Arnold 1937 Primitive area, Berkeley, Calif. Dec.22, I went to the primitive area this morning in the rain. I did not attempt to take very many notes because of the weather. I did notice, however, that the traps contained more dead mice then previously. This is probably due to the fact that there was not enough food in them even though there was enough cotton. The following numbers were marked: #15 Ad. Peromyscus truei gilberti in trap 8 #16 Ad. ♂ Peromyscus truei gilberti in trap 11 * #18 Ad♀ Peromyscus truei ♀. in trap 13. * #20 Ad.♂ Reithrodontrmys - repeat in trap 20. Ad♀ Peromyscus truei dead in trap 15. * #19 Ad♀ Peromyscus truei gilberti - repeat in trap 20. * #13 Ad.♂ Reithrodontrmys repeat in trap 26
