PREFACE. 
Besives the gentlemen already named as having aided in the preceding volumes, 
I must now acknowledge my obligations to those who have assisted me in this, 
the fifth and last volume of the external forms, colour, habits, &c. &c. of our 
Reptiles. 
To Dr. G. Mavran of Providence, Rhode Island, I am indebted for many 
Salamanders, and especially for a beautiful Salamandra longicauda. 
To Dr. Storer of Boston, for the description of the Salamandra salmonea, a 
new species, discovered by Dr. Binney among the Green Mountains. 
To 8. 8S. Hatpeman, Esq., of Pennsylvania, well known by his writings on 
Conchology, I owe many thanks for “observations” on the habits of the different 
kinds of Reptiles, as Tortoises, Lizards, Serpents, &c., and especially for several 
Salamanders, some of which are hitherto undescribed. 
To Professor Benepicr of Burlington, for some excellent remarks on the 
Menobranchus maculatus.
