untagged adult male olivaceus; Trap #20 untagged male olivaceus sexually immature; Trap #30 a smallish female olivaceus with open vagina. This makes a total of at least 5 mice on the 1-ha island: 4 olivaceus and 1 longipilis. Two of them were tagged on the first day, one olivaceus recaptured 50 yards away, but neither of the tagged mice was recaptured in the final two trapping sessions. Also picked up the 12 small Shermans on the way back to the car. They held one more Ako olivaceus that I overlooked on the morning check. Then drove to the main trapping area 4.7 km NE of the Termas de Puyehue road fork and checked the Museum Special traps that we had set on the road shoulder. Anita's held 2 olivaceus and 1 longipilis. Mine held nothing. My 10 cage traps held nothing either. Anita set 20 more Museum Specials back in the woods. These are in addition to her original line of 34 Shermans in the woods and 20 Museum Specials along the road. Then we cut a short trail back into a big clump of dead quila that looked like it had been dead for at least 2 years. There was also some 1-year blooming big quila there also. Underneath the dead-dead clump was lots of rich mulch a rotten log, but no sprouts or seeds. I set 10 Shermans there in an area of only 15 X 15 ft. George Vallerini drove past while we were setting traps along the road, on his way to Valdivia to meet Patricia. Home at 8 pm. No rain all day, mostly sunny. November 13- Aguas Calientes, Chile. Morning overcast. Various trap lines in the morning: Milton and Freddy in their 170? traps had 2 Ako olivaceus. My 10 Shermans in the "dead" bamboo clump had nothing. My 10? cage traps along the road had 1 Ako longi; my 2 cage traps along the road had nothing. Anita's 20 and my 15? Museum Specials along the edge of the road at 4.7 km NE had 7 Ako olivaceus, 4 Ako longi, 1 Auliscomys, and 2 Oryzomys. We are both being bitten by leeches, probably along this ditch. Another unusual feature of trapping around here is the abundance of very small flour beetles robbing the rolled oats in the Sherman traps, especially those set around the bloomed quila. Are they part of the bamboo seed cycle? Started raining after lunch, sometimes hard. We all drove up to the ski lodge at Antillanca through quila, macrostachya, culeou, and finally montana at the lodge. This does not include the culeou-like species in the sphagnum bog. The montana is definitely knobby- jointed and numerous culms are zig-zaggy. A km or so below the lodge is a grassy airstrip? with Chelemys- sized burrows in it and a few small earth cores; also
