The West Indian assemblage of xenodontine (Colubridae) snakes was phylogenetically evaluated with allozyme data and restriction site data of the ribosomal DNA repeat. To assess mainland relationships, 24 xenodontine taxa from Central, South and North America were included with the 18 Antillean taxa. A natricine, Nerodia fasciata, was included and employed as the outgroup in the initial analyses. Outgroup substitution was used to determine proper outgroups and evaluate hypotheses of monophyly. Allozyme data were collected for all taxa and resulted in 20 informative characters. The ribosomal DNA data were collected for 16 taxa and proved uninformative at a higher taxonomic level. Cladistic analysis revealed four separate lineages in the West ...
