Quart 1948 Dauphne ega 1 May 18 Trunfo, 1700 ft, Baja California One shot by Dr. Benson last night at 7:00 P.M. Specimen was flying near roadway and near mesquite trees. Specimen prepared and cataloged by Dr. Benson. One shot by Murray near Mesquite trees in canyon bottom at about 7:15 this evening May 25 El Carrigalito, 1400 ft, 5 mi N Santiago, Baja Calif One shot by Murray last night at dusk as it was flying over a cornfield nearby our camp. May 27 Same Location One shot by Dr. Benson as it was gliding down the hillside toward the flat below at dusk yesterday. May 29 Same Location One netted by Dr. Benson at 8:30 last night as it was flying over pond near caretaker's house (see map pg. 91 of journal). May 30 El Choro, 800+ ft, 3 mi W Agua Caliente, Cape District, Baja Calif Shot two yesterday at dusk over irrigation dam at this place (#272, 273). Both were females and had two embryos apiece. These were flying much lower than the Tadarida femorosacca obtained at the same time. It is believed that one of this species hit wires strung over pond just above dam at 9:30 P.M. I turned the light on it and it swam to the opposite side and was lost in the reeds. They appear to be good swimmers.
