Hendrickson 1950 "Kyla microcephala" Nov. 9 Villavieja, 1400 ft., Kaila, Colombia, S.A. Found numerous individuals in an area of pools on low ground W of the cemetery. See map in today's journal for details of locality. See Dr. Stibbins notes for results of our study of voice, etc. The frogs collected were all perched on blades or stones of tall grass (to 15" above water level) growing in pools of water, or on other plants growing out of the water. None were found on similar plants at the pond edge which were not submerged at their basal portions. One I saw with vocal pouch extended (partially so?) gave me the impression of suffused dark pigment on the pouch. The general color of the living frog was a pinkish tan, fairly rich in hue (this by light of my headlamp).
