Aug. 31 Cuernavaca highway, 8700 ft., near La Cima, Distrito
Federal, Mexico.
Although there does not appear to be a permanent
stream. Water may seep up from around the rocks,
or there may be a sub-surface basin. In any case
I noted several small standing pools of water
in the bottom of the depression. In some spots
the combined mix of grass and standing water
create a situation very much like a small patch
of marsh. - On the slopes of the hills or rises, a
medium sized pine occurs in pure stands (3/
needles; needles about 4-5 inches in length).

grass is not of wide distribution in their immediate
area. This particular patch of it is rather peculiar,
inasmuch as I did not see a like situation in
driving from Cuernavaca to Mexico City.
The most conspicuous bird was Aristocris
superiorius, which occurred in scattered flocks
throughout the bushel-cactus. When flushed or
disturbed they often flew to the nearby pines.
Several Junco phaeonotus foraging in the bushel
glass. No Xenospiza seen; no sign of any small
sparrows other than Junco. - After hunting for
1 1/2 hours through the bushel grass, I hunted along
the lower edge of the pine forest. Here I encountered
mixed a flock of Sitta pygmaea, Parus sclateri, and Picidang
olivaceous foraging in a pine. Collected 2 Sitta pygmaea
