Abstract
Nine meristic and fourteen morphometric characters were examined to determine geographic variation in the five subspecies of the insular snake species, Alsophis vudii. In addition, museum specimens from the closely derived species Alsophis cantherigerus were examined. Canonical discriminate analysis determined that, based on the morphological data, significant differences were observed among subspecies. However, significant differences were also observed between island populations. My results suggest that the current subspecies designations oversimplify the variation within the species and are not an adequate reflection of variation present among the island populations. Additional research is required in order to determine the causes of the observed variation within the species. Possible explanations for observed variation may include multiple colonization events or environmental variation among islands.
