Uta Stanshuriana elegans (Yarrow). 
Several specimens were taken during the first week in April, and they seem to be 
farily common throughout a large part of the Mojave and Colorado deserts, in Cali- 
fornia at least. 
Sceloporus magister (Hallowell). 
One specimen taken 35 miles east of Mecca, California, April 2, 1920. Other 
specimens taken during July and August, east of Holtville, California. These lizards 
seem to prefer the brushy country or the neighborhood of trees, into which they 
climb when frightened. The specimen taken east of Mecca was found on the ground 
beneath a cactus. 
Phyrnosoma platyrhinos (Girard). 
Representatives from five miles west of Amboy and Needles, California. Without 
an exception they were found on the dry gravelly washes or in the sand not far from 
washes. 
Xantusia vigilis (Baird). 
Three specimens from east of Victorville, and one from the Providence Moun- 
tains, near Bonanza King Mine, March 30, 1920. These specimens were all found 
beneath the bark of prostrate yuccas. 
Cnemidophorus tigris tigris (Baird and Girard). 
These lizards appear to be one of the most common found on the Colorado and 
Mojave deserts in California. Their range is extremely varied, specimens being 
taken from, and between, Victorville, Needles, Blythe, the Mexican border in Imperial 
Valley, and Palm Canyon. These localities are not given as the limits of the range 
‘but places within the range from which we have specimens. Specimens were taken 
in the Salton Sink 265 feet below sea level, and from the Providence Mountains at an 
approximate altitude of 2,800 feet above sea level. 
Sonora occipitalis (Hallowell). 
One specimen taken at the grass-fields, between Blythe and Mecca, California. 
When taken it was traveling out in the open and in the heat of the noon sun, April 
3, 1920. It was found on a gravel wash and when approached it struck in all 
directions, though apparently it did not open its mouth upon striking the hand. It 
appeared to be blinded by the sun and unable to tell from which direction it was 
menaced. 
Bascanion flagellum frenatum. 
Two specimens, both taken near Mecca, Imperial Valley, April 4, 1920. Both 
these specimens were somewhat lighter than specimens taken from the region around 
Claremont, California. 
One of these snakes was obtained under rather unusual circumstances, which 
incidentally involved the collecting of a Cnemidophorus tigris tigris. The lizard was 
shot but not killed by the collector, and while watching for an opportunity to kill 
the lizard without the use of a second shot, the snake was seen gliding in the same 
direction as the lizard, and suddenly attacked and seized it, when both were added 
to the collection.
