yc- 1933. 85 SW part Walker Basin, Kern Co., - Nov. 3, 1933. - middle of the basin. In the latter area were many small holes which I took to be perognathus inornatus. How- ever, none of these 12 traps were even touched. Maybe the perognathus have left? From my ten traps in the thistle I took four dipos and one peromyscus. From my willow line I took one dipo and three peromyscus. I shot two horned larks, one robin, one nutall woodpecker, one barn owl (badly shot), and two dark sparrows. 320 Peromyscus sonoriensis ♂ wt: 21 150-74-22-19 321 Peromyscus sonoriensis ♀ wt: 22 165-77-19-17 322 Dipodomys agilis ♀ wt: 66 290-170-43-19 322(a) Dipodomys agilis ♂ wt: 67 300-180-47-18 323(b) Dipodomys agilis ♀ wt: 70 305-183-44-18 324 Dipodomys agilis ♂ wt: 67 300-175-43-18 - Nov. 4, 1933. - For some reason I'm not getting the mammals out of here that should be here. Perhaps it is because the basin has been cul- tivated too much, or maybe because the basin is too well grazed by sheep. Anyway the traps I have set in sand draws, sand- lupine associations, and sand-thistle
