Journal Hafner, M.S. 1976 6 mi. N, 31 mi. W Hiko, 4800 ft., Lincoln Co., Nevada 18 September (cont) which species. Some facts about the system; It had several entrances - all of which were plugged. The soil lining the burrow - even at its greatest depth (ca. 450 mm.) was dry the surrounding "matrix" was moist. The burrow seemed to turn much more than I remember in Dipodomys and Perognathus ; ie. instead of bifurcating at a turn, the burrow would simply wind around. Dipo. burrows were generally straight lengths connected together like pipes. I followed the burrow to the soil depth, which was ca. 450 mm. below the surface. I found the presumed nest chamber although there was only a small handful of bedding - and little other evidence. I noted young scorpions and crickets. The nest chamber appeared to be ca. 60 mm in diameter and had a cache of what appeared to be Atriplex seeds in a small side pocket. I thrust my hand into a side pocket near the surface looking for more tunnels and unearthed a very large scorpion (ca. 120mm in length.). This rather surprised me and I curtailed operations. 1000 - 1400 Took tissue, stomachs, reprod. tracts etc. and prepared the animals. Warm day.
