Duellman 1 and Rebecca A. Pyles 2 In a review of the marsupial frogs (Gastrotheca) of the Ecua-dorian Andes, Duellman (1974) noted the occurrence of uniform green frogs on the Amazonian slopes of the Andes. Subsequent field work resulted in the acquisition of series of these green frogs, which are similar to G. plumbea (Boulenger) on the Pacific slopes of Ecuador and to G. mertensi Cochran and Goin from the eastern slopes of the Cordillera Central in southern Colombia. The latter species produces tadpoles (Cochran and Goin, 1970), whereas G. plumbea and the frogs on the Amazonian slopes have direct de-velopment of eggs into froglets. No other populations of Andean Gastrotheca are composed of uniform green individuals, although occasional green specimens of G. marsupiata ( Dumeril and Bibron) and G. monticola Barbour and Noble lack dorsal markings (Duell-man and Fritts, 1972; Duellman, 1974). Thus, we undertook an analysis of the Andean populations of green Gastrotheca in an at-tempt to determine their systematic status. ANALYSES OF POPULATIONS For purposes of analysis the frogs were assigned to three geo-graphic populations — Amazonian, Pacific, and Colombian. Sixteen morphological measurements were obtained from each specimen. 1 Curator, Division of Herpetology, Museum of Natural History; Professor, Department of Systematics and Ecology, The University of Kansas, Lawrence, Kansas 66045. -Research Assistant, Division of Herpetology, Museum of Natural History, The University of Kansas, Lawrence, Kansas 66045.
