Alligator Lizards 25 
escape by climbing up the vertical trunk of an ash tree eight 
inches in diameter, with bark only sufficiently rough to offer a 
good claw hold. With two or three pauses the lizard climbed 
straight up to a height of ten feet, then turned and started back 
own. When it was touched with a stick by the observer, it 
of the creek, in open woods of black oak and yellow pine, 
failed to disclose any specimens, A single G. multi-carinatus 
scincicauda was found foraging near the creek and apparently 
oe the same niche as the more abundant Shasta Alligator 
izards. 
On June 27, 1932, I collected a number of specimens, includ- 
ing the type, near Burney, Shasta County. Alligator lizards 
seemed to be quite limited in habitat and were found only in, 
or at the edge of, a small meadow, either moving through the 
short grass or hiding under scattered logs and boards. When 
found, they were easily caught by hand and apparently had 
no system of escape. The grass was high enough to impede 
their progress without offering concealment and the ground was 
hard and packed, with no cracks or holes. The lizards were 
seemingly at the mercy of any enemy which could turn over or 
get beneath the small pieces of wood under which they con- 
cealed themselves, or catch them in the open. Among possible 
enemies may be mentioned the rubber snake (Charina bottae) 
which was also found in the meadow. No Gerrhonotus could 
be found in the surrounding open woods of yellow pine, although 
conditions there seemed favorable, judging from my experience 
in collecting the lizards elsewhere. 
A racer (Coluber constrictor mormon) taken near Kuntz, 
on Mad River, Trinity County, on June 12, 1934, was found 
to have eaten one of these lizards. 
On March 31, 1932, I spent most of the day hunting 
Gerrhonotus at Lyonsville, Tehama County. The day was warm 
but there were still patches of snow in sheltered spots and the 
ground was damp everywhere. Sceloporus and Eumeces were 
already out abundantly, but apparently Gerrhonotus was not yet 
fully active, as only two were found. 
On July 11, 1932, specimens were collected near Lake of the 
oods, Klamath County, Oregon, at an altitude of slightly over 
feet, in typical Canadian Life Zone, lodgepole pine and 
Ceanothus velutinus being the dominant plants. There had been
