REPTILES AND AMPHIBIANS OF TEXAS 17 



southern portion of the State. I have not met with 

 it personally. The published records are Laredo and 

 Ringgold Barracks (specimens in the National Mu- 

 seum collection, listed by Cope), and Rio Grande 

 City (Bailey). 



34. Crotafhytus wislizenii Baird and Girard. Leopard 



Lizard. 



Trans-Pecos Texas, apparently not common. The 

 Baylor Museum specimens were collected at El Paso, 

 where it is said to be rather more abundant than in 

 the country further east. Bailey records it from 

 Boquillas, Brewster County, and Toyahvale, Reeves 

 County, and Brown included it in his list of the rep- 

 tiles of Pecos. 



35. HOLBROOKIA TEXANA Troschel. Texas Zebra-tailed 



Lizard. 

 This handsome lizard has a very entensive range, 

 being distributed over fully two-thirds of the counties 

 of the State. It is very abundant in the trans-Pecos 

 region, in the granite country, and in many of the 

 counties of Middle-Southern Texas. It is also found 

 in some of the east-central counties, but in these it is 

 very locally distributed. In the Panhandle and south- 

 em plains district, it is confined to the rocky breaks 

 and canyons. Tarrant, Bosque, McLennan and the 

 line of counties extending southward seem to form 

 the eastern boundary to its range. 



36. HOLBROOKIA MACULATA Girard. Spotted Lizard. 



This species inhabits the western half of the State, 

 east to Wichita, Parker and Bexar counties, south 

 to the Rio Grande. It is most abundant west of the 

 foot of the plains and in the trans-Pecos region. 

 Many of the records for this species have been hope- 

 lessly confused with those for the variety lacerata 

 and the species propinqtm. All of these have been re- 

 ported from San Antonio, probably as the result of 

 mistaken identifications.
