REPTILES FROM So. CALIF. AND L. CALIF. MEEK 9 



Lone Willow Springs, Pilot Knob, and Lanes Mill, California; San 

 Quentin, Lower California. 



Crotaphytus silus Stejneger. SHORT-NOSED LEOPARD LIZARD. 



"Common in the San Joaquin Valley north of Rose Station, 

 where they are found living in abandoned burrows of the Kangaroo- 

 rat, Perodipus. They do not leave the level floor of the valley, but 

 extend to the base of the hills near the mouth of the Canon de las 

 Uvas. The species is very wary, which is doubtless due to the open 

 and exposed nature of their habitat. All the stomachs examined 

 contained grasshoppers. 



The adults in life were bright lemon yellow on the belly and under 

 surfaces of the limbs and tail. Above they were cross-barred like 

 the young of C. wislizenii, of which their coloration is probably an 

 arrested stage." 



The throat of this species contains much less black than that of 

 the preceding. There is usually in the center a longitudinal dark 

 stripe with a few irregular elongated blotches on each side. On the 

 throat of C. baileyi the black is arranged in several longitudinal bands. 



Specimens in the collection were secured at Rose Station, Cali- 

 fornia. 



Sauromalus ater DumeTil. ALDERMAN LIZARD. CHUCK-WALLA. 



"This is the largest lizard native to the State of California. It is 

 reported to be common in mid-summer in the rocky canons of the 

 mountains near Daggett, and in the rocky canons entering Death 

 Valley. This species is common in the Panamint and Inyo moun- 

 tains, from their bases to about 6,000 feet. It is much sought for by 

 the Panamint Indians for food. Their method of hunting them 

 consists of searching the cracks in cliffs, from which retreats they are 

 secured by means of a wire hook inserted in their bodies. It probably 

 nowhere exceeds an altitude of over 6,000 feet. 



"This species is reported to occur in the summer in the desert 

 ranges of the northern part of Lower California." 



One specimen was taken at Beveridge Canon, one at Furnace 

 Creek, and two in Hannopee Canon, California. 



Uta mearnsi Stejneger. MEARNS' LIZARD. 



This species is quite plentiful in the northern portion of Lower 

 California. Specimens were collected at the following localities: 

 San Salado, San Matias, Canon Esperanza, Parral, and Matomi, 

 Lower California.
