Quart 1948 Journal April 11 Punta San Felipe, 50' ft., Baja California Murray and Tevis and saw many bats fly-ing along the beach and circling about the hill above camp. They looked like two species, and were probably Pipistrellus leporinus and Tadarida mexicana. Murray shot one Tadarida mexicana. The Pipistrellus seem to be as-sociated in loose groups of 4 or 5, while the much bigger Tadarida flew singly. Tevis located a well about 300 yds from the beach in the gully S.W. (San Felipe side) of camp. The mouth of the well has silted in so that it is about 20 ft in diameter and thus is only what looks like two inches of brackish water in the bottom, 9:15 P.M. A strong gale has come up from the north and the air is full of dust. This evening while we were shooting bats at the beach we noticed a large school of fish breaking water in the shallow off-shore water. The fish jumped and made the water boil about 50 yds from the beach for about an hour. Dr. Benson tried to get some of them by plug casting, but was unsuccessful. The fish appeared to be three or four feet long. We plan to change the location of our camp tomorrow to some other place in this area, the location depending upon the roads.
