Mymal Leong 1969 journal 115 35 mi. ENE Nasca, 10500 ft., Depto. Ayacucho, Peru Sept. 7 (cont.) we are now rising at 5:45 and it gets dark at 6:15. Perhaps it is the change in longitude latitude. I first noticed this when we were camped near Chanccay. 8:30pm. I went to check my traps. In a snap trap set at the entrance to a little rock cave (entrance 5"x6") was a freshly caught Phyllotis of some sort. The ears are large and the pelage is lax and surprisingly light colored. It was dead, but still warm. (MAL 389). The tuftle is longer than the body. Perhaps it is one of the asp of Phyllotis darwini or Phyllotis boliviensis. Nothing yet in Koford's traps. The night is cold and clear and windless on the whole. Sept. 8 6:00am checked my traps. I had 3 more mice like the one I caught last night. One small male was caught in the trap I reset last night after taking the mouse out. The other mice were caught also in holes in the rocks & under rock shelves. I lost my second steel trap. Dr. Koford and Ray each caught 2 mice of the same kind of Phyllotis. Ray saw about 4 vicuñas in the rocks by the road. It is very dry up here. There was no condensation or frost this morning. Last night was cold. I discarded a female mouse 20g. with uterine scars, because it had a crushed skull. Possible size diminution? We left at about
