rock cliff and stayed there for several minutes. We soon heard the flapping again, and saw it in the water and crossing over to the eastern side of the upper shelf. We captured it when it again climbed up on a rock cliff and could only identify it as a Mystic sp. We then put it on a rock at the so. end of the hole and left it to dry. Only a few minutes later, it tried to fly, was still too wet to do so successfully, and so ended up back in the water again. This is evidently the way that these bats end up drowning in the water - continuously trying to fly too soon and ending up back in the water. Bees also in water. Algae was dispersed considerably because of setting and placement of the cage. Planaria were again observed on a beetle. Planarians were not very active until dark. I Collected an unidentified larva? and some beetle. Some fish were preserved in formalin. Light needed to complete observations. Very dark at 8:15 P.M. when we left. Noted - one fish (5-7mm) was attracted by the flashlight as I collected the beetle. I used my finger to brush it away, actually touching it several times, but it would not leave, staying at the surface at the rocks used to stand on (so.end). Water temp - 33.5°C. Water level (2000hrs) - 1.94 on scale. * Cage - a cage was constructed and placed in Devil's Hole at this time. Composed of a frame- cage of 1/2" wire mesh hardware cloth
