Vor. III] VAN DENBURGH AND SLEVIN—ARIZONAN REPTILES 401 
April 16-22, 1912; eight at Tucson, March 28—April 13, 
1912; three at the steam pump eighteen miles north of Tucson, 
May 8-18, 1912; five at old Fort Lowell, March 29—April 4, 
1912; one from the Catalina Mts., Pima County; sixteen at 
Cave Creek, Maricopa County, April 5—May 17, 1910; and 
two from Dome, Yuma County, Jan. 20 and 21, 1910. 
The femoral pores in forty specimens, mostly from Yuma 
County, vary from twelve to seventeen; being 12 four times, 
13 ten times, 14 twenty-six times, 15 twenty-seven times, 16 
seven times, 17 once. 
All styles of coloration are to be seen in this series. Some 
have longitudinal light stripes, some have dark dorsal blotches, 
some are without large markings, but are sprinkled with small 
blue spots. A living male from Palm Springs, Cal., showed 
these various types of coloration at different times. 
23.—Uta ornata Baird and Girard 
More than three hundred and sixty specimens of these tree 
Utas are at hand. After careful comparison of individuals 
from Yuma and from eastern Arizona we are unable to detect 
any constant difference nor are we able to distinguish Arizonan 
examples from the few specimens from Texas which we have 
for comparison. We, therefore, make use of the name Uta 
ornata for all these lizards, and regard Uta symmetrica as a 
synonym. Our specimens are from the following localities: 
Yuma County—Yuma and Papago Wells. 
Maricopa County—Cave Creek. 
Coconino County—Oak Creek. 
Pinal County—Oracle. 
Pima County—Tucson, Fort Lowell, and in the Catalina 
Mountains at the steam pump 18 miles north of Tucson, 
in Ventana and Sabino Canyons, and in East Sabino 
Basin. 
Santa Cruz County—Mowry in the Patagonia Mountains. 
Cochise County—Fairbank, the vicinity of Ramsey Canyon 
in the Huachuca Mts., and at Cave Creek and Paradise 
in the Chiricahua Mts. 
The femoral pores in forty specimens from Yuma vary from 
ten to fifteen; being 10 three times, 11 eighteen times, 12 
thirty-four times, 13 seventeen times, 14 seven times, and 15
