Murray 1948 Depodomys merriani Apr 13 Punta San Felipe, 50± ft., Baja California. A number have been taken in live traps by the others in sandy desert or washes. The traps are primarily mouse size however. All my traps have been on rocky slopes. Apr 12 9 mi W San Felipe, Baja California 700± ft. Went hunting in the desert at about 10PM and found two rats, both of which were much confused by the light- almost caught one by hand. They could not seem to find holes to go into and could not seem to make up their minds which way to go. Often they would run into a bush and right out again. The night was clear but moonless (see journal). Many burrows and tracks had been seen in the daytime. Apr 15 Cerro Centinela, 300± ft., 13 mi WSW Mexicali, Baja Calif. Had 50 live mouse traps out in a sandy wash which ran below the mountain. Through most of it were bars of small rock, and ironwood, creosote, indigo brush and several others were present in moderate quantity. Checked the trap line at 9 PM last night and found 4 rats which I released. This morning there are 7 more rats. I only caught one Peromyscus Perognathus formosus along with them. Put up 3, 2F and 1F, releasing the others. There was a moon through early night.
