A), or curved (B). Character 10: Parietal crest at mid-dorsal suture absent (0), or present (1). The parietals are the posteriormost roofing bones of the skull. The paired condition shared by all diplodaclylines has been considered both primitive (Moffat 1973a) and derived (Kluge 1967a) for gekkonids, although there seems little support from outgroup comparison for the former view. Stephenson (1960) reported partial fusion of the parietals in Carphodact
