collected... near the steam pump eighteen miles north of Tucson
they seem to come out late in the afternoon, and then appear on the tops of boulders, where they may be seen bobbing up and down as many lizards do
found always on the ground in the open desert, while the other species secured frequents canyons and hillsides, and is usually seen on the top of large stones or boulders
found at the steam pump eighteen miles north of Tucson
its habit of constantly wanting to get up on the tops of boulders attracts attention to it in life.
very common on trees and wood bridges
we found them on trees, fences, and piles of stones
some were found lying along the limbs of mesquite trees and some were in low, thick-growing bushes on the sand hills east of Yuma
found on rocks in the oak and conifer belts
found in cracks in the granite boulders
also taken on a boulder
on trees — on willows — on mesquites — on oaks and pines
under the eaves of an old adobe barn
found in an old adobe bouse
near the steam pump in the foothills of the Catalina Mtns., eighteen miles north of Tucson
on willow trees in the river-bed
while at the steam pump they frequented the wooden fences about the corral
found also in a wash on the desert near the mouth of Ramsey Canyon
in the river-bed at Tucson
also at Oak Creek
from the top of Mt. Lemon
in the pine belt
on the sand hills east of town. One was found sitting on an ant hill, but not an ant was in sight although a half hour later they were swarming over it. It seemed as though the ants remained under cover in the nest as long as the lizard was watching for them.
caught in a wash on the grounds of the Desert Laboratory
found out at any time of the day
found in the giant cactus, creosote bush, and oak belts. All found were merely walking about. They hasten their gait when one approaches them, but were never seen to run. Two put in a pillow case and hung in a tree, scratched a hole through the cloth and escaped.
found in the oak belt, on the ground among stones and dead leaves, walking about in the day time, and were very shy
found under a stone about a foot square, and about twenty feet from the edge of a pool of water. Under the stone the earth had been worked from between the grass roots, showing several runways in one of which this snake was coiled up
dug out of the sand at the base of a bush on a dune two or tree miles east of Yuma... It was about a foot below the surface
caught in a peach orchard near the pine and oak belts in Ramsey Canyon... found just before dusk as it was entering a hole by the side of a fence post
in the pine belt
from the pine region
from pine woods
captured in the bed of the Santa Cruz River near Tucson... apparently mating. They were lying on the sand at full length but entwined. When disturbed they immediately separated and instantly mounted to the top of a willow tree some twenty feet high, where they were captured with much difficulty...
captured in the oak region
one was found under a stone, one on a wall of rock, and the others on fairly open ground.
dug out of a hole in a sand hill east of Yuma
found under some boards near Yuma
found in the water or on the rocks in the stream
shot in Sabino Canyon
collected in the foothills of the Catalina Mountains near the steam pump eighteen miles north of Tucson
caught in mud puddles on the desert a mile or more from the river
caught at about 4 p.m. in a pool near the ditch. It was swimming several inches below the surface of the water, seemingly in pursuit of the little fish which were very numerous in the pool. The snake soon coiled up under some brush at the edge of the pool, and there we captured it.
collected at Oak Creek... a mountain stream running through a deep canyon with many oak trees... found in the stream, either on rocks or in the water
removed from the stomach of a Diadophis regalis caught in Ramsey Canyon...
near the steam pump about eighteen miles north of Tucson... caught about four p.m. just as it was entering a hole in the ground
