Herrn, H. 1980 30 may one was under a small lava rock prospect (cont.) ~ 10 cm above sand, out on the lava flow. after supper, four cars hunted the blacktop road from Newberry Springs to Anchoy. Got several Chionactus, 1 Phyllodictylus, ?/0 C. cerastes, 2 Arizona elegans, 1 Dipsosaurus, and 4-5 Coleonyx. The chionactus have yellow interspaces that are fringed w/ orange or rust color. The one found crawling on sand in the lava at 5:56 1830 hr was purplish gray w/ a faint reddish middorsal area. 31/may walked along the creosote flats, up into the lava flow and back to camp from ~0830 - 1/30 hr. Saw numerous lizards: Phrynosoma platyphinos (1 just was grey gray- black all over), Uta, Dipsosaurus, Gymnodophorus (several traveling in pairs), Urosaurus gracilis, Sauromalus, Grotaphytus ficirostris (a pair, ? w/ orange spots, both very melanistic) and Callisaurus. One student saw a Gopherus on the lava flow. After lunch we had demonstrations on thermal and exercise biology led by Paul Ticht (C. tigris was run to exhaustion in 14 sec.!). Then went to Jeff Kaufmann's apartment in Newberry Springs for showers. At about 1600 we walked from our campsite w/ to Jeff's Ursa study
