LIDICKEN 1959 night. Rem trigline before going to bed. July 27 Catch: Peromyscus maniculatus - 9 Bassonings - 4 Saginawus lepidorus - 1 (pair) Dr of the fellows from La Labor brought us 2 pair specimens. ? Rattus rattus. We try to skin catch but we were bothered so much by Mexicans that we quit skinning & packed up camp & left about 1330. Nedd shot a Monotes mexicana, a froggy owl, & a resident ? genus in this camp & saw several more hot-nuts. On way back to Colilla we saw a number of Cittellus variegatus along rock walls. About 4-1/2 mi. north N of Colilla we saw a pair of Bist-white Cross the road & Dave got them both with 1 shot. We continued E toward Aguas calientes, then turned S on the road to Villa Hidalgo & shot way W of the city. We began checking for the estate line & finally found it approximately (although there was some disagreement among our informants). We returned N until we were about 3 km. N of the boundary & camped. This is an open area with scattered shrubs & small trees & some prickly pear, but with ground almost completely covered with greass. We saw what must have been a Cittellus sahelozona right near camp. After setting up We returned to previous camp to pick up 3 rimula bags which I had forgotten yesterday.
