Lilleland 1933. Itinerary, 18 July 11- very plentiful in this canyon. E.R. Hall, J.D. Durrant and F.W. Gorham all of whom trapped in the valley W of our camp (about 3 mi) took: 173 specimens out of about 300 traps set. These were mostly Microdipodops megaceph- alus, Perognathus nevadensis and Peromyscus manicu- latus. On this same date I trapped one Neotoma lepida - female with young, as indicated by enlarged mammaries, also two Peromyscus maniculatus. The Neotoma lepida had a bot fly larva hanging partly out of the skin ventrally in the neck region. This I preserved. Shot a Eutamias cerialis as early as 5 30 a.m. before sun had reached the N. side of canyon wall. Left Camp Hot Creek (Camp 3) at 2 10 pm. We first drove to the Willow Creek Road; then realizing that barometer had not been checked we returned to camp. Trucks went on. Found altimeter 200 ft. off due to change in pressure. Travelled by way of Fish Lake (conspicuous alkali deposits) to Greenmonster Canyon. About 4 15 we came to the Ranch home of an Indian in canyon. This was the most attractive spot we had come to or seen.
