Ana and Mill creek, on the brushy slopes from lower Bear creek 
to Clarke’s ranch, and above the latter point along the road lead- 
ing to Bluff lake, nearly to 7500 feet altitude. But this latter 
record, based on a specimen taken July 15, 1905, was still within 
the scrub oak belt on the south slope. Fenee lizards were num- 
erous about Seven Oaks and less common up the Santa Ana along 
the hot north wall of the valley to 6000 feet at least. They were 
also noted among boulder piles on the desert at the north base of 
the mountains, where specimens were secured August 11, 1905. 
A female fence lizard noosed July 26, 1907, near our Cedar 
Cabin camp on the upper Santa Ana, and chloroformed and 
dissected at once, contained in its stomach one lady-bird beetle, 
one leaf-hopper, one spider, one geometrid larva, two wood-ants, 
and several unidentified insect fragments. 
Sceloporus magister Hallowell. Rough-sealed Lizard. 
This large species was found to be common among boulders 
and tree yuceas on the desert around Cushenbury springs and 
Box S springs at the north base of the mountains. I ‘‘auxed’’ 
several specimens in that loeality, August 11, 1905, both adults 
and young. 
Phrynosoma blainvillii Gray. Blainville Horned Toad. 
Horned toads were actually abundant in the dry open places 
along the upper Santa Ana above Seven Oaks. Especially on the 
south exposure among the scrub oaks and rabbit-brush, numbers 
were seen in July, as many as a dozen being noted along the trail 
in an hour. TI collected specimens as high as 6200 feet altitude 
near the mouth of South Fork. June 12, 1905, the species was 
met with along the road through the brush belt between Bear 
creek and Clarke’s raneh, 3000 to 4500 feet altitude, and examples 
were preserved. 
Gerrhonotus scincicauda (Skilton). Alligator Lizard. 
Alligator lizards proved fairly common along the upper Santa 
Ana, particularly in the Upper Sonoran brush-belt along the 
north wall of the valley. Specimens were noted, several of them 
being preserved, from the vicinity of Seven Oaks, 5000 feet al- 
titude, to the south face of Sugarloaf, 6800 feet. Several were
