PREFACE. xi 



To Miss Martin, of Charleston, my thanks are also due, for some accurate 

 and very spirited drawings of Carolina Reptiles. 



To the Reverend John Bachman, of Charleston, I am indebted for many 

 interesting remarks on the habits of our Reptiles, particularly those of the 

 Alligator. 



I have to thank Professor Jacob Green, of the Jefferson Medical College of 

 Philadelphia, perhaps more than any of my friends, for observations on the 

 Ecaudate Batrachian animals, the habits of which family he has investigated with 

 great success; and also for the use of his notes on the Reptiles generally. 



Charles Hammond and Ogden Hammond, Esqs., of West Chester, New York, 

 have also furnished me with beautiful specimens of the Emys picta, with remarks 

 on their hibernation. 



Major Leconte has, with a liberality that distinguishes the true lover of nature, 

 rendered me essential service in placing at my disposal his notes on Reptiles, 

 accompanied with beautiful drawings, the labour of many years. 



But, above all, I am indebted to Dr. Charles Pickering, of Philadelphia, who 

 has aided me with his accurate knowledge at every step of this work. 



The work will be arranged in two parts: — 



Part I. treats of the external forms, colour, habits, geographical distribution, &c.
