Perognathus ♀ 17.2-G. 12/4-40-22-6 Same as above. 182. Peromyscus ♂ 11.8G. 17/6-10/-21-18 Caught in bare rocks in foothills. 183 Perognathus ♀ Rocky draw in alluvial fan. (in formalin) 184. Perognathus ♀ Same as above. (in formalin) 185. Icterus bullockii ♂ (im) 26.0G. Killed while sitting in willow. (skeleton only) The 13 traps set among the rocks in the foothills caught only 3 Peromyscus which were so badly eaten by ants during the night that they were worthless. Found a single white egg in a depression in the rocks. It was about the size of a large pullet egg and was set in a large round space with a few vine stems around it. Probably it is the nest egg of a C. a. septentrionales. Caught a Geococcyx californicus in the steel set but it was too far badly mutilated to be used as a specimen.
