under logs in an open glade in the forest. Port Orford cedar 
and Douglas fir were dominant, with a heavy undergrowth of 
blackberry and tall ferns, and, in the open, dry grass a foot 
or more in height. The temperature was high during the mid- 
dle of the morning when the lizards were collected, but they 
were apparently not feeding at this time of day. All but one 
were found under logs. Although they were not especially active 
or quick in their movements, most of those that were discovered 
escaped into thick cover. When the tail of one was broken 
as the animal was captured, the disconnected member performed 
such lively movements that for a moment both observers who 
were present mistook it for a fluttering moth or butterfly. Most 
of the logs which offered suitable hiding places for the lizards | 
were too large to be moved and consequently it is probable that 
only a small fraction of the lizards actually present were seen, 
yet in some places several were seen within a few square yards. 
The stomachs of seven specimens taken at this locality contained 
10 small beetles, 1 crane fly, 1 noctuid moth, and 1 snail. 
Females containing developing ova were taken as follows:

Shasta Alligator Lizard 
Gerrhonotus coeruleus shastensis 
This subspecies ranges from sea level up to at least 6800 
feet and from the sea-coast more than 200 miles inland. Its 
subjection to a wide range of environmental conditions is re- 
flected in its variability. It usually chooses for a habitat a well 
drained situation where there is abundance of decaying wood 
on the ground, preferably where bushes, trees, and open grassy 
places offer a variety of forage within a small area. Often it 
is abundant along creeks. 
On June 29, 1932, I collected specimens at Grass Valley 
Creek, Trinity County, California. The weather was warm and 
the lizards were active but during the middle of the day they 
kept in the shade beneath the thick growth along the creek, 
consisting of maple, alder, ash, yew, Douglas fir, blackberry, 
willow and tall ferns. Many lizards were found several feet 
above the ground crawling along nearly horizontal branches or 
logs. One individual first seen on the ground attempted to
