P. PEARSON 1952 swallower disappeared during afternoon rain-they didn't even seem to know it was raining. Morning with very little sun, rain in afternoon, light rain in evening. Jan 20 SUN. Traps did 1 Heefierump, 2 juvenile Ph. bolivianus, and 3 adults. The Heefierumps out on the pampa not near any holes. Wonder they show up in owl pallets. At breakfast with bus conductor counted 15 ps of swallowers on the pampa. After some photography left for Tutupaco and was greeted by Juan Pujas again. Planned for a time, then drove off on a dead bent road toward Torata, then out the Rio Viecho road. But wrong got stuck, so took home again. Then set traps in some nice rocky hills just east of Tutupaco village. Lots of vicuella droppings, but also lots of craves and deep cavey place with brush cultivation, big genevioa, Poo persoonii? etc. Evening calm with some stars. Jan 21 Traps did well, 1 Ph. bolivianus, 5 Chiroumps, 6 Phyllostus dominii. The two on this rocky upletter hill was almost all Seladophyllum quadrangulare, and quite abundant. at our camp 5 mi. E of Jogo deche, some altitude, L. rigida was by far the more abundant and in the T sateras (Vaya cerro they call it). Have seen quadrangularis at least to 15,000 ft., sometimes growing in midst of a clump of rigidum. Left about 6 a.m. on mine truck up to the mines. There apparently only go a few hundred feet higher than the Panthera turnoff, which gives them a range up to 15,300 +/- Vegetation gets scarcer as you go up and above 16,000 is.
