Murray 1948 Thomomys Bottae June 3, 6 mi N San José del Cabo, 250' H, Baja Calif. Have put out 10 traps, 5 in the sandy flat area around camp, where it is impossible to tell which mounds are fresh. The other 5 are in a corn field among the rows of corn, and where there has been regular irrigation. Here all were fresh workings. Caught 3, one in the morning, 2 in the afternoon. All were from the traps in the cornfield.
