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



Sceloporus zosteromus Cope. 



This large lizard is apparently distributed throughout the entire 

 peninsula of Lower California. This species resembles the preceding 

 and may prove to be only a variety of that species. Sceloporus clarkii 

 B & G, which does not occur in the region under discussion, is quite 

 distinct from either. From my study of the material of this group in 

 the museum I am led to accept the views of Dr. Stejneger.* 



Specimens of this species were taken in the following localities: 

 San Jose, Matomi, Rosarito, and San Quentin, Lower California. 



Sceloporus orcutti Stejneger. DUSKY SCALY LIZARD. 



This lizard is common in the northern part of Lower California, 

 where it attains about the same size as does 5. zosteromus. 



It was also observed by Mr. Heller to be quite common at Los 

 Encinos, Lower California. 



Specimens were secured at the following localities: San Salado 

 Canon, Trinidad, San Matias, Agua de las Fresas, Canon Esperanza, 

 Parral, Matomi, Rosarito, and San Antonio, Lower California. 



Sceloporus biseriatus Hallowell. FENCE LIZARD. 



This very variable and widely distributed species is quite as 

 abundant as any of the genus in the region treated of in this paper. 

 "It is usually found on trees or shrubs, frequently at an altitude of 

 8,000 feet." 



Specimens were secured at the following places: Beveridge Canon, 

 Lone Pine, Hot Springs, Coso Valley, Coal Kilns, Hannopee Canon, 

 Wild Rose Springs, Piru Creek, and Ft. Tejon, California; Hansons 

 Lagoon, Trinidad, San Jose, Santa Rosa, Rosarito Divide, and San 

 Antonio, Lower California. 



This species was also seen by Mr. Heller at Santa Tomas and Los 

 Encinos, Lower California. 



Sceloporus graciosus Baird & Girard. MOUNTAIN LIZARD. 



This species has a considerable vertical range. "It was seen on 

 Telescope Peak at an altitude of 10,500 feet. In the Inyo Mountains 

 it was abundant on granite boulders and in sage brush at from 7,000 

 to 8,500 feet. A few were seen at Ramshaw Meadows at 9,000 feet, 

 and in Lockwood Valley near Ft. Tejon." 



Specimens were secured at the following localities: Beveridge 

 Canon, Coal Kilns, Hot Springs, and Telescope Peak, California; 

 Agua de las Fresas, Vallecitos, and La Grulla, Lower California.
