We are camped in several wave-worn caverns by the beach of a small bay connected to Bahia Concepcion (Conception Bay). The drive from Mulege yesterday took about an hour over fairly good road. Seen along the trip were: Vermilion Flycatcher and an Osprey, one Jack Rabbit and an Antelope Ground Squirrel. 49 live traps set in rocks above sand flat east of camp last night caught 4 Perognathus spinatus and two Peromyscus cremicus. Caught by others in addition were Neotoma lepida and Phoenathus arnensis and one Dipodomys merriami. Conception Bay is surrounded by high hills of lava rock. Mangroves grow around the esteros and Cardone, Pitaya, Mesquite, Cholla, and Creosote in the sandy wastes. Elephantaphrium is found in the lava rock of the steep hills. Mounds of shells are almost continuous along the many beaches of the bay's perimeter. Birds seen today included one Osprey, two Oyster-catchers (One shot by Dr. Benson) and a Frigate Bird. The water team will fish, large and small, but so far Dr. Beman
