REPTILES FROM SOUTHEASTERN ARIZONA. 34I 



longitudinal dorsal band so often seen in S. magister r 

 and the latter is never so generally bluish above as S.. 

 clarkii. 



The number of femoral pores varies from ten to four- 

 teen in S . clarkii, from three to four in a large series of 

 S . boulengeri. The coloration of the latter species is 

 also very different, there being a distinct light line along 

 each side of the back. 



Sceloporus magister Hallowell. 



Numerous specimens of this large lizard were obtained 

 at Fort Lowell in May and June, 1893, and in May, 1894. 

 It was not seen elsewhere. 



Sceloporus consobrinus Baird & Girard. 



Twenty- one small Scelofiori from Fort Lowell, Fair- 

 bank, and Upper Rucker Canon in the Chiricahua Moun- 

 tains seem to belong to this species. I have not been 

 able to compare them with specimens from near the type 

 locality. All have two very distinct light lines along each 

 side of the body. The dark dorsal area usually shows 

 small blotches of dark brown, but may be unicolor. 

 Males have a blue patch on each side of the throat. 

 Femoral pores vary from twelve to sixteen on each side. 



Sceloporus scalaris Wiegmann. 



Mr. Price's notes indicate that this is a rock- dwelling 

 species, and that it occurs at great altitudes. The spec- 

 imens collected furnish, I believe, the most northern 

 record of its range. They are quite typical, and were 

 collected near the summit of the Huachuca Mountains, 

 May 22, 1894, * n Morse's Canon, April 7, 1894, and "at 

 an altitude of 9500 feet" in the Huachuca Mountains, 

 July 22, 1893. 



Prof. Baird recorded this lizard from Los Nogales 

 (Mex. Bound. Surv., p. 6).
