7. Crotalus adamanteus Beauvois. 

 Diamond Rattlesnake. 

 According to Mr. J. D. Mitchell in his report on 

 the Poisonous Snakes of Texas, the eastern diamond 

 rattlesnake was formerly abundant in Calhoun, Har- 

 ris, Jackson, Lavaca, Matagorda and Victoria Coun- 

 ties. In view of the hiatus existing in the known 

 range of this species, I incline to the belief that these 

 specimens must have merely represented a darker 

 and more distinctly marked coast race of Crotalus 

 atrox.
