acuta had 39 big + little shrews, mostly in the valley bottom; caught 1 marosa and 1 Phyllotis. The Phyllotis could care less about the vegetation at the bottom of the canyon, they liked the boulders on the slopes. All were carrying tules or rocks. Breeding males, juveniles and a pregnant female among those dissected today. Spend morning pelting lungs etc., afternoon sterning. Hot and sunny. 28° in the shade at 3 p.m. But 18 big shrews upon the north slope where the tules roll down the slope. Got a good look at a medium-large Lusionan while pelighting last night. March 22 May 18 shrews in what was good Phyllotis habitat cast night (all in rocks below the road shrubs) caught only one mus. Night partly with thin overcast but day clear and hot. Embossed lungs and dissected in morning, then visited with Hughes in Wolbrido. He calls our composite Oreboda Aqualina. He said there was some rain 2 months ago which produced a modest flowering, apparently enough to start the mice breeding. Then drove up the hill toward Arequipa. Vegetation best at about 1500 ft. At 1820 ft among green yellow daisies, white verbesinas, new florets of Zornetrelbia, at 2740 m is a feet peak with shrubbed cacti in the floor of the canyon along the old road best appreciated from the waffle end of the road. D drove until after dark and camped at 8 p.m.
