26. PREFACE. 
with remarks. The vernaculars are compiled from different 
writers who have written on New Jersey amphibians and rep- 
tiles, together with such as I could gather myself. Nearly com- 
plete references to each species, as credited from within our lim- 
its, are given, as far as I could find up to the present time. Of 
course the general nature of some of the works will indicate 
the distribution of a-species without mentioning that it has 
ever occurred in New Jersey. In several of these cases it is 
probable that the author’s studies were at least based in part on 
New Jersey material, aside from what may be mentioned. From 
the fact that great activity in zoology centered about Philadelphia 
formerly, it may be naturally inferred that the animals then 
studied were largely known from the environs of the home local- 
ity. This is especially the case with Harlan and others. 
I am under great obligations to the Academy of Natural Sci- 
ences of Philadelphia for the use of its library and unexcelled col- 
lection of New Jersey amphibians and reptiles. In the laboratory 
of that institution all of the species represented by specimens were 
drafted, besides affording additional advantages for comparison 
with the fine series of specimens from other localities. The col- 
lections of this institution émbrace possibly some of the most 
interesting amphibians and reptiles extant. Most of the orig- 
inal types described by Jacob Green are still in good condition, 
and some have been included in this report. Samuel Ashmead 
made collections at Beesley’s Point, most of which were studied 
by the earlier naturalists. Dr. Charles C. Abbott made very 
important collections about Trenton. Prof. Edward D. Cope 
also made several collections at different places. Mr. Samuel 
N. Rhoads made fine collections, principally in the northern part 
of the state. Mr. Witmer Stone, together with Messrs, J. A. G. 
Rehn, H. L. Coggins and others, made various trips to the pine- 
barren and southern regions with sticcess. Finally, the writer, 
during his various fishing excursions, visited many localities as 
already enumerated last year, together with many others, and 
has thus been enabled to gather a lot of information. Many 
notes were made in the field which are included in this work, 
especially those with reference to fresh or living examples.
