ABSTRACT. Relationships of the Puerto Rican anoles were investigated through both phenetic and cladistic treatments of two independently generated multi-locus allozyme data sets. These findings are compared with a phylogeny developed from previously reported karyotypic data. Phylogenetic treatment of the data supports a rather conventional view of the relationships of the Puerto Rican anoline radiation. There is electrophoretic support for the recognition of three major karyotypically limited lineages: 1) Anolis evermanni and A. stratulus; 2) A. cooki and A. cristatellus; and 3) A. gundlachi, A. poncensis, A. pulchellus, and A. krugi, although A. gundlachi clusters with the latter group based on a karyotypic rather than any electrophoretic character. Within the third lineage, A. poncensis is the sister-taxon of a group comprised of A. krugi and A. pulchellus, and these three "grassbush" anoles are in a sister group relationship to A. gundlachi.
