Field observations on each of these species are presented. Morphological traits (mean adult size and sexual dimorphism, weight, size and color of dewlap, relative lengths of tails and limbs) and behavioral and ecological traits (temperature preferenda, height and diameter of perch, season of egg-laying, display-activity patterns) are listed and discussed. In the past, several of the species have been considered subspecies of other species. In each instance status is discussed and evidence for full specific status is presented. Lack of close ecological counterparts between Mexico, Central America and Ecuador is demon-strated. The Ecuadorian series of species tends to arboreal habits, large size, and rela-tively long tails. The Mexican species tend to terrestrial habits, small size, and marked sexual dimorphism, with males usually larger than females. * Division of Biological Sciences, University of ** Department of Biology, Baylor University, Kansas, Lawrence, Kansas.
