Quast 1948 Balantiopteryx plicata June 2 Cerro Cirildo, 600+ ft, 4 mi N San Jose del Cabo, Baja Calif. Eight ♂ and two ♀ put up today after they were caught at above location by Drs. Benson and Tavis. Both females had one embryo of 14 mm. June 5 9mi S.W. San Jose del Cabo, 300+ ft, Baja California Visited cave here located in weathered granite outcrop at an elevation of about 300 ft (estimated). Cave faced approximately north and was about ¼ mile from the ocean. It was found to be approx 15 feet long and twelve feet high and pear shaped in cross section, tapers being at its top and broadening to about 4 feet at its entrance base. One could see directly from the entrance to the back and it was one of the most open of caves containing bats that have been visited so far. About 20 of this species were seen in the back of the cave in a pot hole in its top. They flew when approached and only four were obtained. Two flew into a long crevice at the cave's rear but escaped by us. The floor of the cave contained many droppings and its walls were damp from urine in several places about 3 feet in diameter. Large wings of flying insects were visible on the floor, but our guide said that the cave was also visited by bats of a larger size. Put up one of four caught - ♂ # 312.
