Eleuthodiscus ovalis Nov. 6 5am. N. Villavicencio, 1400 ft., Huila, Colombia, S.A. Dr. Stebbins and I found one in semi- matted grass in puddle in banana patch S. of camp. We heard its almost icada-like call about 75-90 yds. distant, triangulated it and studied the call from about 10-15 ft. (see Dr. Stebbins notes, his # 5021, for analysis of call). We then located the frog on the third attempt (retreating and waiting for it to resume its calling after failing to collect it_ on the first two attempts. It was collected at about 7:35 P.M. It moved, apparently about 2 ft. as a result of our unsuccessful first attempts to collect it. It was beneath about 6" of semi- matted grass, sitting on grass stone in 1/4"- 1/2" water (of a puddle 1"-3" deep). I would syllabify its call as: "beeeeee ....... beeeeee ......." (the "b" being a soft, "Spanish" "b"). (see Dr. Stebbins notes for tempo, etc.) The immediate area where the frog was found is in the low corner of the banana patch. The
