. Bonner zoologische Monographien. Zoology. 67. C. percarinatus Fig. 26: Posterior view of skull of Corytophanespercarinatus. Dorsal expansion of bony labyrinth and limiting angles of parietal result in the closure of the postemporal fossa. Notice the broad con- tact of quadrate process of pterygoid with quadrate. ma, all iguanines except Dipsosaurus and in tropidurines exclusive of Uranoscodon and Leiocephalus. The distribution of the character states at the outgroup nodes shows a (2:1:1) consensus distribution. No unequivocal polarity decision at the ingroup/outgroup basal node can be made.

The distribution of the character states at the outgroup nodes shows a (2:1:1) consensus distribution. No unequivocal polarity decision at the ingroup/outgroup basal node can be made. Within the ingroup, Basiliscus invariably shows the presumed intermediate condition (fide Etheridge & de Queiroz 1988). In Corytophanes and Laemanctus the bony laby- rinth is elevated well above the occipital bones (presumed apomorphic condition)..
