6 mi. N of Caduca, 9600 ft, Hidalgo, Mex. June 30, 1946 west on a road turning off just beyond the guard station. We drove about 1 1/2 miles west on the road but were stopped by an inundated section of the road, so stopped and walked a few hundred yards to the ramp ground, which the guard had called "Las Salinillas". Just above the ramp ground are several jagged columns of rock, called "Peñas de la Ventana". We heard and saw several thrushes, pro- bably Catharus, Black-headed Grosbeaks, one of which was killed by an Indian boy with a slingshot and given to us, many Robins, and several large and brilliant-green Hummingbirds. Returned to the truck and turned off the road, proceeding about a hundred yards down a grassy meadow bordered by Abies religiosa with a dense Juniperus under- story. The terrain here consists of fairly dense stands of second-growth Abies, with scattered patches of Juniper growing beneath the pines. The wooded terrain is broken by numerous open, grassy meadows. The grass is quite green, but close-cropped, as there is much livestock in the area. We saw several herds of cows, and flocks of sheep and goats. Plants noted include Fefina, Diglyphium, Bee-plant, Baccharis, scattered Madroño, small patches of oaks, Elephant-heads, a red Pentstemon which is very common, and small cacti around the "Peñas".
