May 28 Same Location One caught by caretaker here last night as it flew over pond by this house. One also netted by Murray. May 29 Same Location One netted yesterday at 8:00 P.M. as it was flying over pond at caretaker's house (# 270) June 22 Santa Rosalillo, 25+ ft S.E. end Bahia de Concepcion, Baja California One male #434 obtained at the water hole this evening at about 11:00 P.M. This specimen was very interesting because of the fact that it was either very sick or wounded by our shooting at a spot near there at dusk. When first seen in the brilliant moonlight it was flying like a butterfly very slowly and irregularly into the small breeze that was blowing and toward the water hole. As it flew past me I made a strike at it with the net but missed, the bat flying off to one side and then into the water hole. I turned on the flashlight and watched the specimen hover very slowly over the water and then fall in after an at- tempt to drink. The specimen swam to one of the dirt walls, climbed a few inches up the side and then fell back into the water.
