 green bordered with black. The throat is black, mottled 

 with green. The under surfaces of the thighs are green,

Distribution. This species is known only from the Cape 

 Region of Lower California, where it has been collected at 

 San Jose del Cabo, Corral de Piedras, Sierra El Taste, Mira- 

 flores, Sierra San Lazaro, San Antonio, Todos Santos, 

 Guamuchil Rancho, Cabo San Lucas, Agua Caliente, San 

 Bartolo, Triunfo, and La Paz, and from Espiritu Santo 

 and Ballena islands. 



Habits. This species generally is found among the rocks 

 in small arroyos and seldom is seen upon the ground. Being 

 extremely shy, it will not allow one to approach nearer than 

 fifteen or twenty feet, wheh it makes a hasty retreat to 

 some nearby crevice or rock-pile.
