TEXAN HERPETOLOGY 13 



differently colored. The ground color is less buffy and the back is ornamented 

 with five red stripes, a dorsal and two lateral ones on each side. Between 

 these stripes are numerous, closely placed brotches of the same color. 



TJta stansburiana Baird and Girard. Stansbury's Lizard. 



Prade collected a single example of this brown-shouldered lizard in the arid 

 strip beyond Elephant Mesa. It was the only one seen by us. Bailey does 

 not record it from any locality in Brewster County. 



Uta ornata Baird and Girard. Ornate Lizard. 



This species was quite abundant in Du Bois Canyon and at Paisano, where 

 they were living among rocks. Several females captured in Du Bois had the 

 throat colored orange instead of blue, as in the male. Recorded by Bailey 

 from the Chisos Mountains and Altuda. 



Sceloporus torquatus poinsettii Baird and Girard. Poinsett's Lizard. 



Recorded by Bailey from the Chisos Mountains and fifty miles south of 

 Marathon. We found this fine Sceloporus quite common among rocks on the 

 Blackburn Ranch. When pursued these lizards seek refuge in narrow crevices 

 and will permit themselves to be pulled out piecemeal in preference to relin- 

 quishing their hold. 



Sceloporus spinosus clarkii Baird and Girard. Clark's Lizard. 



Boquillas (Bailey). This variety of spinosus is confined, in Texas, to the 

 Trans-Pecos Region. 



Sceloporus consobrinus Baird and Girard. Marcy's Fence Lizard. 



I captured an example of this little fence lizard on an old corral near 



Paisano Pass. Prade collected a second along the road past Elephant Mesa. 



Sceloporus merriami Stejn. Merriam's Lizard. 



One specimen from Boquillas is recorded by Bailey. 



Phrynosoma cornutum Harlan. Texas Horned Lizard. 



We collected specimens of this species near Alpine and in the arid strip be- 

 yond Elephant Mesa. Bailey records it from the Grand Canyon of the Rio 

 Grande. 



Phrynosoma modestum Girard. 



Examples were collected about five miles out from Alpine and at various 

 places along the route to the Chisos. 



The ground color, in the series obtained, was very variable, ranging from 

 light buff to rusty brown and almost coal black. 



I have every reason to believe that this species, like the horned lizards of the 

 douglassii group, is viviparous. 



Coleonyx brevis Stejn. Banded Gecko. 



I collected a single example of this little Gecko in the Chisos foot-hills. It 

 was running around among rocks on a hillside, just before dusk and on account 

 of its rather feeble movements was easily captured. In the living specimen the 

 bands were brown and sulphur yellow.
