1916] Camp: Subspecies of Sceloporus occidentalis 67 
to be intermediate in size and color between this form and a series of 
S. 0. occidentalis at hand from western Mariposa County. In the 
Yosemite Park this subspecies lives on rocky, sunlit slopes in the 
heavily glaciated region in the upper Merced basin, about Lake 
Tenaya, and in the head of the Tuolumne Canon, at altitudes between 
7300 and 8200 feet. 
NOTES ON SCELOPORUS GRACIOSUS 
The representatives of Sceloporus graciosus isolated upon several 
of the mountain ranges of southern California south of Mount Pinos, 
Ventura County, appear to constitute a locally differentiated race. It 
is here proposed to reinstate the name vandenburgianus (Cope, 1896, 
p. 834) for this subspecies, the type locality of which is the ‘‘ Summit 
of the Coast Range, San Diego County, Calif.’’—probably in the 
yellow pine belt on the Laguna Mountains, San Diego County.

Diagnosis.—hLike S. g. graciosus, but adult males with blue belly- 
patches united across mid-line, or else separated by a very narrow 
interval only; belly-patches confluent with throat patch; undersurface 
of hind limb and tail dark blue; the lighter, broad, mid-ventral line 
and chest-patch of graciosus, indefinite or absent; blue of underparts 
sometimes nearly black, usually darker than in graciosus. Females 
more dusky in color beneath than females of graciosus.
