Within this phylogeny, C. mccordi appears to be most closely related to C pritchardi (Fig. 10), sharing the derived features of lack of chelid foramina and partially narrowed parietal roof, as well as the plesiomorphic features of a shallow skull, decreased robusticity, narrow triturating surfaces, and par- allel pterygoid processes. The two species C. reimanni and C. novaeguineae share the derived features of a narrow parietal crest, flaring pterygoid processes, wide triturating surfaces, deep skulls, increased robusticity, and loss of chelid foramina. In view of the isolated occurrence of Chelodina mccordi on the very small island of Roti, where available habitat may be limited, and human utilization pressures are perhaps heavy, an investi- gation into the population and survival status of the species needs to be undertaken. Basic ecological and life history data on the species are also extremely limited and further investigation is needed. Finally, the application of modem methods of molecular.
