Murray 1948 79 Journal May 23 Buena Vista, 25°F., 23°38′N, 109°41′W, Baja Calif Shot 1♀. Callisaurus draconoides is thick here and exceedingly tame. Also saw some Diposaurus dorsalis, and Uta microscutatus late in the evening. Shot 2♀ Eptesicus fuscus in the evening. The bats flying here seem to follow a pattern, with the Myotis flying at early dusk, feeding over the brush beside the road where I stand. Later, when it is much darker, the Eptesicus, and whatever other large bats there are come straight and fast down the road, so consistently that it must amount to a pathway. May 24 Same location to Las Cuevas On our way again, driving the short distance to Las Cuevas. Here found a crude town of thatched huts overlooking a broad river bed with high, sheer, solid sandstone cliffs. On the far side we found a large cave washed out of the base of the cliff, with aid of 19 Mexicans. This had two main chambers at tandem, the first about 30 ft. high, and the other more than 20. Total depth was around 120 ft. At the rear and high on the wall was a solid mass of Myotis
