Murray 1948 Journal May 6 Bahía Concepción, 13 mis E Mulegé, Baja Calif. and a shell fragment gravel. 5 were on a salt flat section next to the mangroves with salicornia, some large leafy bushes- very salty crust. 15 were on an arm of shell fragment gravel which extended up the hillside among large rocks. There were a few palo verde, copals. 15 were on a fairly flat area of small rock at the base of the hillside where I trapped before. Vegetation was thin - mostly creosote and copal. May 7 Same locations There were 2 Perognathus spinatus in the 15 traps along the cliff; 1 spinatus in the salt marsh (edge, 30 ft. from rocks), 1 on the shell fragment hillside. Those among the rocks were empty but about 8 in one group were spring. Saw 2 oyster catchers flying close together, giving shrill crys. They dropped down close to the water and flew quite a distance in that manner. Today we got several large conches from a fisherman and tried them for lunch. They were a little tough but fine eating. Caught with a long rake and a row boat. We left in the afternoon, traveling on a very rocky road partly on the cliffs
