9. Cnemidophorus sexlineatus. Linn. 
Six-lined Lizard. Swift. 
This small species occurs, but it so closely resembles the smaller speci- 
mens of Cnemidophorus gularis , that without a large series of swifts for 
examination, it would be difficult to say whether it was common or rare. 
10. Liolepisma laterale. Say. 
Ground Lizard. 
A common species in the wooded districts where it lives among logs, 
masses of decayed wood and fallen leaves. 
11. Eumeces quinquelineatus. Linn. 
Red-head. Blue-tailed Lizard. Skink. 
Occurs, but as far as my observations go is quite rare. I have only 
taken two specimens, and have seen but three others. 
12. Diadophis regalis arnyi. Kenn. 
Arny’s Ring-necked Snake. 
One specimen. East Waco. 
13. Heterodon plaiyrhinus. Latreille.

Apparently not common. 
14. Cyclopliis aestivus. Linn. 
Southern Green Snake. 
A common species in the wooded districts. 
15. Zamenis constrictor. Linn. 
Racer. Black Snake. 
Both the black and yellow forms occur. 
16. Zamenis flagellum,. Shaw. 
Coach-whip Snake. 
Common. I collected several and saw others at Cottonwood creek this 
year. Here they feed largely on Rock Lizards. 
17. Coluber spiloides. Lumeril and Bibron.

This large Coluber is one of our commonest snakes, especially in the 
timbered sections of the county.
