Eumeces skiltonianus
July 25 Nest No.5 (cont.) (Found on grassy slope of
west side of San Pablo Ridge about 100' from top)
and the uphill side was being broken down with
a pick. Breaking it down involved picking out
the larger rocks, then picking down the remaining
dirt and rocks. As I broke away some dirt and
rocks a large skink ran out. I caught her and
at the same time noticed some eggs (5). The
eegs were partly covered by fine soil that had
almost certainly sifted in while I was digging.
The eggs were in such light soil that covered
a rock floor. The layer being about 1/2" thick.
They were lying at what was then (result of
my picking) the mouth of a tunnel about 30mm
in diameter that sloped up at about a 15°
angle along a rock floor and rock wall
on one side. The tunnel extended only 20cm.
The large rock that, when removed, exposed
the nest was within 10-30 mm of the eggs,
and projected out of the ground about 30 mm
on the uphill side and 300 mm on the downhillside.
It was one of the 25 or 30 rocks that marked
the outcrop and attracted me to the spot to
start digging. The parts of the other rocks
were from 15 to 35 cm. in diameter and
projected 5 to 30 cm. above the surface. This
outcrop was concealed by grass from an
observer 50-100
feet away. A 50± gram sample
