thus: ‘‘Minimum—maximum (mode)’’ m this and m all 
of the following summaries. Length of body, 38-111 (81- 
90); length of tail, 57-210 (151-165) ; total length 98-309 
(221-240) ; width of head, 9-29 (18-20) ; length of tail as 
percentage of body length, 57.1-72.5 (64.1-66); width of 
head as percentage of body length, 20.0-30.0 (22.1-24). 
Ellis and Henderson (1913) have listed this species as 
reaching the total length of 380 millimeters, which is 
greatly in excess of the length of the largest Kansas 
specimen examined by the writer. 
Habitat and Habits——Cope (1866) gave the habitat of 
this species as, ‘‘Sand, logs, among brush, etc.’’—Stej- 
neger (1893) found it to be ‘‘Evidently an inland desert 
form of the Upper Sonoran life zone.’’—Van Denburgh 
(1897) found that this reptile is a lizard of the desert, 
but that it does not seem to live on its lower levels, pre- 
ferring the more mountainous regions between the alti- 
tudes of 4,500 and 6,500 feet. Taylor (1912) wrote of 
Humboldt County, Nevada, specimens, stating that 
‘‘Hleven were taken near Big Creek Ranch at altitudes 
ranging from 4,800 to 5,400 feet. We look in vain for 
this species in the open desert and on certain of the lower 
- slopes of the mountains. All but one of the specimens 
were collected on the top of a steep sided rocky ridge.’’ 
Richardson (1915) stated that ‘‘The lizard was found 
only on hillsides amid deposits of tufa and outcroppings 
of voleanie rock at an elevation of 4,500 feet.’? In Kan- 
sas, collared lizards have been collected only between the 
altitudes of 800 and 2,200 feet, though there are points in 
western Kansas with an altitude of 4,000 feet. Bentley 
(1919) wrote that specimens were usually found in Nye 
County, Nevada, ‘‘On the large, flat rocks of a steep hill- 
side.’’
