Murray 1948 60 Journal May 11 24.3 mi SE El Refugio, 100±ft., 24°10'33"N, 111°0'35"W, Baja Calif. El Refugio. We are located in a circular bare area surrounded by the same dry vegetation -- cholla and pitahaya agria mostly, with cardona, ocotillo, matacora and pitahaya dulce. It is flat as far as the eye can see. Set my 50 live traps, spaced 60-70 feet apart in the cactus which is fairly dense. There are a few kangaroo rat burrows apparent. Saw two large bats flying at dusk. Can't imagine where they would live or get water around here without traveling a great distance. It was a little hotter today than recently, yet not extreme. May 12 Santa Ana, Arroyo de los Viejos, 25±ft., 24°03'N, 110°58"W, Baja Calif. Caught 3♂, 1♀ Dipodomys merriami, 1♂, 1♀ Dipodomys agilis in the traps. Also taken here were Perognathus arenarius and Perognathus baileyi. Something chewed and opened one of my traps. This morning we woke up to a rather heavy fog and dew on everything. The minimum temperature was 53°. Traveled today over poorer road,
