The skull has a short, broad rostrum and somewhat flat lateral profile, broad interorbital region with parallel, overhanging supraorbital ledges extending posteriorly as ridges onto the parietals (fig. 118). The maxillary cheektoothrows are parallel, slightly bowed posteriorly and separated by a narrow palate with the mesopterygoid fossa penetrating to the level of M2. The teeth (fig. 119A) are nearly laminate, each with three labial flexi extending two thirds across the tooth surface and meeting a short median flexus in the unworn condition. All flexi are notably broad, being wid

. We have added slightly to this database recently, and summarize all available mtDNA cytochromeb data in fig. 120, a strict consensus tree based on 798 base pairs of sequence for 20 haplotypes from the three known species. Available geographic localities are mapped in fig. 117, as are regional monophyletic clades based on the topology presented in fig. 120. Provenance and vouch er specimen catalog numbers are given in table 49. Average Kimura twoparameter distances among regional clades and species are provided in table 50.
