1916 | Camp: Subspecies of Sceloporus occidentalis 69 
the Museum of Vertebrate Zoology from Inyo County seem to indi- 
cate that western Inyo County is the locality in California where 
intergradation between slansburiana and elegans takes place. Table I 
shows how the number of scale rows increases as one goes north 
through Owens Valley.

OF UTA S. STANSBURIANA AND U. S. ELEGANS 
Mus. Dorsal seale

3105 Mohave, Kern Co. 83 elegans

Pass, at 6000 feet, Inyo Co. 99 intergrade 
6072 Laws, Inyo Co. 93 intergrade 
Average of three specimens, Benton, 
Mono Co. 102 stansburiana 
Average of fifty-five specimens,* Utah, 
Nevada, Idaho, and Oregon 103 stansburiana 
* According to Richardson (1915, p. 418). 
Counts of seale rows in twenty specimens of stansburiana picked 
at random from series collected at a number of points in the San 
Joaquin Valley and in San Luis Obispo County indicate that the 
subspecies occurring in this region is hesperis, rather than elegans, 
as Richardson (1915, p. 414) has indieated. The intergradation be- 
tween hesperis and elegans seems to occur at such places as northern 
Los Angeles County, Walker, Cajon and San Gorgonio passes, and 
eastern San Diego County. This is shown in table IT.
