PREFACE. a 
I am indebted to the State Museum of New Jersey and its a’ te 
Curator, Mr. Silas R. Morse, for assistance in facilitating tue 
work of this report. ‘To Dr. Charles C. Abbott, of ‘Treiton, 
for some information and assistance. To Prof. Ulric Dahlgren, 
.of Princeton University, for information on the salamanders 
about Princeton. ‘To Mr. Witmer Stone, for materials and 
notes on examples from various localities. To Mr. Wm. J. 
Fox, who has added much to the ichthyology of Sea Isle City, 
for notes principally concerning the marine reptiles of that 
region. To Mr. Thomas D. Keim, for much information and 
assistance when in the field during our many pleasant trips. To 
Mr. H. Walker Hand, of Cape May, for information and 
assistance while working in that region. To Mr. David Mc- 
Cadden, Mr. J. A. G. Rehn, Mr. Bartram W. Griffiths, Mr. 
Chreswell J. Hunt, Mr. S. Harbert Hamilton and Mr. George Z. 
Hartman, of Palermo, in Cape May County, and many others, 
for information or assistance in collecting specimens, 
The figures given in this report are mainly taken from those 
in the second edition of Holbrook’s North American Herpe- 
tology. Several have been taken from other accessible works, 
or drawings of my own. ‘The text figures are from Cope’s 
works on North American amphibians and reptiles. 
Finally, I shall state that though errors may occur in this 
work, no excuse is made in their behalf, and it is trusted that 
they are few and far. It is with the hope that it will be of use 
and value to those who are interested in the subject, and furnish 
an impulse to a new and more complete account in the near 
future.
