Quart 1948 Mystis californicus 3 June 22 Santa Rosalillo, 25+ ft, 5F and Bahia de Concepcion, Baja Calif. I finally obtained the specimen by letting it crawl onto the end of my net which I dipped into the water. On examining the specimen I could find no gunshot wounds, only a slight reddish area on the right forearm. June 25 Los Martires, 300+ ft, 23 mi by road NW San Ignacio, Baja Calif. One male, #434, shot this evening at dusk as it was flying over low brush 100 yards north of the coral. A very strong wind was blowing and the bat appeared to have difficulty in navigating. It has been noticed before and was noticed to - night that this species appears to feed over a wide area and is usually glimpsed only as it is flying by. It seems not to feed in the small areas noticed in Epterus fuscus and Pipistillus hesperus, several small bats possibly of this species were glimpsed drinking at the long watering trough at this place but they were not obtained due to the wind. The boy at the ranch said that many bats visited the tanks on quiet nights. This bat was feeding singly, no other bats being near at the time it was shot. June 26 Arroyo San Louis, 800+ ft, 9 mi W Calmelli, Baja California One J #41, obtained in the mine at this place this afternoon (see Journal pg. 138 for description of mine). Two others were seen in the upper stope section
