Lynch ^^i^ggARiE^ Museum of Natural History, University of Kansas, Lawrence; present address: Department of Zoology, University of Nebraska, Lincoln The discovery of petroleum deposits in Napo Province, Ecuador has proven to be of considerable importance in the herpetological exploration of the Amazonian rainforest in eastern Ecuador. Recently, Texaco Petroleum Company has undertaken the construction of a new airfield near its Lago Agrio oil field. The University of Kansas Museum of Natural History personnel have been fortunate to gain early entrance into this newly-opened area. During April and May, 1969, a group of three herpetologists collected and observed am-phibians and reptiles at Lago Agrio while the Texaco crews were leveling primary rainforest for the new airstrip. A sig-nificant number of animals which had only rarely been col-lected in the past became relatively abundant, presumably because these species are dwellers of higher levels of the rain-forest than are usually sampled by the terrestrial collector. Among the leptodactylid frogs collected amid the bulldozers were two specimens of a distinctive new species of Eleu-therodactylus. Fortuitously, both an adult male and an adult female were collected. Roth sexes of this species have dark brown and black gular regions; in allusion to the throat color, this new species is named Eleutherodactylus orphnolaimus new species Holotype: University of Kansas 125332, adult male collected at Lago Agrio, Napo, Ecuador, 330 m, on 7 May 1969 by Thomas H. Fritts. Paratype: KU 125333, adult female, same locality, collected 9 May 1969 by William E. Duellman. 21— Proc. Biol. Soc. Wash., Vol. 83, 1970 (221)
