Murray 1948 Callieaure draconides Apr 11 Punta San Felipe, 50 ± ft., Baja California Have seen a number of them here, though not really common. They have all been on sandy desert terrain with encelia, ocotillo, and creosote. Characteristically, they permitted me to approach no nearer than about 15 feet, then rushed off at high speed. Frequently zig-zagged, tail curled over back. Usually they stopped just short of a bush and watched, with head and shoulders raised up high. After that almost any movement was enough to send them the rest of the way in. Apr 28 30 miles SE Mesquital, 600 ± ft., Baja California In the course of about 1½ hours hunting saw 23. The ground was mostly hard packed rocky surface with some sandier areas. Mostly cholla, ocotillo, yucca and some cardone with brush; many open spaces present. The lizards exhibited much the same behavior as above, though often less timid. Usually the only way I saw them was after they rushed off from 10 or more feet away. They ranged from about 10 to 30 feet at one quick rush, almost always stopping in the open just before entering a bush. Two or three steps then were enough to frighten
