50 EMYSHIEROGLVPHICA. 



Troost, of Nashville, Tennessee, has furnished me with a living specimen from the 

 Cumberland river. 



Habits. We know but little of the habits of this animal, but from its structure 

 it appears to be eminently aquatic. 



General Remarks. I have been led to give the name hieroglyphica to this 

 species from the peculiar disposition of the yellow hnes and spots on the marginal 

 plates, which at a first view bear a strong resemblance to hieroglyphic characters.
