S Phrynosoma modestum (SJA 206) 4.3gm.; 73mm. (42mm) taken ~ 3 inches above ground in sn. dense scrub x ~ 12:00 noon. Several Cuenidophorus sighted; one shot (SJA 207). While stalking one Cuemid, he (?) made semicircle of 12" radius while flittinging laterally. Thought @ 1st this gesture was directed @ me but found instead a Crotaphytus wrighti among mesquite (?) branches @ center of 'Cuemii' semicircle. Two C. wrighti taken (SJA 204-205) & 2 others sighted. #205 had particularly lg. stomach mass. While I shot, Sage got a few body temp doses on U.exul. Extricting shot Una from mesquite in time for valid weighing was a major problem, vicious spines.
