reddish form of this species. These specimens, after remaining in spirits for 

 nearly two years, could be readily distinguished from the large series from 

 other localities that were contained in the same jar. When pursued, these 

 lizards make no attempt to escape by entering the burrows of other animals 

 but usually run from rock to rock until after they have been routed out several 

 times and then make a final break for the cover of weeds and brush. I ha.ve 

 chased them into water and for a distance of three or four yards they can swim 

 fairly well. Central Texas examples of this species do not display as bright 

 colors as those in the Trans-Pecos region, even during the breeding season. 



Cnemidophorus gularis Baird and Girard. Western Lined Lizard. 



This species is as common in the hills as it is along the streams and in the 

 lowlands. Along rocky roadsides it is usually found in company with Cro- 

 taphytus collaris and Holbrookia texana. 



On the south side of Post Mountain I shot several adult lined lizards marked 

 exactly like sexlineatus, with no traces of light spots between the lines and 

 with fewer femoral pores, but as they had the long muzzles of gularis and the 

 ante-brachial plates were present, I refer them to the latter species. 



Vta ornata Baird and Girard. Ornate Lizard. 



This handsome little Uta is tolerably common on trees and rail fences be- 

 young Clear Creek. A few examples were collected on rocks near the mouth 

 of Spring Creek. My specimens are probably the first to be recorded from 

 any locality in Central Texas. 



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



In some localities this interesting species is quite common, in others exceed- 

 ingly rare. Specimens were collected in the following places: Sherrard's 

 Ranch, Post Mountain, Clear Creek, Morgan Canyon, and at the mouth of 

 Spring Creek. 



In August, 1902, a large number of these lizards were collected around the 

 bases of small trees and in brush heaps on Post Mountain, but when I revisited 

 the same place four years later a single immature example was all that I could 

 find. 



Sceloporus spinosus Weigmann. Texas Scaly Lizard. 



This tree lizard is common and a large number of examples were collected. 

 These differ greatly from those from the northern part of the State. Ex- 

 am.ples from the latter section have a dull greenish ground color and the mark- 

 ings are not as well defined. None of the Burnet County specimens show the 

 slightest tinge of green, the lateral stripes vary from white to buff-yellow in 

 different individuals and the markings (especially the transverse bars in the 

 female), are coal black and unusually distinct. Several old specimens collected 

 on rail fences in the woods were almost black. 



Phrynosoma cornutum Harlan. Texas Horn'^d Lizard. 



A few examples of this species were collected on the flats near Burnet but
