 SCELOPORUS MAGISTER (Hallowell). 



Locality. — This large scaly lizard was observed at Derby, the Pyra- 

 mid Lake Indian Agency, and at several points along Pyramid Lake 

 as far as The Willows. Specimens were collected at the points men-

 femoral pores are fewer in number. Four Arizona specimens ex-

 Basin. They show a very pronounced broad dorsal stripe of black
