J. Rodgers - 1942 30 Eumeces shiltonianus July 20, (cont.) 1942 Mrs. Vert. Zool., Univ. Calif., Berkeley, Alameda Co., Calif. pocket that are formed alongside of the outcropping rocks. The pocket probably formed by slipping away of the soil around, by erosion of the soil around the outcrop, or by receding of the outcrop itself than erosion. A combination of the first and last, with the second playing some part seems probable. Although it seems unlikely that much slippage has taken place in the hill here since it is mostly shale clear to the surface, not with a thick top layer of soil as noted on hillsides where slippage commonly takes place in those hills. Although we found no skinks in this place, it seemed to us like a good place for them and an easy place to dig. We found one adult male skink about 75 yards NW of the point just next to the power line and within 30 feet of the top of the ridge. It was under a rock that we won about 4" x 5" x 8", and part of a cluster rocks of that size & smaller. The fact that the eggs of nest no.1 have probably shrunk suggest that these nests are being kept too dry. This is supported by the fact that the egg in nest no.2 had a dent in the side of it two days ago when it was very dry but appears normal now and by the fact that, this we found no nests in the hill
