Returned to Bariloche at 6:30 pm. nov.22 Bariloche. Sunny day. nov.23 Bariloche. Drove out Peninsula San Pedro looking for good Oryzomya habitat. Found lots of Rosa mosqueta near the confiteria Salva Negra. Sunny day all day. Then drove to Gloria Suiza on the back road from the bridge across the ravous of Lago Moreno. Passes through a stretch of scrubby overgrazed vegetation on pale sandy soil that looks like it might have Aebdon fortbordinus and maybe Elydromys. Saw no tusks digging but they should bother. In afternoon set 28 traps in an abandoned pear orchard being invaded by Rosa, some tree in bloom, other part. Half musser species, half big Sherman. nov.24 Bariloche. Sunny. Traps held 9 Abedone, no Oryz. 3 in musser species. Numerous small slips on the boots. Yesterday at Gloria Suiza saw near its lake two large Eucalyptus (not blue gum). How to tell Abedones apart: longifilis usually has rusty color on back, belly more silver (plateado), tail thicker, body larger. Olivaceus color is indeed more olivaceous, belly darker, browner, tail thinner. Xanthorhinus usually has a slightly tawny upper lips, belly paler than olivaceous, body smaller than longi, back color paler than olivo. nov.25 Day sunny. At 6 p.m. left Bariloche and set traps about 1 km west of the bridge across the Rio Casa de Piedras, 14 km W Bariloche. Habitat was scrubby with Rosa mosqueta, Retamo, Zizela brown, rosol, Berberis darwinii and portoi, acacia, strawberry, Rhea, grass, Mutisia, Baccharis, occasional bandos but only a few
