Habits. The Brown-shouldered Lizard is a ground- 

 loving species usually found in open fields or deserts or 

 among rocks. Upon the approach of an enemy it 

 quickly retires to some hole or crevice and shyly peeps 

 out from time to time to see if the intruder has de- 

 parted. At the old mission of Santa Barbara these 

 graceful little lizards are especially tame and abundant, 

 and live among the stones of the walls and fountains, 

 darting in and out of the crevices which once were filled 

 with mortar, sunning themselves on the sheltered sur- 

 faces, or chasing one another with all the abandon and 

 apparent delight of children playing tag.
