TEIID^. 



57. Cnemidophorus sexlineatus Linn. Six-lined Lizard. 



Eastern, Central and Northern Texas. Without 

 an examination of the specimens, it would not be pos- 

 sible to tell whether some of the published records 

 refer to this species or Cnemidophorus gularis. In 

 many of the central counties, both species occur in 

 the same localities, but occupy different habitats. 

 Near Waco, gularis inhabits the fields and grassy 

 flats while sexlineatus seems partial to wooded bot- 

 tom lands. Brown records this lizard from Pecos but I 

 have never seen examples from that far west. Cope's 

 Galveston and Bailey's Padre Island records indicate 

 that this species ranges through the coast country 

 clear down to the mouth of the Rio Grande river. 



58. Cnemidophorus gularis Baird and Girard. 



Spotted Race Runner : Western Lined Lizard. 

 Central, Southern and Western Texas, its eastern 

 range overlapping that of Cnemidophorus sexlinea- 

 tus. It must also occur in the northern portion of 

 the State as it is quite a common animal in Central 

 Arkansas and Oklahoma. Specimens from Waco and 

 other east-central counties are much larger than the 

 majority of West Texas specimens. The smallest ex- 

 amples in my series are from the canyons of the 

 southern counties of the Panhandle. 



59. Cnemidophorus tessellatus Baird and Girard. Tes- 



sellated Lizard. 



Trans-Pecos Texas, southeast in the Rio Grande 

 valley to Laredo and probably further. Bailey re- 

 cords specimens from the Castle Mountains in Crane 

 county. 



60. Cnemidophorus perplexus Baird and Girard. Seven 



lined Lizard. 



This species inhabits the region south and west 

 of the Pecos river, but apparently does not range east
