The retention index is , and the consistency index is The value of the g] statistic is The following nodes in the text were sup- ported by the following bootstrap confidence values (see text for bootstrapping procedure used): Node 1 = ; Node 2 = ; Node 3 = ; Node 4 = Character states are placed at nodes, using MacClade v. (Mad- dison and Maddison 1992), with the characters given in Table 18. The apomorphic state is given in parentheses. Square parentheses indicate equivocal character states that are ambiguous because of missing data or multiple equally parsimonious resolutions. Equivocal characters are placed only at their basal phylogenetic position, and only unambiguous reversals are shown. Node 1, 4(1); Node 2, 5(1), 6(1); Node 3, 7(1); Node 4, 3(1). that family, Lieberman (1998) placed two subfamilies, the Biceratopsinae, comprised of Peachella and Biceratops, and the paraphyletic "Bristoliinae," which included the rest of the aforementioned genera. In Lieberman (1998), "Bristoliinae" contained basically the same genera as in Palmer and Repina (1993) since some of the supra-generic categories had been tentatively defined until all available species within these genera could be considered. This study presents data from all available species for several different olenelloid genera, and is thus an appropriate place to reconsider supra-generic classification within the Ol
