Figure 1. Hypotheses of phylogenetic relationships of West Indian xenodontines from Maglio (1970). a.) Relationships among taxa in the funereum assemblage. Specific epithets are all Arrhyton. b.) Relationships among taxa in the cantherigerus species assemblage. Specific epithets are all Alsophis. Maglio's (1970) melanotus and andreae species assemblages are not shown because Liophis was not included in this study and because the andreae assemblage contains only two species, the latter and Antillophis parvifrons.
