specimen from Riceboro, Ga., also apparently belongs here, 

 length 140 mm, shell dark brown with narrow radiating yel- 

 low stripes; yellow on the keel not forming a continuous 

 stripe. Plastron dark brown with light variegations. Head 

 with round yellow spots, no stripes, zygomatic arch complete, 

 claws on the hind feet three, and a notch showing termina- 

 tion of fourth digit, hind feet somewhat webbed, shape of the 

 shell much as in the two Tallahassee specimens, perhaps a 

 little shorter in proportion, flaring outwardly behind. 



Terrapenc ortiata* This has the shell flatter and broader 

 than the other forms, always without a keel. Color light 

 brown with narrow radiating yellow lines on the carapace 

 plastron brown, marked with yellowish lines arranged in 

 regular pattern, posterior to the hinge they are mainly long- 

 itudinal while anterior to it they show a tendency to become 

 transverse, zygomatic arch always incomplete. Hind claws 

 always four. Hind feet always unwebbed. Some speci- 

 mens, apparently males, have the first claw on each hind 

 foot turned forward, while others, apparently females have 

 it normal in position. 



I may mention apropos of nothing that male tortoise 

 have longer and thicker tails than the females, this feature 

 is strongly marked in the genus Kinosternon, for instance 

 and less strongly so in all Emydoid turtles I have examined. 



Terrapenc mexicana. This species I have not seen, its 

 range is apparently confined to Mexico. 



The range of the different forms of Tarrapene is rough- 

 ly as follows: 



Terrapene Carolina. North-eastern U. S. east of the 

 Mississippi, south to the Carolinas. 



Terrapene tnungis. Gulf coast and Mississippi valley 

 from Georgia to the Rio Grande, North to Missouri. 



Terrapene baurt. Florida and southern Georgia. 



Terrapenc major. Gulf coast, Georgia to the Rio Grande. 



Terrapene ornata. Rocky mountains to Lake Michigan 

 and Indiana, south to Chihuahua; in the southern part of its 

 range it does not come east of Texas.
