Dalquest 3540 " " 3541 " " col. by W.W. Dalquest The above eight skinks and four alligator lizards were collected by Garth Murphy, Walt Dalquest, and I, collected in 1 1/2 hours. All were cold and inactive, and under rocks. No. 3540 was taken about 500 feet higher up on the hill. The ground was much drier under the rocks up there than on the hillside where the rest were taken. On this trip and on the one to the same place on Dec. 17, I rolled over 1000 more rocks in the under bay trees & found no skinks, no other reptiles, and but several Batrachians and an Aniedes. Just out beyond the limits of the tree, where there is enough light for grass to grow, more skinks have been found than in any other part I this area. Three of the Gerrhonotus were found under Eucalyptus logs & one was found under a rock under Eucalyptus tree.
