LIDICKER 1959 20. July 2, recognized lunnus. Picked up 46 traps i grass and set them 37 from canyon. After dinner Stokes, Ward, Dene & myself drove about 1 1/2 mi. down the canyon to beyond it with a scat trap. I set 50 in Opuntia thickets, open areas, & brushy area. After dark caught 3 Bufo around camp & near many more. Caught 2 individuals I wished for Arbacia Elephantasterias. They were calling mainly from cliffs above our water hole but a few had moved down to grade. I got 1 by sitting close to where I was calling & holding a Bufo in my hand which was calling away & apparently stimulated the other to call. The second one called from the edge of the small pond at the base of the cliff. Others got 3 more. Ward shot a Otus trichopsis after dark. July 3 Ran trap lines. Set 50 traps below canyon mouth & had Diplobatrachus verrucani - 1 Pseudacris maculata - 3 (1 discarded) Ranitomeya (pulchra? ) - 1 ap. - 1 Nestorina lepida - 1 (in Mrs. Spec.)
