Pearson - 1991 of grey foxes. Also a flicker. Then drove to various Diques looking for Abrothrix/Chelemys habitat. Black-necked swans on one of them. Never got to any good habitat on the road back to Presa Los Reynos but parked under a pepper tree and skinned. Then to Presa El Tigre and found some fairly mesic habitat near the river, with pampa grass, but it didn't look any better than close to Fort San Rafael itself, so drove to the Fort again. Saw scissor-tailed flycatcher nearby and lapwings, and heard horneros, so a considerable pampa element. Put out 3 tuco traps, and three lines apiece in the habitat between Fort San Rafael and the river (which is essentially dry because the dam upstream diverts the last of the flow into an irrigation canal). We each had three lines through pampa grass, assorted bushes, weeds and grass. Light sandy soil mixed with river rocks. Anita's 3 lines totalled 28 traps and mine totalled 35 traps. Anita found a few droppings that looked like guinea pig. Then drove a couple of miles east of town and camped in the monte desert. Partly cloudy. November 25.- Night partly cloudy. Our traplines were untouched, except the tuco traps caught one tuco and one big toad. Set 6 more tuco traps, then skinned etc. until about 10:30 when we picked up the tuco traps: 1 more tuco, a baby. The soil in the tuco areas is light sand with scattered river stones, but in other places there are too many stones for tucos. Lunch in 25 de Mayo, then to the Museum in San Rafael where they let us stay in one of the guest rooms. The electricity was off, so the exhibits were hard to see. The staff artist, Francisco Mora (Pancho) showed us around. Dr. Lagiglia showed up at about seven and showed me some small mammal specimens and some material from Cueva del Indio on the road to Valle Grande at 600m. Included was a Reithrodon skull and lots of Thylamys (Marmosa). He calls Ctenomys "Tunduque". November 26.- San Rafael. Worked in the Museum in the morning, identifying skull fragments from owl pellets. Lagiglia's daughter, Flavia, does the taxidermy and knows where the specimens and data are. Identified some owl pellet material from Cerro Nevada south of San Rafael (the daughter says from Rincon del Atuel). Dr. Lagiglia showed up later with walkie-talkie in hand directing the museum. His librarian brought in a stack of rodent reprints for me to look over: Roig, 1965 Mammals of Mendoza p 185 Fig. 5 says Akodon longipilis from Malargue. Massoia? and/or Contreras in Historia Natural No. 29 says olivaceus beatus at Los Aguaditos in San Rafael Dept. (6 specimens), pellet material I think. Numerous localities for molinae near San Rafael in Contreras and Rosi His. Nat. 1980 #26. I must check up on molinae vs. Abrothrix. Could be that molinae is not a good species. Left the Museum about 11 and headed for Chos Malal. Between Sosneado
