 Chelydra (Genus) 



79. Chelydra serpentina (Linne).

 This form has habits similar to those of the 

 preceding. It often engages in overland pilgrim- 

 ages and sometimes raids the barnyard. Smaller 

 than temmincki but may weigh 25 pounds. 

 TESTUDINIDAE (Family) Clemmys (Genus) 



80. Clemmys guttata (Schneider).

 Eastern U. S. Feeds on both vegetable and ani- 

 mal life. 



Emys (Genus) 

 81. Emys blandingii (Holbrook). 

 BLANDING'S TURTLE. 

 This semi-aquatic form bridges the gap be- 

 tween the entirely aquatic species, which can only 

 take their food when submerged, and the terrestri- 

 al forms which eat only on land. It can take food 

 either way. 



Terrapene (Genus) 

 82. Terrapene Carolina Carolina (Linne). 



BOX TURTLE. 

 A terrestrial species which can entirely with- 

 draw its head and limbs into its shell. This gives 

 it complete protection against any natural enemy. 

 Is herbivorous, and, like other terrestrial Testudi- 

 natians, attains a great age.
