Carl, Blin 1976 Journal 5 mi. E. Bishop, Inyo Co., California August 22 550 Last night I set 94 Museum special traps on the study grid (10 X 10 m grid, 100 meters square). I established .8 mi. East of White Mountain Research Station. Traps were set at grid markers and baited with peanut butter. It was clear, warm, and windy, with an almost new moon. Results: 1 Perognathus longimembris, 3 P. penicillatus (?), 1 Perognathus merriami juv., and 1 Pipidolona merrioni. D650 2 mi. E. Big Pine, Inyo Co., Calif. Came to Big Pine at 7:30 PM to trap SE of Junction of 164 & Wacoba Valley Road; set 4 parallel lines of 24 traps at ca. 20' internals. Habitat here is mixed scrubland, brushy. It has been windy for over 24 hrs, so this may be productive, as wind eliminated about 700 f.m. Traps baited with peanut butter and set at base of bushes, as usual. Soil here much sandier, few to no rocks, as compared with Bishop localities. August 23 Retrapping traps at 6:00 p.m. Total catch = 2 mule deer, 1 Pipidolona merrioni, 1 Perognathus longimembris 1 mi. E. Lane, Inyo Co., California August 24 75 Set 94 Museum specials a bit south of my previous locality. Washed traps today and on using "natural" peanut butter as bait. Set in 2 loops; 1 E., the other W. of road leading
